You're joking, but enough of these things to generate a significant amount of power, when located in deep water, would be a serious hazard to navigation.
In the late 60's early 70's Offshore Power Systems, I believe a div of GE, was going to build floating Nuclear power plants off the coast of Jacksonville FL, but I think the Enviro Nutcases got it killed before it was ever off the ground (or on the water)...........
You think THATS bad, what about the birds?
It was Westinghouse, not GE..........see link for more info......
