Conservation of energy means that energy is neither created nor
destroyed, but that heat and other forms of energy are quantitifiable
and convertable in their equivalence. The total amount of mechanical,
thermal, chemical, electrical, and other forms of energy in any isolated
system remains constant. A century ago, Einstein broadened the law to
include equivalence of mass and energy.

Regardless of reflections and re-reflections, all the energy sourced
into a transmission line ends up in the load if it isn`t lost in
transmission by radiation or conversion into heat. There`s no place else
for it to go.

Yes, thanks Richard. It is quite a simple concept. But my contention
really isn't about conservation of energy. It's about the 2nd law of
thermodynamics. Nature does not require a rolling ball to run through a
Rube Goldberg contraption in order to conserve energy. In fact it
generally abhors such things. "One should not increase, beyond what is
necessary, the number of entities required to explain anything."
