Clean Energy from Slow-moving River Currents
VIVACE (Vortex-Induced Vibrations for Aquatic Clean Energy) invented by Mike Bernitsas, director of the Marine Renewable Energy Laboratory at the University of Michigan, is a device to harness energy in slow-moving water currents across the globe and turn it into electricity. Unlike water-driven mills, turbines or dams, VIVACE doesn't require fast-moving water _ most streams on the globe are slow-moving _ and doesn't harm the environment.
The envision is groups of cylinders in frames on the ocean bed or in streams, perpendicular to currents. As the water flow hits the cylinders, it creates vortices that cause the cylinders to move up and down. That energy drives generators to make electricity, which goes through cables to the electrical grid on land. The size, number and placement of the cylinders depends on the body of water.
