I've been losing motivation lately, but if people are really into it I guess I could buck up a bit. Maybe.
Research note: LPG is stored in spherical containers too: Wiki on LPG. LPG contains high proportions of either propane or butane or both and is highly flammable (duhhh). Theoretically enough of it could make a pretty fine mess of a pretty large area, which is why it is always stored with extreme care.
