Those from Nokia they have extremely interesting research and development laboratories, and you can see one of their important recent achievements in the video clip above. Basically, Nokia researchers they did it to charge one Nokia Lumia 925 using the energy of lightning simulated in the laboratory using 200.000 volts and an interesting set up. Practically, a Nokia Lumia terminal with an attached device is placed between two metal rods through which the electric current passes, the terminal charging without problems using the energy that passes over it.
For most of us, lightning can be a truly terrifying, powerful and awe-inspiring force of nature, but boffins (scientists for the rest of us) from Nokia and the University of Southampton put their heads together to try and tame the beast. They succeeded, and in a world's first, they were able to use simulated lightning to charge a Nokia phone. We were excited by this challenge presented to us by Nokia. Using an alternating current, driven by a transformer, over 200,000 volts was sent across a 300mm gap – giving heat and light similar to that of a lightning bolt. The signal was then stepped into a second controlling transformer, allowing us to charge the phone.
Although in the future we won't have to look for lightning to charge our smartphones, those from Nokia have demonstrated that wireless charging can be improved over time, users no longer having to place their terminals on charging devices. In practice, Nokia could develop charging stations that would allow the terminals to receive electricity at great distances from them, but for now everything is in the development process and it will certainly be several years before products of this kind reach the market.
