a current induction charger for a phone, that operates over about a millimeter of distance, is at best 70% as efficient as charging with a wire. The fact that this article omitted all details about efficiency, and omitted any numbers that we could use to calculate it, say it's probably not beating the standard induction charger's efficiency. I think this technology is more in the stage of "It's possible to do this!" rather than "it's practical to do this"
