WIRELESS AA BATTERIES THAT NEVER RUNS OUT OF JUICE




Almost a century ago, the Internet's favourite super-genius, Nicola Tesla, was obsessed with wireless power transmission. He believed power was essentially a right, and he wanted to deliver it to the world free of charge. Ossia has taken it as a challenge, working to fulfil the inventors' promise of readily available electricity wherever you go.

The company, Ossia, is effectively trying to create a new system for in-home, wireless charging. This is not like the Qi chargers or whatever else you have used in the past. Ossia's systems will let you charge your devices anywhere within range of their base station.

This could lead to AA batteries that never need to be recharged, or iPhone's that are pretty much always road-trip ready. The actual mechanism behind the tech is pretty complicated, but it is also easy enough to shrink down that the company has made standard battery-sized versions. Phones require a special case for now, but could one day see the tech as a default inclusion, although that is likely some way off.

For now, the company is looking to drive early adoption with their specialised "Forever Battery." With this tech, you would not need to worry about your Xbox controllers or TV remotes running out of juice. Even better, the batteries themselves are able to be, at least, partially controlled through cloud systems accessed via an app.

The whole system uses a remarkably complicated, yet elegant solution. Obviously, it would not do just vomit power through the air – which is basically what Tesla tried to do way back when. Not only is it inefficient, depending upon how that is implemented, it is not even necessarily safe.

Instead, equipped devices will fire off a signal to the base station about 100 times every second. The base station uses an array of tiny antennas to calculate the exact location of the device it needs to route power to. The device is smart enough to account for walls and objects in the room. Once it is picked up the exact spot of your device, it can shoot powerful RF signals back in reverse, which is picked up by the device's receiver and translated into power that you can then use. Ossia's latest version can transmit power a short distance around any number of obstacles.

In time, the company hopes its all-in-one chip can be shrunk down enough to slot into already crammed smartphones but, for now, we can at least have smart batteries that will never die.
