How this mechanical battery is making a comeback

What Exactly Is Flywheel Energy Storage? Flywheel energy storage is an advanced physical energy storage tech—and Honghui’s vacuum magnetic levitation flywheel systems take its functionality to the next level! At its core, it uses a high-strength rotor spinning at ultra-high speed (in a vacuum, via magnetic levitation) to store energy. When energy is needed, the rotor’s kinetic energy is converted back to electricity in milliseconds. Its standout functional advantages? Instant high-power output f
