On December 31, 2014, Elon Musk tweeted: “We are actually working on a charger that automatically moves out from the wall & connects like a solid metal snake. For realz. This can be used with all existing Model S cars, not just future ones.”

Musk first mentioned the automatic charging idea in October 2014 at Tesla’s Dual Motor and Autopilot unveiling when he teased some driverless functionality as “exciting long term possibilities.” He said that Model S could soon park itself, and also come to you when summoned, even using your online calendar to determine where and when you need it.

This morning on Twitter and Facebook, the company released a video of a hands-free automatic charger prototype.
