Today’s processors are fast and hot. Hot enough to scramble an egg or two on them. Bell Labs, still the king of breakthroughs has come up with “Nano Grass,” or tiny tubes which spray cooling liquids on the chip to cool it down. It is a system much like the liquid cooling systems in the cars these days.
bq. To solve the problem, a chipmaker would plant nanograss on the walls of micro-channels etched on the chip’s surface. That way, liquid would be applied only on the hot spots, with the excess flowing through the channel to a radiator sitting on top of the chip, so it can be cooled and reused.
