Detroit is now home to the country’s first chunk of road that can wirelessly charge an electric vehicle (EV), whether it’s parked or moving.

Why it matters: Wireless charging on an electrified roadway could remove one of the biggest hassles of owning an EV: the need to stop and plug in regularly.

      Not wireless. Overhead contact lines are wires they just skim along them.

      Comparison for this would be a metal brush dragging the ground over electrical contacts to maintain connection. Which would be a third rail on roads, very dangerous.

        Guess what’s inside your wireless charging port!

        The point is, there’s no physical connection being made.

          … Yes there is in trains. Not in wireless charging. I was correcting your comparison.

            Electric trains gather energy by running a conductive element along suspended wires. No connection made.

            Wireless chargers charge devices through induction, in which a coil of wire produces a magnetic field, inducing a current in the wire coil in your device. Both have wires, neither make connections, we call both wireless.
