Nokia have just blogged something pretty cool. They claim to be able to charge a Nokia Lumia 925 phone with lightning!
We were excited by this challenge presented to us by Nokia,” Neil explained. “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.”
What happened next surprised even the scientists, and Neil adds: “We were amazed to see that the Nokia circuitry somehow stabilized the noisy signal, allowing the battery to be charged.”
“This discovery proves that the device can be charged with a current that passes through the air, and is a huge step towards understanding a natural power like lightning and harnessing its energy,” says Neil Palmer of the University of Southampton who was brought on board for the project.
Not sure how practical this is but pretty cool stuff none the less.
