The problem with magnetic flux coupling is keeping the surface of the secondary coil precicely perpendicular with the magnetic field lines. The less perpendicular, the less coupling and thus wasting energy. I am not sure this is a cost effective way of charging devices, this sounds like a step in the wrong direction. Besides that, where is the data from the study of how this will impact human health or is that not important?
Looking at the figures estimated and the aggressiveness of the mobile phone manufacturers it will be really giving a lot boost in the technical development of the wireless charging technology, yes there are many demands in terms of further development in this technique, but looking at the scope of the deployment it seems that this will open many new avenues in the field.
I wasn't trying to bash your article, just the technology. Just because something can be done, doesn't mean we should do it. The experiments that I have seen have a very low efficiency rating at around 50% at a close distance. One of them shows a 60W light bulb only a few feet away that requires 120W from the source. Now consider inverse squared law and that people might not want to use their devices close to the source, the efficiency will be somewhere much lower than 50% and probably near 5-10%. We are in the middle of a global energy crisis and this is the innovation that the public wants pushed?
There are many documented adverse health risks associated with electromagnetic radiation. It all depends on the frequency, the distance from the source, and the power level. Let's use a microwave oven for example, they operate at 2450 MHz but are strictly regulated to 5mW of microwave radiation per cm^2 @ approximately 4 cm from the oven surface. The inverse squared law takes care of the rest, but it is that same law which diminishes the efficiency of wireless power and thus making people decide if they want to be close to a radiation source to improve the efficiency.
Regardless of the frequency, this radiation causes "electric dipole moments" in every atom and molecule in our bodies causing them to change alignment at a rate consistent with the chosen frequency. I am not sure that changing every household, diner, and coffee shop into an energy wasting microwave oven is the best course of action for the world.
Unfortunately, "TPFJ" is probably right. Too much money has been invested and is at stake for the proponents to hang up their hats and back out now.
OK, time for some self-humiliation: I saw the title to this one and immediately thought "What!?! Phone companies are already making out like bandits, and now they're going to charge us 40 times more??"
