I have been told by two different people that Mother Earth News had a methane generator design on one of their archives from the 70's - I have tried a couple of times to find it unsuccessfully - maybe one of you will have better results. I am very interested in a small scale methane generator.
Also - have you guys built one of these magnetic generators? When it sounds too good to be true....
I'm just finishing my hydro unit for powering my house - more on another posting.
