I am wondering if this can have any negative ecological side-effects. I know a large issue with nuclear powerplants was them using local rivers for cooling. In the end, they raised the temperature of local lakes enough to make algae produce less oxygen, fish be wiped out, and overall adversely effect water life. If you put enough of these in close proximity (the wake/wind 'sweetspots'), can they potentially heat up their surroundings enough to make a difference? I understand the ocean is a different beast from lakes, but if you can heat up a square mile, that's a lot of sea life existing in that mile. As quoted, 40MW of power is not exactly little heat.
