Part Origin Cost Motor/Generator Ebay $26.00 Misc. pipe fittings Homecenter Store $41.49 Pipe for blades Homecenter Store $12.84 Misc hardware Homecenter Store $8.00 Conduit Homecenter Store $19.95 Wood & Aluminum Scrap Pile $0.00 Power Cable Old extension cord $0.00 Rope & Turnbuckles Homecenter Store $18.47 Electronic Parts Already on hand $0.00 Relay Auto Parts Store $13.87 Battery Borrowed from my UPS $0.00 Inverter Already on hand $0.00 Paint Already on hand $0.00 Total $140.62Not too bad. I doubt I could buy a commercially made turbine with a comparable power output, plus a commercially made charge controller, plus a commercially made tower for less than $750-$1000.
