Here is some information that will start again the fears of those which think that Wi-Fi is dangerous to one's health. The company RCA announced that they are close to marketing a very special charger.
Equipped with an internal battery, this small device is able to charge or make function any object having a mini USB plug or more generally functioning with 5V.
The innovation is in the way in which the device recharges itself. It does not have power adaptor, nor a solar collector. "It quite simply" uses the Wi-Fi waves which pass through it and to recovers energy from them. RCA hopes to sell it for $40 this summer and looking further ahead wants to release a battery using same technology.
Of course, increasing the number of Wi-Fi networks will make these products will be effective. However it will be difficult to plan on transforming a Airport terminal into dock to recharge these products. The directional antennas being omni, only a small portion of the 100mW of the emitted power would be collected, while inevitably creating dead zones without reception behind these Airnergy devices since which all the signals would be absorbed.
PS: Fortunately that we are not closer to April first, since then nobody would have taken this advertisement seriously.
