University of Michigan makes power out of slow water currents

Here's a cool video from the University of Michigan about a device called VIVACE that derives energy from slow water currents. This new renewable energy technology, developed by University of Michigan researchers, can make energy out of slow currents in the ocean and rivers. This is a great way of tapping into new vast energy resources, as the great majority of all water currents worldwide are under 3 knots, Professor Michael Bernitsas explains. Even a water current as slow as 1 knot can be tapped for energy
