What use would there be for a perpetual motion machine? As soon as you tap the energy from it, you unbalance its cycle and remove to energy needed for its continuous motion.
The site looked nice, until the word “perpetual” came up. You don’t have to be a physicist to know there is no such thing. I’d say, you should look into turning this into a better way to harness the power of rivers and the like, rather then to try building the impossible machine.
