Has anyone ever built and used a biogas generator for generating home electricity? There are plans for building one are available online for a backyard setup called the Liberty Generator (I bought some for about $37 and watched the video and looked at the plans, not sure if I have been ripped off yet) from a survivalist website that is definitely a little "scammy" looking, and haven't tried to build it (not sure my husband will let me...he's skeptical of anything that nobody else in the neighborhood does, which would include many typical Mustachian practices such as riding bikes everywhere and using a push reel lawnmower) but I wanted to see if anyone has tried this. My research about it sounds like the idea of building a biogas digester really does generate methane and is used in third world countries for cooking (like propane or natural gas for stoves, etc), and in some cases runs the electricity at a farm using manure and organic waste. The people who sell the plans claim you can reduce your electric bill by up to 90% by feeding the biogas digester your yard clippings, weeds, food scraps, etc (they say that some people add their pet waste or connect sewage lines). It looks like it should work, but I am not sure I would always be around to "feed" it waste and keep it going, which I think needs to be done every few days. It sounds like an interesting idea, and we live in an area with frequent gray skies and our house is shaded almost all the time with trees so solar won't work here.
Here is the website (
