DIY vertical wind turbine of the Savonius style.

Notable is that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy and the generator is a recycled automotive alternator with magnets added).

Axle: 3 inch PVC piping from Home Depot
Bearings: 5 inch lazy suzan from Lowes.

Part 3 will cover connection to the battery bank with charge controller
