The modern pace maker is totally shielded from any Electo/Magnetic waves floating about in the air. There is more to worry about this system than some one’s pace maker(I have one BTW). The cost and the drain on our present system of power generation would be prohibitive to say the least.
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.
You need to readjust your sarc detector.
