IBM Supercomputer Cooled With Hot Water 89
1sockchuck writes "IBM has deployed an innovative supercomputer cooled by hot water in a Zurich computer lab. The Aquasar supercomputer employs a chip-level liquid cooling system that can use water at temperatures as high as 60 degrees C (140 degrees F), and as a result consumes up to 40 percent less energy than a comparable system using room-level air-cooling. The system also uses waste heat to provide warmth to buildings, reducing Aquasar's carbon footprint even further."

No, a souped-up computer.

I don't understand. The temperature difference is higher than what? Higher than it would be for even colder water? That doesn't sound right.
The bit about why hot water freezes faster made sense to me.

IBM is very good at making non-leaking water hoses. I wish Sears would license their technology.

Hot water doesn't freeze faster.
Sometimes, it does [wikipedia.org].
