Electronics360: "Wireless power networks will soon transform power delivery: “This is not a science project”"

For low-energy usage, yes, wireless may be an option. We are looking specifically into the IoT space for this, so this article is helpful from that aspect. I wonder what the efficiencies, cost and volumetric space requirements (for transmitter & receivers) are, once you step up power to the kW-MW range, and increase distance parameters? Somehow I think the humble electrical cable has a little life in it yet.
