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 downtown 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 revolutionise 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.
