Gyrobus: The Flywheel-Powered Public Transportation

The flywheel that was used was rather large (160 cm diameter) and heavy (1.5 ton) and was enclosed inside an airtight chamber filled with hydrogen gas at reduced pressure to lower resistance. Recharging the flywheel from standstill took up to 40 minutes, but once spun, adding additional energy to the flywheel took as little as two to five minutes.

The Gyrobus : public transportation using flywheel energy

The technology uses an electric engine powered by a large flywheel, weighing 1500kg (one flywheel). Once the flywheel is launched, its kinetic energy is converted into electric energy and supplied to the propulsion engine. During passengers'' ascent and descent, the flywheel is reloaded, then put back into rotation.

Gyro bus | PPT | Free Download

A Gyrobus is an electric bus that uses flywheel energy storage, not overhead wires like a trolleybus. The name comes from the Greek language term for flywheel, gyros. The name comes from the Greek language term for flywheel, gyros. 3. • The concept of a flywheel- powered bus was developed and brought to originality during the 1940s by

Study on Rollover Prevention of Heavy-Duty Vehicles by Using Flywheel

Until recently, the flywheel energy storage system was loaded on a vehicle with a double gimbal support device to avoid a bad influence of the gyro effect on the motion of the vehicle. However, the flywheel energy storage systems have to be supported by single gimbal to use gyroscopic effect of the flywheel for rollover prevention.

It operates by rapidly accelerating a rotor and retaining the energy in the system as rotational energy. Flywheel energy storage has great promise as an alternative to traditional lead-acid batteries. In addition to the gyro bus, NASA''s G2 flywheel for spaceship energy storage also utilized the flying wheel.

Gyroscope Active Precession Drive

Green Energy Flywheel Energy Storage. The periodic power demands of driving and braking are met by utilising the gyroscope rotor as an energy storage flywheel. Gyro Marine''s intelligent controller utilises the significant kinetic energy of the rotor to provide periodic power to drive the precession and then returns the energy derived from

Bearings for Flywheel Energy Storage | SpringerLink

Bearings for flywheel energy storage systems (FESS) are absolutely critical, as they determine not only key performance specifications such as self-discharge and service live, but may cause even safety-critical situations in the event of failure. Looking at the gyroscopic torque response of the gyro (FESS) to the deflection in Fig. 9.15, it
