foils self adjust to maximize power.
It rotates vertically instead of horizontally. (also known as a VAWT) . There are many different designs on the INTERNET where the foils adjust, but this is my own unique design. What makes this design nice is that it is easily scaled up or down in size, and there is no welding required.
Most of the parts can come off with a screw driver so you could really play with the sizes.
Most of the tools used are standard tools.
There are two videos that I have made in association to this instructable, one shows the mechanics of how it works, the other is a short video of the working prototype.

Mechanics of how it self-adjust: http://youtu.be/X4YFPb60euE
( In this video I used gears instead of pulleys, but the mechanics are the same, and the blades/foils adjust the same)
Step 1: Tools and materials
Metal Grinder ( with cutting blade)
optional Tap die set, ( Screw and bolts will work also)
3 timing pulley. I used two 60 tooth pulley and 1 x 30 tooth pulley
2 timing belts ( Pulleys and belts purchased through "spd-si", Sprocket and chain would work as well)
multiple bearings . ( purchased online at "VXB")
Aluminum sheet metal ( any big box store)
Aluminum 1/2" inch tube, and 1 1/4" round tube ( Big box store)
1/4inch and 3/8 inch metal rods ( big box store)
JB weld ( epoxy)
Polymer spacers (easy to drill and cheap, purchased at big box store)
Flat aluminum bar 1/8" thick, 1 1/2 " wide
2 x 1/4 inch polymer thrust bearing
1 x 1/2 inch thrust bearing
