Not a bad substitute for 80-octane fuel and dirty mazot. Riversimple, a small independent car manufacturer in rural Wales, have got their hopes up that hydrogen vehicles can play a vital part in the future of transport. Dubbing their handbuilt car Rasa, the aerodynamic two-seater weighs just 580 kg. Each of the car’s four wheels has a motor, powered by hydrogen running through a fuel cell. When the hydrogen combines with oxygen it produces electricity to power the motors, with water as a byproduct, according to CNN. The car apparently only takes three minutes to refuel, has a range of 500 km and a top speed of 96 km/h.

The catch? “Until the refueling infrastructure exists for hydrogen, then it will always be a bit part player compared to battery electric.” Riversimple will run trials for 20 Rasa vehicles in Monmouthshire early next year (watch, runtime: 3:38).
