I wonder if Tesla would consider (or if it is possible) using Energous wireless charging technology in a near future.
A brief description of the technology from Energous web site:
"Energous Corporation is the developer of WattUp®—an award-winning, wire-free charging technology that will transform the way consumers and industries charge and power electronic devices at home, in the office, in the car and beyond. WattUp is a revolutionary radio frequency (RF) based charging solution that delivers intelligent, scalable power via radio bands, similar to a Wi-Fi router. WattUp differs from older wireless charging systems in that it delivers power at a distance, to multiple devices – thus resulting in a wire-free experience that saves users from having to remember to plug in their devices."
