DON"T TRY THIS. The home septic system has an open end at the inlet, the vent and the drainfield. An attempt to presurize the system to fill a gas bag would displace the water out of the plumbing trap into the home and blow the gas back into the house.

lol. just a thought. i think you may be right. oh my. i guess the correct set of check valves and venting could help, but i will admit it is a bad idea.

There sure seem to be a lot of people in places like India who are generating methane and using it successfully. How hard can it be???

I like the fuel cell idea of converting it to electricty and storing it...

Anyone know of any research on that end?

Yep,sort of,its what the Shatz hydrogen project thread I posted is about,only their premise is solar panels>split hydrogen/O2>store hydrogen.During day they use solar,at night run hydrogen through a fuel cell for electric.
I think thats a pretty nice setup for sure,but the costs must be skyhigh.

Pretty much the same idea.Lots of conversion loss in battery storage though.Dont know anyone is doing it,doesnt seem to be much biogas online in US.

What if all those homesized biogas methane producers were hooked to the grid, then there is no storage, just a decrease in your own electric bill/fuel use. Sounds like something our co-op would be interested in, if it was viable I mean.

I recently seen a picture of something along those lines. Somewhere in in China I believe. Seems these folks tapped a natural gas pipeline and took to filling up very large plastic bags full of the gas and bringing them home for cooking etc. As bad as most plastic is with static electricity I can see that being quite hazardous. I doubt I'm the only person here who has filled up a surplus weather balloon with propane and applied a spark. OK, maybe I am, but the effect is memorable to say the least and it is probably one of the most entertaining uses for surplus weather balloons besides hoaxing UFOs.

When I first saw the header of this post, I thought "methane generation" was referring to the next generation, like Generation X or the Baby Boomers. I think my 9 year old son is definitely a member of the methane generation.
