Right. "Oh what a wonderful world" it would be if all the power you needed was "free", but with the number of people we have, and will have, that's never going to happen, and if it ever does it's not going to happen anytime soon. Plus, now there are lawsuits against wind farms, because they are killing eagles. We need a good ol' fashioned plague. What was the number of people needed to populate another planet (an article a few weeks ago)? 10,000 to 40,000? Sounds good to me.
