Do not rely upon the production of human methane to heat your entire house, water,
power, etc. It should be only a back-up system. You must install a valve and gauge to
monitor the pressure in the sewage collection tank. If at any time it gets too high you'll
have to burn it off, so make a big dinner that evening or jump start that wood stove on a
cool autumn night. Use standard gas lines as you might for natural gas throughout the
home, use smaller lines to connect to fixtures and appliances, etc. (The one thing for
which I only have an estimate is the amount of gas the average piece of poop will
generate. Based on the number of times and duration of each "gaseous exchange" I have
emitted on those days of intense activity - usually after baked beans or a varied diet the
day before - I estimate about 3 cu. ft. per 4 oz. piece in about an hour.
