Looks like a great science experiment and engineering challenge but I can't see the practicality of it. 90% efficient is spectacular for inductive charging but far below what can be achieved with plug in. With the costs of electricity involved here 8-9% efficency is large. If you've got to have your car parked for two hours or more then the effort of plugging it in is very minor.
Is the vision that we would install inductive coils in our garages?
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.
