In order to help boost their range, many electric and hybrid cars employ regenerative technology where braking energy is stored in the battery instead of simply being wasted. This idea can also be ...

Kinetic energy recovery systems have often been proposed as a useful way to improve the efficiency of on-road vehicles, and even used to great effect in motorsports for added performance. [Tom Stanton ...

Maxwell von Stein, a 22 year-old Cooper Union graduate, built a bicycle that uses a flywheel to store energy. Instead of braking, he can slow the bicycle by transferring the kinetic energy from back ...
