Cheaper Veggie Diesel May Change the Way We Drive

Japanese scientists may have found a cheaper and more efficient way to produce "biodiesel." The renewable, vegetable oil-based fuel can be used in conventional diesel engines, which are found in about 2 percent of cars currently sold in the U.S. and in about 40 percent in Europe.
The breakthrough could be just in time—industry experts say that demand for the cleaner, greener fuel is on the rise.
Any vegetable oil can become fuel, but not until its fatty acids are converted to chemical compounds known as esters. Currently the acids used to convert the fatty acids are prohibitively expensive.
Michikazu Hara, of the Tokyo Institute of Technology in Yokohama, Japan, and his colleagues have used common, inexpensive sugars to form a recyclable solid acid that does the job on the cheap. Their research is reported in last week's issue of the journal Nature.
"We estimate the cost of the catalyst to be one-tenth to one-fiftieth that of conventional catalysts," Hara said.
The breakthrough could provide cost savings on a massive scale, he said, because the technique could fairly easily make the transition from the lab to the refinery—if interest warrants.

Every time I've looked at
Every time I've looked at the arithmetic of such ventures, they're shown totally impractical as an actual replacement for automotive fuels. What they usually turn out to be are requests to fund research into the economic equivalent of a perpetual motion machine.
For example, it's shown that adding 10% alcohol to fuel as a way to reduce petroleum consumption, ends up raising petroleum consumption, because it takes more petroleum to produce the alcohol than was saved by the consumer. Alcohol producers conceal this fact, and convince the government to forcefully transfer money to them.
Biodiesel is of course interesting, but, you know, where would you grow all those oil producing plants? If the whole of South America were planted in soybeans, would that meet half of current diesel demand? And can you be profitable at $6/gallon or so? At that price, the alternative petroleum sources, oil saturated shale and sand, are seriously competitive.
