Green-Trust.org and Woodhenge.org on Discovery’s Science Channel “Invention Nation”
Aired on December 17th, at 10pm Eastern time. The Science Channel is found on both cable and satellite TV. Check out http://www.treehugger.com/files/2007/11/invention_nation.php. You will see show hosts Chris, Nobu, and Micah learning to build a 1000 watt wind turbine from scratch, which helps power our off-grid home. More information on our wind turbines can be found at
http://www.green-trust.org, http://www.woodhenge.org and http://tech.groups.yahoo.com/group/axialflux/.
Get the Wind Power Workshop, by Hugh Piggott, to learn how to build your own wind turbine as seen on our Science Channel episode.

DIY vertical wind turbine of the Savonius style.
Notable is that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy and the generator is a recycled automotive alternator with magnets added).
Axle: 3 inch PVC piping from Home Depot
Bearings: 5 inch lazy suzan from Lowes.
Part 3 will cover connection to the battery bank with charge controller

How to Make a Solar Cell
Day One
– Preparation of TiO2-Coated Glass
1. Obtain 2 glass plates and clean with ethanol. Do not touch the faces of the plates once they are cleaned!
2. Determine which side of each glass plate is conducting with a multimeter.
3. Put the glass plates side by side with one conducting side up and one conducting side down (A).
4. Cover 1mm of each long edge of the plates with Scotch tape (B).
5. Cover 4-5 mm of the short edge of the conductive side up with Scotch tape (C).
6. Add 2 drops of the white TiO2 solution on the conductive side up glass (D).
7. Quickly spread the white TiO2 solution evenly with a glass pipette, sweeping

what kind of cheap thermostat could I use to control a passive solar water heater for my hot tub?
I want to build a batch heater or a passive coil system on a painted black corrugated metal backing. But I want to be able to stop the flow when the water gets to a set temp. It would be great to be able to just put in a car radiator thermostat but it would allow the water to get too hot.
Hello flagnsnarf:
You may need to install a low-voltage transformer with a thermostat and a solenoid valve. An automotive thermostat has too high a temperature setting.

With the hight cost of electricity continuing it rise without any guilt of raping the pocket of consumers or any conscious effort to change the direction of its output to clean up the environment and help restore Natures healthy balance people have started looking into and implementing renewable solar systems to cut their cost of power. solar energy comes in many packages with solar panels that utilize the suns energy, wind turbines that use natures wind resource to produce an abundance of renewable electricity, and an excellent source for power if you live near a stream, water based systems to produce power.
If you are looking to reduce the cost of electricity look no further. Home Made Renewable Solar Energy is one of the best and most reliable renewable energy sources available. The most cost-effective way to take advantage of the power of the sun is to build solar panels on your own. So,
