Last week I noticed an announcement of an eco-engineered car powered by used coffee beans (!) setting a Guinness World Record with a speed of 65.5 mph.
Apparently the “car-puccino” - actually a truck - works by heating coffee in a charcoal-fired burner, which produces carbon monoxide and hydrogen (ha, love chemistry!). Then the gases are cooled and filtered so that hydrogen can be used as actual fuel transferred to the engine. The whole process is called “gasification”.
I noticed there are a few handy people on Electric Forum attempting to make their own EV vehicles - kudos! But has anyone tried to build (or even heard off before! ) their own coffee or other domestic/industrial waste/byproduct car or bike?
