Enrico Fermi. Flywheels store kinetic energy (energy of motion) by mechanically confining motion of a mass to a circular trajectory. The functional elements of the flywheel are the mass storing the energy, the mechanism supporting the rotating...

A heavy wheel attached to and revolving with a shaft in order to regulate its rotation within...

A flywheel is a rotating disk used as a storage device for kinetic energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a...

Everyone from Cameron Diaz to George W. Bush (now there's a dichotomy for you!) is talking hybrid cars. Are these dual-power gasoline-electrics really economical? Really environmentally sound? Really high-tech? Really fashionable? All of the above? None of the above? Or some combination of the above? To...

Like the Bonneville Salt Flats, One Lap of America is a speed-freak playground for aftermarket engineering. Sure, there are always a few cars that could be perceived as factory-supported, although sometimes this perception requires some squinting. We exclude press-fleet cars, such as the C/D BMW...
