A device developed by Michael Bernitsas, a professor in the Department of Naval Architecture and Marine Engineering, can harness energy from slow moving ocean and river currents. The machine is called VIVACE. It could open the door to a new, reliable and affordable alternative energy source.

Bernitsas calls the machine "fish technology." It borrows from the swim strategy of a school of fish to turn potentially destructive vibrations in fluid flows into clean, renewable power.

VIVACE stands for Vortex Induced Vibrations for Aquatic Clean Energy. 

In cooperation with the Detroit/Wayne County Port Authority, a recent feasibility study showed that VIVACE could indeed harness power from the Detroit River. A pilot device will be installed in the river in early 2010.
