Phun things to do with a pressure cooker.
. . . an agriculture engineering professor at the Tokyo University of Agriculture and Technology, said his team has successfully extracted .042 ounces of gasoline from every 3.5 ounces of cow dung by applying high pressure and heat. . .
The team, helped by staff from the National Institute of Advanced Industrial Science and Technology near Tokyo, produced gasoline 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 (572 Fahrenheit), Shibusawa said. Details of the catalysts could not be disclosed, he added.
hmmm, I wonder if this has a net yield of energy when all inputs including the energy embodied in the equipment and catalysts is considered? If not there may be better uses for this discovered resource.
In a separate experiment revealing another unusual business potential for cow dung, another group of researchers has successfully extracted an aromatic ingredient of vanilla from cattle dung, said Miki Tsuruta, a Sekisui Chemical 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.
Dung shampoo? We'll need some serious marketing brainstorming to find a way to turn the suspicious origins of the product into an asset.
