    when you have to connect it to something, it's not wireless. quit wasting my time. Wifi is termed "wireless" - even though your 802.11-enabled router is plugged into the wall, and is probably externally connected via an ethernet cable. Your reply might be "Yes, but I can receive a signal on my laptop without the laptop requiring a cable". Well, the same applies here. Your phone can charge without needing a cable plugged into it.

    (Or MPT) is an actual working technology already in use - I seem to recall a small experimental, remotely controlled, airplane that was powered this way. A ground microwave dish followed it as it moved across the sky and that powered the motors and other scientific experiments. On the other hand, a stationary object such as a cell phone shouldn't have a problem being powered in a dedicated recharge zone (such as a counter or shelf that would be designated as a human-unsafe area). Wikipedia claims that power transmission efficiencies and radiation are mostly negligible -- if so, does that mean that we should be going after it or is there inherent danger to the process?
