Hybrid Bicycles May One Day Power City Buses


In the future, tiny bike and the hulking city bus -- currently mortal enemies -- may actually be on the same team.

Designer Chiyi Chen's Hybrid2 bike concept is intended to allow the human energy exerted on rented bikes to power fleets of city buses, sans fuel. Essentially, the hybrid rental bikes would work much like hybrid cars: a regenerative braking system would preserve energy for later use. But in this case, said energy wouldn't be used to power the bike. The electricity stored on the bike would be downloaded back into the energy grid later, where it would provide power to the hybrid bus system.

Another nice detail: users would have a special RFID card to keep track of who was using which bike and to monitor each rider's energy savings -- those able to build up enough credit could ride the bus for free.

It's folks like Chen who are going to save us from eating ourselves one day. Bravo. [From: Engadget]
