Tesla patents ‘Electric Fan Car’ with 4 ducted fans ahead of Roadster reveal

Tesla was just granted a patent for an “Electric Fan Car,” a system that uses four electric ducted fans in the rear diffuser to suck the car down to the road at any speed. The car in the drawings is a Model S, which Tesla stopped building in April. It’s Tesla’s second fan car patent in just over a year, and it arrives two weeks before the company’s latest attempt at a Roadster demo.
