Who remembers google's patent from a couple of years ago for floating data centers? Using the sea to cool it was a big part of that idea, alongside tidal power. I'm kinda disappointed to see that this isn't the complete realisation of that stuff, but its still a move in the right direction.

I wonder if you could start a tropical reef around the outlets?
