As reported by the BBC , IBM is looking for a solution. One idea is to cool computers the way the human body cools its brain — by using a fluid, i.e. blood. IBM’s Patrick Ruch and Bruno built a proof-of-concept computer chips that contains tiny channels that would circulate a fluid past electronic components, cooling them down. They think an electrolyte similar to what goes inside a battery would work best for the “electronic blood.” As it passed through the channels, it would not only dissipate heat, but would also deliver energy to the chips. It would work because as the fluid traveled through ever-smaller channels, it would pass electrodes that would pick up the electrons from the fluid and use them to create a current.
