"There's much talk of wind and solar power. But how about the oceans and their massive tidal and current patterns? Driven by the gravitational force of the sun and the moon, tides and currents represent a source that's as infinite and everlasting as any force on earth.

A major pilot demonstration seems ready to launch in San Francisco Bay, where an immense tidal flow enters and exits every day at a narrow point of the Golden Gate. A gigantic energy-collection device vaguely reminiscent of a Ferris wheel, with a number of fins (or ''wings'') to capture the power of the rapidly passing tides, will be lowered from a barge anchored in the narrows. Using maglev technology, it will produce electrical energy that can then be transmitted to shore by cable."
