Vortex Hydro Energy has exclusive license to commercialize a University of Michigan patented, hydrokinetic power generating device, the VIVACE converter, which harnesses hydrokinetic energy of river and ocean currents. This converter is unlike water turbines as it does not use propellers. VIVACE uses the physical phenomenon of vortex induced vibration in which water current flows around cylinders inducing transverse motion. The energy contained in the movement of the cylinder is then converted to electricity.

The VIVACE converter is a transformational technology. It taps into a vast new source of clean and renewable energy, that of water currents as slow as 2 to 4 knots previously off limits to conventional turbine technology that target rivers with water currents greater than 4 knots. The vast majority of river/ocean currents in the United States are slower than 3 knots.
