No, it has to be less efficient...wireless radiates in many directions (even if you use resonance like in this case), you have to be a right place with teh reight surrounding for an optimum energy transfer...it is more effcient with wrires for sure, the only question is by how much...Kris
Thank you Mark for pointing this out, here is the link for others to enjoy:
I need to point out the obvious though: the energy used for charging wirelessly those EV cars will have to come from somewhere! so saying "moving beyond oil, fossil and radioactive fuels" is a bit premature to say at least...Kris
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.
