Not going to spend the time to do the research, but I would venture a guess that Lake Anna in Va is there because of the Nuke.
Assuming the water is unsafe due to heat....(which I disagree with as I too have be in the lake in the summer) there are other things one can do with the lake...fish, warm water makes bigger fish as they can eat longer in the season, views from milliion dollar homes and docks.
On the way back from Pittsburgh today, I saw 7 windmills...not one was spinning. The last time I drove by, 2 were spinning. I would love to see the return on actual investment on those mills thus far....true cost, cost of land, construction, permits, maitencence, depreciation etc.
