Water usage?

Water usage? I would assume for a lot of centers this could be zero -- I mean, my car uses water cooling but the coolant is not shot out onto the ground when it's done cooling the engine. I would have thought most cooling loops would be a loop -- you put the water in once and it recirculates. I would also think data centers that are open are set up so they pull in water, heat it up some, and spit it back out into whatever water source they got it from. Which of course is a concern insofar as if the river or lake level drops, they then have intake pipes stuck up in the air instead of underwater, but would still yield net 0 water usage.

That said -- this is in everyone's best interests all around. I'm waiting with baited breath for ARM desktops and notebooks (besides Apple) to come out so I can enjoy reduced power use at home and better battery life and lower heat production on my notebook (I had a Chromebook with Tegra K1 and it was awesome -- faster than my desktop at the time, I set it to boot into Ubuntu and got 22 hour battery life in Ubuntu -- and still just over 12 hours if I ran the quad-core ARMs full-tilt running video encodes! But it was certainly engineered to spec, the case, power connector, battery, keyboard, and trackpad crapped out within like 2 weeks of each other after about a year and half of use.) Besides environmental reasons, power and cooling are large costs for data centers so anything that reduces these usages reduces their costs as well.
