In theory the water stays clean and can be reused. But I assume these cheapskates will go for evaporative cooling everytime? Then yeah, we need laws against that.
I keep hearing people claiming that water is just as much as issue as energy for operating these DCs, but that just doesn't make any sense to me. However, I haven't had to step inside a DC for almost two decades.
I guess when you're dissipating upwards of a gigawatt of power at a single site boiling water starts to look attractive. It's a pretty impressive curveball; I definitely would never have predicted "an evil corporation boils off all the local drinking water" to be a legitimate concern. I'm pretty sure that's too absurd a plot point for even a children's movie.
