Flywheel Energy Storage Modules (FESM) could replace batteries on Earth-orbit satellites. • While in sunlit orbit, the motor will spin the flywheel to a fully charged speed – generator mode will take over to discharge the flywheel and power the satellite during the eclipse phase – present flywheel technology is about four times better
