University of Michigan Invention ( Solar Thermal Magazine) – This device called VIVACE developed at the University of Michigan draws power out of slow water currents to produce clean electricity. It imitates the swim strategy of a school of fish.
It was first developed back in 2008 so I wonder if it ever made it off the drawing boards. It is being developed for U of M by Vortex Hydro Energy. Here is the video from U of M.
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.
Here is an update from 2013.
