That would be an interesting configuration to model in the manner that
Jim Lux suggested (using a set of resistive wires to simulate the tree),
but I'm pretty sure that the losses would be significant if the tree
itself was indeed lossy. Normally the fields inside a closed structure
are minimal, but that's because (unless I am mistaken ... which is
entirely possible) the E-fields generated by current through the various
wires/surfaces repel each other. If you put a lossy medium in the
middle they get absorbed before they repel each other.
I'm guessing that would be the second worst way to use a tree as far as
efficiency is concerned. The worst would probably be to bore a long
hole down the center of the trunk and run the wire through it.
Stealthy, yes ... efficient, no.
