Radio waves are also electricity didn’t you notice? Waves that travel on air to your phones or AM/FM radios by capturing it to an antenna. So, by creating a smaller “radio” transmitter for your home, you can also wireless charge your devices.

A UK firm has also discovered this and developed this idea using multi-band antennas to capture different “radio stations,” to increase the electricity harvested, for low-energy IoT (Internet of Things).

This is exciting times since by this you can wonder how this technology could change our lives by using “free” electricity. Just as Nikola Tesla (the inventor) has envisioned. It’s like that movie where Doctor Octavius wants to harness the energy of the man-made sun to provide cheap electricity for the whole world. Not a lofty goal but perhaps a crazy one (haha).
