VIVACE

Vivace stands for Vortex Induced Vibrations for Aquatic Clean Energy. Slow-moving ocean and river currents are reliable and affordable alternative energy source. Vivace in a machine that works like a fish to turn potentially destructive vibrations in fluid flows into clean, renewable energy. Michael Bernitsas, Professor in University of Michigan, Dept. Naval Architecture and Marine Engineering developed Vivace. Electricity created with Vivace is cheap: 5 cents per kWh compared to wind costing 6.9 cents per kWh, and with nuclear power costing 4.6 cents per kWh. Of all the alternative energy technologies solar is the most expensive: 16 – 48 cents per kWh. According to Benitsas, if we could harness 0.1 per cent of the energy in the ocean, we could support the energy needs of 15 billion people.
