Giant offshore windpower

Gizmag and Science Blog write about a really cool idea: giant floating wind turbines located offshore. Advantages:

• Bigger is much better for wind power, and these can be huge.
• More wind is much better for wind power, and there's lots more wind on open sea than on land.
• They are not fixed, so can be towed to where power is needed.
• They would be far enough offshore that nobody can see them from shore.
• All of the usual wind power benefits (relatively cheap, no pollution, no greenhouse gas, no peak oilfossil fuel, not controlled by klepetro-states...)

This idea needs to be implemented ... full force!
