DIY Wind Turbine 15, car rad fan motor more power

In this video I get alot of free motors from the local car shop.

I use a flat car radiator fan motor in the wind turbine with a 5 to 1 V pulley ratio. I was able to get over 6 Volts while charging.

In total I got over 6 watt hours. Assuming this wind speed is the average I could pay back my $8 wind turbine in only 2 years and then get free electricity after that.
