WASHINGTON (Reuters) -Alphabet's Google said on Monday it has struck a deal to buy power from a project in Virginia fueled by fusion, the reaction that powers the sun and the stars but is not yet commercial on Earth. Google signed what it called the technology's first direct corporate power purchase agreement with Commonwealth Fusion Systems, a company that spun off from the Massachusetts Institute of Technology in 2018. The deal is for 200 megawatts of power, about enough to power a small city, from CFS's ARC project that is being developed in Virginia, home to the world's biggest hub of energy-hungry data centers.
