One last addition to this idiotic water idea.. since the water doesn't get up there to the reservoir on the roof by itself, add your costs of huge pumps, plus the cost of pumping it up there, and a less than 100% efficiency in converting falling water to electricity. Also, add heating it in the winter to keep it liquid instead of solid, decontamination chemicals (cant have any Leigonella bacillus growing in there in the summer) Its all moot, as the weight factor makes this a non-starter.
Nah, you just have to think about placement; find a convenient reservoir, dig a big hole in the stone to one side of the dam, and put your datacenter there. now, about that anti-flooding insurance.... :)
