Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th…

It''s called flywheel energy storage, and Walkingshaw — a Utah entrepreneur — created a company called Torus to sell the device to store solar and other renewable sources of energy. "I had no idea that I would have ended up in energy storage at all," said Walkingshaw, who was previously the chief experience officer of Pluralsight.
