Re: Build somewhere else?
Unfortunately they won't be able to heat the water enough for this to be useful - data centre cooling is about taking heat away quickly from the hot chips, not letting the water stay there long enough to reach a high temperature. What's really needed is cooling towers so that most of the water could be reused. But there's currently no economic incentive for this at the moment - they would probably needed to prodded into it by charging large enough amounts for the water to make it economical to do so.
