You don’t need 60 hp. All you need is a wheel to turn a 60 inch pulley at 60 rpm belted to a 1 inch pulley giving you 3600 rpm which is enough to turn a 40 kw generator. Remember, a pulley can be made out of wood. As a matter of fact, the old sawmills had wooden pegs on the wheel that worked as sprocket teeth turning another but smaller horizontal wheel with
wooden pegs and so on to get the 36 inch circular saw blade to turn at around 3000 or so rpm.
