Small scale biogas digesters built with local material by local people.

I'd like to include discussions regarding biogas generation in this group, if no one objects.

Brian from Inspiration Farms and I have discussed and plan on building a small scale biogas digester this spring and start planning for a larger unit that can handle the waste generated from his farm and collect the gas for cooking, lighting, heating and possibly powering a generator is sufficient volume is produced (possibly only during summer months). Ideal use of this biogas is to have it fuel a fuel cell and produce electricity much more efficiently and quietly than a generator.

Here is the pdf of the manual that we are going to use to help us with our full scale digester.

Here is a good video Brian found:

Anyone want to volunteer and help with this project?

Here is some interesting info on a small unit for sale in india for converting food waste into biogas. Brian (Inspiration farms) and Tom Anderson build one along these lines. I want to build one too for my household compost waste.
