Tidal power
March 2nd, 2008 by Damon CliffordTidal power, sometimes called tidal energy, is a form of hydropower that exploits the movement of water caused by tidal currents or the rise and fall in sea levels due to the tides.
Although not yet widely used, tidal power has potential for future electricity generation and is more predictable than wind energy and solar power. In Europe, tide mills have been used for over a thousand years, mainly for grinding grains.

Tidal power works as I built 10 of them in the early 80′s to power cruising sailboats and worked so well they had to be turned off most of the time.
River power is even better as it’s more constant. My calculation figure out larger units can make power at $.01/kwhr for river and $.02/kwhr for tidal power. Between the 2 there is enough resource in the US for at least 20% of our electric needs.
