This Riversimple Urban Car (RUC) is powered by fuel cells. These fuels cells combine hydrogen with oxygen from the air to release energy. What comes out from the exhaust pipe is not toxic fumes but water. Even using hydrogen fuel from source to car’s fuel tank, its carbon emissions for urban driving are only 30 grams/km. The weight of this hydrogen car is 772 pounds. You can travel 186 miles on just 2.2 pounds of liquid hydrogen. The Riversimple Urban Car is powered by a cheap, 6-kilowatt fuel. The car's top speed is 50 miles per hour (80.4672 kilometres per hour). It can be accelerated from 0 to 30 mph (48 km/h) in 5.5 seconds.
