It seems to be just around the corner. Several companies and institutions are working on this idea, such as the California Institute of Technology (Caltech), which has a project to capture solar energy in space and transmit it as electricity to earth, or Resonant Link, which is developing wireless chargers that would be placed on the streets to recharge electric vehicles.

But these are projects. U.S.-based Ossia (https://www.ossia.com/cota/), on the other hand, has already begun to offer licensing for its Cota wireless electricity technology, which allows electricity to be delivered wirelessly, through the air, over any distance. The technology, the company notes, has already been approved by the FCC in the US and complies with essential European and UK standards. One of its objectives is to power devices connected to the internet of things.

Another company that is offering a wireless device charging solution is Energous (https://energous.com/), which offers WattUp technology to charge devices wirelessly by touch or through the air.
