Audi claims it is closer to carbon-neutral cars

Already at the forefront of diesel technology with its current production cars, Audi is claiming a revolutionary step towards carbon-neutral cars after creating a new type of diesel from water and carbon dioxide.

Using renewable energy sources such as wind, wave and solar power, the water is split into oxygen and hydrogen. The hydrogen is then mixed with carbon monoxide, harvested from carbon dioxide in the atmosphere, and under high pressure and temperatures the two react to create crude.
