I have a question for everyone here. I was thinking the other day.... I got this septic system...alot of people got septics...its a digester that creates gas that comes out of the vent stack/pipe and vents to atmostphere?
Could anyone think of a reason that you could not use something (what im' not sure...super ballon maybe?) to harvest the gas from it?
What do you all think?

I don't know if it would produce enough to capture.
Only issue I could see would be a possible code violation, go throw a balloon up on your vent stack of the house and see what you get.
Would be interesting to see how much you can capture, would suck if the gas starts backing into the house. Be careful.

My dairy farmer neighbor is putting in a system that will capture the methane from his manure pit and dairy barn...I believe it is the start for some kind of new gov't regulation...the system is all pretty much being paid for by subsidies...can't wait to learn what they do with the methane recovered or the general efficiency in capturing it at all. I believe a lot of this was developed with Cornell University.

being that air needs to exit there also i would imagine it would be tricky to isolate the gas? This is not something I've thought of much..im ok with electric stove and woodstove for now lol.

What I have read about this process would have me questioning 1) if there is enough warmth in the tank to produce much gas (if any), 2) is the tank effectively SEALED to channel the gas towards collection and use? and 3) how are you prepared to store and use the gas? If you are set up for propane, that burns at a different rate/btu than methane (aka natural gas).
Its really a crying shame that all our 'wastes' are not channeled to being use-able in a cycle that functions instead of being polluting as a chemical sludge. And don't forget that septic tanks receive 'cleaning products' that will inhibit gas production AND foul up any resulting sludge that otherwise could have been excellent fertilizer for land uses.
A very good write up on this process and thoughts about 'alternatives' to standard septic tanks can be found in The Owner Built Homestead by Barbara & Ken Kern. (which KVR linked to a free online source for reading).
My personal motto - The Home, a peace worth fighting for.

As long as you don't flush the toilet or run a faucet there shouldn't be any air being pulled in, should just be the gas venting from your septic tank.
