At CES, AA-Sized ‘Forever Batteries’ That Suck Power Out of the Air
The Consumer Electronics Show (CES), if you’ve never seen it, is a frantic tote bag of sore feet, glitzy product demos, hotel meetings and shopping malls. conferences and some major conferences and presentations. For every revolutionary product, there are twenty or so cheap imitations and bad ideas. But from time to time, a company presents itself with an idea that surprises you – and the battery Forever and its associated technology, nicknamed Cota, could someday be a product.
The Ossia battery company has developed a method of wireless energy transmission that they believe can recharge an AA battery (it is the picture below). above) or provide power to a smartphone that incorporates Cota technology natively or uses a specific charging case. Ossia has not revealed much about Cota’s operation, beyond a vague reference to it working as a Wi-Fi connection (not particularly useful). According to Ossia, Cota works because the Cota transmitter contains dozens of tiny RF antennas, with similar antennas mounted in the AA battery, a charging case or a hypothetical smartphone.
Using these antennas, the Cota transmitter can triangulate and lock on the Cota receiver. It then calculates the best signal path and transmits your wireless power accordingly. According to Ossia (who developed her own technology but fired her from other companies), Cota works by moving, in the corners, beyond the line of sight, and without regard to people or objects bothersome. Your giant collection of lead pipes from the sewers of the Roman Empire could still suit the poor. [Where exactly do you live again, Joel? -Ed]
The Cota-powered Forever Battery Ossia is intended for a device compatible with the Cota Transmitter, even if native support is not included. Theoretically, they could be used in TV remote controls, game controllers, AA-powered IoT devices, or any other product that requires normal AA batteries. In all honesty, it seems pretty cool. Whether it is successful is another question entirely.
There are already two other wireless power standards: Qi and Rezence. Ossia apparently represents yet another potential standard. And while the dream of an effortless wireless charging is a powerful one, we need to know more about such issues as the range of the transmitter, the power consumption and how the system absorbs more than Cota Forever battery power. It ‘s one thing to provide enough power to charge a cell phone from one foot, and something else to provide enough power to drive a game controller from within. a longer distance. The answers to these questions will answer how revolutionary Ossia and its Cota technology are.
