It seems this is 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, and Resonant Link, which is developing wireless chargers that would be installed on streets to recharge electric vehicles.

But those are just projects. The U.S.-based company Ossia (https://www.ossia.com/cota/), on the other hand, has already begun offering licenses for its Cota wireless power technology, which delivers electricity wirelessly, through the air, over any distance. The company notes that the technology has already been approved by the FCC in the U.S. and complies with essential European and U.K. standards. One of its goals is to power devices connected to the Internet of Things.

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