Artificial Intelligence Companies Turn to Old Jet Engines to Power Their Data Centers The lack of electricity has led AI companies to use decommissioned jet engines to power data centers. After the restoration, these engines can provide the necessary electricity for these centers in about 24 months. SpaceXSI owned by Elon Musk is one of the companies that use this method. The company installed 8 refurbished GE jet engines in the state of Mississippi. These engines are supposed to play a role in supplying power to the Colossus 2 data center in Memphis.
