The article is only talking about wireless charging, not magnetic mooring and does specifically mention that the system will work "Efficiently" with up to 50 cm air gap between the ships coil and the shore side one, so in this case I think conventional mooring lines will be used to secure the ship to the quay. To me a 50 cm air gap would appear to be very inefficient when you think about the lengths that Motor and Alternator makers go to to minimise air gaps and all that stuff in magnetism about the inverse square law. However, they don't put any figures to it, and I have heard some people are trying to put electro magnets in the roads to charge electric vehicles as they drive over them, the cost of that would be horrendous and the efficiency minimal, I would suspect.

It is always better to ask a stupid question than to do a stupid thing.
