Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

A few pre-race notes and a lot of photos from the 24 Hours of Le Mans

The 82nd running of the 24 Hours of Le Mans is on.
Audi has won 12 of the last 15 events, the scion of Auto Union is trying to make it 13 this year. To do so, it will have to overcome a situation faced only three other times during its dominance of La Sarthe: underdog status. Toyota has won the first two races of the year and claimed pole for this race, the rumor being that this year it's Toyota's race to lose.
And then there's Porsche. It's been 16 years since the Stuttgart brand raced on the top rung at Le Mans, three years years since it announced its return, just a year since it acquired Mark Webber in a signing that wasn't subtle and a few months since we got eyes on the 919 Hybrid.
