- What will it cost? Estimates are coming in at about 5.5 cents per kilowatt hour. When compared with nuclear (4.6 cents a kilowatt hour) wind (6.9 cents a kilowatt hour) andsolar (16 to 48 cents a kilowatt hour) Vivace looks like a serious competitor.
- Most of the water that covers 70% of our planet flows at less than 3 knots - too slowly to harvest its power using current technology. Wave and tidal turbines require an average of 5 or 6 knots to operate efficiently, as does the timeless watermill. ButVivace, the technology being developed by Dr. Michael M. Bernitsas at the University of Michigan, is designed to operate at currents of less than 2 knots, opening up a world of possible applications from river power and dam replacement to perpetually powered ocean sensors, uninterruptible power for vulnerable coastal facilities, and the supply of electricity to offshore facilities.

- “The muscle power that fish have is not enough to support the speed at which they’re going,” says Bernitsas, a professor of naval architecture at the U. of M. “So, if you study more carefully, there are lots of things going on. A fish will curve its body, collect a vortex, shed it, and collect one on the other side and shed that, alternating on the two sides of its body.”

Shockingly simple low speed renewable energy source
Extract energy from rivers as slow as 1 kph. Testing in the Detroit river. Now this is an idea! Just make it BIG. Finally, vorteces are your friend.
