Next time you hop on a bus in Hong Kong, it could be as green as a walk in the park.
Dubbed the 'gBus' for green and genesis, Kowloon Motor Bus (KMB) is currently trying out a bus that it claims emits zero emissions because it runs on electricity.
The company plans to introduce the model to its fleet within a year.
KMB has leased the bus from a company in Shanghai for six months to see how it takes to local roads.
Kane Shum, principal bus engineer with KMB, said the bus runs on a super-capacitor system, which has several advantages. It can be recharged in short bursts at regular intervals without damage to the battery and it does not rely on chemical reactions to store electrical energy.
'It also runs on an anti-current system so every time the bus driver brakes, it builds up the battery,' he said.
