Wireless charging

In the last few years things appear to have moved on with wireless charging now available at very competitive prices. I assume the device has to have a way of receiving the inductive field. Is that what they mean by "QI compatible"?

I expect some amateur radio manufacturer will catch on so that some 2m and 70cm handhelds can be charged by simply placing the rig on a charging pad. I would expect this to be a flexible PCB coil within the battery. They could even reduce bill of material (BOM) costs by building the cells within the radio body and not even selling a charger. I expect either a Chinese manufacturer or ICOM will be first. You can imagine the Yaesu engineers saying "that's a good idea, why didn't we think of that?".

Wireless charging from roads - NOT amateur radio

To me, this has to be the answer to a carbonless future with regard to road vehicles. Southgate News reports on trials in France and Israel where the road has embedded wireless charging for road vehicles. This means smaller, lighter, batteries in the vehicles, a longer battery life, and greater range.
