I'm in favor of "off the grid" living. (former liveaboard - the original "off the grid" folks.) I went back and watched the entire video. I learned nothing. I knew what this guy knows a long time ago and I know things he has yet to learn. Kudos to him for practicing his skills and reaping the benefit. If he believes the global warming crap he's a statist, or is at least, suspect. The video was beneficial for many, but I am not one of them.
