Just a quick question. Are there any other methods of propulsin that come from electricity other than electromagnetic (like in motors), ion, or electrokinetic? None of them are incredibly effecient asfar as I know, except for those lego dacta motors. You hook up one motor to the other and spin one like a generator, the other will spin just about as fast. Close to 100% effeciency. Now how to make them bigger?
