    Looks like a great way to "burn" coal.  Frigging energy companies are so cheap they don't even higher scientists beyond geologists running around looking for fossil fuels they can exploit.

Graphite carbon like the stuff you use for motor brushes it comes in various sizes and shapes even sheets. pencil lead works but it takes a lot of pencils.
  I think it was some guy named Bruce who has a water battery kit on the net. Sometimes you can score some left over inventory of carbon materials on ebay. It has to be solid if you just coat another material by coloring it with a pencil it doesnt do squat. Already tried that. I guess there needs to be tight bond for it to conduct well enough.

     If you look at the Periodic table carbon is in the same column as silicon-selenium-germanium-lead.  They are all semiconductors so they will all act as charge organizers.
