But that 55mph wind speed would need to be straight line air flow, no obstructions in front or behind it, at all.
Ok, thanks. 200 Watts / 12 Volts = 16.67 Amps. I have a lot of commute miles, but my average speed is sub-50 MPH because of the congestion. This is mostly a mental exercise for me. If I were to try this, it would be on condition that I get my hands on a cheap 12 volt motor. My main goal would be to make a chart of X amps at Y speed.

I think this is a job for a Studebaker :
