So how much did all this cost to build? Well, I saved all the receipts for everything I bought related to this project.

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
$140.62

Not 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.
