You’ve probably heard this before but I had this exact idea back while studying at university – seriously.  Wireless charging could revolutionize the way we think about and interact with our electronic devices, whether it’s a smartphone, tablet, portable video gaming system, etc.  Induction charging gave us a glimpse of this a couple of years ago but it never caught on big because it still required contact between the charger and the device, plus a hefty add-on for the device.  The Cota, made by Oassia, sends power from the source to your devices using the airwaves, the same 2.4 GHz spectrum that WiFi networks and Bluetooth communication use.  Like these two wireless standards, Cota does not require a line of sight and is capable of charging multiple devices at once.  Imagine your smartphone automatically being charged whenever you’re at home, without having to plug it in?  Cota is said to have a range of up to 30 feet.  Currently only about 10 percent of the power source arrives at the device that’s being charged, so the efficiency isn’t very good at all.  But as with any other new technology, we expect this to be boosted significantly in the future.  Cota is currently being reviewed by the FCC for approval and the company hopes to license the tech to consumer electronics manufacturers by 2015.  We can’t wait for this tech to arrive!
