Cattle futures on the rise?

I'll admit at the outset I'm intrigued by this article. I hope this proves to be workable but I'm afraid they'll use so much energy in the conversion/extraction process it won't be terrible useful.

On the other hand, I'm a little distressed by the last few paragraphs. I really can't imagine that cow dung extract in shampoo is going to be a hot selling point.

imho [:D][:D]

Scientists extract liquid motor fuel from cattle dung

TOKYO (AP) - Scientists in energy-poor Japan said Friday they have found a new source of motor fuel - cattle dung.

Sakae Shibusawa, an agriculture engineering professor at the Tokyo University of Agriculture and Technology, said his team has extracted 1.4 millilitres of a gasoline-like liquid fuel from every 100 grams of cow dung by applying high pressure and heat.

"The new technology will be a boon for livestock breeders" to reduce the burden of disposing of large amounts of waste, Shibusawa said.

About 500,000 tonnes of cattle dung are produced each year in Japan, he said.

Liquid fuel from cow dung is unheard of, said Tomiaki Tamura, an official of the Natural Resources and Energy Agency. Japan relies almost totally on imports for its oil and gasoline needs.

The team, helped by staff from the National Institute of Advanced Industrial Science and Technology near Tokyo, produced fuel by adding several unspecified metal catalysts to the dung inside a container and applying a 30-atmosphere pressure and heat of up to 300 degrees Celsius, Shibusawa said. Details of the catalysts could not be disclosed, he added.

The team hopes to improve the technology so that it can be used commercially within five years, Shibusawa said.

In a separate experiment revealing another unusual business potential for cow dung, another group of researchers has extracted an aromatic ingredient of vanilla from cattle dung, said Miki Tsuruta, a Sekisui Chemical Co. spokeswoman.

The extracted ingredient, vanillin, can be used as fragrance in shampoo and candles, she said.

Tsuruta said the vanillin was extracted from a dung solution in a pressurized cooker in a project co-organized by a Japanese medical research institute.

Your second sentence unfortunately says it all.There are versions of this process being developed all around the world but they are all energy hungry of course.

The problem is why are they all so slow to come to market? Biodiesel should be widespread by now, at least B85.

Now if only they could make fuel from horse manure...I'd be all set.

If we had stationary coils and moving magnets incorporated into our keyboards just think of the wattage that would generate.
