No hands, no charging station. Alphabet is reportedly trying to give its self-driving cars the ability to charge their batteries without plugging in. Instead, they would merely park over street-embedded resonant magnetic induction transmitters and charge up wirelessly. Prototypes are currently being tested in two California locations. Eventually, with properly equipped roads, this technology could even see electric cars charge while they drive. Wireless charging would enable autonomous cars to carry lighter batteries and, if no longer tethered to charging stations, travel much greater distances.
