Yesterday, Xiaomi and Motorola showed us the future, presenting their new wireless charging technologies. You're accurately read about it and heard, so we will not retell the news in the word. And let's talk about the fact that in the same hour, as companies showed their novelties, all over the world began very hot discussions on how dangerous these concentrated rays of charging "by air" for people began. In general, where is our cancer of the whole organism, and who will cultivate it now?!
Xiaomi has their new Mi Air Charge, judging by the press release, does not notice any obstacles between the power source and the charging device. Power is enough to punish anything and charge smartphone. Hence the first questions about what will happen, if the obstacle becomes a person.
Announced your charging, Motorola decided to show that if the device is overlapped with hand, the charging stops and resumes immediately after removing this hand. It became somehow a little calmer. But questions still remained. For example, why do such a charge need, if you can easily be covered with your hand. It means that it can be stopped by any other things.
In Motorola, all this understood and hurried to make several refinements of yesterday's announcement. And on this occasion, one video was published, where it is demonstrated that the charging does not stop if all sorts of items should be discarded between the power supply and smartphones. Because the device can identify the human body and only then the charging process is interrupted. The head of the Lenovo mobile office has explained that this is a security feature that works exactly so as not to harm user health.
It follows that all the same technology can affect the body, since the security function was invented? So far, there are no answers to this question, but we are already wanting to complete the delivery of such charging, just in case lead panties and armor were lying. But this is still all of us, as ordinary people, will not explain why it is safe and how can you live with it. Still, a millimeter range (30-300 GHz), in which the smartphone with an efficiency of 10% can be charged on a removal of several meters using a small modest antenna of this smartphone - something is somehow not very safe looks. And even quite the opposite.
