This approach has proven very efficient at transferring energy, says Mr Elsy.Finally, despite their assorted advantages over battery-based KERS, flywheels do have some drawbacks.
Flywheels, by contrast, merely turn one sort of kinetic energy (of the wheels) directly into another (of the flywheel), which is far less wasteful.Moreover, unlike batteries, which need to be replaced every few years, flywheels are designed to last the lifetime of the vehicle, and contain no nasty chemicals which need to be disposed of.
