We have been so focused on chemical storage systems lately, that some us forget other old, seemingly more efficient, mechanical batteries. Such a battery is the flywheel. Several successful experiments have been carried out in the last 50 years, and the flywheel's applications ranged from acting as a UPS for a hospital to putting an entire train to movement and then to cruise speed, only by its power.
