According to the U.K. Daily Mail, “Engineers at the entrepreneur’s Wiltshire HQ are developing a lightweight electric motor that could power a family saloon for hundreds of miles. The battery would be charged by solar panels mounted on the vehicle’s roof, or on the roof of a garage where the car is kept.”

“Sir James, whose inventions have made him a fortune worth around £800million, believes electric cars will outnumber petrol ones within a decade,” say the Daily mail.

Apparently the motor will be based on the same powerhouse used in the Dyson vacuum cleaners. Will that make the car a street cleaner as well?
