    The volts per RPM ratio favours using higher voltage motors as   
   generators for wind power. 40 volt computer tape motors work   
   reasonably well, while 90 volt treadmill motors have a much better   
   chance of putting out useable power, particularly with an active   
   voltage controller (downconverter)
