Motor generator centerpiece delivered
The centerpiece of the SPARC motor-generator system has arrived at Devens. The second-life 685 MVA fossil unit successfully moved out of Constellation Energy's Boston Mystic Generating Station to the CFS campus. The generator will be used to convert stored mechanical energy in the world's largest 3600 RPM flywheel system into electromagnetic energy to drive fusion experiments at SPARC.
