I'm working on a solar power system and expect to hit 8-12k rpm on a steam driven turbine. I don't know how much torque I will pull but I'm guessing not much. What would be the best generator to use to take advantage of the high RPMs in order to push the most power to my battery storage? Would a flywheel and capacitor system offer any advantages without pushing the cost too high? I'm hoping to be able to generate a great deal of energy based on the high rotation - were this a low RPM wind system I know the best motors to use for generators.
