Q1. Where does this [source] energy come from?

An ideal source simply supplies a fixed voltage
devoid of any concern for efficiency or where
the energy comes from. This results in an
average steady-state number of joules being
supplied to the closed system per second.

Q2. Where does this [reverse] energy go?

Once introduced into a closed system, it obeys
the laws of physics including the conservation
of energy/momentum principles and the principle
of superposition of forward and reverse
electromagnetic fields. You can use an ideal
directional wattmeter to track the forward and
reverse energy flows through the ideal source.

Answer to both. We do not know and we do not care.

I have been telling you that your concepts violate
the conservation of energy principle and now you
have essentially admitted it.

But just as easily as it can supply energy, it can
remove it.

I'm afraid you will find that once the ideal source
has supplied the energy to a closed system, that energy
cannot be destroyed. If you are allowed to willy-nilly
suspend the conservation of energy principle, then any
magical event is possible and there is no valid reason
to even try to track the energy. It is one thing to
assume an introduction of steady-state power to a
closed system from an ideal source. It is another
thing entirely to allow destruction of that energy
once it has been introduced.
