Ted Baer has created a series of small windmills designed for third world use over a period of three decades. This first in the series has evoved in simplicity and power. The aluminum vanes are constructed from a building flashing roll utilizing the pre-existing bend of the roll in construction. Two 16 " sections are rivited together to make one vane. The vanes clip on the spokes of the bicycle wheel using a "bent nail" and a bend in the vane. Detailed pictures will be provided shortly. The generator is a surplus permanent magnet motor and the endless belting is purchased to length from online sources.
Output is a respectable 2 amps at 12 mph providing a cost effective alternative to a solar photovoltaic panels (if wind is available). The total cost of the windmill is less than $80 purchasing most items new (off-the-shelf).

The test rig is a Windstar van with top rack and platform. The tripod is a roof TV antenna mount. Windspeed, volts and amps are taken and recorded with a digital camera. Video clips will be provided shortly.
The vanes attach by folding the aluminum flashing over one spoke and hooking a bent nail around a second spoke, The bent nail is inserted through a drilled hole in the vane.
