CNN has a great article on the idea of floating wind turbines father out in the ocean. In the United States the first of its kind will be set up off Maine's coast. It is one of an array of 10 that are planned. And it is 20 miles from the land, so people can't see it (a traditional complaint).
I confess, until I saw this illustration I was skeptical. Honestly, I thought that floating windmills would just fall over. Which is silly because we can do oil wells that deep.
Turns out that farther off shore we are working on various ideas to capture wind. And the promise is that in these reliably windy areas we can create a HUGE amount of power. Its a cool idea.
