A couple of comments on your post(a) 18 and 19.
First I have no idea if this scheme is viable... That said, there is a big difference between magnetic coupling which is what is being proposed, and electromagnetic waves. The former does not propagate energy, the later does.
What they are proposing is basically a transformer with the primary being in the pavement and the secondary being on the buss. Transformers can be designed to be very efficient. Well over 95%. This design would be very problematic, but I wouldn’t go so far as to say it couldn’t be done.
As far as the energy costs go, it wouldn’t be any more than conventional electrical propulsion, and it would probably be a bit less.
I stand by my statement that this will be cost prohibitive if large numbers of vehicles are charged this way.
