FollowLike most renewable energy sources, ocean waves cannot compete with the low costs of fossil fuels. It’s expensive to get wave-generated electricity ashore and add it to a local grid. But what if wave-energy conversion could be used where it’s generated?
The U.S. Navy aims to find out. A few weeks ago it installed a system of what are called PowerBuoys, made by Ocean Power Technology. The buoys are bobbing in the Atlantic about 30 kilometers off the New Jersey coast. Each one contains hydraulic fluid and a generator.
