Hmmm . . .
Okay, the process is in place - but can it be economically scaled?
If "The ingredients are processed under high temperatures and pressures", where is the processing energy coming from? If the goal is a carbon neutral fuel, you're likely looking at solar or wind. But how efficient is the process? How much solar and wind is it going to take to produce blue crude? And at that point, it still needs to be refined.
The tree-hugging hippie in me would love to see this work, but the promise of fuel from water has been around longer than the myth of the 100 mpg carburetor.
Still, I think Audi brings a degree of credibility to this.
