With a lot of recent scientific data pointing to the adverse impact our reliance on fossil fuels is having on the environment, inventors, universities and entrepreneurs the world over have been tackling the issue of alternative energy in different manners. As we wrote about in 2008, the University of Reno had successfully developed a method for converting used coffee grounds into a form of biodiesel. At the time, the results weren’t mind-blowing — yes, it was feasible, but was it scalable?
Over a year later, the BBC1 show Bang Goes the Theory took the idea of turning coffee into a more explicit form of fuel by converting a 1988 Volkswagen Scirocco to use coffee as it test drives 210 miles from Manchester to London. Dubbed the ‘car-puccino,’ the project was taken on to accentuate the importance of experimenting with alternative energy. The catch, however, is the fact that the cost of the trip is between 25 – 50 times that what it would cost if petrol was used instead of coffee. Depending on coffee quality, the cost of the trip could be anywhere between about $1400 and $2800, compared to about $55 for a journey fueled by gas.
So, obviously, this may be a fun idea, but really not a great solution. Add to that the recent assessment by the International Coffee Organization that climate change has begun to severely impact the coffee growing regions around the world — which is contributing to the noticeable increase in the cost of coffee — and the idea of using java to power our favorite transport, digs and gadgets is even more ludicrous. But, we won’t slight them for trying — even if it was ultimately just a publicity stunt.
