Old trawler now harvests wave power instead of fish
• http://www.gizmag.com, By Ben CoxworthThe project is being led by Norway's Kvernevik Engineering AS, although the concept for the fishing boat conversion was first developed by Geir Arne Solheim, founder of wave power company (and project partner) Havkraft AS.
The vessel incorporates an existing system known as the "fluctuating water column" concept. It has four vertical chambers installed in its bow, which the surrounding sea water can flow in and out of. Each chamber is capped by a connected turbine, located on the boat's deck.
As waves hit the vessel, they flow up into the chambers, causing the water level inside each one to rise. This in turn causes the air pressure in the top part of the chamber to increase, thus driving the turbine and generating electricity. Likewise, as the water flows back out of the chamber, the lowered air pressure sucks air in through the turbine, again causing it to spin.
