Main Question or Discussion Point
Is it possible for electric motors to compare to the strength of human muscles, in terms of power-to-weight ratios? That is, with the proper engineering, is it theoretically possible? I don't see why not, simply increasing voltage increases power, if the heat generated is a problem, can't the motor be engineered to withstand the temperatures? Or does it have something to do with how muscles can vary torque/speed at will but motors can't?
