All About Biogas

Understanding what it is and how to build a digester
Friday, June 21, 2013, 2:50 PM

Lots of new info flowing on the Internet these days about biogas and methane digesters.  Here is a recent post form John Robb at Resilient Communities about using biogas for increasing one's resiliency.


And here is a DIY tutorial I came across on how to build your own small-scale digester.

A summer project I have lined up is to build a digester and then try to connect it to a small propane-powered refrigerator.  It would be a wonderful addition for grid-down situations.

Let us know


I have looked into building a "Biogas digester" for a while. I would love to read and see what you have done later this summer. I believe this is also called an anaerobic digestor. I wish that I still had the links to the videos that I had found. There were some videos by a man out of Germany that made one to power a small refrigerator.
