Here is a story about Cow Power in Vermont (story from Oct 2007). The methane is collected from the cows manure (at that time it was around 700 cows that they collected the manure from), and stored until processing. At the time of the article, there were over 4,400 people that were buying electricity that was made from Cow Manure.

And here is a link to the California Poo Project....they are doing the same thing on their dairy farms.

Seems like a smart idea!

It is funny but I purchased stock recently in a company that makes fuel from sewage including human and animal waste but it is not methane. They call it MagneGas and it is a natural gas (methane) substitute. This is a rather high tech solution but it just uses an electric arc under water and without oxygen to atomize waste and it sterilizes it at the same time. The residual material is a sterile fertilizer mostly and this MagneGas fuel.

The stock has tripled in the last few weeks. I am very happy with the idea that I am making money from poo. Poo into gold so to speak. It produces more fuel than just a methane breakdown of the waste and is faster and more compact.

They are going to make a home unit that can fuel your car over night using your waste. You got to love that idea. It does use electric power but it makes a lot of fuel for the money. It produces fuel at the cost equivalent of $1.20 per gallon gasoline. It also has more oxygen left after combustion than methane and less NOX and CO2. It is nearly a perfect fuel and the fact that it is made from waste is just a win win in my opinion.

Sorry to resurrect this old thread but I did not pay attention and missed your question. The process for MagneGas takes minutes to produce a quality liquid fertilizer and an efficient gaseous fuel from human or animal waste.

The home units I keep bugging them on but the company president wants to sell cutting gas and sell plants in Europe and Asia. They are not that interested in the home units. Perhaps if I organized a share holder meeting and put that on the agenda it would get bumped up in their priorities a bit.

I hear what you are saying. All of the pathogens can be controlled in a methodical application of composting discipline.

The problem I have is the "methodical" and "discipline" parts. I worked on ranches where we raised horses, and composted the excrement. But if you have a lot of practice with composting animal crap, you know that there is a great degree of variability in each pile. Weather conditions, stomach contents, etc, mean that each pile needs to be worked differently. And when you make a mistake with grazers, the problem is simply having some poo that needs to be composted all over again.

But with omnivores, it is far more complicated, and the poo is much more variable. I have experience with pigs. Pig poo is the most difficult livestock poo to deal with, because it has such a high concentration of nitrogen (horse hit is a distant second). Nitrogen will kill the composting organisms, and worse (as has been learnt in industrial pig operations) can leach into to the groundwater. My understanding is that human poop, even under the best conditions, is almost as bad as pig, and takes 2 YEARS of composting to fully transform. That means that it will be twice as expensive as fertilizer, as any livestock poop.

You can probably do it on a personal scale, with an individual who is a true believer. But the idea of even getting a whole village to compost their crap safely and completely, is not believeable to me.

Have you ever used a latrine with a group of other people for a week or more? I got back recently from a hunting trip with 5 others, and we had to move the latrine every third day. And we had a nice seat and everything. But your composting will be as weak as the weakest member of your team. Hep C may not seem like a real threat, but what about dysentery?
