DIY wind turbine 13, 100 + watt wind turbine for less than 10 dollars

I was able to build a wood wind turbine that can produce over 100 watts for less than $10.

The wind turbine has 3 homemade carved wood blades and a diameter of 4.5 feet. I used a door hinge to build in tail furling to protect the wind turbine against spinning too fast.
