4 Tons Of Plants per Mile to Ride In Your Car

Roland Piquepaille writes "As you might know, I enjoy big numbers. So it's just natural that I was attracted by this news release from the University of Utah, "Bad Mileage: 98 tons of plants per gallon." "A staggering 98 tons of prehistoric, buried plant material is required to produce each gallon of gasoline we burn in our cars, SUVs, trucks and other vehicles." For a reasonably efficient car, riding 25 miles per gallon, this translates to 4 tons of prehistoric plants per mile, or more than two tons per kilometer. The research paper also mentions that everyday, we are using the fossil fuel equivalent of all the plants growing during a whole year just for our cars. Even if these numbers are too large, this still makes you think about how inefficient our cars are. This analysis describes the calculations and contains other details about the research paper which will be published in November by Climate Change."

    Here! Here! And another thing...I'm not convinced that water is made of two hydrogen atoms bonded to one oxygen atom. I mean, how do "THEY" know? They can't really see anything that small. I'll bet its really bananas and pistachio flavored ice cream. And how do I know the sun really exists? I can't see the nuclear fusion occurring deep within its core even though I can feel the byproducts of it everyday. That's it there is no sun! .... (and so goes the raving lunatic, muttering to himself as he wanders the sidewalks in the early morning)

    No, ethanol is. Ethanol is more fuel-efficient

    Ethanol is more fuel efficient? How do you figure?

    Might want to check here. Check last paragraph page 2 "Some critics say that ethanol contains less energy per unit volume than unblended gasoline. This is true."

    Thank you, drive through.

    Creating biofuel artificially would be much more efficient (in terms of biomass used) than the natural process of fossilization.
