The product name is the Power 575. IBM is promoting is as a hydro-cluster supercomputer. To paint it green, the literature says the Power 575 requires 80 percent fewer air conditioning units and reduce total cooling costs by 40%. (It’s water-cooled).

Key points discussed at last visit to IBM:
1. Water cooling is 4,000 times more efficient than air cooling.
2. Air cooling has become too expensive and there’s a finite limit to how much power you can bring in.
3. It’s tough to budget ahead for air cooling – power costs are a big unfriendly variable.
4. Heated water is easier to recycle than heated air.
