Microsoft's Big Bet on Fusion Power from Helion by 2028.

Microsoft has signed a power purchase agreement with nuclear fusion startup Helion Energy to buy electricity from it in 2028. The deal is a notable vote of confidence for fusion, which holds promise of being able to generate nearly unlimited clean power, if it can be harnessed and commercialized on earth. Helion's deal with Microsoft is the first time a fusion company has inked a deal to sell electricity. Helion was founded in 2013 and currently has about 150 employees, with headquarters in Everett, Wash.
