Interesting News Story in my home town
I live in the "suburbs" of Raleigh, NC. I saw this on the news, apparently the guy that did this works at Wake Tech., one of our community colleges in the area. My brother goes there and I am gonna try to get up with the guy so that I can look at his setup a little closer.
Interestingly enogh it looks like he is using the water4gas design. I had no luck with particular setup. Who knows what he did different though
