Building a Vertical Axis Wind Turbine ( VAWT ) TOOLS- Jigsaw and or band saw- Hand saw- Lathe- Drill press or hand drill- Drill bits- Screwdriver- Tab tool- Ruler- Pencil- Compass- Sanding paper- Vise ( it makes work more easy)- Wrenches- 2 clamps PARTS- PVC pipe- Waterproof wood "concrete form plywood is the best"( if you don't have that you will have to protect it with a coating )- 2 Bearings ( bottom one needs to be able to handle a load )- Grease nipple - Wire rod ( 2 sizes ) ( 1 big one and 4 small ones ) ( Stainless if possible ) - Bolts and washers ( 2 sizes ) ( Stainless if possible )- A piece of 40 mm round aluminium ( Alloy ) ( it will hold the bottom bearing )- 2 Angle irons- 3 eye screws.
MiniMill. How I built an electricity producing Solar Panel. Several years ago I bought some remote property in Arizona.
I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property.

Other factors will need consideration for proper conductor sizing including local codes and conditions. Always consult with and use a qualified electrician for any electrical work.

Last updated at 21:09 15 September 2007 It sounds too good to be true - not to mention the fact that it violates almost every known law of physics.
But British scientists claim they have invented a revolutionary device that seems to 'create' energy from virtually nothing. Their so-called thermal energy cell could soon be fitted into ordinary homes, halving domestic heating bills and making a major contribution towards cutting carbon emissions. Scroll down for more... Even the makers of the device are at a loss to explain exactly how it works - but sceptical independent scientists carried out their own tests and discovered that the 12in x 2in tube really does produce far more heat energy than the electrical energy put in. Windbelt Micro-wind, 10 Times Cheaper Wind Energy!! [Run time: 2:05 min] I hope you enjoy this short video of Shawn Frayne, a young inventor that has created this device to generate, on the micro-scale, energy for LED lights and radios in developing countries.
This is the first approach that uses aeroelastic flutter to create super cheap electricity. We’re talking about changing the way wind energy is harvested and captured. Frayne won a 2007 Breakthrough Award from Popular Mechanics, and he deserves it. This incredible technology is 10-30 times more efficient than the best micro-turbines. So, Frayne hopes to fund third-world distribution of the Windbelt through sales in first-world applications. Soliant Energy. C:\IMAGES\OMNIPAGE\DATA\hm2.htm. In collaboration with Norman Rostoker from UC at Irvine, we have designed a novel type of fusion reactor, the Colliding Beam Fusion Reactor (CBFR).
It uses protons (p) and boron-11 (11B) for fuel. Fusion reactions produce only three helium-4 (4He) nuclei, and nearly 9 million eV energy. The Sietch Blog » Watercone – An Ingenious Way To Turn Salt Water Into Fresh Water. The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun.
The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use. The Watercone is surprisingly a cone, that you place over a pan of salty water (or over a marsh, or any damp ground) leave it out in the sun, water evaporates, the condensation trickles down the side of the cone, at the end of the day you flip it over, remove the cap at the top and drink the water. This device has the potential to really do a lot of good for a lot of people. Organic Mechanic - Discover Smart Energy.
