"The container will probably have to be made of metal, how do you get electricity to the electrodes without touching the container or the liquid NaCl?"
Why does the container have to be made of metal? A ceramic container could withstand the heat better and be less conductive --mjgardes 22:43, 24 July 2009 (UTC)
A ceramic container would be more convenient but there are a couple reasons why I thought metal would work better. It seems like it would be easier to make a more resilient container from metal. With ceramic I would be too worried about it cracking and spilling the liquid NaCl. Ceramic is also more difficult to modify or repair (I think, I don't know as much about ceramics). It also seems like it would be easier to produce metal parts that are interchangeable and capable of creating an air tight seal. Metal is also more conductive of heat. This could be handy for keeping the pipes hot that transport the Na from the cell to the collection container.
