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!"

    Just for those who don't know. This was very popular during and after WW-II in Germany as gas supplies were next to non-existent. In these gasification systems, you could burn pretty much anything combustible. Wood was popular a popular choice. It's a very old technology.

    Not 100% related, but the original Diesel engine, ran on peanut oil. Fossil fuels only got used later in Diesel technology.

      It has also been used in South Africa. Also in both Germany and South Africa coal was actually the preferred feedstock and they would then take the process one step further creating liquid hydrocarbons like diesel, avgas, and gasoline. To complete the process to liquid you need the Fischer-Tropsch Process. You are correct in that this is old technology the Fischer-Tropshc process was first developed in Germany in the 1920 and creating charcoal has been around for a couple thousand years.

    They don't mention how they reach the temperature required for gasification of the beans. That requires some energy input, and they didn't say where that energy came from.

    Not that gasoline as we know and use it today comes with no cost, but if efficiency and cleanliness is what they are after, a little more disclosure would be useful.

    If it's sensible, this could be useful in some areas, for some vehicles. Looks like the whole gassification assembly is not exactly a work of precision engineering and could be built in somewhat sub-standard conditions. I'd expect that many third-world plantations of easily gassified produce have lots of leftovers and not all of those have sensible uses to date - some might be just dumped somewhere to rot.

    On a different note, if I were the CEO of Starbucks, I'd get such a car as a publicity and marketing stunt, and power it with dried left-overs from brewing.

    I have been around on some of the green energy vehicle forums (trying to figure out how to properly convert an engine to run on alcohol) and I have seen similar setups in the back of a pickups. There they had a wood fired gassification chamber that was filled with wood. I have built a similar setup that uses the syngas as fuel to make charcoal. Granted this is a very simple setup, one metal bucket with some legs on the bottom and a smaller bucket (needs to fit in the larger one) with a metal tube coming out and under to fire the larger one. Stoke a fire under it and about 30 - 45 minutes you have a self sustaining reaction. When the fire finally burns out you have a fair amount of natural charcoal. This is how I dispose of my brush and also keep in charcoal so I can barbeque every Friday, Saturday, and Sunday when the weather is good enough (less than a foot of snow on the ground and not 90+F with oppressive Minnesota humidity)

  13. Re:why coffee? by jm007 · · Score: 3, Informative

    If I had to guess as to why use coffee beans as fuel, I understand that when roasted, they are actually subjected to a process called torrefaction. In this way, moisture and other undesirable compounds in the raw biomass are boiled off. What remains has a Btu content just under that of coal, burns more consistently, and is resistant to moisture. Even if the coffee was first used to make the tasty beverage, I'm sure the used grounds would still have plenty of use as a gasification fuel.

    The costs of processing the 'fuel' is actually paid for by the first use of coffee: drinking. To get a ready-to-use gasification fuel as a by-product sounds like a great way to extend its uses.

    No what is really needed is to have the process be taken all the way to liquid fuels. This is a solved problem as the Germans did it in WWII using the Fischer-Tropsch process. With the same inputs we could probably get massively more useable energy from the resources we are currently diverting to corn ethanol, that and it wouldn't even be dependent on corn we could use input like switch grass, animal crap, animal processing waste, road kill, bamboo, yard waste, garbage, lumbar waste, or any other carbon based item we wish to dispose of.

    Um, I think there is, although you might be making some obscure point I don't understand because I don't spend all day on anti AGW sites:

    Climate during the Carboniferous Period

    from the fine article:

    Average global temperatures in the Early Carboniferous Period were hot- approximately 20 C (68 F). However, cooling during the Middle Carboniferous reduced average global temperatures to about 12 C (54 F). As shown on the chart below, this is comparable to the average global temperature on Earth today!

    Similarly, atmospheric concentrations of carbon dioxide (CO2) in the Early Carboniferous Period were approximately 1500 ppm (parts per million), but by the Middle Carboniferous had declined to about 350 ppm -- comparable to average CO2 concentrations today!

      Earth's atmosphere today contains about 380 ppm CO2 (0.038%). Compared to former geologic times, our present atmosphere, like the Late Carboniferous atmosphere, is CO2- impoverished! In the last 600 million years of Earth's history only the Carboniferous Period and our present age, the Quaternary Period, have witnessed CO2 levels less than 400 ppm.

    If you're talking about something else I'd sincerely be interested in reading about it.

    Gasification using a waste product would be more renewable and green. But coffee requires significant water, pesticides, and human intervention to grow. This is probably no better than corn ethanol fueling a vehicle.

    Except that they're using coffee grounds. To compare it to ethanol, you'd have to somehow be able to eat the corn first, and then make the ethanol from the husks/leaves that remain.
    All that aside, coffee grounds were just a whim, not a necessity. The rig they built should work just as well with any other plant-based left-overs (sawdust, leaves, lawn-clippings). Just compress them to have similar density and away you go...
