AI’s cooling crisis: Why future data centres in space may not need a single drop of water |

Artificial intelligence is driving an unprecedented surge in demand for computing power. Still, the data centres behind today’s most advanced AI models face a growing challenge: keeping millions of processors cool without consuming vast amounts of energy and water. On Earth, cooling systems can account for a significant share of a facility’s electricity use while…
