What I found interesting was where the article said "A Cota-enabled device sends out a beacon signal that finds paths to the charger, which in turn returns the power signal through only those open paths back to the receiver, avoiding people or anything that absorbs its energy." It sounds like

Chargers for small electronic devices that use low frequency induction at close range are common and harmless. But how about a device that is said to use many transmitters to focus energy at a rate of 1 Watt onto a device that is 30 ft away? Harmless?? http://tinyurl.com/oopg7l3 73, Erik
