Experimental wave power buoy achieves power production in offshore tests

Those who accuse the green movement of failing to provide tangible results should look no further than energy technology developer Neptune Wave Power's Wave Energy Conversion (WEC) system. This machine was recently tested off the coast of New Hampshire at a Center for Ocean Renewable Energy site and, according to an announcement published on October 18, has cleared the objectives in two separate testing exercises.

The WEC device utilizes what is known in the clean power community as a "point absorber." This means that the buoy is chained to the ocean floor, and as the ocean rises and falls during wave activity, the kinetic energy that is created is captured and then transferred to the shore.

There is another component that makes the buoy unique among water-based renewable energy sources, however. Installed inside is a horizontal pendulum that is activated by the sea's motion. Unlike wind mills or similar systems, the pendulum does not require movement in a certain direction in order to generate electricity.

So far, two models have been tested by Neptune Wave Power. The latest one incorporated several improvements, including remote weight adjustments, wireless programming maintenance and a hull designed with mass production in mind.

"Our goal is to deliver energy by creating the most robust, maintainable, and economic system possible," Steve Hench, a principal researcher for Neptune Wave Power, said in a statement. "We are optimizing energy extraction from ocean waves through a tunable system that reacts to a wide range of sea states. The tests have been very positive."

The testing of the WEC could be the start of a movement that leads to seaside towns and cities being able to power their homes and buildings with renewable energy sources. Until then, keep an eye out on the coast for one of these up-and-coming clean power devices.

  1. Mr. Michelson,

    Your article is nice but I’m curious about where you obtained my job title of “a principle researcher.” I am the inventor, founder, and Chief Scientist. Would you be able to correct your content?

    Thank you,
    Steven C. Hench
