Bruce Davis on thu 22 dec 05


Back when I was engineering I saw an article about a rural Chinese methane
generator that was a combination of a septic tank and a composter. They had
a septic tank half buried in the ground that was used for human waste. It
also had a chute that they used to dispose of organic refuse from farming and
household garbage as well as animal waste. All of the methane gas which was
spontaneously generated in the tank went through a water trap into an
accumulator where is was a piped to gas lanterns and a cooking stove. It was a
fairly simple energy source and I suppose it could be harnessed for use by
potters as well if you could get a sufficient volume of gas.

I Bruce, all...


I just realized, reading your post here, that all these years, on top of my
building, is a four-inch Cast Iron vent pipe, which constantly is sighing
methane.

Now, If I had ( or would now even ) make some simple contrivance to collect
it...

I could do something with it...

Anyone on city water, city sewers rather, has similar vent pipes, some of
which might just be good perennial gassers of constant methane.

Since I have been on the roof lately working up there, I became aware of
this Pipe...otherwise, I knew of it only in the side of my thoughts, and
never noticed it's constant odor of Sewer Gas wafting out of it.

Phil, every house with a septic system has those gas vent pipes to let the
methane gas out, not just those with city water or sewers. Also if you
have drains that don't have water in the u part it will let the gasses out
into your house. So actually we all could have our own energy supply.
Who ever came up with the way to do so safely would be a very rich man!

Some friends of ours had a wood log home built and when the logs settled
it crimped the vent pipe so when the toilet down stairs was flushed the
gasses needed somewhere to go and burped in the upstairs toilet... wasn't
much fun if you were sitting on the upstairs toilet when it burped!

Pinky in MN, it feels like spring today, close to 40 degrees.

Keep in mind that trapping bio-gas from any source, must be oxygen free in
order to be put to any useful purpose!

Phil- Methane gas has no odor. It is the bio-materials from which it is
generated , that give it odor. Natural gas, also, has no odor, but the
slight input of dead rats, is infused in the line, which makes it
identifiable.

If you cap off your vent pipe with an airtight flexible catch bag; i.e.
truck inner tube, etc., place a valve, and an air compressor, on the catch
bag, you are now accessing a free fuel source. Don't light a sparkler to
celebrate or you might be going into orbit!

Bruce- Didn't "Katrina" create an ample supply of organic materials in Gulf
Port? What an opportunity for a person with your background and
understanding of bio-gas!
