Re: Optimal propulsion system

Hello there, keep in mind that the Generators AC output changes with rpm in a very unfavorable way. Unfortunately changing rpm changes the AC volts, but most importantly hz. A modern generator needs to run at 1800 rpm's about 60 Hz. if you change the rpm you put the generator under undue strain, (windings in the stator) ( solid-state
voltage regulating system).Changing the RPM on a generator is very impractical. Whatever converts your AC to DC should operate at 60 Hz......Captg
