Audi recently announced it has invented a new diesel fuel that could revolutionize the automobile industry and dramatically reduce carbon dioxide emissions. Even more remarkable, the synthetic ‘e-diesel’ is made with water, CO2 and electricity derived from renewable sources of energy. Run by a company called sunfire, whose tagline is ‘closing the carbon cycle’, a new pilot plant in Dresden churned out its first 42 gallons of CO2-neutral fuel. The ‘blue crude’ has successfully powered an Audi 8 belonging to Germany’s Federal Minister of Education and Research, Johanna Wanka. Curious? Hit the jump for more details and a video.
