Right. Thanks. I had completely forgotten that. However, we still have a
radiator of some substantial size to design in. Actually, now I think on it,
we have a natural. Just transfer the heat to the cable. Since we are
climbing it, we would only leave a little heat at any given point, so we
wouldn't heat it much.
