How the Chernobyl nuclear disaster led this woman to catch a wave

Inna Braverman

With wave power, it all seems pretty straightforward.

Waves come from the wind. Wind power is already a big-time clean-energy source (producing about 2.5 percent of the world’s electricity and growing). Water is 784 times denser than air, providing a lot more energy per cubic meter. Plus, people tend to live near coasts where the waves are: in the United States, for example, more than half the population lives within 50 miles of the ocean and all that potential energy.

It’s not straightforward. Complexities abound, ranging from where to site wave power installations (Offshore? Underwater? Free-floating or anchored?) to how to transmit the power they generate. And while not trivial, that’s the easy part. The hard part has to do with actually harnessing those wind-driven waves.

Wind blows in one direction, a relatively consistent, unidirectional power source, at least in the span of a few seconds. Waves are up and down and back and forth by nature. You can’t just miniaturize a wind turbine, sink it in the drink and fire up a toaster with water-born electrons.

So when Inna Braverman tells you that the company she co-founded — Tel Aviv, Israel-based Eco Wave Power — has come up with a really good way to harness those waves and fire up those toasters, know that it’s a big deal. [more]
