A couple of months ago, I ran into a guy in the parking lot of a local grocery store who was curious about my car (was driving the 250 that day). After I mentioned I had a couple of Mercedes diesels and was using biodiesel in them, he told me about his work on that very project. I was a bit skeptical of using old coffee grounds to make fuel, but he was quite enthusiastic. At that point they had already made a few small batches.
