Airnergy Charger charges Wi-Fi gadgets. Issue price of $ 40, waiting for this summer
At CES 2010, a power supply device was demonstrated, but it extracts energy ... from the environment.
More precisely, uses the energy of radio waves. More precisely - the radio waves used to transmit the signal of wireless networks Wi-Fi .
So welcome, RCA Airnergy Charger
Knowing how popular wireless networks are, it is easy to imagine that the electromagnetic field generated by Wi-Fi transmitters has rather high tensions, especially in central quarters with a high office density. However, a simple calculation shows that this field is enough to cause a headache in easily inspired individuals, but not enough to charge the batteries of modern mobile devices for any reasonable time. In order to intercept a noticeable amount of energy, one should position the Airnergy Charger directly next to the antenna. Anyway, the received energy is stored in the built-in battery, from which you can charge a cell phone or PDA battery.
')
The expected price for an unusual charger is $ 40. The appearance of the Airnergy Charger on the market is expected this summer.
On the Internet, they believe that either a clever mystification of the source takes place with the purpose of laughing at unsuspecting readers, or Airnergy Charger will be recharged from the network, and the ability to “charge” from Wi-Fi will be used only as a marketing bait, but will not have practical value in force of negligible efficiency.
