Thanks for the look.

  The foil is over heavy cord to act as an insulator.
Not that good but a bit better than nothing.

  I am using city tap water and I'm sure it is on the
soft side by intent.  I thought about adding a pinch
of salt, but engines do work so why push it.  Those carbon
blocks may be sensitive to salts and a bit too much may
doom them.
