- Wireless charging technology has a fascinating history and an incredibly exciting future. It’s so much more than charging plates and cellphones. In our previous post about wireless charging, we alluded to some of the advancements it took to bring us to this point in technological development. But today, we’ll dive further into these chapters of history, discovering where wireless charging technology came from, as well as what the next year, decade, and century could hold for this innovation!
Our Favorite Inventors!
The idea that energy, power, or electricity could be transferred between points has been around since at least 1831. At the time, it was Michael Faraday leading the charge in this area, demonstrating that magnetic induction can occur when you have an oscillating electrical current in one coil of wire sitting close to another. This wasn’t a particular practical solution, however, as Faraday’s system needed enormous magnets to function.
But then came Nikola Tesla, probably one of humanity’s greatest minds. That idolization by technology nerds is probably why there are now a multitude of electric cars on the road that bear his name. Tesla was born on July 10th, 1856 in the then Austro-Hungarian Empire. By 1884, Tesla had moved to New York to fulfill a dream of harnessing the power of Niagara Falls for electricity generation, while working alongside Thomas Edison. Soon, however, the two would begin to butt heads, with Tesla recommending the widespread adoption of an allernating current (AC) electrical standard over Edison’s direct current format.
Wireless Charging Technology – Today and Tomorrow
The present and future of wireless charging is incredibly exciting. And it’s so much more than electric toothbrushes. Yes, the fact that IKEA, Starbucks and plenty of other household names are jumping into the wireless charging arena with integrated furniture and the like is fun, but it’s the real innovation beyond these feats that’s exciting.
Take uBeam for example , which is harnessing the power of ultrasound (yes, the same thing doctors use to get glimpses of unborn babies) for wireless charging that’s safe and ready to move larger distances. Also in this race is Stanford University, which has recently achieved a very near recreation of Tesla’s dream of true wireless, over-the-air, energy transmission. Those working on the team believe that if scalable, the technology could be used to wirelessly charge electric cars on the roads as they move about, completely eliminating the need for fossil fuels.Disney has even created an entire “wireless charging room” that will provide a constant supply of power for up to 10 devices at a time!
