That's what this Airenergy from RCA claims to do, one more device in the long list of wireless energy promisses that we're still waiting to see delivered. According to them, it can "charge a mobile phone battery in little more than 90 minutes."
Well... if that sounds too good to be true, so did to several other people who took the time and effort to do some calculations where they concluded that such device would take over 30 years to charge a cell phone battery using a single WiFi signal (and assuming some very "lucky" conditions.)
Let's wait to see how RCA responds to that...
