2- Vertical Wind Turbine
This small but powerful DIY wind turbine generates 50 watts of power. The vertical shape allows it to catch the wind and harness its power for usage in the home, boat, recreation vehicle, cabin or camp site. Light weight vertical blades are created from PVC pipe that has been cut in half and the motor is recycled from an old treadmill. Ideal ways to utilize leftover pieces of PVC pipe.
