Hi Roger,

I'm not sure if this is original to you, or one of those conceits that
is being passed around; but how, short of tagging energy (power?), can
you tell its origin? *In other words, delivery by return, or
completion of the path needs to be separable by some information about
the origin that to this point has been missing from the discussion.

If energy can be tagged with a return address, what is that tag?

I suggest that since the current at the middle of the line
is always 0, the power is always 0 and therefore no energy
crosses the middle. While tracking mixed energy is difficult,
when no energy crosses a boundary it seems easy to keep the
energy on each side of the boundary separate.

Hi Keith,

If you cannot identify the source, then you cannot proclaim a
separation.

That is hardly difficult. If no energy every crosses
the middle of the line, then the energy on the left half
of the line originated with the source on the left side
and ditto for the right.
