I remember when they won a province wide business plan contest in Vancouver, BC, and it was noted that a key reason they won (the 100k prize) was that they had an engineering review indicating their process was feasible.

I think I might just have to try it out at home sometime.

Anyone know what would make a good salt bridge that's semi permeable to na/cl (or how to treat the polystyrene)? Would an U shaped jello mixed with acid/base work?
