Me, too. However, consumers might not care (unfortunately). In other
words, you might pay 15% more to cover losses but compared to what?
Consumers will be happy to just park and have the charge happen
automatically. Unless energy costs are really high, they will get
ignored.
I'm with you, though. When a simple direct connect is nearly 100%
lossless, and so easy to plug in, why would I want to be so wasteful?

Inductive EVSE for i3 EV
My problem with the whole wireless charging "dog and pony show" is the
lost energy and the seemingly impossible efficiency claims.
For instance, even if the high frequency transformer had NO air gap,
there would still be a limit to its efficiency.
How efficient is a 60hz transformer? Is a higher frequency transformer
any more efficient?
