The Use Of Radiowaves
Right now, many think of radiowaves as the stuff we use to listen to the radio. While this is true in part, radio itself has changed a lot over the years. As a result, radiowaves themselves are no longer used like they use to be. This opens them up to be accessed by technology. Radio waves themselves are a form of electromagnetic radiation that we are able to access and send signals through. That is likely because they have the longest wavelength in the electromagnetic spectrum. In 2050, buildings will access them and be able to charge your devices without needing to plug them in. Start-ups like Energous, among others, are already working on stuff like this right now. Just imagine how this will look by 2050.
