Flybus is a funded project to build a cost-effective alternative for battery-hybrid buses by UK’s Technology Strategy Board for Low-Carbon Vehicle Initiative. The idea is absed on the use of flywheel kinetic energy storage system, once the bus decelerates, and claims capable to save up to 20 percent in fuel consumption as well as reduction on CO2 emissions during city operations.
Flybus’ energy, is derived from wasted heat, and is stored in the flywheel, spinning at speeds of around 60,000rpm. Once the vehicle’s engine active again, the CVT returns the energy from the flywheel to the bus, ensuring that load on the engine is reduced and so is fuel consumption. During this process, the flywheel gives up energy and slows down until the next vehicle deceleration.
So much for the kinetic energy, wonder when the passengers’ kinetic energy or heat would as well properly used for powering up green busses? :p
