Researchers Make Gasoline From Cow Dung 201
McDrewbie writes "Yahoo! News has an article about Japanese researchers extracting a small amount of gasoline from 3.5oz of cow dung. The process uses application of high heat and pressure. Hopefully, when more information is released, we can find out how much energy it takes to produce this gasoline and how energy efficient the process is."

At least Japan knows how to PR the tech - you never hear about it here - which is just sad.

i actually thought the increase in oil prices would probably help this technology along. the only thing anyone has questioned about the process is the cost efficiency of making oil from thermal depolymerization versus the cost of just buying it from opec countries and/or successfully mining it from the oil shale in canada. i think the depolymerization method obviously has a lot more positives in its favor.
i also read that the livestock manufacturers, now understanding that their waste was actually useful and profitable for someone, had decided to charge for their waste product rather than just give it away, which was at least somewhat assumed by the cost analysis of depolymerization to begin with. even though it made sense at the time to assume that rather than paying for people to remove biological waste, they would rather have someone do it for free or even pay them for it, you can never overestimate the greed of corporations. i sure hope the technology continues to develop until it becomes more cost efficient. even if it can only reduce our needs for oil a small percentage, that would be a significant difference in our reliance on opec.

I've often heard that stated.
Unfortunately, since energy resources bestow both military and economic advantages to nation states, it is hard to see how consumption cn be reduced in a competitive global environment.

Oh the ass dump to gas pump tech is nothin. Did you RTFA?! There was far more disturbing technology at the end. Check this out, clart :
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 Co. spokeswoman. The extracted ingredient, vanillin, can be used as fragrance in shampoo and candles, she said.
Wow. Brings a whole new meaning to "tastes like shit."

After all, the market has clearly decided that the big oil companies, with their record-breaking profits [consumeraffairs.com], are the appropriate market solution to our energy problems. So why is the government interfering with the market and giving away $7 billion [freerepublic.com] to the oil companies?

Not that 1% of our fuel seems like a very big deal, but in order to replace petroleum as our primary fuel we are going to have to squeeze every bit of energy out of alternative sources and greatly increase efficiency if we want to maintain our standard of living. Thermal depolymerization may just be one of the pieces in the puzzle of keeping everything running. And the process can be run on many materials besdides just cow manure: first there are many other animals in the united states that create wastes (including people) that could be treated in a similar method, as well as offal from slaughterhouses, used fryer and industrial vegetable oil, possibly waste paper and construction lumber, grain silage... the list goes on and on. Combine the energy from that with some wind power, some solar power, some geothermal power, some hydropower, some biodiesel (where crops would be grown specifically for making into fuel, as opposed to using wastes from existing processes) and a good bit of nuclear power and we can hopefully put a serious dent into our petroleum usage. Efficiency increases through technology and plain old reduction in energy wasteful lifestyle choices will eventually have to fill in the gaps.
There is not going to be one magic bullet that fills our energy needs, we are going to have to develop and use many different sources to fuel future societies and waste reclaimation is one step in the whole issue. We will have to develop and test many different methods to find the right solution for the right application.
