I am in Australia and I wish to wire in an exhaust fan to my fluro light operated by the one switch. Answered

The switch has a red wire and a white wire leading to the fluro light. The fluro has twin and earth (red, black and green) leading from a previous light in another room and another exiting to the next light in the house. The fan has two wires, a brown and a blue. I attempted to parallel the wiring by connecting the blue to red and brown to white. Once the fuse was turned on, the fan operated automatically and the light flickered without the switch being turned on. I reversed the wiring (brown to red and blue to white) with the same result. Logic failed me. Given that it is two wires on the fan (pos and neg I assume) I figure I am better parelleling to one of the twin and earths, but which one? Electricians charge a minimum of $240 per hour here, with a minimum of 1 hour charge, regardless of it being a 2 minute job. All connections are 240V. Wire joins will be completed using BP connectors.

Got any tips on replacing an exhaust flex pipe? Answered

So, the flex pipe on my good old Mercury Mystique is almost fully cracked on one end.  The place where the flex pipe and braiding are connected to the solid exhaust pipe is only about 25% intact.  The result is that my car sounds like a hot rod when it's running, has about as much power as a scooter, and is likely leaking carbon monoxide and other nastiness into the cabin. Obviously, this needs to be fixed. Normally, I'd take my car to an exhaust shop to have it fixed.  This time, I have neither the cash (likely at least $600, but probably more like $800) nor the inclination (spend 800 bucks on a car that would sell for 500? no thanks!) to have a pro fix it for me.  So, I want to do it myself. I've already purchased the proper length of flex pipe with the intention of grafting it in.  I have a saw to cut out the old pipe, ramps to get under the car, and flux-core wire welder.  So, mechanically-inclined friends, have you got any tips for me?  Can I weld in the new pipe while everything is attached to the car, or do I have to remove the exhaust system and weld in the new flex pipe on the bench? Can I save myself the hassle of welding the pipe and simply clamp it in place?

How build a cost-effective device that automatically clears exhaust fumes out my garage?

Soon I'm going to move into a building which shares living quarters with a garage. I'd like to rig up some sort of relay-triggering device that opens a nicely sealed set of vents (one intake, one output) and activates a fan exhausting garage air  - one that activates the minute I open the garage door, and then continues exhausting fumes for a few minutes after I drive the car away (and close the garage door). After those couple of minutes, the fan would stop, and the vents seal shut Due to the "lay of the land" (garage right off a busy road, with very short hidden driveway) I will be backing the car in, so exhaust gases will be concentrated at the back of the garage (close to living areas) - rather than near the open garage door. And as my car has a turbocharger, I often need to let it idle for a minute or two ( to let the turbo cool down) before turning it off to park. So it would be most useful to be expelling those exhaust fumes out of the garage! The question is - what's really the most simple and cost-effective platform for this kind of a system? Could a 555 timer, a few discrete components and some relays do the job elegantly? Or am I better off just diving into Arduino-Land?? Any related ideas (solenoid-closed vents, efficient fans, ducting through walls, etc ) that are especially thrifty - would also be greatly appreciated!!!

Wiring up a bathroom exhaust fan-how to?

so I cut a nice round hole in the ceiling of my bathroom. physically installed the fan. was going to wire into the light so that the light switch would turn on the light and fan in one. the exhaust fan has a plug- 2 prongs (i'm in australia). the wiring to the light switch is only 2 wires. the light wire was exposed /available half way between the light socket and the switch. so thought that would be a good place to cut the wires (mains power off and fuses removed) thought at first I would wire the fan in serial and that didn't work. tried parallel and htat didn't work. I was going to wire a "power socket" on  to the cable.  the fan has a cable coming out of it with a plug . inside the power socketty thing there places to out the wires. and then turn a screw to keep them in place (ooooohhhh , the technology talk is a flowing). so black has one socket thing to place wires in and red has 2 socket things to put wires in. so how (and please use a diagram if it makes it easier for me) do  I wire the bastard in to work??? I've tried every combination - except using red wires in to both red wires places with turn screws in the socket thing.

I have 3 devices under my car connected to my exhaust, but I dont know what they are or what to do about them?

I have 3 devices under my car connected to the exhaust system. Im unsure about what they are, what I can do about them, or how I can modify these to make the car louder,lighter,and less restricted. The car is not broken and doesnt need repair, this is about modding it. My biggest concern is the last device (3rd picture), because it is big, and most likely heavy. I know the exhaust system will restrict the engine, I also know that the exhaust system has a muffler and a catalytic converter. So my question is   What is this device in the back? How can it be removed/bypassed/replaced/modified to be louder lighter and less restricting? And if I cant do anything with it, what can I do? (the devices are in order from closest to engine to farthest)

50cc 2 Stroke Tuning? Answered

I have an old moped that I got for cheap and I am trying to fix it up. I replaced the carburetor and the new one is a little bigger even though it is off of another 50cc. It insisted on running extremely lean, but I was able to get the fuel/air mix balanced by putting some foil tape over part of the intake to get more vacuum behind it. It will only run right if the exhaust is on so that it is not lined up perfectly with the exhaust port on the cylinder. If the exhaust is taken off it will start first kick, but if it is lined up the way it should be it will not start. I took it off today and when I put it back on as close to the way it was before it would start but is now running very lean, beyond what I can tune out with the carburetor. If I give it full throttle it bogs and has no power, but it has fair power at 1/3 to 1/2 throttle. It also is getting really hot and has absolutely no power once it gets very hot. Yesterday I hat it all just right and it ran with none of these problems except that full throttle was still not where it got full power. Does any one have any ideas about what I have to do to make it run right? Maybe there is no option but careful misalignment of the muffler? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- It turns out that the problems were that the muffler was clogged, and that it was running too lean at first, but too rich once it warmed up. Thank you for you suggestions.

HHO and you!

Ok, so hho has become the new fad in the mpg race, but is it really effective?  Conservation of energy dictates that the energy required to separate water in to its base components is equal or greater to the energy released during its reconstitution.  The key to making HHO a viable source of additional fuel would be utilizing the waste heat from the engine to provide the electricity needed. TEG's + exhaust manifold + water = ? Discuss!

Pre-purchase questions of a petrol-driven electrical generator - cos you guys know best! Thanks!

I have a caravan in a remote location and I've got round to thinking of buying a petrol-driven electrical generator. I'm figuring on using this with an ethanol (E85) fuel. I'd really appreciate some help if you can to any parts of my queries. I have looked around on Google for advice but there's a lot of conflicting stuff as usual and I know you guys are good. My normal max load is around 4,500watts but I have security HID lights which have a huge inductive start for a few millseconds - how will a suitably rated generator cope? Do I always add a 20% margin to the generator capacity so for a 4.5kW load I should get a 6kW machine? Or is it not 20%? Given that the machine will be outside, I don't want to annoy the other caravanners, so if I build a sound-proofing box with just an outlet for the exhaust, could I expect the noise to be reduced signifcantly, given a lot of noise will be coming from the exhaust itself? The machine has a tank of 15litres but I want to increase this safely - how could this be done, if at all? Safety is paramount (naturally) but then so is convenience. Do you have a generator? If so, what do you wish you knew beforehand or any regrets? What kind of maintenance schedule is there and is there a performace improvement for modding the air-intake to a larger filter like for cars and bikes? Many thanks for reading my question and thanks for your time to reply.

HHO generator improves fuel efficiency of petrol engine!

Reproduced verbatim from The Fortean Times issue 249, republishing from FT35JUNE 1979On the 15th a demonstration of a "revolutionary" energy device took place at an undisclosed location in the UK. Iowerth Thomas, 58 a Welsh inventor, hoped to interest both government energy officials and an Arab consortium. Mr Thomas had been experimenting since 1936 with ways to make petrol engines burn more efficiently. His "bolt-on" device promised between 25 and 40 per cent efficiency using "the electrolysis of tap water", plus a cleaner exhaust. The government scientists' response - that it was impossible - spurred Mr Thomas to demonstrate it for them. He reported to the motoring correspondent of the Daily Telegraph that his stationary engine ran for 112 seconds with his device and for 77 seconds on the same amount of petrol without it. The usual objection to electrolytic systems is that the energy needed to run them is greater than that produced. With some sarcasm, New Scientist sniffed that the device needed to be much smaller than the room-size contraption Jones used. What really stoked their scorn was Thomas's reply when asked how it worked: "It's beyond me," he said. That was the last we heard of him and his promising device.How has this technology improved in the last 30 years?L

Forge Ventilation help?

Hi all, Due to location & noise, in order to continue using my coke forge and anvil I must move indoors, into the shed to be precise. I know it sounds a bit crazy attempting to run a coke forge in quite a confined (10-14 m3), fairly air tight space, but I have researched thoroughly the dangers and safe working levels etc and have the use of a fully calibrated gas analyser designed to measure CO in real time, so safe operation will be measured to the nearest ppm :)  The fans gumf claims 1060 m3/hr which I guess is best case, flat out @ 50hz and obviously does not allow for any other mechanical losses, but even a conservative estimate must give around 45 air changes an hour, which to me sounds like more than adequate clean air coming in to displace combustion gasses. But I guess the first question is will the chimney work as a passive exhaust,  to maintain positive pressure behind the chimney (which will be 12") I will have only a forced air inlet and no other vents other than the chimney itself, trouble is I can see it both working and not working: 1. Inside air will be forced up the chimney as that is the only way out = more ventilation 2.Inside air will cool the air in the chimney reducing the natural draw =  less ventilation And even if the CO issue is overcome will heat just ruin my plans anyway?

Nissan Sentra How to disable Spark and Fuel injection on one cylinder? Answered

2002 Nissan Sentra GXE 1.8 liter engine. How to disable Spark and Fuel injection to one cylinder? Explanation. This car has been losing small amounts of Anti Freeze. I thought it was leaking into the Oil from the Head Gasket. Oil looked a little milky to me. Had a mechanic check it out and he believes it is leaking into the cylinder chamber. He said he didn’t see any water in the oil. Some white smoke is coming from the exhaust, but not too much. Hopefully I have caught it before it gets too bad. Since this car has 175,000 miles, it would be too expensive to just replace the head gasket. As an alternative, I’m going to try K&W; Head Gasket and Block Treatment. I have read where this will work in most circumstances if you follow the instruction to the letter. In the instruction it says to check the spark plugs for an Orange/White crystal or fluid appearance. I assume the idea to remove the spark plug is so the pressure from the cylinder compression will not force the treatment back and not allow it to really seal correctly. But how do you disable the Spark and Fuel injection on one cylinder? Any help or experience would be helpful.

Why don't superchargers and turbochargers break the laws of physics and HHO generators do? Answered

I saw an article today on how HHO generators are just a scam.  There are of course many scams associated with it, but I have yet to test the whole thing myself so I have yet to form a solid opinion on the whole thing.  One of the biggest arguments is that based on the laws of thermodynamics, the same energy is required to split the water as is released when they recombine.  This is true, but couldn't there be other benefits to the whole thing which are being ignored.  If that statement was true wouldn't eco-boost engines be a scam.  The turbocharger can't just create energy can it.  The exhaust which spins up the turbo causes back pressure on the engine right. Then there are friction and slip as well.  It seems very lossy right, but it works. It isn't a scam.  The same goes for a supercharger, the same energy of the added compressed air is taken from the engines drive train.  Now I understand that the compressed air causes a better burn similar to mixing KNO3 with sugar vs just burning it in plain air.  But what if you mix gunpowder and sugar, why is that any different.  I feel like this analogy accurately displays what is going on in both cases, and I feel like there could be an argument for the benefits of HHO. Again I have no experience in the subject yet, but it all seems reasonable. The HHO isn't being used as a fuel, it is being used as a booster which pulls more energy, more efficiently from the petrol.

Idling/stalling problems on 1986 Ford F150

I'm driving my brother's 1986 Ford F150 4.9 V6.  It sat, unused, for about a year before I started usuing it, and he didn't perform any maintanence.  Got it running in February and the biggest issue was (and still is) the carburetor.  It's functional, but only barely (apparently there was some bolts missing on the breather that weighed it down and stripped some of the bolts on the carburetor).  I took it in to the shop, and they did what they could without actually changing out the carburetor (I don't have the money to buy a new one, still).   I was told by the mechanic to idle the engine for up to five minutes, depending on the weather, to warm the engine. It's been working okay, as best as can be, but no huge problems. But then the heat riser on the exhaust manifold broke off on Thursday (I borught it back to them to look at, they said the whole manifold would have to be replaced and it'd take 4-5 hours).  Again, broke, so can't afford the $500+ they quoted, though they said it'd noisy but okay to drive until then.  Then, starting about two days ago, the idling got kind of clunky and it will sometimes stall out if I'm stopped or idling for more than a minute or so.  When I'm driving, it's okay, but slowing or stopping it can idle (I know keep one foot on the brakes and the other periodically tapping the gas). I really don't want to go back to those mechanics again (I get the impression that they're taking advantage of me being a girl), and if there's something I can do myself, I'd like to.  If there's suggestions or input of any sort, I'd greatly appreciate it.

i'm making a boiler can i use a one way valve? Answered

So i'm trying to make a boiler system so that i can get a little bit of energy back from my forge the idea for the forge is to basically cut open a 55 gallon drum on the bottom flat side and put a forced air pipe in the small orifice normally used as an air hole when dumping the barrel. then i'd cut out the space needed to fit 4 inch stove piping where the larger 2 inch orifice is and carry the exhaust outside and out of mind. then i'd cut a hole in the bottom of the barrel so i can get my work in, put in a steel plate that was cannibalized and drill a few air holes in it, put refractory cement everywhere and bob's your uncle. what i want to do however is to put some water pipe in the fire box and have it turn a turbine or something, i'll cross that particular bridge when i get to it. but the main question is how can i safely store a reservoir of water so that the pipes don't run out of water halfway through a burn cycle? the thought was that i'd invert another 55 gallon barrel and connect it to one end of the pipes with a one way valve. the only question is would the valve guard the second barrel from the pressure generated while still allowing the water to flow in when necessary? or would the barrel just load up with pressure and when i hit 20 psi it just explodes in a hot watery mess? any knowledge about this would be great, stuff like where to get cheap but good pipe in upstate new york, where to get regulators, how to find the valve itself, or even where i can find safety fittings like pressure release valves and temperature control.

What do I need to make laptop stand cooler?

I would like to make my own custom laptop stand cooler with fan (6 fan) of 8 or 9cm The reason why I need it that many is because my laptop gets overheat quickly & sometimes it shuts down by itself. Ps: I would like to connect the fans to wallplug with adapter or usb wall plug adapter. 1. I would like to know what do I need besides 6 fan, mdf / acrilyc for the stand, adapter, usb cable? 2. For this project, which fan is the best for me, 2 pins, 3 pins or 4 pins? 3. Moreover, which voltage should I have a look and which 1 is better: high rpm or cfm flow? Thanks Edit 1: Sorry as Im complitely blind with electricity, I will have to ask lots of questions. Hp already acknowledge the problem but cannot do anything with the overheating other than suggesting using external fan & at this moment im using deskfan to blow the exhaust hole of the laptop. So this is for example the fan that I found on eBay Voltage, 12V. Voltage range, 6 to 13.8V. Current, 0.20Amps. Speed, 4500RPM at rated voltage and zero pressure. Flow (max), 67CFM. Pressure Rise (Max), 0.3inH2O. Thanks again for all the answer Edit 2: To make it easy, this is my question 1. Id like to put 5 fans with above spec, does that mean I need power adaptor that can handle 1A (5x0.20A) ? 2. Would it be better if I use power adaptor 2000mA or better to stick with 1000mA ? 3. Im planning to use dc connector head (see pict) but I only see 2 cable holes. If the fan has 3 or 4 cables, which cable should be put in the minus hole and which one in the plus hole, and what to do with the rest of the cable(s) ? 4. Would this power adaptor perfect for my project? Sorry again with this dummy questions, but like I said Im complitely blind with electricity. Thanks for all the answer

Project VR6

Hello all, thought id share my progress of my 97' VW Golf mk3 VR6 2.8 to create some discussion and VAG banter. I brought her completly standard and wanted to build a real sleeper for road use and track use that is fast, practical for everyday use and safe for the family. When I got her back in 2009 she was a standard vr6 nothing really special just a well looked after example Firstly I gave her a good clean inside and out along with a service.......and by clean i mean really cleaning, shampoo the carpet, treat the leather, clean out the heater units, remove and shampoo the roof lining, polish and resin the paint, de greese and steam clean the engine bay to name some of the bits ive done. The result was a very clean base "template" Once all was clean and I could see areas for imporvement I began the work, replacing all the bushes, front and rear lower arms, brake lines, discs, calipers, exhaust were the easy steps When it came to the engine itself I did not want to mess about with it too much just improve the BHP and general running of the car as 174bhp from a 2.8 VR6 is shocking. So removed the engine and re conditioned the gearbox and clutch. While this was out I thought it best to also do the pull chain not a big job but much easier with everything out, once back in I still was not finished.... After giving the engine a full service with new plugs, leads, coil pack, oil change, rocker cover, inlet manifold, seals, upgraded air filter I decided to get the car chipped to see what BHP could be pulled out of her. Happy to say with all that work she was running on the first dyno 192bhp a massive improvement from standard 174bhp and all that from just replacing and upgrading some standard old parts with more expensive performance parts. Once the Chip was installed and the guys at the tuning store had done their works she was happily chucking out 216.4BHP With that I was more than happy and the work put in over the 6month period really showed. I then decided to have all but bumpers colour coded and did a few minor tweeks to the exterious to make her a clean standard example... I will add a full list of specs and work done soon, enjoy the pics feedback welcome

"Ride" by Michael Cooper - My Favorite Thing From the Maker Faire

This was, by far, my favorite thing at the 2008 Maker Faire. From Make's Description:Ride is a custom single rider helicopter with eight engines conceived & created by sculptor, Michael Cooper. It looks like more like a time machine invented by Dr. Seuss for George Jetson than anything you've seen in the air (or on land) recently.Michael Cooper is a sculptor who combines wood, metal, kinetics and mechanics with a twisted imagination resulting in beautiful, unique works of art that roll, spin, hop, contort and make people laugh while simultaneously scratching their heads. After 34 years as an art instructor at Foothill and DeAnza Colleges, he has now "retired" to his studio in Sebastopol where he spends his days devoted to sculpting, inventing and pushing the boundaries of form and function with a heavy does of humor.I know the pictures don't do it justice, and it's really hard to see everything, but take a long look and answer this question before you continue: Do you think it does/could fly? (Scroll down below the line and look at the pictures.)... did you look at the pictures first?There are so many reasons why it can't fly that I won't bother to discuss them here. However, the truly fascinating thing I liked so much was standing around Ride and listening to the conversations, and particularly watching its creator stage-manage the discussion. Lots of people wanted to discuss why they thought it could or couldn't fly - remember that this was the Maker Faire, so lots people here were builders or tinkerers (or at least thought of themselves as such). There were half-hour long heated debates about the tiniest of minutiae -- fuel line diameters and spiral exhaust ports, for example.Periodically, someone would gain the courage to think about the system as a whole and would approach the creator to ask, "So it flies, right?" He'd answer truthfully enough by saying, "Well, it's not done yet," and then launch into a detail, like the difficulty in synchronizing 8 engines; this would get the whole group rolling again. Later Saturday evening, when most of the kids had gone home and everyone else was outside listening to a band, a group of particularly crotchety old tinkerer-types were showing off their smarts and trying to outwit each other. After one onlooker had finished with his unnecessarily loud pronouncement of "based on my extensive experience building 1/6th-scale steam locomotive engines, I absolutely sure it can fly," another of the group tentatively approached the creator, and asked the inevitable question.Michael Cooper took his cue, dodged, and redirected into a discussion of how the transmission linking the 8 engines to the propellor was open, and the first time he ran it, he was probably going to get covered in grease. I burst out laughing.After they were all rolling again on how many cubic feet of compressed air the vehicle should optimally carry for its four pneumatic lifter feet, I quietly asked Michael how many people "got it" and how many people asked if it could fly. He confided that I was very much in the minority. Further, he got a big kick out of removing his name tag, and listening in to the can-it-fly conversations, too.I really hope I get a change one day to work with Michael Cooper to design and build a gorgeous Ride-like vehicle for me, so I get the chance to answer the question, "So, does it really fly?"

Solar - PV versus Solar Oven with Peltier

I was browsing the site as I am often wont to do, and spent quite some time revisiting old 'ibles covering various solar projects, almost all of which are heat related. I understand from general consensus that PV (photo voltaic) solar systems are very inefficient and one of the worst ways to harvest solar energy (when considering the cost of construction and the energy transfer capacity, etc.) Almost everyone who knows what they are doing suggest that the best (and easiest) way to harvest solar energy is to collect the heat - be it to heat air or water, cook food, or other such purposes.Now, I have recently been fascinated by a discovery relatively new to me, peltier units. These devices, for those who don't know, can work in one of three ways. They can harvest and/or produce either heat, cold, or electricity.Basically, if an electric current is run through a unit, it produces heat on one side and an equal amount of 'cold' on the other. Yes I know you can't produce cold - but for the layman, that is what we call it.Or, if one side is heated while the other side is cooled, the unit produces an amount of electricity from the difference in temperatures. One example I have seen and plan to make use of is in vehicles - if you place one or more of these on your exhaust manifold, or any other location where the engine produces waste heat, and airflow can reach it to cool the other side, you generate electricity from the waste heat energy that would otherwise just be . . . well, wasted.But it occurred to me today, if you had a unit attached in the middle of a solar collector, focusing sunlight on one side of the peltier unit, and isolate the other side of the unit in some cooling medium (perhaps even just air with a heat sink of some sort - more likely a cooling liquid though), how effective would this be at harvesting solar energy (heat) into electricity?Actually, I have been using the more common name of peltier, but I believe that for this application a seebeck unit (which is nearly the same, but different) would be required. As I understand it, Peltier units are used more as coolers and are almost always constructed with Bismuth Telluride (Bi2Te3) and used around room temperature and below; while Seebeck units are good for power generators are often constructed of PbTe or, SiGe as well as Bi2Te3 and are used at much higher temperatures.From http://en.wikipedia.org/wiki/Thermoelectric_effect :The effect is that a voltage, the thermoelectric EMF, is created in the presence of a temperature difference between two different metals or semiconductors. This causes a continuous current to flow in the conductors if they form a complete loop. The voltage created is of the order of several microvolts per degree difference.((more info can be found at the referenced wiki page on formulae etc.))Just curious on if this would ever be a decent way to harvest solar energy into electricity. I have also thought up using a thermal siphon solar heating system in which the liquid flows past one or more water wheels which power a small (and obviously slow) generator - but at that point I believe it would be so inefficient and limited in use as to just have absolutely no practical application. The peltier unit (used as a seebeck unit) would probably do better, but I am not certain, which is why I post the question.

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!

Fastest you have ever been.

I have a car, but no permit or license. One day, my brother told me to bring him something while he was at work. I was driving down the street going the speed limit or a little over and under. I turned onto the main road Speed limit, 50mph, and just went 50 or so the whole way. and when i got back onto the highway, this guy is following me to my bumper basically, so in the non passing zone just getting on i am going about 25mph, as you are getting on it is 35mph limit, as soon as it reaches 50mph, i jam the gas, it goes into passing gear and in no time i am doing 80mph. and on an S-curve still doing 80. On the stretch i am doing about 60mph, and decided i should just stick to the speed limit. Got a story? A Nice Morning Drive It was a fine morning in March 1982. The warm weather and clear sky gave promise of an early spring. Buzz had arisen early that morning, impatiently eaten breakfast and gone to the garage. Opening the door, he saw the sunshine bounce off the gleaming hood of his 15-year-old MGB roadster. After carefully checking the fluid levels, tire pressures and ignition wires, Buzz slid behind the wheel and cranked the engine, which immediately fired to life. He thought happily of the next few hours he would spend with the car, but his happiness was clouded - it was not as easy as it used to be. A dozen years ago things had begun changing. First there were a few modest safety and emission improvements required on new cars; gradually these became more comprehensive. The governmental requirements reached an adequate level, but they didn't stop; they continued and became more and more stringent. Now there were very few of the older models left, through natural deterioration and . . . other reasons. The MG was warmed up now and Buzz left the garage, hoping that this early in the morning there would be no trouble. He kept an eye on the instruments as he made his way down into the valley. The valley roads were no longer used very much: the small farms were all owned by doctors and the roads were somewhat narrow for the MSVs (Modern Safety Vehicles). The safety crusade had been well done at first. The few harebrained schemes were quickly ruled out and a sense of rationality developed. But in the late Seventies, with no major wars, cancer cured and social welfare straightened out, the politicians needed a new cause and once again they turned toward the automobile. The regulations concerning safety became tougher. Cars became larger, heavier, less efficient. They consumed gasoline so voraciously that the United States had had to become a major ally with the Arabian countries. The new cars were hard to stop or maneuver quickly, but they would save your life (usually) in a 50-mph crash. With 200 million cars on the road, however, few people ever drove that fast anymore. Buzz zipped quickly to the valley floor, dodging the frequent potholes which had developed from neglect of the seldom-used roads. The engine sounded spot-on and the entire car had a tight, good feeling about it. He negotiated several quick S-curves and reached 6000 in third gear before backing off for the next turn. He didn't worry about the police down here. No, not the cops . . . Despite the extent of the safety program, it was essentially a good idea. But unforeseen complications had arisen. People became accustomed to cars which went undamaged in 10-mph collisions. They gave even less thought than before to the possibility of being injured in a crash. As a result, they tended to worry less about clearances and rights-of-way, so that the accident rate went up a steady six percent every year. But the damages and injuries actually decreased, so the government was happy, the insurance industry was happy and most of the car owners were happy. Most of the car owners - the owners of the non-MSV cars - were kept busy dodging the less careful MSV drivers, and the result of this mismatch left very few of the older cars in existence. If they weren't crushed between two 6000-pound sleds on the highway they were quietly priced into the junkyard by the insurance peddlers. And worst of all, they became targets . . . Buzz was well into his act now, speeding through the twisting valley roads with all the skill he could muster, to the extent that he had forgotten his earlier worries. Where the road was unbroken he would power around the turns in well controlled oversteer, and where the sections were potholed he saw them as devious chicanes to be mastered. He left the ground briefly going over one of the old wooden bridges and later ascertained that the MG would still hit 110 on the long stretch between the old Hanlin and Grove farms. He was just beginning to wind down when he saw it, there in his mirror, a late-model MSV with hand-painted designs covering most of its body (one of the few modifications allowed on post-1980 cars). Buzz hoped it was a tourist or a wayward driver who got lost looking for a gas station. But now the MSV driver had spotted the MG, and with a whoosh of a well muffled, well cleansed exhaust he started the chase . . . It hadn't taken long for the less responsible element among drivers to discover that their new MSVs could inflict great damage on an older car and go unscathed themselves. As a result some drivers would go looking for the older cars in secluded areas, bounce them off the road or into a bridge abutment, and then speed off undamaged, relieved of whatever frustrations cause this kind of behavior. Police seldom patrolled these out-of-the-way places, their attentions being required more urgently elsewhere, and so it became a great sport for some drivers. Buzz wasn't too worried yet. This had happened a few times before, and unless the MSV driver was an exceptionally good one, the MG could be called upon to elude the other driver without too much difficulty. Yet something bothered him about this gaudy MSV in his mirror, but what was it? Planning carefully, Buzz let the other driver catch up to within a dozen yards or so, and then suddenly shot off down a road to the right. The MSV driver stood on his brakes, skidding 400 feet down the road, made a lumbering U-turn and set off once again after the roadster. The MG had gained a quarter mile in this manner and Buzz was thankful for the radial tires and front and rear anti-roll bars he had put on the car a few years back. He was flying along the twisting road, downshifting, cornering, accelerating and all the while planning his route ahead. He was confident that if he couldn't outrun the MSV then he could at least hold it off for another hour or more, at which time the MSV would be quite low on gas. But what was it that kept bothering him about the other car? They reached a straight section of the road and Buzz opened it up all the way and held it. The MSV was quite a way back but not so far that Buzz couldn't distinguish the tall antenna standing up from the back bumper. Antenna! Not police, but perhaps a Citizen's Band radio in the MSV? He quaked slightly and hoped it was not. The straight stretch was coming to an end now and Buzz put off braking to the last fraction of a second and then sped through a 75-mph right-hander, gaining ten more yards on the MSV. But less than a quarter mile ahead another huge MSV was slowly pulling across the road and to a stop. It was a CB set. The other driver had a cohort in the chase. Now Buzz was in trouble. He stayed on the gas until within a few hundred feet when he banked hard and feinted passing to the left. The MSV crawled in that direction and Buzz slipped by on the right, bouncing heavily over a stone on the shoulder. The two MSVs set off in hot pursuit, almost colliding in the process. Buzz turned right at the first crossroad and then made a quick left, hoping to be out of sight of his pursuers, and in fact he traveled several minutes before spotting one of them on the main road parallel to his lane. At the same time the other appeared in the mirror from around the last comer. By now they were beginning to climb the hills on the far side of the valley and Buzz pressed on for all he was worth, praying that the straining engine would stand up. He lost track of one MSV when the main road turned away, but could see the other one behind him on occasion. Climbing the old Monument Road, Buzz hoped to have time to get over the top and down the old dirt road to the right, which would be too narrow for his pursuers. Climbing, straining, the water temperature rising, using the entire road, flailing the shift lever back and forth from 3rd to 4th, not touching the brakes but scrubbing off the necessary speed in the corners, reaching the peak of the mountain where the lane to the old fire tower went off to the left . . . but coming up the other side of the hill was the second MSV he had lost track of! No time to get to his dirt road. He made a panicked turn left onto the fire tower road but spun on some loose gravel and struck a tree a glancing blow with his right fender. He came to a stop on the opposite side of the road. the engine stalled. Hurriedly he pushed the starter while the overheated engine slowly came back into life. He engaged 1st gear and sped off up the road, just as the first MSV turned the corner. Dazed though he was, Buzz had the advantage of a very narrow road lined on both sides with trees, and he made the most of it. The road twisted constantly and he stayed in 2nd with the engine between 5000 and 5500. The crash hadn't seemed to hurt anything and he was pulling away from the MSV. But to where? It hit him suddenly that the road dead-ended at the fire tower, no place to go but back . . . Still he pushed on and at the top of the hill drove quickly to the far end of the clearing, turned the MG around and waited. The first MSV came flying into the clearing and aimed itself at the sitting MG. Buzz grabbed reverse gear, backed up slightly to feint, stopped, and then backed up at full speed. The MSV, expecting the MG to change direction, veered the wrong way and slid to a stop up against a tree. Buzz was off again, down the fire tower road, and the undamaged MSV set off in pursuit. Buzz's predicament was unenviable. He was going full tilt down the twisting blacktop with a solid MSV coming up at him. and an equally solid MSV coming down after him. On he went, however, braking hard before each turn and then accelerating back up to 45 in between. Coming down to a particularly tight turn, he saw the MSV coming around it from the other direction and stood on the brakes. The sudden extreme pressure in the brake lines was too much for the rear brake line which had been twisted somewhat in his spin, and it broke, robbing Buzz of his brakes. In sheer desperation he pulled the handbrake as tightly as it would go and rammed the gear lever into 1st, popping the clutch as he did so. The back end locked solid and broke away, spinning him off the side of the road and miraculously into some bushes, which brought the car to a halt. As he was collecting his senses, Buzz saw the two MSVs, unable to stop in time, ram each other head on at over 40 mph. It was a long time before Buzz had the MG rebuilt to its original pristine condition of before the chase. It was an even longer time before he went back into the valley for a drive. Now it was only in the very early hours of the day when most people were still sleeping off the effects of the good life. And when he saw in the papers that the government would soon be requiring cars to be capable of withstanding 75-mph headon collisions, he stopped driving the MG altogether.
