In London, Demis Hassabis soon revealed that DeepMind had built a system that reduced power consumption across Google’s9 network of data centers, drawing on the same techniques the lab used to crack Breakout. This system decided when to turn on cooling fans inside individual computer servers and when to turn them off,10 when to open the data center windows for additional cooling and when to close them, when to use chillers and cooling towers and when the servers could get by without them. The Google data centers were so large and the DeepMind technology was so effective,11 Hassabis said, it was already saving the company hundreds of millions of dollars. In other words, it paid for the cost of acquiring DeepMind.
