anyway back to this joe cell thing, i went tru it again and you need a metal container, the anode ( as in the mark 1 ) which could be like a radiator overflow bottle, expensive but easilly accessable. the got holes that the gas stuff could come out, a cap that could be used to put the water in and could be used to position the cathode. 12v goes to the bottle and neg goes to cathode.

where do you get a cathode? a perferated one or somthin. and to get boost you add 1.5v battey or two for twins
