BM and the Swiss Federal Institute of Technology at Zurich plan to build a water-cooled supercomputer whose surplus heat will be re-used to heat the university's buildings. The machine will re-use heat directly for in-building heating. IBM estimates that the water-cooling scheme will reduce the system's carbon footprint by up to 85 percent and save up to 30 tons of carbon dioxide annually, compared with standard cooling approaches.
