Certianly not the only group to do someting like this but its a reall two-fer
T Boone Pickens wants to use natural gas to power cars.
Dary farmers ahd lots of stuff to get rid of and need to buy bedding.
So lets make methane (CH4) gas from cow poo! Besides there are regulations on how cow poo needs to be lagooned so it doesn't contaminate water etc.
If someone can make money at it so much the better http://www.farmpower.com/index.html
It seems like a way to abate the waste and make power or use the methane for other purposes (like even making ferterlizer).
One way to make it better .. using a methane reforming fuel cell instead of the methane powered generator - heat is still produced by the fuel cell.
Producing renewable energy from manure does not reduce food supply. While renewable fuels like ethanol and biodiesel currently divert carbohydrates and oils from the food chain, anaerobic digesters thrive on a wide range of organic wastes that have no food value
Unlike most other forms of agriculture, dairy farms can be self-sufficient in nutrients. The manure from one cow contains enough nitrogen, phosphorus, and potassium (the three numbers measured on fertilizer bags) to grow the crops that feed her. Most other crops depend on manufactured nutrients; the natural gas used to make fertilizer for just one acre of Midwestern corn could heat a house for a month.
Just like in Mad Max beyond thunderdome ... there is also a lot of Pig S#!T that could be used in the same process. So as long as there are feed lots that are used to farm meat there's going to be plenty available.
Do I think that this can supply all the energy needs ... Not a chance... can it be part of the solution definitly.
