Water wheel electricity?

We camp every year for two weeks beside a stream. There is no electricity available on our campsite, but we do have a number of things that we'd like to recharge over the two week period. There is a small (2 ft.) dammed waterfall/ rapids in the stream close to where we camp.  Does anyone know how I could make a water wheel electricity generator? Information on all aspects (how to build a water wheel; what type and where to get a generator; storage or regulator advice) would be greatly appreciated. Thanks.

A different water wheel design?

I posted this idea on the makezine forums recently and got 1 answer but it seems I did not explain what I meant too well so I thought I would try here to see what you think. See the diagram at http://www.nelliott.co.uk/maker/water-wheel.jpg Would this produce more power than a conventional water wheel? My theory is as follows: In the case of a normal wheel each bucket/segment when full of water has the turning power equal to weight of water x length of horizontal line such as the yellow one in the diagram. That is it's weight exerts a force to turn the wheel according to it's horizontal distance from the centre of the wheel. If instead of the normal wheel the 3 blue circles represent 3 sprockets.There would be a whole series of buckets attached to the red lines ( which represent a chain ).Water would pour into the buckets as shown, so it would simply propel the buckets vertically down.The turning power of each one of these would be equal to to weight of water x radius of large wheel. So each would have the turning power of the best one such as the line from H to the center of the wheel. As far as I can see this would mean a large increase in torque over conventional which I hope would easily offset the losses due to the chain drive. What do you think?

Boiling a fluid to make a inverse water wheel?

Ok, how about this; Submerge a waterwheel type structure with cups facing downwards on one side. Under the cups you have some kind of heating element. The fluid is methanol or some other low boiling fluid. A very small amount of heat from the element will produce bubbles, which rise and are caught in the cups, the wheel turns and can generate electricity or whatever. I'm using this principle in another application, but thought it could be quite an efficient means of generating electricity from heat. If the meths is sitting at forty something degrees and boils around 50, it shouldn't take hardly any energy to tip it over. And since you're effectively generating force from gravity (the weight of the fluid on the other side of the wheel) you're kind of getting ten times your force back. ie producing one litre of bubbles will give you 9.8 Newtons of force (for water, 8ish for meths). So (excuse my dodgy maths) 125 litres of bubbles in an hour would give you 1 kiloWatt hour? One cola bottle per minute, doesn't sound very much and that much energy could easily be produced through concentrated solar. Slight risk of explosion... How efficient do you think it would be, overall?

Sydney Opera House on wheels!

I live in a semi-rural area.  We are hours from a decent motorway, but hip-deep in caravan parks. Given the UK law that limits trailers to 50mph, I am generally disapproving of anything towed. However, this trailer tent designed by Axel Enthoven is a thing of beauty and luxury. The Opera trailer tent has features including central heating, teak flooring (and a veranda!), ceramic toilet, electrically adjustable twin beds (which can be joined into a double), kitchen sink (of course), onboard water boiler (which supplies a fountain?), fridge and low-energy LED lighting “from awning to floor” (yes there are uplights!). Unfortunately, beauty has a price - €24,000 puts it in the price-range of campers with engines and no restriction to 50mph... Your Suite in Nature via Notcot.

Generate Power from water leaving your home

It occurs to me that a lot of power is supplied to pump water into my home -- into my showers, dishwasher, sinks, toilets, etc. And then, as that water plummets from the second story bathroom back into the ground, it builds up a lot of power due to gravity -- and it just goes whooshing away. So let's develop some sort of mechanism that will harvest the energy of that moving water as it leaves our homes. The initial thought is turbines or wheels, sure, but you have to remember the stuff that is leaving the house in that water: hair, food scraps, and all your bathroom functions. So we need to either develop a system that cannot be jammed, filter & divert the water before it reaches our device, or develop a system that harvests the energy without interfering with the flow.

iRobot Scholarship idea : Pool Cleaner

I've seen mods for the roombas before, where the robots are water sealed, and then the wheels are turned into propellers. My idea is that I could water proof the robot in plexi glass, or something, and then a net on it, to collect all the leaves, dead bugs, and other stuff that collects on the surface of a pool. normal pool cleaners only vacuum the floor of a pool, and it takes days for floating leaves and other grime to sink to the bottom. With a robot like this, I could just set it in the pool, and let it clean everything up. What's nice is, when company is coming over, it's embarrassing to have a dirty pool...this modification would allow you to quickly clean up your pool-even on short notice. Update (for some clarification): What I would want to do, is make a case for it, so that you can simply remove the wheels, and connect the propellers/steering device to where the wheels were, then just place the roomba in the watertight case, and it would be able to swim around and clean! Also, i'm working on some sketches of how it would work. I'll post those when they are done.

FREE DOWNLOAD 1915 ELECTRICITY FOR THE FARM

This is not a scan of the original book, but the original book converted to text with OCR, and strictly proof read with QC controls. Thus the charts, formulas can be copied and pasted into something else.  www.gutenberg.org/etext/27257   ELECTRICITY FOR THE FARM LIGHT, HEAT AND POWER BY INEXPENSIVE METHODS FROM THE WATER WHEEL OR FARM ENGINE BY FREDERICK IRVING ANDERSON AUTHOR OF "THE FARMER OF TO-MORROW," ETC., ETC. New York THE MACMILLAN COMPANY 1915   PREFACE This book is designed primarily to give the farmer a practical working knowledge of electricity for use a slight, heat, and power on the farm. The electric generator, the dynamo, is explained in detail; and there are chapters on electric transmission and house-wiring, by which the farm mechanic is enabled to install his own plant without the aid and expense of an expert.    With modern appliances, within the means of the average farmer, the generation of electricity, with its unique   conveniences,   becomes   automatic,   provided   some   dependable   source   of   power   is   to   be had—such as a water wheel, gasoline (or other form of internal combustion) engine, or the ordinary windmill. The water wheel is the ideal prime mover for the dynamo in isolated plants. Since water-power is running to waste on tens of   thousands of our   farms throughout   the country,   several chapters are devoted to this phase of the subject: these include descriptions and working diagrams of weirs and other simple devices for measuring the flow of streams; there are tables and formulas by which any one, with a knowledge of simple arithmetic, may determine the power to be had from falling water under given conditions; and in addition, there are diagrams showing in general the method of construction of dams, bulkheads,   races, flumes, etc.,   from materials usually to be found on a farm. The tiny unconsidered brook that waters the farm pasture frequently possesses power enough to supply the farmstead with clean,   cool,   safe   light   in place of   the dangerous,   inconvenient oil   lamp;   a   small   stream capable of developing from twenty-five to fifty horsepower will supply a farmer (at practically no expense beyond the original cost of installation) not only with light, but with power for even the heavier farm operations, as threshing; and in addition will do the washing, ironing, and cooking, and at the same time keep the house warm in the coldest weather. Less than one horsepower of energy will light the farmstead; less than five horsepower of energy will provide light and small power, and take the drudgery out of the kitchen.   For those not fortunate enough to possess water-power which can be developed, there are chapters on the use of the farm gasoline engine and windmill,   in connection with the modern storage battery, as sources of electric current.   www.gutenberg.org/etext/27257

12 Hurricane Preparedness Projects

I read some of the 12 projects. I did one myself since I live in Puerto Rico, went through Hurricane Irma this past Wednesday (Sept 6th) ,have been though several hurricane sin the past (since 1964), and will go through a new one (Hurricane Jose) this weekend. In most occasions, we lost power and water for days. I lost only power for 30 hours after Hurricane Irma. My own project was a two part installation for when I lacked water (I have a generator set for power): 1. Install a 50 gallon cistern on my roof to store potable water for cleaning and bathing needs 2. Install a pressurized 20 gallon tank for showering The 50 gallon cistern was actually a large trash barrel with a removable cover ($40), which I added two 1/2 inch plastic faucet valves, one near the base as a gravity fed output, and one on the cover as a water inlet. After cleaning the barrel, and attaching the valves, I fixed the barrel (now a "cistern") on my roof (over a beam for weight distribution) with two wire guides. I attached a plain water hose from an external faucet to the top valve to fill the cistern. Then I attached a new hose to the bottom valve and ended that with a regular sprayer. I fitted this into the bathroom over the toilet tank and near the sink, so it can be used for face and hand washing, and for filling the toilet tank after each flush. The pressurized water tank is a unused water heater that can hold up to 120 PSI. I replaced the cold water inlet with a cap and a auto tire valve by drilling into the cap and pulling the tire vale through (same as for a wheel hub).. I installed a 1/2 inch faucet on the hot water outlet and a short (pressure resistant) water hose, and finished it with a water sprinkler. Then I installed a.new 1/2 inch valve on the drain.for the lower water inlet.  I attached the hose from the cistern to the lower valve, opened the valves on the cistern output and tank input, and removed the inner stem from the tire vale. When the tank was full, some water will spurt out from the open tire valve. Then I close both valves, remove the cistern hose, reinstall the tire valve stem, and use an electric air pump to apply pressure up to 50 PSI.  Now if I open the water sprinkler, i have a hand held shower!  After one use (about five minutes) the pressure can drop but if I have electrical power, I can reapply air pressure again. After several showers, I release the remaining air pressure at the tire valve, refill the tank from the cistern, and apply air pressure again. This has worked for years, and I keep everything ready for the next storm of when I have no water supply.

Need help with Aeroponics misting system any ideas? Answered

I've been struggling to build an aeroponics system and the only problem I have right now is the misting system. I purchased some misting nozzles off amazon that I inserted into some vinyl tubing and sealed with a silicon sealant. I used a small DC 6V pump powered by my Arduino to pump the water to the nozzles. Now the little pump couldn't provide enough pressure to create a mist of water (I think its pump rate was something like 15GPH) it came out with some of the water leaking while a steady stream sprayed in four directions. So my question to the instructables community is was it my little pumps fault or did I get ripped off buying bad nozzles? What pump should I buy that will pump enough pressure to create a mist? here are the nozzles I bought and here's the pump I bought: http://www.amazon.com/gp/product/B004HHW0FU/ref=oh_details_o01_s00_i00    <-- the pump http://www.amazon.com/gp/product/B004U3MRIG/ref=oh_details_o02_s00_i00     <-- the nozzles One more thing, I was thinking of a misting system which I'm unsure will work. I got the idea driving behind a truck after the rain when the road was wet. The wheels were spraying a mist behind them as they drove over the wet road. Could I simulate that effect at all with an electric motor and a small wheel?

Things your instructor never told you...

I was chatting about changing driving tests with a colleague today, and I realised that I had been driving longer than she has been alive, in often rougher conditions.That means I knew a couple of things about driving that she didn't. Others here are in a similar state as I am, but many are in a similar state to her - young, and only learning (or yearning to learn) to drive.How about sharing tricks that make your driving easier and/or safer that your driving instructor never taught you?Here're my starters:Reverse is lower gear than first - if you're stuck in a pothole, or trying to get up a hill your car can't quite manage, try again backwards.Watch your thumbs - when driving in water, snow or mud, or otherwise uneven ground, keep your thumbs on the steering wheel, not in the "hole" - sudden unevenness can kick the wheel and spin it with enough force to break thumbs, especially if you don't have power steering.Brake as you enter a sharp turn, accelerate as you leave it.In urban driving, skill beats power every time (me and my 900cc mini could beat my mate and his three-litre Capri Sport across town every time).On icy wet roads, slow down gradually with the gears instead of with the brakes

Measure RPM and MPH on motorcylce with Arduino

Hi all, I have an idea for an Arduino based instrument cluster for my cafe racer (1980 xs400). My question is what kind of rotary encoder I should use to measure the rotation from the cables coming from the engine block and front wheel that went to the original cluster (shown in pictures). I want something that won't break at higher RPMs and is more or less water proof. I have an idea of how to code this on the software level as well, but I'm not to experienced with C/C++ so any help there would also be appreciated. The end goal for this part of the cluster is to output the RPM and MPH to respective WS2812B 5050 LED strips, and possibly a small oLED later down the line. If something could be made more clear on this post let me know and I'll try to elaborate. Thanks again

How to seal a system containing ethanol, but low friction?

Still working on my solar device (in Copenhagen now), and it's coming along fairly nicely. Should hopefully have a full instructable in a couple of weeks. However, I'm having problems at the moment trying to keep the thing water tight, where the axle leaves the system, taking out the rotational motion. I'm using the bearing housing from an old bike wheel (photos to come) and I've got it sealed well where it's attached to wall of the container, but the ethanol is flowing pretty freely through the bearings themselves. I need it not to. I could use something like an O ring to seal the axle, but friction is a big issue. I wanted to pack the whole axle and bearing housing with grease, but grease dissolves in ethanol. Solutions? Is there anything grease like which isn't soluble in alcohol? Salt, maybe? Cheers all. (Nearly there...)

Can diesel be separated from petrol?

​this is a reply to my last question as for some strange reason I can't reply and leave a comment to the thread. ok thanks to those replies,  I am in oz and the reason I've asked is due to free diesel that has been contaminated with petrol being offered to myself. So, given I have free fuel I am prepared to treat, separate, spend some $ on in trying to produce diesel and petrol separate. I have looked at a continuous separation distill unit but I don't know how it works and the safety factor, don't want to make a bomb! Other ideas are leave the diesel out in sun and evaporate petrol(not so good for environment and water getting in diesel) or add oil to mix. Most of the fuel mix is majority petrol and minority diesel, although exact ratios are unknown. I have run my lawn mower on it quite well so given that it is mostly petrol, can I either;1. Add more petrol pure to further dilute the diesel. 2. Add an octane booster to over come the diesel influence. And specific comments and answers appreciated

How to turn on and off a stream of gas?

The exact setup I have is a little difficult to explain, but basically I'm designing an extremely simple heat engine, based on boiling ethanol, and need to be able to mechanically alternate the flow of vapour. I have a little boiler, sealed except for a pipe out of which the vapour escapes. This lifts the column of ethanol in the pipe, pouring it into a water wheel which turns. The ethanol then runs back through a second pipe into the system to be pumped up again. It works, and fairly well since I'm not looking to get a lot of power or efficiency, but only if I pinch the tube on and off. This allows the bubbles to collapse, which sucks in more ethanol to replace them. When I release the tube the bubbles rush out, lifting the eths, and repeat. I have two valves to keep the system one directional. So now I'm looking for a way to automate the opening and closing of the gas feed. I've been trying a few things but nothing seems to work well enough yet. The other consideration is that; due to the nature of the larger project, whatever I use has to be extremely simple to construct, preferably from reclaimable materials. 1 second on, 1 second off seems to work best. Any ideas? cheers, Daniel.

Cutting PVC Pipe - Lengthwise for guttering

Ok, here's one I thought I'd throw open to the masses.... I'm knocking off the last of a fully automated self-sufficient watering system that runs completely off grey/rainwater. However, the coke can guttering is not working in this position as it has previously :(  I was thinking of using PVC piping, cut lengthwise for guttering. However, I'm working out the logistics of cutting it. It can't be cut directly in half - this would be too shallow to catch the runoff from the chicken shed. and funnel it down to the tanks, so I'm looking at removing a chunk of the top.  And I also have no table saw. Wheee. What I do have Dremel (x2) with associated cutting wheels Jig saw (With associated plastic cutting blades) Circular Saw Mitre saw Hand saws (tenon, crosscut, hack, pruning, etc) So, here's one that I'm throwing open. With the tools I have, how would you do it?  I'm leaning towards the dremel, but there would probably be issues with maintaining a straight line (not that I care about some warp, it's a gutter)   Ideas? *EDIT*  Ended up using a jig saw with an acrylic cutting blade. Worked a treat.

Pipboy 3000 SCUBA computer? Answered

I am a fairly avid scuba diver, I try to dive every other weekend, but I think I want a dive computer. It can calculate my pressure group, weather I do a multilevel dive or use a different nitrox mix. A good dive computer should also tell you your current and max depth, tell you if you are ascending or descending to quickly, include a compass and maybe even show you how much air you have left. It should also be easy to use. I also like Fallout (3 and 4 are the only ones I have played), and the wrist mounted computer that the hero always wears, called the pipboy 3000, looks like it would be the perfect dive computer. Not only could it be a dive computer, but it also may be a watch, or even an mp3 player while above water. Although the knobs, scroll wheel, and "RT" and "LT" buttons make using it seem more complicated, the size of the unit allows for a larger processer, allowing for a similar GUI as that of the "real" pipboy. Such a GUI would be able to display info in Standard English, such as "Set your nitrox % mixture." and letting you use the wheel to set the air mix that you will be using. I guess that having “confirm” and “back” buttons would help as well. The Geiger counter can easily be used as a depth gauge, which works, as the deeper you go, the more dangerous. The dive computer settings could be where the quest, world, radio, etc used to be, and you can have dive info and other things like reminders where your stats would be. The time could be displayed on the upper right side of all screens except the time screen, which shows the month day and time, which would be where your “weapons” usually are. Other time related functions can be used to fill the sub-sections like stopwatch, timer, etc. There could also be a screen that shows your limb conditions that you can switch to, just like anyone you meet in the game who has a pipboy, you see that screen. All this will have to be water resistant to maybe 70 to 100 feet, made of a hard metal, and fit comfortably. If anyone has any ideas on how to make and program this, or know of any job shops that can make and program this please answer. I know someone can do it, I wouldn’t know where to start looking. I probably made this sound much more complex than most likely is. I am basically looking for a diving computer that looks like a pipboy 3000 and is easy to use. I don’t really need an mp3 player. Again, if anyone has any imput on how to build and program it, or if anyone know any jobshops I can send this request to to have this made, please let me know. this is too good of an idea to forget about. Edit: Thanks to all who answered, And I think just the fact that it IS entirely possible is good enough for me, although price is probably the limiting factor. Thanks again.

Oops!

Over the years I've done a lot of things that didn't work out well, and I try learn something from them  hoping to avoid similar problems in the future. I think ibles  needs a place to share these 'educational moments'  to help others avoid pitfalls and to console with laughter anyone who is sitting amidst the ruins of their own project.   So here's the  place to share.    I'll go first........... My first dramatic failure at about age 8 - Gluing glitter onto balloons. Not a good idea. The glue popped the balloon (I think it was 'airplane glue' ) The result was glue and glitter everywhere (including in my eyes) and a lot of unhappiness. Then there was the hot glue surprise -  Using a glue gun to close drip irrigation holes in a garden hose.  It plugged the holes and worked just fine in the overcast cool spring weather. Then a rare sunny day  heated the hose, and all those plugs melted and the holes started jetting water.  I hadn't realized how hot a green hose in the sun could get. And I have made some just plain stupid moves - like spending hours pulling all the shreds of paper out of the toothed wheels on the paper shredder.... you know how they get sucked inside.  After getting it all clear I thought I might as well lubricate the thing with spray silicon stuff.  So far so good. And then I was so excited to see how it much better it would work, I turned it on.  Flash of flame, slightly singed eyebrows, and a TOTALLY dead smoking shredder.  Ummm.... it's really worthwhile to let solvents totally evaporate before turning on electrical things.

Watch out for falling satellites

Watch out for falling satellitesWith no one at the wheel, should we be worried about the large US spy satellite now headed for a crash landing?US spy satellite 193 is predicted to de-orbit less than gracefully in Feburary or early March. The chances of it actually hitting a populated area are exceedingly small, but perhaps you can catch a few micrograms of it using Kiteman's How to catch a star Instructable.What is happening?An out-of-control US spy satellite will crash to Earth in the coming months, government officials say. The satellite is large enough that remnants are likely to survive atmospheric re-entry and strike the Earth, sometime in late February or early March, says Gordon Johndroe, a spokesman for the National Security Council.Is that normal?"This is relatively routine in that satellites de-orbit all the time," says Johndroe. Pieces of uncontrolled debris heavier than two tonnes -- mostly discarded rocket stages -- crash to Earth as often as once every three weeks, says Jonathan McDowell, an astronomer and launch observer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts.Many discarded pieces retain some power, so that controllers on Earth can guide them to a point far from human habitation, usually using a final dive into an ocean. In 2001, Russian space officials broke up the old Mir space station in this way over the South Pacific. That's not the case for this US one, however."Obviously, we want to take a look at the potential for it to land in a populated area," says Johndroe.What are the chances of it crashing through my roof?Exceedingly slim, says McDowell. Remember that some 70% of the Earth is water, and most lands are void of people. "There is no reason for people to get alarmed about it," he says.According to the NASA Orbital Debris Program Office, there have been no confirmed instances of serious property damage or injury caused by crashing debris in 40 years.

Laugh a Little

Greetings!      Where I use to live my local paper posted some funny stories or or sayings titled "Laugh a Little" hence the name. I decide to post some of them to see what you think. None of these are ones that I made up, they're all from the paper. If you want me to post more I will. I have lots of them.      Enjoy.                                Questions that haunt me! Can you cry underwater? How important does a person have to be before they are considered assassinated instead of just murdered? Why does a round pizza come in a square box? What disease did cured ham actually have? How is it that we put  man on the moon before we figured out how to put wheels on luggage? Why is it that people say they 'slept like a baby' when babies wake up every to hours? If a death person has to go to court, is it still called a hearing? Why do people pay to go up in tall buildings and pay to look through binoculars at things on the ground? If the professor on Gilligan's Island can make a coconut radio, why can't he fix a hole in a boat? If corn oil is made from corn, and vegetable oil is made from vegetables, what is baby oil made from?                                 Church Bloopers  The fasting and prayer conference includes meals. The sermon this morning 'Jesus walks on water.' The sermon tonight: 'Searching for Jesus.' Ladies, don't forget the rummage sale. It's a chance to get rid of those things not worth keeping around the house. Bring your husband. Don't let worry kill you off - let the church help. Remember in prayer the many who are sick of our community.  A bean supper will be held on Tuesday evening in the church hall. Music will follow.

Something is making a mysterious noise.

So it's been awhile! Between school, homework, work, and playing with gadgets and such, I haven't gotten the time to post or make an instructable for quite a long time. But now, I'm back with a question. I see lots of new users here, and to them I say welcome to the community! You are going to love  it here, everyone is helpful, and you'll find answers to just about everything. I also see some members here that were around when I still used instructables. Remember me? How are things? :P Ok, so now for my question. A few weeks ago, after flushing the Toilet, a strange noise began behind our refrigerator. It was king of like a rattling, but not so much that as say, a prize wheel at a gameshow spinning and hitting something heavy. It's really quite odd. The refrigerator is a model with the built in water and ice dispenser. I googled it, and many seem to say it is something called "Pipe Rattling", but I don't think that is what it is, because it only started a couple of weeks ago and we have had this fridge for a year. I have drawn a diagram of the first floor of our house to help you get a better understanding of where the fridge is in comparison to the bathroom and the toilet. Like I said before, the noise only occurs after we flush the 1st floor toilet. Another odd thing about it is when the noise occurs. It can make this rattling as the toilet is flushing, directly after the toilet has flushed, and it has happened up to a minute after the toilet is finished flushing and refilling the bowl. The noise goes for about 5-8 seconds each time, and it only sounds once after each flush. We have not made any additions to the house before or since it started, have npt experienced any severe weather, and have not modified any plumbing in the house in quite a while, and never in that area of the house. In the incredibly bad sketch I made, you can see the bathroom, and the incredibly bad drawing of a toilet. The fridge is indented in the wall so there are cabinets surrounding it. Any thoughts on what this noise can be?

Take a tour of Instructables!

There's so much cool stuff here, I thought people (new and old) might enjoy a guided tour. Instructables is a web-based documentation platform where passionate people share what they do and how they do it, and learn from and collaborate with others. These awesome people make it all happen. The seeds of Instructables germinated at the MIT Media Lab as the future founders of Squid Labs built places to share their projects and help others; more history is here. Instructables is the combination of a number of things. First, there are the Instructables themselves. These are step-by-step descriptions of things people want to share. They are educational, inspirational, and often replicable. The Dachshund Wheel chair is my favorite. A passionate user shared something close to his heart, and has had a positive impact on many lives.There's the whimsical: Magnetic Acrylic Rubik's Cube. And, of course, the whimsical inspired by the whimsical: Magnetic Rubik's Dice Cube. And, the plain ridiculous: How to Get a Free Yacht and its complete saga. A cornerstone of what makes Instructables great is the comments. People ask questions, give praise, or offer improvements; this sets up a conversation between the project author and the community. Check out this cookie recipe where the author responds to a question about substitutions for someone who wants cookies now.Many of the best Instructables have won one of our contests: Show Your Heart Valentine's Day Contest, Holiday Homemade Gifts contest, Take Thanksgiving to the Next Level contest, Halloween Project contest, and The Magnet Challenge. Instructables has a lively forum for opinion and discussion. Really smart and talented people hang out here. Have a look at a forum topic on water tunnel testing complete with Reynold's number equations.Finally, what really makes Instructables great is the community surrounding it. These are passionate people that want to share what they did and how they did it. In recognition of this, Instructables won the 2006 Wired Rave Award for industrial design. Instructables gave power to the individuals so they could positively impact the world. Also, check out some of the news articles about Instructables.

Clock based dripper tracker for solar applications (panels solar cookers, etc)

I just made an instructable and entered it in the green competition. Way too late of course. the picture shows the generic driver of a battery wall clock. I have adapted one by removing the 2 concentric pipes in the middle that run the minute and second hand to just leave the hour hand driver that i use to drive a "gear" wheel. Anyway, the idea is to do a little dismemberment of clocks, and use the little drive mechanism to control the turning of a solar reflector to continually have the sun focused on what you cook. My current edition of it seems to be working. I believe a simple tracker is sorely needed for solar applications. Once a reliable one comes on the market, you may see new backyard applications popping up. For instance, I cook soil! I stick it in a big black pot, and steam it in my tracking solar cooker for a day. This generally reaches 60 or 70 C (It is a big pot and soil has a low thermal conductivity) which is enough to kill seed eating bugs and weed seeds. I end up with excellent home made seeding soil. Solarization is also possible. Again, a big pot or can, put in all your rotten insect infested fruit, cook for a day, and next year, less bugs on your trees and less sourse of fungal infection. It might even end up as a stage in the processing of compost. Lots of weed roots and seeds survive the compost heat. But they might not do so good after a day at 70 C! Tracking might even be accurate enough to make quicklime! Quicklime is made from limestone CaCO3 that is heated enough to drive off the CO2. You then slake the lime (add water) and it gives off a lot of heat. Heat storage potential? and you have Ca(OH)2 which is the basis for lime plaster. Parabolic dish concentrators can get hot enough to cook limestone. but I do not know the details. There is more of but that will do for now. I hope people try this and prove to the holy free market that simple trackers are needed! Brian White

Solar Filter for Telescopes

Having seen some predictions of increased solar activity over the next two years, I decided to make a filter so I can check it out with my trusty telescope. To start out, I constructed the rig shown in photo A, and practiced with it by cutting disks of plain glass. Make a table like that in photo C so you can make a continuous score on the glass, without stopping. Put oil on the wheel of the grass cutter. Be sure that the surface you work on is flat. You can skip this if you want a square filter. After scoring, your glass should look like that in photo B, with a uniform and even cut. Next, put the scored glass on a soft surface like a mouse pad, with the scored surface wetted with water and face down. Press on the back of the score with a dull nail to start a crack. By continual pressing you can watch the crack propagate all the way around. Then, make 8 radial scores from the circle to the edge of the glass and propagate those cracks in the same manner as the disk. When you do it right, you get a result like photo D, where the pieces were separated for illustration. When you get good at this with regular glass, you can cut the mirror into a disk. With the mirror, you score the glass on the side that has the metal coating. Or, you can just cut the mirror in a square instead of a circle. Photo E shows an uncut and a finished cut mirror. The mirror came out of the back of a discarded projection TV. Some of the mirrors are plastic films, some are second surface, some are first surface glass but the metal coating is too thin. There are many variations, but you need to find a first surface glass mirror that reduces the light level by 12 stops (as measured by a LunaPro SBC light meter). Photographically, this is like reducing the light level from F1.4 to F64. This level of light reduction will be hard to find. WARNING: Use of a mirror with a thin reflective coating can result in eye damage if used to view the sun through a telescope. I have access to a smaller commercial filter to use as a guide. This filter produced a bright blue image of the sun, so I added a red filter at the eyepiece. This combination produced a normal yellow image of the sun. There were no significant sunspots visible, so I didn’t bother taking any pictures. The Filter is mounted to a screw-in lens cap.
