INTRODUCTION:
1. A Gyrobus is an electric bus that uses flywheel energy storage, not overhead wires like a trolleybus.
2. The name comes from the Greek language term for flywheel, gyros. While there are no gyrobuses currently in use commercially, development in this area continues.
Advantages:
1. Quiet
2. "Pollution-free”
3. Can operate flexibly at varying distances
Disadvantages
1. Weight: a bus which can carry 20 persons and has range of 20 km requires a flywheel weighing three tonnes.
2.The flywheel, which turns at 3000 revolutions per minute, requires special attachment and security—because the external speed of the disk is 900 km/h.
