Charging a Lumia 925 with lightning bolt

Published by at

A partnership between the University of Southampton and Nokia has resulted in an experiment that saw a Nokia Lumia 925 being recharged by what is effectively a lightning bolt. It's not something that you're going to be able to try at home, and we don't expect to see a lightning enabled portable battery charger accessory anytime soon, but it does demonstrate the ability of the charging circuitry to deal with even very noisy signals (good news if you're electrical supply isn't stable).

The experiment demonstrates that a device can be charged by a current that passes through the air. The scientist behind the project, Neil Palmer, notes that this "is a huge step towards understanding a natural power like lightning and harnessing its energy". Plus, of course, there's something rather funky about charging your phone via a 200,000+ volts discharge, even if it does fail the energy star rating tests spectacularly. 

Here's how the experiement was set up, as explained by Palmer:

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.

We were amazed to see that the Nokia circuitry somehow stabilized the noisy signal, allowing the battery to [start] be charged in only seconds.

Nokia have partnered with the University of Southampton to unveil ground-breaking, proof-of-concept research into harnessing the power of lightning for personal use, an industry first that could potentially see consumers tap one of nature's significant energy sources to charge their devices in a sustainable manner.

This experiment underlines Nokia's 150-year commitment to innovation and delivering the most pioneering products to its customers. That the Nokia Lumia 925 could withstand this sort of experiment is testament to the renowned high quality and durability of Nokia's devices and the company's continuing research to increase the already outstanding reliability of its products.

These experiments are conducted by professionals in laboratory conditions, please do not try this at home.
