  Wirelessly?

  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.

    The ones I have at home get it through the tracks.

      Which are just heavy gauge wires.
