### 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?

### 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.

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?

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...)

To solve this problem I try to learn things about nutrition, how to cook well (without losing a lot of nutrients for example), what are healthy products etc. In France we try to learn to people to eat fruits and vegetables (with a leitmotiv : "Manger 5 fruits et légumes par jour" / "Eat 5 fruits and vegetables a day") OK. But how are fruits and vegetables grown? with pesticides, chemical fertilizer, etc. :-/ Not cool at all ! Best solution : buy fresh organic products. But it's still more expensive than other (logically). So another solution : grow your own food *** Short introduction *** My name is Romain, this is the summay of my thinking : want to be in good health ? -> eat good food want to eat good food ? -> grow your own food My project / idea : Create a thing (rack, table, or whatever) to grow my own food (aromatic herbs, some vegetables, fruits) everyday, all year round. Some constraints :cheap but solidmovable (go indoor or outdoor) / lightweight / can be taken to pieces (-> plant pot on the one hand and rack on the other hand)self-sufficient in waterelectrical need only in winter (indoor) / low power -> LED light to help grown for darkest daysre-usable (no disposable component)scalable (possibility to create another same "thing") to multiply size of the gardenIdeas :Have a water storage in the top of installation (not too high, to be "easily" filled) but on the top to use gravity to water the plantsHave some specials lights to help plants growing when winter is arrivedHave wheel to be movableHave sensor to be (a little) connected, for me, not a specialist of cultivation, like light sensor and humidity sensor => which would drive the water valve and light power on/offMy little flat will not allow me to be self-sufficient in food, but to have some precious ingredient for everyday cooking.So if anyone had the experience of doing all or one part of what I thinking about, I'm open to all suggestions or recommendations. Thank you, Have a nice day !

### 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.

### 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.

### 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.
