Waste Coffee Grounds Offer New Source of Biodiesel

Julie188 writes "Researchers in Nevada are reporting that waste coffee grounds can provide a cheap, abundant, and environmentally friendly source of biodiesel fuel for powering cars and trucks. Their study has been published online in the Journal of Agricultural and Food Chemistry. Growers produce more than 16 billion pounds of coffee around the world each year. Scientists estimate that spent coffee grounds can potentially add 340 million gallons of biodiesel to the world's fuel supply."

    and as the price of bio-diesel goes up, so does the cost of our coffee. Eventually, none of us will be able to wake up at all.

    ..It's sort of like future gas stations will make their own biodiesel or at least get it from a supplier within 25 miles in like 80% of populated US cities or something close to that...

    And in the unpopulated cities they have to rely on imports because the undead don't drink coffee.

    You tell me, is $60.00 bigger than $4.00? It's been a while since I took arithmetic but I seem to remember that this is so

    Confirmation on that, chief. $60 is more than $4.

    What would certainly get more expensive is instant coffee, because that doesn't produce waste coffee grounds.

    Instant bio-diesel? 2 scoops of powder, add water. Cream? Sugar?

    So, if you don't want the exhaust to smell like your breakroom after the dipshit from IT grabbed the pot off the hotplate while it was still dripping, do we want to add Irish Creme to the mix?

    Will they someday insist that we switch to decaf biodiesel to protect the environment? Do I have to stop telling the Barista to make mine leaded?
