I refer to recent articles and a letter from Anders Ejendal (“Idling engines in Repulse Bay“, April 19), regarding idling engines. I wish to point out that all vehicles, including coaches, can enjoy air-conditioning while stationary without their engine running.
As an electric vehicle designer, I can assure everyone that all these petrol/diesel coaches require is an extra supply of battery power and some smart electronics, and this is not expensive. For example, most taxis can have a workable system installed for around HK$10,000.
Replacing old air conditioners with hi-tech ones will enormously reduce electricity needs. Technology is available to convert any coach to fully electric drive, and it is an economically viable proposition.
