Bio-Diesel
What did you think of those chemical engineers in Nevada making bio-diesel from Starbucks coffee bean residue? They claim they can make 840 or so million gallons a year from them. That may not be the exact amount but it was a lot. I guess, there is no end to the possibilities!

Bet the cars will run like faster on Starbucks than on anything else -- I want my engine caffeinated....

A 'link' to this story would be nice, so we can post our thoughts...googling is not as user-friendly as it used to be.

I always get heart palpitations from Statbucks. I never feel right on the stuff...
Can't imagine what my 25 year old car would do on it. |

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.

The biggest difficulty I could see in doing this is that the grounds wold have water in them, so as you press the oil out, you're going to get a lot of water with it. Then you'd have to separate the oil and water. Not a really big deal, since people regularly do a water wash of the finished product and settle the water out of it anyway. Just adds one more step to the process.
I wonder how many pounds of grounds the average store goes through per day or week? The article says the grounds are 15% oil - presumably measured by weight - so if they were going through say 100 pounds a day, that's 15 pounds of oil - about 2 gallons. 7 days a week = 14 gallons a week of oil that could be extracted from their waste grounds. If a guy had a press handy, that might be worth the effort, given that wvo has become so hard to find these days. Unfortunately, building or buying a press would probably be way to costly of an "extra" expense to make it worthwhile for the average Joe to make bio from Joe... |
can you emagine the exhaust smelling like french Roast instead of
French fries? Charlie |
I can imagine the idea of new "smells" being concocted.
Either it will give your diesel a little extra caffiene pep or the runs. This might depend on the "age" of your car. Hmmm...... I wonder how MB diesel benz years compare to human years with regards to aging. |
