How Does a Flywheel Store Energy? The Mechanical Battery Explained
When you think about energy storage, lithium-ion batteries probably come to mind first. But what if I told you there's a 6,000-year-old concept powering modern energy solutions? Enter flywheel energy storage - the original mechanical battery. Unlike chemical storage systems, flywheels harness pure physics: rotational inertia converts electrical energy into kinetic energy, spinning a massive rotor at mind-blowing speeds up to 160,000 RPM.
