Re: There's work, and then there's work

Having read this never-ending thread can I offer one comment.

Even IF it is valid to talk about the energy of the positive charges, it is
NOT energy that is 'stored' in any meaningful use of the word.  There is no
way to recover that energy.  The calorimetry experiments that Ludwik
suggests DOES measure the energy that is usefully stored in the capacitor
and that can be recovered.
