Hydrokinetic turbines operate from underwater currents, whether from rivers or tides. We applied computational fluid dynamic technologies to underwater river and tidal turbines. The result was a turbine based on two synergistic patents, one on shroud shapes and the other on blade shapes.

Pioneer Valley Renewables LLC uses two complementary patents to make improvements in the effectiveness of underwater turbines of 50-300%, depending on the size. The market is for what is called “hydrokinetic” power, which includes both rivers and tides. The technology has already been confirmed theoretically by US Navy engineers.
