Sheesh Marshall if you don't know anything more about basic physics you really shouldn't be commenting on this
FCC approval only means one thing really, it won't interfere with other RF devices and nothing more ..... That means it's going to be low power and thus won't be able to charde anything with any kind of reasonable efficiency ..... In fact this will make the incandescent light bulb look like the model of efficiency and they've been all but banned
The ON:Y thing this device will do is create excess CO2 from all the WASTED electricity and all because people are too damned LAZY to plug a cord into their device to charge it ...... If the losses from this are over 2 then it should be banned and most likely the losses will be on the order of 10 or greater (Likely much greater)
I agree with longjohn, you know the inverse square law and all that stuff.
Having said that the only benefit that this system would have is that it would eliminate the wear and tear on the micro USB connectors used on phone & tablets. I have lost one phone and had to have a tablet repaired because the micro USB connectors used for charging failed.
Micro USB connectors were never designed for constant plugging an unplugging that occurs when phones/tablets are charged on a daily basis.
Interesting article - but this is not a new concept!
Nikoli Tesla would be saying "I told YOU SO". He actually was the first to conceive and research this technology to transmit energy through the air by wireless transmissions.
Another interesting article is: https/www.smithsonianmag.com/history/the-rise-and-fall-of-nikola-tesla-and-his-tower-11074324/
A quote of this article says: “As soon as completed, it will be possible for a business man in New York to dictate instructions, and have them instantly appear in type at his office in London or elsewhere,” Tesla said at the time. “He will be able to call up, from his desk, and talk to any telephone subscriber on the globe, without any change whatever in the existing equipment. An inexpensive instrument, not bigger than a watch, will enable its bearer to hear anywhere, on sea or land, music or song, the speech of a political leader, the address of an eminent man of science, or the sermon of an eloquent clergyman, delivered in some other place, however distant. In the same manner any picture, character, drawing or print can be transferred from one to another place. Millions of such instruments can be operated from but one plant of this kind.”
If Tesla had not been cheated out of his finances and inventions and went broke and ocd we probably would have had much of our current technology much sooner. Imagine what our technology would look like today if Tesla had been able to finish what he had started. He's been dead around 74 years now but many of his dreams and ideals are now a reality .
