Berkeley Engineers Catch Waves for Clean Energy

If you’ve ever been knocked over by a breaking wave, you’ve felt the ocean’s power, but did you ever imagine it could be turned into electricity?

According to the U.S. Department of Energy (DOE), waves, tidal currents, and thermal gradients along American coastlines could potentially generate some 2,640 terawatt-hours (TWh) a year. That’s more than half the total U.S. production—enough to power as many as 200 million American households—emissions free.

Mass Appeal: Researchers Score Public Support—and Cash—Via Crowdfunding

Marcus Lehmann is at work alongside a 50-meter-long water tank in a high-ceilinged engineering lab at UC Berkeley’s O’Brien Hall, surrounded by wrenches, tape, wires, electronics, pipes, lab notebooks and other flotsam and jetsam. Within the tank, he generates ocean-like waves to test a promising invention: a carpet-like device that captures wave energy. It holds the promise of someday being able to harness the power of the ocean, a potential huge source of renewable energy.
