Coffee-Powered Car Breaks World Record
MrSeb writes "A bunch of tea-drinking northern Brits have set a new land speed record for a gasification-powered vehicle, fueled only by coffee beans. The car is called The Coffee Car, and it was created by the Teesdale Conservation Volunteers of Durham, England. The previous gasification-powered speed record — held by some Americans called 'Beaver Energy' — was a mere 47mph, fueled by wood pellets. The Coffee Car averaged no less than 66.5mph and was granted a Guinness World Record in return. Gasification is a process in which any organic fuel is turned into 'syngas,' a mixture of carbon dioxide/monoxide, hydrogen, and methane which can be used in conventional internal combustion engines. The Coffee Car was created with the sole intention of proving that renewable/green energy sources can power cars — and it looks like it succeeded!"
It also works with cellulose (the parts of the plant you don't eat). No strip mining, no tailings, no net CO2 (assuming you keep growing the plant, you are just cycling the CO2).
Why would one want to use dirty old coal?
