Hmm... wireless charging sounds pretty cool. But that is a lot more energy in the air than that of radio, Satellite, or cell phone signals, isn't it?
I am more interested in see the environmental and healthy study results of the impact of the wireless charging signal on human body. Cancers?
Reminescent of the Scaletrix race car game where toy cars were powered through copper brushes that sat in a metal track.
The plug-together race-track usually had two such tracks and shaped in a figure of 8 with single bridge to make the distance to travel the same for both cars.
Instead of wireless charging using the charging pads, if this technology can be extended to have conductive guide way on the road itself , using which one can directly drive the EV ( no need to charge) then that I could call a pulling factor to go for EVs. The on board batteries will be used only on the road patches where there is no such conductive guide way.
There is an argument that if it is less efficient in energy transmission that conducted charging it would be irresponsible to deploy it.
You would be trading convenience today for global warming tomorrow.
I am sure this technology will find some applications
Joshua Smith gave an excellent plenary on this topic at emerging technologies meeting in Vancouver last week, www.cmoset.com
But I am skeptical in applications of battery charging
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
