Turns out you may make biofuel from just about any sebaceous plant Cartesian product . Zea mays may be the standard , but coffee works at least as well , and it get to your car smell like a Starbucks !
Experts say it takes about 5 - 7 kilo of coffee grounds to get one liter of biofuel , which with a intermediate - sized production would generate a cost of about $ 1 per gallon . Plus , it ’s already used : you may just walk around to your local coffeeshops and convenience computer storage and stock up the same way you would on vegetable oil .
create fuel from the grounds use the same operation as other biodiesels , transesterification , which is sort of complicated to explain but fairly inexpensive . The US estimates we consume over 7 tons of coffee each twelvemonth , which would yield about 340 million gallons of biodiesel .
But mostly , a elusive coffee scent might get over the significantly less savory olfactory sensation presently dominating my car . [ The Economist ]
