      Does anyone know specifically how the carbon polishing works ? Eg how the
      carbon selectively takes out everything else, but leaves the ethanol behind
      ? (or doesn't it !)

      It can't just be a pore size (sortof seiving arangement), because we expect
      it to take out both bigger (propanol, butanol, longer organics) molecules
      and smaller (methanol)

      Likewise, there's nothing special about the surface energies etc that would
      make it selectively bond to the others, is there ?

      What is the cause of the heat that is released when you add the carbon to
      spirit ? (is it a reaction, or a surface energy ?)

      Is this the same source of those wee bubbles that escape too - or is this
      just air being released from the pores ?
