 True, but the amount of such stuff you can feed through a given
domestic septic system is limited, - they are sized based on the
expected output from the building served. Even assuming a humongus
garbage disposal unit and a lot of spare time, the gas volume produced
would still be too small for anything but occaisional fill in use. - A
'gas turbine` forsooth???
 If he was willing to re-engineer and expand the whole system, and had
lots of additional biomass available the idea might have a chance but
the 'payback` time would be longer than most people would accept.
 Hog farms do quite well with methane digesters, but then they have a
surplus of 'riches` to work with, and their tanks are designed for the
purpose from the start.
