Nokia has been pushing the cell phone technology every single time they introduce something for the world, and this time they came out with the idea of wireless charging. No wires at all.
Nokia is working on a technology which harvests ambient radio waves from the air, and turns that energy into usable power.
Nokia originates the idea from the radio, TV and cell phones transmission waves which exist all around us and use them to charge the nokia phone. Nokia phone picks up these waves and uses the electromagnetic energy to generate electrical current for the battery to charge.
