If thousands of wind turbines are to be installed offshore, might as well get the most out of them. That's what Green Ocean Energy was thinking when it created Wave Treader, a wave power generator that attaches to a turbine's base.
The wave motion moves two floats attached to the wind turbine, pumping hydraulics that generate 500 kilowatts of power. Then, that power is transmitted to shore through the same cable used by the wind turbine. Now that's efficient.
The company plans to build a prototype this year, and plans to offer the devices for sale in 2011. We like the idea of wave power, and this makes it even more appealing. While they're at it, maybe they could also put some solar panels aboard each of those floats, for a tree-hugging triple play.
