Coffee as fuel for CAr??!!

The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules.

It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than conventional petrol and diesel can power vehicles.

The team calculates the Carpuccino will do three miles per kilo of ground coffee - the equivalent of about 56 espressos per mile.

The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey.

In total, the trip will use the equivalent of 11,760 espressos, and the team will have to take 'coffee breaks' roughly every 30 to 45 miles to pour in more granules.

They will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which is also generated by the process.

So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours.

Sadly, the inventors will still have to pay duty on their coffee fuel - even though tax collectors at Her Majesty's Revenue and Custom haven't yet worked out how much.

The coffee needs to be very dry and in pellets to allow the air to move through the pile of coffee as it burns. The brand doesn't matter.

This such a big suprise for me as scientist discovered that coffee can actually use as fuel just like petrol to make engines running.I personally do not hope this intervention would be working as this might make coffee more in high demand and maybe one day, we, the coffee addicts would not have enough coffee to drink.lolz.


  1. haha..u finally got a template with coffee!!! well done!! missing notts already =(
