Battery-sized car

Feng Yue Sheng (center) holds up a silicon power battery he invented, while seated in an electric vehicle at an Eco-Expo Asia show in Hong Kong yesterday. The car uses four units and boasts a mileage per vehicle of over 200 kms and a track speed of up to 80 km/h with an 80 percent battery charge that can be reached within 20 minutes. The Eco-Expo Asia has been partly sponsored by the Hong Kong government to promote a green theme in the city.
