TOKYO - Scientists in energy-poor Japan said Friday they have found a new source of gasoline — cattle dung.

Sakae Shibusawa, 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.


This is is great cause as it states in the article this will help in the disposal of large amounts of waste produced by the cattle industry and we get gas out of it too.

I don't know the numbers, but I think it would[/I] be cost-effective if the operation is decentralized. The scientists are improving efficiency to make it commercial. Perhaps they can make the generator small enough to produce the fuel needs of a small farming community. I've seen a German invention that converts the farm wastes into small dry pellets that can be either disposed of easily or fed back into the machine to be burned and produce electricity. Pretty cool stuff.


I have no idea how many cows there are in America. The rough rule of thumb I calculated is “A half million cows equals 30 thousand barrels of fuel.” I was using 42 gal to the bbl. Any help is to be appreciated. Yes, I can imagine how in states like Wyoming or the Dakota’s, small communities could be fueled by cow dung. Maybe the school kids could collect it during the summer vacation? I’m skeptical of all this vegetables to fuel hype. Like grow our way out of addiction.

The cost to prepare land for planting, the cost of planting and plowing, the cost of harvesting, storing, transporting, and so one, including the cost of fertilizer and etc., makes renewable energy more a political ploy than a real life plan. The only thing we can hope for is to greatly improve gas mileage - like to make 50 mpg the MINIMUM allowed, and to convert to electric cars for places like Manhattan, re-charged by coal fired steam generating plants. We can, we must, clean up the discharge from those plants.
