Neat. I've never seen computing capacity quoted in watts, but it makes sense. The interesting part, or at least the part that hadn't occurred to me as possible/scalable, is how decentralized it all is. They must have some strong tech behind the scenes.
The one thing I wonder about is the physical security of the servers. At a big server farm, you would have things like backup generators, security guards and all that. But a server room at a heated municipal swimming pool?
