this should be what every ones working on makeing methane gas for fuel it will help in two ways the fuel shortage thats on its way and will help the green house efect to manure helps make the green house gas plus it could be extracted right from the air to
Generating Methane Gas From Manure
25 years ago when I raised horses, I looked into manure/urine collection from the stalls to use in a methane digester. Methane is VERY explosive/flammable and back then a system was costly. Even the methane fuel cells today aren't cheap.
There was a story in the news today about a SF plan to collect food wastes from restaurants. They are brought to a bio-fuel plant where the stuff is left to sit and decompose, generating methane. The methane is then used to fuel a generator.
http://www.wisconsinpublicservice.com/farm/gasrecovery.asp i have a freind who makes his own from pig manure he sells of the extra pigs he all so has a trout farm in COL hes been doing it for 30 years or so he has a tractor he converted to methane and all his cars and trucks run off of it plus he has a whole hose Generator that runs from it to
This site contains a manual for the building of manure to methane gas units in Nepal.
Straus Family Creamery is using the methane from their dairy manure to generate power.
IMHO methane is another resource that should be being more widely studied and utilized.
These methane projects have been paying off - atmospheric levels have been stable for some time. CO2 is the big problem.
Thirty years or so ago, I was very interested in trying to establish a homestead based on organic gardening, re-cycling of waste materials, etc. I was an avid reader of Mother Earth News as was my roommate. At the time, the fact that burning methane produced just carbon dioxide and water sounded great when compared to all the chemical pollutants from gasoline and other common energy sources; however, now I'm concerned about the CO2 as it's a great contributor to global warming. Unless I'm totally wrong about this, it doesn't seem as though the production and use of methane would really do much to help get the planet out of the mess we've caused.
It does help - methane is a greenhouse gas. It's just not the biggest problem. And without getting into the controversial area, there is still MUCH we do not understand about the dynamics of climate. But cutting the use of fossil fuels is beneficial in so many ways.
If you build up the soil microbes, they will sequester a huge amount of carbon from the atmosphere. Conventional chemical ag kills off most of the microbes which then allows the carbon to be released into the atmosphere.
The thing about methane is its so abundant and would be released into the atmosphere anyway. There was study claiming that cow farts (methane) were tied to global warming.LOL I'm sorry but I am not willing to buy that we have to get rid of cows to stop global warming. As a matter of fact I'm not a believer in man creating global warming anyway. The earth goes through cycles, always has, man may be making a small contribution but I'm not buying that we are creating global warming and neither are many scientists. But I do believe that resources such as oil are not limitless and that man to be a better steward of the earth. Methane is a renewable resource and burns cleaner than fossil fuels, IMHO we should be utilizing more of this resource.
