Créer sa turbine a vent

Une 'eolienne' a fabriquer sois-meme. Avec les instructions sur le site de Solar Flower: http://solarflower.org/tutorial.php?tut=vawt#.Vhz-3GAyB-M

 

This is a Vertical Axis Wind Turbine which uses wind energy to drive things like air and water pumps for cooling, irrigation and similar, or an alternator/generator for producing electricity.
The turbine uses the 35-40% mechanically efficient Lenz2 lift+drag design. It is made entirely from scrap materials except for the bolts and pop rivets, and should cost about $15-$30 for the six vane version, which can be made by two people in six hours without much effort. 
The three vane version has been successfully survival tested to 80 km/h sustained winds and the six vane version to 105 km

Full power curves have yet to be calculated for this particular build, but according to Mr Ed Lenz's calculator (http://windstuff.org/calc/calc.php) a six vane at 0.93 meters diameter and 1.1 meters high with a 90% efficient alternator should produce at least 135 watts of electricity in a 30 km/h wind, and 1.05 kilowatts at 60 km/h.

The materials listed in this tutorial are to make the three vane version. Double everything except the bike wheel for six vanes.
