Turbines

In a turbine design, water comes down the hub and move out to the vanes, setting the wheel turning. The faster the wheel turned, the faster the water would be thrown out against the vanes, delivering far more power and speed than an ordinary waterwheel. An initial design generated 6 hp, but within a few years he produced 50 hp.
