A Chinese farmer has invented a wind-powered electric car that he says could save his country from the pollution caused by its rapidly growing car market. An hour from Beijing, the dusty village of Banjiehe looks an unlikely place to produce scientific innovation.
Its rows of brick, utilitarian houses are surrounded by cornfields and fruit trees. But in a small tractor workshop, 55-year-old farmer Tang Zhenping has invented the prototype of a car that he believes could revolutionize China's auto industry. Mr Tang's model - built in just three months for around �1,000 - is electric.
Its engine uses scrap parts from a motorcycle and electric scooter, while its steering wheel, upholstery and headlights all come from a Chinese-made Xiali hatchback. But what makes the one-seater special is the turbine on its nose.
When the car reaches 40mph, the blades spring into action and begin generating pollution-free power. "It works just like a windmill," said Mr Tang, who claims the turbine gives his vehicle three times the battery life of other electric cars. The model has a top speed of 70mph.
