There is no need to worry about sending energy out unused. Because it resonates at a specific frequency, it is reabsorbed by the transmitter if it does not have a load to transfer to. Though I suspect that some of the energy will be lost in the ether.

It's sound good but I agree with what Angelboyfelyx yahoo said, the power efficiency seems too low and not practical. However, I believe technology will improve like adding smart antenna technology for transmitting, or add some initiate signaling to reduce power waste. Combining wireless communication technology and receiving initiate signal before turn on the device on the ceiling, use smart antenna or space diveristy technology to increase the power efficiency.

Yes, the power efficiency is 40% to 70% depending on the size of the transmitting coils and the distance between objects. Its not as efficient as say a power outlet, but it has its fundamental benefits of being wireless. Depending if the transmitting "antenna" (the coil) is designed poorly (intentional) it will radiate less power outwards. The better the "antenna" is designed, the more power it radiates. So in essence your trying to build a poor design antenna-wise (think wireless data) to negate power radiated. The power will only couple with other resonant objects in the room that have a receiver coil (much smaller) that will "couple" with the matching resonant frequency.

Queria saber si es que la coneccion en los locales produce algun tipo de efecno en la interface cerebral del hombre, pues como imagino que la mente trabaja con carga, nos cargariamos de corriente jajaja pero en realidad queria saber si hay efectos colaterales

It would be interesting to know what the efficiency of usage would be…are we 'wasting' electricity if we forget to turn the device off at night? Are we losing electricity if we don't have enough electrical devices on? Can we gauge the output with a rheostat like device? Our energy is still mass produced using nuclear and oil based methods…being inefficient would only add to current challenges!!! Sending energy out unused seems counterproductive as the economic and ecological cost of its manufacture increases. Angelboyfelyx yahoo
