Propeller generator

Stevek · 04-08-2006, 17:56

Does anyone out there use thier free spinning prop to generate power? I have an old paragon transmission that I believe is designed to freewheel when sailing(Cascade 42 with perkins 4107). There is a pulley attached to the shaft that leads me to think that my boat was once so equiped.
I would like to do a few test to see the effect of linking a generator, how much speed lost vs power generated. Does anyone have an idea as to what size DC motor or generator I should be able to spin with a 19 X 12 LH prop. Also, what is the simplest (cheapest, least problematic) way to supply this power to the battery?

Any info on this subject is welcomed
