Taking Offshore Wind Further

Turns out our entire civilization could be powered by the winds over the open oceans.

Of course, there's a number of problems with this:

1. We'd need to cover an area the size of Greenland with wind turbines.

2. We don't have the technology to build wind turbines right out in the open ocean.

3. It would cause, yup, more and different climate change.  Harvesting that much power would affect wind speed, temperature, etc.

So we can't actually do it.

Yet.

(Oh, as a side note, if you saw the stuff about how Yellowstone is going to erupt again and we might not get much warning - no, the tabloids are wrong, Yellowstone blowing its top would NOT destroy all life on Earth. It has never triggered a mass extinction before. It would cause economic problems, particularly for the US, and probably a few years of not much in the way of summer, but it wouldn't destroy all life, our species or even our civilization).
