If you do it exactly as described, there will
be a lot of 'missing' (i.e. dissipated) energy
that is accounted for by the gigantic spaaaakk
that occurs when you make the connection.

Since we are "gedankening" let me observe that there
should be no spaaaakking in a "perfect vacuuuuum,"
i.e. in space without atoms. Yes, I am superficially
aware that the term vacuum became ambiguous.
