Audi Uses Water and Air to Make Cleaner Fuel for Cars

Audi has revealed that it has managed to use water and air to create its own synthetic diesel fuel, or liquid “e-diesel,” as an alternative fuel source for cars. The German automaker worked with clean technology company Sunfire to create the fuel at its plant in Dresden through a “power to liquid” process that uses carbon dioxide, according to CNN. Carbon dioxide, created mostly through the burning of fossil fuels, is the most common of greenhouse gases and is a major contributor to global warming.
