Usually, the type of people that drive around in alternative fuel vehicles emblazoned with decals bragging about what they are running on tend to lean a little bit towards the tin-foil hat wearing fringes of society.
Between all the broken links to overly ambitious side projects that never materialized and the hilariously bad doomsday-meets-#SEAPUNK imagery on his website, this guy meets some of the criteria. I’d say he keeps his radio on 550AM most nights, whenever he’s not working on his underground bunker or clipping coupons for canned goods to stash in his bug out spot.
I tend to stay away from these guys as much as possible. I also try to stay away from large quantities of highly compressed explosive gasses, and I suggest everyone else does as well.
