>> Back in the 40's the Goverment in India commissioned a chap by the
>> name of Ram Bux Singh to develop and promulgate small scale methane
>> gas digesters for the rural countryside of India. Reason? India has
>> been de-forested by its huge population and there are few natural
>> resources to supply for common needs such as fuel for cooking.
>>
>> The impetus for this work was the fact that while Indians for the
>> most part do not eat meat, yet they have a lot of sacred cows walking
>> around leaving cow chips everywhere. So for lack of anything else,
>> people would gather these cow chips and burn them for fuel. There
>> were so many instances of people going blind from the fumes rising
>> from burning manure, the push was on to use this "natural resource,"
>> bovine manure and convert it into a form of fuel which does not pose
>> a health risk.
>>
>> Back in the 60's when John Schuttleworth was still the owner as well
>> as the founder of the Mother Earth News, John brought Ram Bux Singh
>> to the US and to his folk's farm in Indiana to direct the building of
>> a methane gas digester on the Shuttleworth farm. All of this was
>> documented in a book published by Mother Earth News.
>>
>> As an aside, pioneers crossing the grasslands of the US 150 years ago
>> in covered wagons on their trek west were sometimes at a loss for
>> fuel on the open prairies. But there were buffalo chips to gather for
>> cooking fuel. Some of those folks developed visual problems much like
>> the people in India and didn't make the connection to burning raw
>> manure as the cause.
>>
>> Ram Bux Singh proved that small scale methane generators work. I
>> picked up on this work back in the '60's while teaching high school
>> in Montana. Many of us were attempting to discourage the strip mining
>> of coal which cuts into the acqifer and destroys the ground water
>> table.
>>
>> Converting animals manure much as human manure has been done in
>> sewage plants for over 100 years into useable fuel and enhanced
>> fertilizer seemed a natural. And so it has been.
>>
>> I am much opposed to animal confinement operations for a variety of
>> reasons. However, even animals that free range often deposit a
>> considerable amount of manure in one place. Chickens, for instance,
>> drop much of their manure under their roosts at night.
>>
>> To maintain that a digester has to be big in order to work is much
>> like saying that the only airplanes that will fly are big ones like
>> the Boeing 747. Piper Cubs and Cessnas simply will not work.
