...He is converting what looks like a home freezer and I've be interested to know if anyone has ideas for adapting this to a rv or marine size freezer....
Those in the world of off the grid living have had a few discussions on this writeup. Most with more knowledge than I can ever dream of having feel it's hogwash and they have good science explanations why. But none of them have tested this concept either.
