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?
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
