Why "Vortex" for Vortex math and devices?

If you are new to the topic then it might give you a slightly quicker understanding than watching hours of youtube videos.I assume you have seen these various coils that make a sphere shaped magnet spin at insane speeds.They are a good start.You see by normal understanding these Rodin or Vortex coils should not be able to produce a field that rotates that fast.As with a lot of things we tried to use math to explain it in theory and than adjusted the math to match it.Vortex math was born.So how do you explain blue and red to a blind person that never saw anything?I mean in a way they actually know how it would look if they could see?Doesn't work, but we can use a Dyson vacuum cleaner ;)A lot of "tornados" add up to one giant super tornado.Spinning so fast that "all" the dirst stays behind and only clean air comes out.As in nature all the weather cells add up to one that is more powerful than the combined single ones.The tornados that form the term vortex are around the coils.But also around the entire donut as well as every single strand of wire.In any good vortex the rotational speed increases towards the center and bottom of the vortex.You can try that with some floating stuff when you drain your bathtub or sink.Try to imagine and endless tornado that runs around every wire like a spiral.The coil itself adds another spin vector to it and increases the moving speed or the single tornado.Combined it adds up to a very strong tornadoe moving very fast around in the coil pack.As this also creates a rotating field like another tornado in the donut shape it all gets twisted up.Physics as we know it won't fully explain these effects.Vortex devices that produce electricity are usually coils in a special winding configuration and pattern.Like we try to eliminate certain things with basket coils in the HF area a Rodin or Vortex coil tries to utlise these otherwise unwanted stray effects and interferences.Overunity is another term people like to use here but I leave it up to you if such a things is phsically possible with an electrical system.Vortex math tries to explain all these things demonstrated in experiments.However I found two slight flaws in the common approch.1. Only two dimension used.Unlike the coils the simplified Vortex math only operates in two dimensions.A circle instead of a sphere if you like.2. Again, unlike the coil harmony and resonance are neglected.It seems in some cases people try to draw a circle just with straight lines.While in reality you have a never ending, resonant "stream" in three or to be precise four dimensions.Is it the chicken and egg problem?Yes and no.You can only calculate something if you can fully understand it or exactly replicate it in reality.Vortex coils are just way to interpret theories and get some sort of results.And those results are the real problem.We can measure magnatic fields in strenght and direction even frequency.However we can neither make them visible in real time not measure mixed or entangled fields properly.We "see" Mars is our "red planet" but in reality it just the atmosphere, the surface is not red at all in most places.NASA has enough problems to calculated missions to outer space with enough accuracy.Just imagine they would have to do it while considering that around every path our planets make is another spinning "distraction"....That is exactly what Vortex math tries to do while eliminating common math bit by bit.You can see and hear in 3 dimensions.Maybe you are also good in drawing something in 3D on your compterscreen or 3D headset.But how many here could predict the path of a baseball in 3D like they do when watching a game?Depending on your viewing angle you might be way off....Try to know or calculate where exactly the ball is at any given monet in time and how fast it spins in which direction.....Our brains are not trained to think like this!Even if we construct things like a dome we prefer to have straight features.Sure manufacturing is one thing that needs to be affordable.But try to just calculate the support structure if all is actually fully round like a sphere should be.We avoid what is considered higher dimensions as much we can.To calculate a distance in 3D it still seems easier to use two 2D models to add up instead of true vectors.Again only through technology like computer we are able to simulate, understand and actually calculate what we need.Where we ventured around the globe and into our solar system our math was left behind.Finding workaround and good enough approximations still seems the way to go.Instead actually evolving our math to our needs we just add more and more complex formulas and calculations.To fully understand vortex math you need to let go and start thinking in 4 dimensions instead of just 2.Oh, sorry, you might be new to this...Number 4 is time of course.

Vortex Tube expansion

So, i'd like to take the idea of a vortex tube and make it larger.  much much larger.  If i were to use a 3-4 inch pipe, how long would it have to be, and would i be able to supply it with a high power blower (centrifugal), or would i have to find some way to provide 80-120psi at a huge volume? i leave my question to the community!

Question regarding vortex cannon

I have planned to build a vortex cannon for shooting smoke rings. My questions are now: 1. Is it essential to have a round container? Or is a square card box as good? (there are no square smoke rings, or :-) 2. If it is round, does a short and big (in diameter), or a slim and long one better? 3. Using drinking straws on the exit, would this have an effect (in the style of laminar flow)? Thanks for your thoughts,

Vortex cooling / heating tubes

I am currently gathering information about vortex tubes for my repulsine project. There are plenty to choose from on a commercial base but I struggle to find any technical drawings with proper dimensions. Several home made varities can be found as well but wither with poor performance or incomplete drawings. So I was thinking that someone here either uses a commercial product at home or work and might be able to take some basic measurements for me? I am most interested in the relation between inner tube diameter and lenght for the hot and cold ends as well as the size for the vortex chamber itself. If there is an orifice used on the cold end the hole diameter would be required as well. My aim is, based on a properly working original, to create a device that might be less efficient but can be used without a compressor. Would like to see, correct transfer of dimensions given, a vortex tube like system was used in the repulsine. Some old documents state that there was a "seperator" which removed "heavy air particles" and created a temperature differencial between top cone of the repulsine and the wave disks.

Vortex Air / Vacuum Amplifier Help?!

Ok I need something to amplify my shop vac. I am building a cnc machine and I will have a vacuum attached near the cutting head. The problem is the distance of the pipe. The vacuum will barely be strong enough to pick up dust. I have seen some really cool vacuum amplifiers and air amplifiers that just run off compressed air. You get 25x what you put into it, but they want an insane amount of money for a machined metal ring. Here is what I am talking aboutwww.airtxinternational.comhttp://www.airtxinternational.com/catalog/air_amplifiers.phphttp://www.airtxinternational.com/catalog/high_thrust_air_jets.phpIt is all based off of the Hilsch vortex tube. There is an instructable on how to make one. They are just spinning the air to induce the surrounding air to move.There has to be a way to do the same thing or make these for a ton less than what they are charging. Anyone have any ideas?

3D printable Vortex Cooling tube

I am in the finnishing stages of my project now.The main body is now a single part :)My goal to create a vortex tube that works with very little airflow and/or pressure sadly failed so far.It is simply impossible to the required details printed.I might try again one day with a 0.1mm nozlze but calculations tell me I would need 2 days to print the body with it :(So what is the current status on the project?About 5 rolls of filament later I have now a single piece body that prints in one go with very little support structures required - none in really critical areas.Why now fully printed instead using ready to go aluminium tubing?Well...If these things start to work you can't really finetune the design anymore as they fail too quickly and start to leak.I got sick and tired of UV glue and epoxy glue as well...Metal expands differently than palstic when temps change drastically...Still the concept is far from perfect as I found out that printed parts only too often start to sepearte from the temperature changes - they start to leak through the layer even with 5 permimeters printed....Shortly after you break it all apart...Right now I went back to PLA with an outer coating of ABS juice or quick drying varnish.Once the surface gets cracks you know it is time to discontinue the testing and print another one.My best working model is now a conical tube, all up about 15cm long.I am able to reach a temperature drop from what comes out of the compressor to what comes out of the cold end of about 30°.Right now trying to work out the best orifice diameters and angles for the lowest posssible flow rate.Still it won't work for long on a cheap 130 liter per minute compressore from the home depot...Would love to have a much quicker acting thermometer, but I guess I will invest in one one day...As I somehow doubt I will manage to make work continously on a cheap compressor I might try instead to get a bigger temperature drop.Negative 5-7 is nice, negative 20°C would be better.I hope to finnish the testing over the next weekend and will then cnsider to make an Instructable from it.But who can properly test it out?Someone with a beefy compressor might not have a 3D printer or the other way around...Might try one day to etch the vortex generator and use glass tubes from droppers in a resin enclosure.In that size it certainly would even work from a fridge compressor but the cooling capacity would be very low indeed.Still, someone might need a -30°C spot cooler that can spot cool a pin head...

3D printed vortex tube for spot cooling

These tubes are available as industrial supplies by the dozen but quite costly.Tried a few designs available on the net but either they are next to impossible to print using FDM or fail to provide any significant temperature difference.Just to be clear: If amient air temp is 25°C then I would like to get below zero on the cold end.And well, I would like to be able to salvage a small fridge compressor with considerably less air flow than a shop compressor.Now to the problem(s) I face:1: The temp on the cold end is affected by both the length of the tube and by how much air can escape on the hot side.Makes finding a suitable diameter and length quite tricky if you don't have fancy simulation software at your disposal :(2: The standard cylindrical design for the "engine" is not really that efficient :(To make them work a lot of pressure is required, usually they won't do anything below 85PSI and most require about as much air volume as a little air grinder.3: 3D printed parts with complex insides are a true pain to clean, seal and make sturdy enough to last more than a few minutes under these conditions.I am currently experimenting with PETG as it is a bit more temp resistant and stronger.My understanding of these vortex tubes is that the outer vortex, created by the engine, travels up the tube.At the outlet valve the vortext is split so that the fastest and hottest air escapes while the colder air is directed dow, through the outer vortex and at a significantly lower speed for the rotation.Scientists can't really agree on the directions and spin of the inner and outer vortex :(My theory is that the hot air is created by a pressure increase towards the end of the tube.As this also expands the air, the inner vortex will be choked off so to say.Only option for it is to go through and by doing so loosing a lot of pressure on the exit - the stream cools down.The circulation around the vortex spin however means that speeds of well over the speed of sound are reached.I can only assume that at this speed there will also be some energy exchange happening based on the static electricity created where the two stream "rub" against each other.So far only models with a finely sanded inner tube actually performed at all.Will one day have to try using a thick plastic straw as a liner...Questions:1. Do you think a complex, conical nozzle is required?The commercial ones all use them.However I tend to think that a slotted approach might be better.Instead of adjusting the gap of the needle valve two half cylinders with slots can create a finely adjustable outlet.Way easier to desing if all parts shall be printable....2. If 1 is not a a real requirement:How to best design the slots for the correct air flow??In the direction of the rotation?Straight?Or even against the rotation so the air will be forced out onlyby the pressure but not by direction?3. Is there any easy workaround for Sketchup that would allow me to create sphere with the required channels along the inner wall to create a fast vortex?I can do screw, nut and bolts, a sphere is no problem either.But I can't seem to find a way to comine both techniques so they work on the inside of a sphere :(Why a sphere you wonder? ;)I like harmony for these things a an egg or a sphere is way more harmonic than a cylinder.On top of that it would allow to create a vortex to my specs instead of chance.Ideally the "threads" would get a smaller pitch with every turn.This forces the airstream to not olny increase in speed (decreasing diameter) but also to be "compressed" before even entering the tube section.The inner stream would pass through a tube inside this sphere, after passing through the tiny gap the upgoing airstream created.My hope is that such a design would allow for the low flow rates of a fridge compressor while being quite small in size as well.Anyone with good ideas or tips?

Options to save on gas while TIG welding ?!?

It's been a while but last weekend I had to some quick TIG welding for a friend with no clue how to use a TIG welder at all.Still wonder why he felt the need to buy one LOLAnyway, the regulator was quite crappy and seemed to only provide next to no gas flow or literally a massive blow from the hand piece.Back home I started to wonder why there is no batter way to direct a smaller volume of gas to keep an inert atmosphere around the welding area.There is a relation between tip position, arc length and nozzle diameter.Obviously the more amp you need the more gas you might need.There are guidlines for the flow rate in regards to the amps used for a reason.And anyone who ever tried to use a TIG welder outside on a windy day knows only too well how costly or annyoing the job might end up to be.A fancy kitchen range hood I saw years ago popped back into my mind.It was a costly designer thing that used directed vortex streams to "suck" away whatever comes from your pots and pans on the oven.Worked surprisingly well and with low noise too.Shouldn't it be possible to make such a design work "in reverse"?A vortex style ceramic nozzle in the hand piece would allow for a much lower flow rate while still providing a strong and concentrated flow of gas right on the welding area.IMHO it should also allow for a much more stable plasma/arc.According to my guestimations a reducion in flow rate of 40-60 should be well in reach - a considerable cost factor...Too bad I can't used my 3D printer for ceramic :(

Vortex tube should have a supersonic nozzle for efficiency; a simple drilled hole will not allow supersonic flow, right?

Scientific American had an article on supersonic nozzles in Amateur Scientist.  The nozzle needs to first narrow and then widen, so that maximum velocity is reached by the expanding air. The Hilsch tube seems to be very primitive because of details like the primitive nozzle.  Perhaps, the Hilsch tube was designed to have too much friction.  Perhaps, the tube was built to be sure it was inefficient and not very useful.  The tube can only violate the Second Law if it is built with a minimum of friction losses.

Designing a working Ranque-hilsch Vortex tube to be 3D printable or machinable on a lathe

I have looked far and wide in the attempt to fully understand how these tubes actually work.Nothing online really satisfies me fully so I made my own theories ;)I won't bother you with them tough as the foucs is on giving some tips on designing these tubes.Lets start with the main components as you find them in petents and some of the online videos and tutorials:1. The tube.It does not seem to do much but it is a very important part of the design.The diameter needs to be correct for the pressure and air flow rate so the up and down vortex can form properly on the inside.The lengh is important as well because you won't the hot end outlet right where the tube is hottest.Too long and you waste more than you use, too short and you won't get a decent temp difference.2. The chamber, rotation box, inlet box or whatever you wanna call the thick bit where the air goes in that holds all parts together.Most designs, even commercial ones, seem to go dirt simple here.Inlet on the side so the air starts spinning around on the inner wall.And that's about it as it really is nothing but a simple cylinder.However, the free space and internal design of the components affect the performance of this chamber.3. The engine, diffusor or cold end tube.This little gadget, in commercail tubes, serves a dual purpose.Firstly I provides small inlets to generate several vortex stream for the tube.Secondly I provides the cold end outlet nozzle.Both the nozzle and the inlets are important for the workings.Depending on their dimensions you need a higher or lower airflow and get a higher or lower temp difference.With just these three bits you see that a lot of variables are involved.I simulated most of my parts, but with the lack of proper software this happened in the empty void between my ears ;)Needless to say I learned a lot of ways to design fance looking tubes with no real function LOLIf you use some aluminium tubing for the actual tube and machined parts you have an advantage over 3D printed plastic parts.Not just in terms of safety but also in terms of actually measuring the temp of the tube.Blessed are those who have a heat vision camera :(Either way, once you start the design there will be a lot of errors you would need address later - and they waste time and material.Let me share my thoughts on how designed my first working tube:Compressor delivers a certain pressure and flow rate.I made something to test how different diameter holes as a substitude for tubes would affect the air pressure and flow.Once I had a diameter that would not drain the compressor and kept a stable pressure I used this to calculate inlet and orifice sizes.Goal was to have the same overall cut area as for what worked on the compressor test.For example if a 10mm hole works fine than a first guesstimate for 5 inlets would be a 2mm diameter.Usually slightly more as interal friction and such create more pressure in the system.So far for the inlets and vortex creating parts - what about clearances??Imagine you have a short cylindrical space where the tube shall be mounted to.Your inlets need to have enough free space to allow for the air to spin around the center.Key is to have the clearance tight enough to keep a high pressure in this area.Imagine the 5 2mm holes from the above example providing the air flow.A 1mm gap would mean insane pressures that most likely will limit performance.On the other side a 8mm gap will cause a massive pressure drop and results in the vortext from the inlets to get chaotic.Hint:If you blow compressed air through the housing with the engine inside but no tube mounted and just a backing plate to close it then you should hear a distinct sound.If it sounds just like air escaping through some holes you got it wrong :(However, if start screaming like mad when the pressure goes up it means you created a quite powerful vortex ;)But don't confuse the sound of small holes with something that almost sounds like a siren ;)A tube lenght of around 15cm seems to work fine for most applications.However it makes sense to check the tube temp to make sure the lenght is set to the hottest part of it.If in doubt, try it out ;)You designed it so well, it makes all the right noises but it won't cool or get hot....I had this problem a lot in my early days.An old patent however gave the clue that you won't find that easy.On the hot end outlet you can use a simple cone to limit what comes out of the tube.Either with fancy internal outlets or just outer casing with slots.Not much different to what you find online.What you might miss though is the diffusor or vortex terminator.You see, the upgoing vortex is extremely fast in it's rotation.If it hits the outlet cone like this then most of the air will be forced out and the inner vortex won't form at all.A star like insert at the end of the tube will cause the outer vortex to become a straight upward stream.Not all of the air will be able to fllow this route, so the rest is refected and creates the inner vortex.A tiny detail that often gets lost it seems.

Is there any free airflow simulation solution available?

I am a bit stuck in a design for a vortex cooling tube and would like to avoid the times and waste of printing new prototypes for minor changes.So far all I could find is either very expensive commercial software or you need to provide all required dimensions and such in text form/calculations.And none of the free options allow for complex, changing shapes along the airflow areas :(It is very time consuming trying to find matching values for diameters, orifices and nozzles if you can only use most basic calculations and testing.When I write the Ible I will include a pic of my pile of not so well working designs LOLThe basic goal is simple: Have a constant pressure through the entire inlet system while getting a nice pressure drop throughout the tube.Too bad a vortex does not care how much you calculate :(For example a drop of inlet pressure that might be minor can cause the entire thing to fail on the cold end.Same story if the air coming from the vortex generator is not moving fast enough.But if there is a too great pressure difference from vortex generator to inlet you won't even get a usable airflow rate through the vortex.No problem getting these things to work just fine with an unlimited supply of air and constant high pressure - different story when using just a 120 liter per minute homedepot compressor...I worked with inserts for the vital bits to allow a drastic reduction of waste for testing but you can only go so far until you need a new body.Is there really no simulation software available for this sort of testing?

Why is almost every free energy video you find a hoax or fake?

The term "free energy" is used both ways by us.What comes from wind, solar or water power is considered free energy.Also everything claiming to produce energy from nothing is considered free energy.Speaking of hoaxes and fakes now is a bit like comparing appels to tomatoes.For me it more like those stage magicians: It all looks real and impossible but they do it, so it must be real.If you really need to brag about your free energy device but are unable to sell a working model to interested people it at least means you are not a scammer.Several people play the game of exposing fakes.And if include this in your search then you get an idea about the amount of fakes or magically illusions out there.The internet is often abused to change opinions or make people do things they usually wouldn't do.Even if it is as simple as clicking on a suggested link for the next video.Patents can disappear or with enough money you can buy them off the inventor.One reason why more and more companies develop in secrecy and without ever applying for any patents - check the swiss army knife ;)There are no conspiracies involving "free energy" but imagine it would be the case...There currently is nothing that would actually allow you to produce enough electricity for your family all year round.At least not if you want to avoid several wind and water turbines and all possible areas covered with solar cells.If you would somehow make a device that produces more output than input (even if it uses up some form of stored energy like magnets) then how would you present it to the world??Could you take the abuse of literally everyone around you calling you a scammer?You know better, so you allow it to be tested - really??Unless you provide all details and open all up you would still be called a scammer.Someone offers you a lot of money to take the thing and have your assurance to never talk about it or invent something similar - suddenly not that impossible to think of...But what if there is no offer but threats instead?A nice show on the internet keeps you safe and allows the sceptics to brag how it is faked.What better way then to make sure there are tons of videos that show similar constructions that clearly can't work? ;)As with every good story there is always a bit of truth somewhere.Over 80 years ago people made magnetmotors that worked.Look it up and check their patents.Most of the fakes we see today are based on the same 4 or 5 machines from back then ;)Our modern life would not be possible without the inventions Tesla made.Still, basically all of his inventions that did not find public use are still considered bogus.How can one of the smartest man of that time have hundrets of used and recognised patents while those using them claim all the rest is useless and fake?Getting energy they can sell was fine.Allowing that everyone can generate all the electricity needed themself not so much.A free generator that everyone can build would never see a meter and you could not force people to put one on either.With unlimited money available those behind electricity, oil, gas and coal will always make sure that anything even just getting close to it will disappear.The internet changed this as now everyone can provide plans, videos and even all required parts if needed.Making someone or something disappear in Africa or Indonesia is easy, doing so with someone who has actual family, a job and lots of friends not so much.Money and contracts are the next best thing then...Remember the hype about Vortex energy a few years back?Videos claiming to have a vortex thingy producing more energy than what is used everywhere.Now in some regions vortex math is actually something people study.And with this the new videos about vortex based free energy devices went down to almost zero.Nothing new anymore that was not shown already.If you study a bit what Tesla did for students and teachers you will find a lot of similarities between his math and the new area of vortex math.But where those vortex guys use our modern math, limited constants and sequences, Tesla actually include all that was known at the time in his math.Like with scientology you have to work your way up the ranks in the vortex world.A lot of things you can only understand by confirming it in experiments, other stuff you will only get know when attending seminars.If you just get together what you find online and try to understand it then try again with a printout of Tesla's circle of math next to it.Knowledge is out there that we just fail to acknowledge or even try to explain if we see it.Just take ancient building skills.We know they did it because their monuments still exist today.But we would utterly fail to replicate this with our modern technology.Let alone with the tools claimed to be available at the time.....Levitation through sound was deemed to be impossible.Then one day we invented powerful ultrasonic speakers and it worked anyway.So how many real "free energy devices" are out there?How knows if it is one, a few or thausands.Same for all the websites and videos out there.After a while you learn how to spot the fakes quickly.Then you still find some videos where you fail to find the hidden battery or motor or power connection.In the end you are left with the same 4 or 5 possible types claimed to have worked almost hundred years ago.Eliminate the bogus and incomplete then there is still some left....It does not mean any of it actually works...That is if you exclude those few companies selling things like magnetmotor generators for a few years now.Going faster than a certain speed would kill you - then we moved on from steam engines.It will never be possible to use the power of the atom to produce electricity - we got nuclear reactors anyway.Now we even try to make fusion generators feasable...So ask yourself if all "free energy" bogus really is just bogus...We know life must exist on other planets outside out solar system but we still could not accept if this life would be more advanced or civilised than we are...Yet we feel the need "to go out there"...Where does Instructables come into play?Take the dare and provide a well documented Instructable that allows anyone to replicate your "free energy device".No solar cells or electric generators please, only stuff that should exist or work.If you don't speak or write english then use some translator and people here will help to properly translate it.The big community here will jump on it, find the hoax behind it and tear it apart.However if they can't then someone will build it to show that it can't actually work.Then imagine the surprise if "I made it!" starts to be clicked more and more...No one could stop the progess or hide it then ;)Of course we all know that nobody will ever post such an Instructable, don't we?Keep in mind that the scam behind "free energy" might just be result of too many scammers...

Unjailbreaking Help

I have a 4th generation ipod touch that is jailbroken. I jailbroke it by using redsnow. Some of the apps cash now so i can't use them, and its a little slower than usual. So, i've decided to unjailbreak it. If I restore it on itunes, will it go back to normal? If I restore it and put on the backed up data, will it include all of the save data on apps, bookmarks on safari, contacts data, and other stuff like that? Do I need to uninstall redsnow from my computer before I restore it? Is there anything that could happen that could possibly make my ipod forever unusable and broken? And does it take a couple hours for it to restore and put on all of the back up data, because I have about 28 gigs of stuff on my ipod? Sorry for all of the questions, but I'm just really concerned that if i try to restore it, something will happen and it will just be a $300 paperweight. Thanks in advance to anyone who can answer these questions.

Does anyone know how to create a fairly realistic flame effect on a dress using fabric?

Hi everyone! :-) I want to go to a fancy dress party as a Fire Goddess, but I'm a little stuck on finding the best way to make a fairly realistic flame effect for my dress. I was thinking of starting with a black sheer mini-dress, then sewing various shades of two-tone organza on in small strips to look like dancing flames, to create a kind of 'flame vortex' effect. I know that's a really bad description, but hopefully this little picture I found might give you a better idea of what I mean: http://2.bp.blogspot.com/_INmNOB9JiHw/SgMoA0oxU8I/AAAAAAAAAOY/PSNiC473-WQ/s1600-h/flame-dress-sketch-lo.jpg I have no idea whether there is a better way to do this, so any suggestions or ideas would be very welcome. :-) Thanks!

Custom Glow Table: need ideas!

Hello everybody! First of all i'd just like to say I just made an account but have been using this site for years and love you guys =] I have this idea for a tv stand / table and I am stuck. attached is a drawing of my table (tried my best). The idea is a table made out of a recycled door as the table top, clear 6'' diameter and 2' long tubes as the legs, a liquid that reacts to blacklight inside the legs of the table such as laundry soap to fill the inside of the legs, and one small waterproof fan in each of the front legs to create a vortex inside the tube. So essentially I want a table with legs made of clear tubes with a glowing tornado in each front leg and a black light mounted under the table to light em' up! I need help figuring out what would be the best / cheapest material to use to create the front legs. Also what type of fan to use that is waterproof and will have enough torque to turn the water. Any help is appreciated!!

Ancient technologies revisited - ancient "levitation" devices

If we look at some of the the ancient monuments we already struggle to come with just one idea how we could recreate it today.A monolith with a weight of close to 300 metric tons is one big thing.You certainly find some creative way of carving it out of solid rock about as hard as granite - even if ou only know bronze tools LOLBut that is archeology these days, always blind on one eye.Anyway, we just assume we carved it out already and somehow even managed to cut the underside off the rock without the 300 tons crushing the tools.No modern fleet of cranes could lift it if you could somehow get them into this remote quarry...And if we somehow would be able to lift it out we would have no clue how to transport it over 400km thorugh sand deserts as one choice, rocky terrain as the second or on water as a last resort with still 100km on land to cover.There is no evidence anywhere to indicate such a big and massive thing was moved from the quarry to the final erection site.....Mainstream experts claim wooden rollers were used - impossible in the terrain.And a boat or float able to carry it on the water would have been to big to fit on the river...Still the monolith made its journey and got erected in place....In other places we find walls and buildings created from single blocks of rock weighing in at around 50 metric tons for the smaller ones...In ancient Aegypt we find similar examples of large and heavy object being carved and moved around like they were made out of thin air.Again texts and other "writings" from sometimes well before our dark ages tell us about gods and people from the sky doing exactly that just by pointing at them and directing them with the hand and arm.Another indicator for this is that some of these huge monolithy rest on foundations made from individual rocks stacked up neatly.Computer simulations could not find any solution to get the monolith onto this base.Unless it would be stright and evenly down....In all other cases the foundation would have been crushed to dust by the weight and only the weight gives it it incredible stability without any mortar and just sand around it.Many theories exists on how these ancient gods were able to do their "magic tricks".Up to and including these gods being aliens or humans who traveled back in time from our own future.None of them though are really specific and prefer to only refer to "technology" instead.So lets take a close look at possible ancient options for levitation technology:How do you levitate a few tons of solid rock?We go small as we have to assume for once, size does not matter here.Practical and theoretical science provides us with a few options.For example by creating a lifting effect based on airflow - like a hovercraft.We know the gods did not create a sandstorm to move things, so that one is out.Next on the list is acoustic levitation.We do this already for fun and some real sience experiments, look it on Duckduckgo got get a liking of it.To make just 5 tons float in an ultrasonic node however would require a sound pressure that would liquify humans in seconds.Apart from the problem of placing and keeping the transducers aligned.Nothing you could do by pointing you hand and waving around...Einstein provided us with the realitve ;) option to simply nullify the mass of our rock.Several options are possible here.For example by making the rock vibrate at the same frequency as our gravimetric field.Sadly we only (so far) accept gravity as a constant force because we can't (yet) understand or theroise properly about what exactly creates gravity.From the same basic formula in Einstein's book comes option two : Eliminate the gravitational influence on the rock.In way too simple terms to allow a better understanding:Imagine the rock is a ball and gravity is an air stream.If the ball is light enough but not too light it seems to float in the airstream.With the right texture on the surface it even spins quite fast and gets even more stable.You could re-direct gravity in a similar fashion to make to rock float.A push with your finger and it keeps moving like it would in the waste emptiness of space.A slightly different theory from a different side uses vortex energy to make the rock float.The beauty behind this particual theroy is that it would actually match the ancient texts quite accurately.Vortex energy is a relatively new field of science and not always accepted, so take it or leave it.Directed energy can create harmonic resonances in solid objects.The idea behind the vortex is that a relatively tiny device is capable to induce this harmonic vibrations.A bit like Star Trek a second energy "beam" can lock onto this specific frequency.By modulating the positive or negavit amplitude you then can move the rock towards the origin of the beam or away from it.Directional changes would happen through just moving the source of the beam, like on a ball joint to keep it too simple.Why would this theory match almost too nicely?A vortex beam could be losely seen as a kind of tractor beam.And the "uneven" movement of these massive objects in ancient texts make it only more plausible.They were not following the terrain like they would have on some antigrav-platform hovering over the ground.Often they were lifted up hundreds of meters before starting to move towards their destination and then they were lowered down vertically.We don't know if there were levitation devices or even anti gravity devices in actual use thausands of years ago.The only thing we know if things were moved without sings of having been moved.And well, that we have no clue how to do it with our modern technology today....

Extreme Futurist Festival 2012

The END OF THE WORLD at www.extremefuturistfestival.com the VORTEX IMMERSION DOME 450 South Bixel Street, Los Angeles, CA 90017 featuring SURVIVAL RESEARCH LABORATORIES show Extreme Futurist Festival is a 2 day arts and technology festival focusing on radical voices of the new evolution. Last year we had a great event and were called "a TED conference for the counterculture" by the LA Weekly. This year we seek to make XFF an even more epic experience. People are going insane over the Mayan calendar hype about the world ending on 12/21/12. This is why we have decided to bring them the apocalypse they deserve. We are throwing an end-of-the-world conference that you will not forget. Children get in free. We will be focusing on cutting edge science and technology along with transgressive performance art and music. Showcasing the most innovative and subversive memetics of our time, we see to highlight an extreme future that breaks the formula of modern culture. The future has been commodified by the mainstream in an effort to make revolutionary technologies easy to digest. As a result we are now living in an era of complacency, in which the true leaders and game changers are made to feel like outsiders. It is time to rise against the dominant current of our society and declare that nothing is too extreme. We refuse to be assimilated into a carbon copied version of a new humanity. As evolutionary agents we will push the boundaries of what it means to transform our species. XFF is organized by Rachel Haywire, Christopher Jannette, and Sean Humphries.

A 15 volt Solar panel powering 12 volt dc bilge pump with no battery. How long will it stay working?

I did a little maker faire project to demonstrate how gravitational vortex power plants work. There was no electrical outlet available so I used a 15 watt solar panel to power a 12 volt 600 gallon per hour bilge pump to keep the demonstration running.  During the maker faire numerous people came between the sun and the panel and the thing stopped and restarted no problem.   I would guess that the bilge pump was running at half strength. (It has a 3 amp fuse so that would mean 36 watts is the max it can do?  An electrical engineer and a computer science student both said that I could probably leave the thing connected day and night and the low evening and morning current would not damage my bilge pump (or the solar panel).  It would just start up whenever the light got bright enough. Would anyone like to confirm that? Also, is there any arrangement with capacitors so that even the morning or evening sun will turn the thing (even if slowly) or is there a way to shunt that weak power to something useful (Like electrolysis of sea or  salty water to make bleach) and then go back to the bilge pump whenever the sun is powerful enough again? I would love to know because the project went really well and more could be done with it. Brian

Web 2.0 Expo Ignite Talk: Budding engineers design, build, and share their rubberband-powered creations on Instructables

On Sunday, April 15th at the Web 2.0 Expo Ignite session, Christy gave a great 5-minute talk titled "K'Nex Guns: Open-Source Hardware on Instructables: Everyone wants open-source hardware, but how do we get there? A group of K'Nex gun-building kids has actually done it on Instructables; I'll explain how." It was fun, people liked it, and she was asked to give it again today during the Wednesday Keynote presentations of the Web 2.0 Expo.In light of tragic events at Virgina Tech, we wanted to reaffirm our message and ensure that no one mistakes it as glorifying violence. The community that has formed around rubberband-powered K'Nex guns is a positive community. They are using their energy to build, document, collaborate, and share their ideas. They help, support, and encourage each other. They innovate on each others designs, and are meticulous about sharing the credit. These are great qualities we respect and encourage. So, we ask you to look beyond the surface and past the rubberband-powered guns to what's beneath. The users' gun fascination will fade with age, but the underlying positive qualities instilled by this community will not. The skills they're building here are exactly those required for a successful engineer, and for a responsible, mature member of the innovation community. We're against violence, but for innovation and design and creativity.One of the chief reasons we started Instructables was because we saw a community growing and thriving around open-source designs for kitesurfing. The K'Nex community is very similar and grew organically, so we wanted to highlight it and share our insight into it. Check out the slides from Christy's talk, here in the attached PDF, and links to some of the things mentioned:The longer user-innovation talk that this talk is based on.KILLERK's K'NEX GUNtoulvus's Making 3d knex models using mlcadmepain's knex tripwire, huge knex crossbow, and XW30K 8-1/2 cm shot ShifleMost Innovative K'nex Gun Design Contestoodalumps's Knex Machine GunTrainman 2000's The VORTEXInnovative Knex Guns groupNo guns K'Nex groupThe K'Nex projects are impressive and inspiring, but Instructables is the platform for for a wide variety of great projects and ideas. Check out some of the other projects on our site: We have other great communities building around bikes, boat building, homemade gifts, micro-controllers, recipes, recycled materials, and many more. Join in, learn something, and share your knowledge with the community. Enjoy your time here on Instructables.Added: Thanks to Fumi Yamazaki for letting me link to her video, which includes a brief hello to her Japanese audience (taken at the end of the conference) then a little bit of my talk

Ancient technologies revisited - being one with nature

Talking about aliens, gods, higher beings and such is almost unavoidable when it come to examples of technology from a time when did not even have the brains to think in the regions required.But we need to find some substitute for the word god and gods.The ancient text provide us with "people from the sky" or "people from the stars".With our modern brains and understanding of advanced technologies we have to think about astronauts and visitors from other planets.It is just the way our brains are wired now.Ancient technology however also includes the most basic technologies and techniques that we either don't know or that got lost through time.I would like to give some examples that show that with a bit of research outside "aliens" people can come up with amasing discoveries.You can find ancient stone walls that look like their individual blocks were cut with a gigantic laser scalpel and then finished with a nice soft rounding.And those "bumps" found on only some of these blocks are said by our archeologists to have been used to place them - but of course they can't provide and answer how they were placed.Experts in their fields analysed the rock and found no evidence of the heat a laser would create.Although they did not consider fempto second lasers...And they also discarded the theory the ancient people used some big bags and "cement" that turned into rock - it is natural rock...However they found several and quick quick ways to dissolve and soften the rock.All with "ingredients" naturally occuring in the area.Like an acedic mud mix that would dissolve the calcium in the rock and even some more aggressive solutions working much quicker.Tests performed indicate it would only take about two weeks to make blocks covered in this slurry to move together with an airtight fit.Once in contact there is no slurry left on the surface and once the fit and surface fiish is satisfactory you just wash the remains off with water...A lot of ancient ruins or even the pyramids show extreme accuracy.Archeologists came with up with a lot of horse manure but never with anything explaining how the ancient builder were able to plan these structures.After all you can just made a crude drawing and get in some case millimeter precision.Especially measuring the height of a big structure was said to be impossible for these simple folks, so they must have had gods or aliens to guide them.Maybe they really provided some home schooling but in reality the task is not that hard.Imagine you would the big pyrmids in Aegypt.You would be god like and only the pharao would be above you.No wonder then that you knew once finished you would find your final resting place inside...Being the smart kid you are you of course properly marked where the center would be and in which direction the sides would face....And you would not just "know" that, you would have a detailed plan to construct it and the required more or less permanent markers on the ground.Like in todays times you would start with the right foundations.So, no matter what you would always have very accurate refence points on the ground through the build process.Means you can quite easy measure the distance from any given point on the ground to where the center of your foundations would be.If you then place someone on the top and center of your current progress you can also measure the distance to that point with the same accuracy.Wives you triangle with a 90° angle....I know you know say I would still need a half decent calculator to use thelengths and angle to come with the height - but do I?a² + b² = c² Sounds familiar from your ancient days in school? ;)You have c and one of the other two, so for example c² - b² would give you a²And my grandfather told me stories about his apprenticship where he used tables ans slide rulers to do math like this.So why wouldn't these ancient builders know these things that are just based on properly understand a circle? ;)Advanced machining skills....Many example on how people in ancient times might have cut through several meters granite exist.Be it ropes with a sand slurry or using discardable wooden slates with heavy weights on them with such a slurry.But when it comes to drilling long and perfect holes the best thing people seem to come up with is again aliens and their advanced tech.You could drill through granite by other means though and still get really nice drill marks....For example by acoustic vibration - a thing te ancient aegypts were good at.Some people liked to demonstrate how acoustic frequency can do impossible things.The measured the resonant frequency of a granit block.In a way that they could create node where the hole was supposed to start.Means you experiment with the transducer until you get a max response at the desired location.Like magic a copper pipe with a supporting slurry and slow rotation started to "drill" into the block.At some point and due to the change of shape and loss of material the node was no longer strong enough for the effect and the frequency had to be adjusted, then the pipe kept drilling a bit further.The resulting marks on the walls of that hole almost perfectly matched the marks of ancient holes, including those on the leftover core bits.If you now say the ancient eagypts had no means to create powerful enough transducer then please check the collecting of oversized "tuning forks" several of our museums have.Some even with strings still attached between the two short ends, some models where several forks are tied together with these very strong cords.Strong after hundreds of years...Many were tested and all had very specific and accurace frequencies with the long end of the pitch fork being at the perfect length for a mac amplitude.Check how ultrasonic horn work for inducers ;)I could continue with many more examples but I think you got the idea here.Not everything we can't explain has to be alien of some highly advanced technology, often it is so dead simple that we just would never consider to look in this direction.A trout appears to be able to be basically motionless in a very fast flowing river.You can see they are able to "rest" as well as their breathing is very slow - no signs of movement, no energy use, how do they do this?A trout does not swim through the water, the water pulls it.Only if the water is not moving or is not moving right towards the trout it has to swim.Clearly indicated when you check show fast they have move to swim down the fast river.They should be able to just float down and only move to keep their heading....In reality however the water constantly tries to turn them around - like this nice directional arrow on your weather station on the roof...A resting fish in a river will always directly face the current and you will never really see them seeking a calm region behind some big rock or such.Put a trout in a tank with no current you will have a hard time seeing it standing still in it....Vortexes, harmonics and geometry are nature.Nature does not like straight lines or shortcuts and certainly has no clue about higher math.Still it is only higher math and computer simulations that allow us to understand a lot of things nature does by design.Maybe our ancient cousins did not get any technological help at all from higher beings.Maybe they were just shown how to use nature and the energies it provides.We are bound to science and math.With that we try to explore and understand things we can only theorise about.If in doubt with particle accelerators....Is there a difference to what we call science and math today to what was the purpose or religion only a few hundred years ago?We try to explain and utilise things for integration that we actually have no real clue about ;)What if the approach is the wrong one?Try to calculat how the next layer of a shell from a snail would look like, how thick it needs to be.You evening would be filled while the snail does not even have enough brain cells to comprehend your problem with it.If math would be based on a true and unbisaed observation of nature and the universe we would have the universal language the bible states we once had ....Our math has fundamental flaws otherwise we would have no problem at all to calculate the vortex structure and behavior of a tornado or water vortex.And of course we would not need a claculator to get from the radius of a circle to its circumfence - we would know as naturally as we know know that 2 times 3 equals 6.It will be subject of another part of this series ;)

How to deal with very hot and cold temperatures when using 3D printed and metal parts?

As the title states...Currently struggling a bit with my cooling tube project.I finally got a prototype that is both usable and printable.And when I thought I can somehow deal with the limited air supply of my compressor I got hit by total parts failure :(The obvious idea beind this old invention is to have one side of the tube freezing cold and the other rather hot.To the problem at hand:1. Resin based glues with activator don't like to bond anymore once you go below zero.And once getting over about 80°C they go soft and fail as well.2. Putty like glue is impossible to apply properly and suffers from simial temp rpoblems unless you go the special purpose route.3. Silicone seems to be the way to to go but it is simply impossible to cure when sealed in with basically no air and moisture reaching the still uncured areas.4. ABS goo as my last result but ABS itself does not provide the properties required to print in the fine details needed :(I am currently experimenting with a PLA blend that has some ABS in it.Chemical welding with Acetone works similar to just ABS.However it goes soft at even lower temps than either ABS or PLA.Possible solutions I still try to avoid:1. Using screws.2. Using threaded connections for the pipe and fittings (just a pain to print).3. Single print for the entire construction.Number three would be still possible on a well calibrated printer but would also mean that there is no easy way for mods, like using a different vortex generator.Right now my desing went down from over 15 parts and the need for well over 20 screws to just 4 printed parts for the generator end and 2 parts for the hot end.Plus of course length of aluminium round tube.But I can't finetune the design to match the tube if my parts constantly blow apart LOLEmbedded printing would work great and result in a properly closed generator end with no need to glue or screw anything.But it is not for the beginner and certainly not the easiest way out for everyone.What I would need:1. Can you recommend a glue that works well with PETG (my prefered option for the final design) while also keeping full bonding strenght between -20 and +100°C ?Preferably with the option to fully cure quickly and in enclosed spaces.2. Is there such a thing like these air hose quick connectors that work with aluminium pipe?I have seen collar like inserts that claim to provide a pressure secure fit but they are permanant things and it is not possible to get the rod out again...3. If you have some easy and simple way to make an airtight connection between a printed part and an aluminium rod then don't keep it to yourself please!!! ;)

Physics puzzle games- Auditorium, World of Goo and Crayon Physics

I really like puzzle games. I've played two that are really addictive and beautifully made, and found another that looks great.AuditoriumAuditorium has a free on line demo. I've played through the levels a few times. The full game hasn't been published yet.The screen has a stream of light particles flowing into it. You have one, or more, buttons that will affect the path of the particles: like one that bends the light stream to the right, or one that pulls it into a vortex. You move the buttons around to steer the stream into boxes that are scattered around the screen. There are many particles in the stream, and by careful placement of the buttons, you can split them into different paths. When you hit the boxes with light particles a new group of instruments join a symphony you hear. The goal is to get all of the instruments playing.Some levels have areas that will change the color of the light particles as they pass. Some of the music boxes are different colors, and you will have to route the light particles through the color changer before you send them it into the box. Try it out, the free online demo will make it very clear. I didn't even look at the directions. It's easy to find your way as you go. I love a game like that.PlayAuditorium.comWorld of GooIn World of Goo, you have to stick living gooey balls together to make lattice and build some kind of structure (tower, bridge, rope, ...) that allows the gooey balls to reach the end of a pipe that sucks them up. The Gooey structures are not stiff. If you don't build your structure carefully it will bend and can collapse under its own weight. It is a 2D game with a comic book style to the graphics. There is also a level designer and an online community where you can share new levels. I haven't experimented with these yet - I'm still working through the levels that came with the game.There is a downloadable demo for both PC and Mac. There is also a WII version for sale.It is drawn and designed beautifully. Totally addictive.2dboy.comCrayon PhysicsI haven't played this yet but it looks really great.The graphics look like they were drawn by a 5 year old with a box of crayons. When you get to a level, it presents a drawn scene with a star and a ball (it's actually an apple. Must be a tribute to Newton) somewhere in it. You have to draw some kind of mechanism, or ramp, or some objects, or... As you are drawing, the objects develop mass.Everything you draw then reacts with gravity. You have to harness the momentum you get from everything dropping to the ground in order to push, throw, drop or guide the ball so it hits the star.Look at the video it is self explanatory.

Letter from the Editor: The Perfect Gift

Is it just me, or does it seem like time speeds up around the holidays? It doesn’t matter where I’ve been in life, time seems to enter a sucking vortex towards the end of the year. Every year I have plans to be more clever, more efficient, more thoughtful when it comes to the holidays, and each year I hear myself getting snappier and more impatient with the demands made upon me. “A Christmas list? I don’t have time to think about what you could give me to make my life easier!” That’s right, I’m an ungrateful troll. So in an attempt to keep this holiday-troll at bay, I make lists. I gather supplies. I get excited about what I can make for friends and family, and I set out to learn whole new skill sets to accomplish my goals. This year, a laser-etched arduino-powered cribbage board with hand-carved pegs! Knit socks in decadent colorways for everyone in the family! Infused liqueurs with home-grown fruits and herbs! But let’s face it, last year, I taught myself crochet so I could make a friend a beautiful sampler afghan. It’s almost done! It’s right next to half a sock I started knitting the year before. Oh, and I don’t grow fruit. Still, every year I pride myself in how this year I will make simple gifts for family and friends. I will eschew consumerism! I will not fall prey to deep discounts and crowded malls. I will not find myself waiting by door to accept delivery. And yet, come December 24, you’re likely to find me trying to hide my face in the endless queue at whatever store is still open at midnight, arms rammed full of manufactured goods that no one really needs or will remember, promising myself that next year I will start in May! Let’s get real. I didn’t start in May. I will probably never start in May. But maybe one day, I will learn how to think mindfully about the holidays and what they mean to me. I will think about my loved ones and what they mean to me. I will simplify and know that it is enough. I will learn that it is for the best of everyone that I find time to breathe and to let go. One thing no one wants for the holidays is a cranky troll – I have at least learned that. To be honest, I don’t remember the gifts I receive from year to year. What I remember is the time I get to spend with friends and family. So this year I will try to make myself a simple gift: the gift of time. Time away from a computer, away from responsibility, away from my self-imposed pressures. Time to spend with my loved ones. After all, isn’t that the best gift we can give? Ok, I’m still going to make something for everyone I can. I mean, c’mon, it’s what I do! But reflecting on this helps me remember the point. So how do you handle the holidays?

Repulsine - the great mystery...

Even before the repulsine saw some attention during WW2 there were sightings of what we know call the classic UFO shape.Be it in Austria, Poland or other places in Europe, people reported weird disk like thing with a dome flying around.What leaked in images and documents after the war shoed that the repulsine looked basically identical to what people saw as a UFO in the sky over big parts of Europe.Then again, the repulsine appearently never made it a usable stage, same for most jet fighters at the time and still they flew around...If we now just take it for granted that actual test flights really happened back then you might wonder why we did not see any after the war anymore.For most critics it is a simple sign of facts and "confirms" that the replusine might have been a nice idea but never anything that really left the ground.As said, I often like to dig deeper and in this case the digging took far more years than what I planned on.I can not provide any solid proof for the following but I am sure even a sceptic will come to similar conclusions after reading it.Try to find some "eye witness" reports from people who saw the so called "Roswell UFO".Yes the one that made Area51 so secret and famous...Reports can be boiled down to some essential features of the hull, for those who saw it proof that it is alien.Three distinct round shpes on the underside, like you add the bottom of an egg to a round disk.Said disc of the bottom was also shaped like a wing, or the flying disk toys our kids like to play with.On the other side the shape grew up like a half shphere with an added cone or round top on it.On these area they claimed to have see engine outlets or similar and appearently the top cone was spinning in another direction than the rest of the UFO.Now I am no expert for Roswell but if I leave area and time out then I could have been fooled to think these people discribed exactly the same thing people saw a few year eariel flying over Europe.The Roswell UFO was not from another world, just stolen from the looser of a really bad war.What was seen was a working Repulsine, be it an original or something the US created from the 5 prototypes that disappeared after the war.Ha, ha, good one, then why don't we saw them flying after this anymore?Well, for starters it was a testflight gone wrong.Presumable it was planned to be limited to Area51 but the pilot lost control.Considering the Nazies appearently did their best to kill everyone involved in the project before the aliies arrived it is no big surprise.What that test flight would have shown is the impossible manouvers people already witnessed over Europe.90° or more turns at full speed instead of making a turn like a plane, sudden changes in alitude as well as accelleration on a level that makes even modern rockets blush.And if it really was the first bigger testflight they did it explains the big secrecy about the Roswell incident and what followed and created Area51 as we knew it.A "weapon" capable of these things would mean total dominance and options to impove planes and more.So why did they not even do that - or did they?The repulsine was created based on what we call today fringe- or pseudo- sience.If there is only one peroson, or a few that can even understand the claimed working principles that it can't be science as we know it.So, lets take a look what things were already heavily used in the repulsine that "we" claim to have developed or discovered decades later.Coanda effect.When air travels over a surface then it will follow the surface.You can try this with paper strips and blowing on them as well as a stream of water and some shaped objects.Long known but never found any real use until the military picked it up.For example air inlets were then developed to utilise the coanda effect.Remember how a lot of them these days look like a ducted fan housing?The round and slightly conical shape of the inlet will actually act like an airfoil and provide lift - of pulls forward in the direction of the air flow direction of the engine.I supercars we use it to create more downforce and better aerodynamics.Venturi effect.Again a very old one but funny enough also a major factor to make a jet engine work.Tesla turbine.In the Repulsine the rotating copper disks acted like a huge Tesla turbine by using a similar effect.The space between the disks got smaller and smaller towards the outer perimiter.Due to the fast rotation the molecules were accelerated and this created a partial vacuum.We use these principles today for specail vacuum pumps but also in military applications.Harmonics.Without harmonics and resonance the Repulsine would have been impossible.And at a first glance it seems we never made any use from that bit of the machine.Then why do we design exhaust systems in such a way than already the extractors ensure a pump like action and controlled backflow?The sound a good exhaust makes is also based on using the harmonics created by the explosions in the cylinders and expanding gasses.We learned that it is far more efficient to use harmonics and resonance in an exhaust system from somehwere ;)Plasma.The repulsine was said to have emitted a bright glow during certain movements or speeds.To create plasma we need a lot of energy, not so much however if the plasma is a by-product anyways.We learned that a high enough voltage differencial in a vacuum can create a nice plasma arc.From there things like analog TV monitors were created.But we never made anything that creates plasma for any use in an atmosphere.Well, unless you start to check supersonic rocket engines and other things.The working principle is very, very close here in some applications like the ramjet.Vortex energy.Today we see all vortex energy stuff as a free energy scam or at best a waste of time.But from the inlet to the outlet the entire Repulsine utilised what we now know as vortex energy, vortex math and so on.The air is twisted and spun around so many times that it is hard to keep track - but it always happened in a harmonic and resonant fashion.In some way this is implepemented in very expensive cars to keep the ventilation system almost silent even at full power.If you ever take an expensive car apart you might wonder why the air system is not as smooth and straight as you would have expected to get this silence ;)There is more but the list would become too long ;)So, if the repulsine was really that great then why was it taken apart to only utilise fractions of it in other things?If you have something really great that combines a lot of things then no one would suspect if you "developed or discovered" some of it in other projects.And to give you a very bad comparison for the other way around:If you know how to combine a petrol engine with some long blades then you could fly!I know, we did that already but you get the point.I can give you a motor and blades but that would not mean you could build a plane or even helicopter!At that time and still today something like a Repulsine would upset the "balance of power".If claims are correct then the engines of the repulsine were only required to provide the enrgy for directional changes or speed but it flew on "free energy" as the main engine system.In lame words like a jumbo jet that only needs a small engine for the hydraulics and electricity...Another big problem is the replication even if you would have a complete and working model to disect.You see most parts were brazed or welded as screw or rivets would have been problematic in certain areas.Other parts like the Kudo horn like intake systems would even today pose a challenge if you want to replicate them 100% correct.And if your understanding of science and physics greatly differs from those who originally created the thing...If your understanding tells you a dice has 6 sides (we all know that) but in my understanding it would have 16 then you would never understand how my dice rolls ;)Bringing true free energy of any form into this world is only allowed if someone can still make good money from it.Just check solar cells and wind generators - we all can have them but our providers make sure they have enough of them as well ;)Will we ever see a fully working Repulsine again?Of course !Some people like old cars, some collect old planes or old machines and tools.A great project for people in the right trades is always to build thier own little steam engine.So to say as a reminder of how it all started.Same will happen with the Repulsine as the first really utilised free energy machine the world had.The war and killings were not what really scared the world.This happened and will happen over and over again to various extends.Really scary was once certain people realised what might happen if over there the war would end with a victory and people would have time to develop for peaceful things instead.Without the war or this idiot Hitler a peaceful war would have taken over the world by storm.Those making sure we know nothing else but paying for our fuel and energy would have lost their monoply.Times change though...We destroyed our world with our needs for fossil fuels and electricity.What is left we destroy by chopping it down, digging it out or just by building new estates on prime farm land.People are now more desperate then ever to find ways to reduce their energy bills or enviromental impact.Otherwise Google wouldn't make billions on all the fake free energy videos out there.But what would it take to recreate the Repulsine?The person able to come up with the understanding of at least attempting to build one again would need to have certain qualifications and titles.He or she would hold a Nodel price for completing some of our known laws of physics or for finding some of the still missing ones.It would be a quite hard to understand and like person too, maybe even highly autistic.The person would also have an addiction like need to complete things, add the missing bits.And of course a totallydifferent understanding on how nature and the universe work.David T. from England is such a person, or at least the closest mankind can offer so far.He can see math in his head as shapes and images.Complex math problems appear to him like developing landscapes in high detail.He even learned to speak icelandic fluently within 7 days!!Imagine such a person would develop an interest in the old pioneers like Schuberger, Newman, Tesla and so on?Where we normal people fail to see any relevance or connection a guy like David would be able to literally see how all these inventions and ideas connect.He would be able to SEE the math behind it!Knowing how something was supposed to work and combining what is known through patents, drawing, videos or reports would enable such a person to make conclusions.For example where we might just see a nice pattern when we throw a stone into an undsturbed lake such a person would also already know and see the corresponding math the created the waves and why they were created exactly like this.Assuming David has no real interest in such things, then is it possible others already try?Sadly yes and even worse they do it with kids.Learning methods that are different can bring great results.For example while we use a calculator for big numbers some kids attend really strict and performance based classes to do this with an ancient abacus!After years of hard and often painful training they are able to it with a small abacus that only has a single row of discs.Shortly after they graduate to a virtual abacus - they only twitch their fingers in the same motions they would use on the real thing, but the disks and rods are all just visualised in their heads.That however is all meant as an improvement and the kids do it because they want to and not because they are forced to.Like learning to be a chess champion before even being old enough to work...In china however we have a very selective education program.Kids are not just trained slightly different to our kids but also closely monitored on their progress.As soon as one stands out for some skill it is subject to examination.Being well above average here means it is an opportunity for the kid and the parents - on paper at least.We in the western world would see it as a viscious circle though.Over the years china developed not only a better understanding of how these special kids brains actuall do their things but also how to create tests for this purpose.What looks like impossible or nonsense to most kids will trigger a scecific response and understand in those that are special.We would create something that allows parents to know early on where the kid has really good skills and what activities should be promoted.In china though the parents receive a nicer flat or some additional income while kids are send to a far away school.Again we would refer to such a school more as a boot camp.Discipline is at least on military levels, same is the punishment system.In most cases families are not reunited for many years, phone or even video calls only happen in the rare times when western TV crews are allowed a sneak peak.I just say: If a kid would see the parents often enough then it would not only know what to talk about but also be happy to talk to them - this however you won't see.It is like they talk to some distant uncle or such.What is really scary though is how these kids are trained to see their purpose and how important it is to be the best in what they do.Imagine you lost your kid at an early age and the only thing you got over the year was letters from the government saying how well it is doing and that you can be proud of it.Then it graduates and you are not even allowed to be there on that day...After that the kid is gone for good, you get a new flat and your proud kid supports you with some nice extra income.You don't get to know where it is working, what it is doing or if it might just be attending some university.By any standards these graduated kids can be seen as a great number of genius young people.Math, music, languages, science, you name it and they will have the experts aged below 20 for it.But what do they do once school is finnished and life starts?So far no reporter or family was able to figure it out.Means they don't appear in some high profile company, they don't start a successful business or teach at any public or private school.I leave it up to your imagination where thausands of kids find secret employment once they graduated....If, at least in theory we could be able to understand all these old technologies then why don't we at least try?Everyone has a goal, some desire a happy family and nice house, other need fame or just money to be happy.With that comes greed.You might have a really nice car but that does not mean you would give to some neighbour for a trip.Even if it just a nice rose garden, you might not want to share the views with anyone.This is true on all levels and we created a term for it "Need to know basis".If you just operate a press in a factory then you don't need to know when or what the next job is that comes for your press.You will know when it arrives and can check the documents attached.You don't need to know that your council is expanding and it is only seen as a courtesy to let you know on some notice board or in the local newspaper.And even our government does the same.What we do from the first days of our new baby we do on all other levels in the same way.What the baby does not need to know we won't tell or show.But we provide all the littly anklebiter needs to develop and be happy.Changing nappies, feeding, proving comfort when sick or having a nightmare.Later we teach language and other skills like walking.It goes on as you know...Humanity as a whole is like a little kid as well.If we would know all the little, dirty secrets then we would riot and go mad.Things that are of no concern are nothing we need to worry about, so we don't get to know them either.Knowing how build the latest fighter jets is seen as a thing that would give a possible enemy an advantage.Makes a lot of sense to everyone as these things might have to protect us one day.The questions that remain are:If humainty is a child, then how old are we now or when do we graduate?If there is a collection of secret and old knowledge then who owns and controls it?What would it take to force the release of all the things people actually created for a better world and not to be locked away?As funny as it might sound but one answer to all these questions would be to do nice orund trip in your Repulsine.Fly over ever single country in this world.Let their guided missle and what not chase you and once enough show then how quickly you can make a 180° turn to get behind them.So called unimportant countries might ignore you and the people only enjoy a nice show.Those powerful enough will fear you and think it was "the other side" showing their superiority.Once done with your round they all will have to realise there is a new power that is at the helm now: Knowledge and understanding.No more secrets, a repulsine for everyone who wants the plans to build one.A new world would start.Ever thought about that when wondering why all these "Aliens" we see in their ships in our skies never land to say hello ? ;)Even if they would be Aliens and not just some human pilot in some experimental craft:Shouldn't this demonstration of absolute power and control without any violence tell us something?The Repulsine need to come back to life to end all this UFO nonsense and Alien theories out there.You hear the sounds, see the ligh show and impossible abilities.And suddenly most if not all UFO sightings would have a common factor again.Just because the Repulsine is claimed to be lost and that it never actually worked despite film evidence showing the opposite does not mean there is no one using the technology.A working Repulsine available to everyone would also kill the doubt on so many other old inventors and "fringe" scientists.Science and physics would need to be redifined as would be able to find a lot of missing links.I know there is not only a lot of people out there trying to get what they can about the Repulsine but also that there are others who try to prevent this.You have a really easy time getting permission examine some old and histrically important artefact from a museum than getting just a hands on approch for what remains of the Repulsine in various places.Not even decent 3D scans will be allowed.Anything like just getting a tiny pipe cam inside is rejected with the excuse it could cause damage.If the thing is a hoax and never worked then why would it be so important to never touch or move it? ;)I recently got word that two of the remaining Repulsine "artefacts" were examined by the same group of "scientists".This happened in the late 80's and said scientists were claimed to have had acces to a collection of spare parts for the original Repulsine that was lost after the war.A private collector was also mentioned who denied all access but what he had in a secure storage facility appearently disappeared shortly after his refusal.Putting all the dots and hints together it would mean that someone in the late 80's was able to get literally everything that is left of the project in his hands.Those who claimed to have seen these scientists working on the Repulsine leftovers claim they used top notch technology to do so, including 3D scanners - and those were basically imossible to get back then for any uni out there...The laptops used were said to use touchscreens and were connected to all sorts of equippment.And they did it in almost total silence, like a group who studied a performance many times and knew exactly what do when and where without the need of many words.Professional in examining something unknown all all possible levels.I was unable to get any information on these scientist or who they worked for.But if you are one of them and readin this then I would love to hear from you!
