Anyway the current wireless charging is less efficient, and the “dispersed” power is transformed into heat, so yes, it’s always less environment friendly. The numbers of dispersed power are very small but on a very big scale.

I think that intensity could heat a metal object? Is all of the inefficiency of wireless power transfer systems due to thermal conversion/loss?
