Bubble-recoil could be used to cool microchips, even in space

The bubbles that form on a heated surface create a tiny recoil when they leave it, like the kick from a gun firing blanks. Now researchers at the University of Illinois at Chicago, under funding from NASA, have shown how this miniscule force can be harnessed to mix liquid coolant around high-power microelectronics — in space or on Earth.
