the advent of wireless electricity
Qi, according to ancient Chinese philosophy of medicine, is the energy that flows throughout, in and around us. Qi is what is responsible for all things alive.
Now, building around this philosophy, the Wireless Power Consortium has done some remarkable research into inductive charging behaviour. Unlike traditional conductive charging, that makes use of wires, this new technology is able to generate electricity without the use of wires. As a result, devices can be charged wirelessly.
Here’s how it works, basically: There two coils, a transmitter coil and a receiver coil. An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil.
This new technology is at the present, targeted towards low-powered devices, such as mobile phones, that require less than or equal to 5 Watts. But further research into inductive charging is able to produce as close as 120 Watts. Wireless Powerless Consortium has in its alliance, leading consumer brands of the world, including Nokia, Energizer, Sony, Huawei, Samsung and Sanyo among others.
Honestly, it is about time to forget the cords and wires; and seriously contemplate Qi.
