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...

Educators gain momentum from a model for continuous improvement "Good is the enemy of great. We don't have great schools principally because we have good schools." - James Collins in Good to Great, (2001, p. 1) On the eve of receiving...

The California Energy Commission (CEC) and the New York State Energy Research and Development Authority (NYSERDA) are both taking a step into the future by signing separate contracts with Beacon Power Corp. (Wilmington, Mass.) to demonstrate flywheel energy storage solutions (Figure 4) for frequency...

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...
