IBM has unveiled a new supercomputer today that depends on water for cooling. The Power (or Hydro-Cluster) 575 provides five times the performance of its predecessor and reduces typical energy consumption used to cool a data center by 40 percent.
IBM scientists estimate that water can be up to 4,000-times more effective in cooling computer systems than air. The video below explains how IBM is trying to get the water as close to the chip as possible. More importantly, the resulting warm water can be considered a commodity to heat a building or a community pool. Cool.
