    It also is less energy efficient as running the juice directly through a cable of course is more efficient than creating a magnetic field that then induces juice on the other side to flow again.

    It should be said that this is the principle of transformers, but they are built in an efficient way for it.

      Transformer without a core (which makes them about 90% efficient, while wireless at 70%, if perfectly aligned, rest is heat).
