Combine a bit of coffee fuel with some WVO and the aroma should be like breakfast - hash browns and coffee - mmmmm...

Would be nice.

A buck a gallon.

Now were talking!

I'd much rather smell coffee then fries. It would be good to get this going... drive through coffee shops and re-fuel.

From the Journal of Agriculture and Food Chemistry, how they did the process of biodiesel from coffee grounds. If I could understand the extraction process, I'd be trying this right now:
"Oil Extraction Spent coffee grounds were dried overnight in an oven (Isotemp 655G) at 50 °C to remove moisture (mostly 50−60 wt %) and then refluxed for 1 h with low-boiling organic solvents such as n-hexane, ether, and dichloromethane to extract the oil from the coffee particles. Three hundred mL of solvent was used for 100 g of dried spent coffee grounds (adjusted to 95% dry matter basic) for the extraction of oil. All of the experiments were carried out using a 1 L round-bottomed glass flask. The resultant solution containing 15 g of oil was separated from the spent coffee grounds by filtration using a Buckner funnel under vacuum. The oil was separated from the solvents using a rotary evaporator. The solvents were reused in the next batch of extraction. The collected crude oil was characterized and quantified using HPLC. The free fatty acids (FFAs) present in the crude oil were separated by converting them into soap by mixing a basic solution with the extracted oil. Soap was removed from the pure oil by centrifuging the mixture for 30 min (5000 rpm; Beckman centrifuge model J2-21).
Transesterification Process In a typical transesterification process, first the coffee oil was heated to 100 °C to remove the traces of water present, and the oil was mixed with 40 v % methanol and 1.5 wt % catalyst (KOH). The reaction mixture was refluxed at ∼70 °C for the biodiesel production. Optimization of the reaction was carried out by varying the amounts of methanol, KOH, and reaction time (through HPLC analysis) to get maximum yield. The reaction time for a complete transesterification process was monitored through HPLC using methanol, hexane, and isopropanol as solvents (see the Supporting Information for details) (18). The reaction was stopped when the oil (mostly triglycerides, TG) peaks in the HPLC analysis disappeared, and the peaks corresponding to biodiesel were saturated. The reaction mixture, after the reaction, was cooled to room temperature and allowed to stand overnight. The bottom layer of glycerin was separated from the biodiesel layer (top layer). The produced crude biodiesel was then washed twice with warm water (40−50 °C) and acidified water (0.5 wt % tannic acid) to remove the excess methanol and the traces of catalyst (19, 20)." = Coffee Powered Delica
If you can figure out how they are getting the oils out of the grounds, by what ever method that will not kill you, let us all know.

get a couple bags from a Starbucks (they stack them by the register once in a while for free). then try some stuff, A press and/or a centrifuge comes to mind as those can be used to get oil out of algae.
