According to the ScienceDaily article, “The scientists estimate that the process could make a profit of more than $8 million a year in the U.S. alone."
The Nevada researchers hope to now develope a small plant to produce their coffee-ground biofuel. Tests they they perform over the next few months will garner more information on the viability of using it as fuel.
This could eventually mean that Starbucks coffee drive-thrus, and other such coffee drive-thrus, could be used to buy coffee to drink and, at the same time, to fill up the bio-coffee--grounds-diesel fuel tank of your car.
We have been getting scientific reports of some of the benefits of coffee. Now, it looks like coffee may be a viable way to power our way out of our energy problems.
So, drink up for a greener tomorrow.
