Renewable Energy Source.. Inspired by Fish

An array of VIVACE converters on the ocean floor

“An engineer in the US has built a machine that can harness energy from the slow-moving currents found in oceans and rivers around the world. By exploiting the vortices that fish use to propel themselves forward, the device could, he says, provide a new kind of reliable, affordable and environmentally-friendly energy source.

Turbines and water mills can generate electricity from flowing water, but can only do so in currents with speeds of around 8–10 km/h if they are to operate efficiently. Unfortunately, most of the currents found in nature move at less than 3 km/h. The new device is called VIVACE, which stands for vortex induced vibrations for aquatic clean energy, and its inventor claims it can operate in such slow-moving flows. “

Interesting read, but personally I am skeptical this would ever be used in mass.
