One additional note to all this.. i think the biggest roadblock to wireless charging isn't safety, its that it could very well be rendered obselete by next generation energy storage.
research into Lithium sulfer/solid state type batteries and other next generation contenders are making serious progress because theyre being driven (CWIDT?) by the electric car market.
If wireless charging takes 3 years to get here, it might well be released into a market where charging your cell phone means plugging it in for an hour or two once a week.
You make a really good point. I did a post about the next generation energy storage technology and seems like that is further into the future than wireless charging.
Lets see how all this plays out.
