95% Data-Center Cooling Energy Reduction Thanks to Fluid-Submerged Servers

All kinds of industrial machines and processes are liquid-cooled, but strangely, most servers in large data-centers are still air-cooled. This doesn't make a lot of sense now that cooling costs are often as high, if not higher, than equipment costs. One of the companies working on changing that is Green Revolution Cooling. They use a non-conductive white mineral oil that holds 1,200 times more heat by volume than air to submerge servers, leading to a 95% reduction in energy used for cooling and 50% reduction in total energy use.
