Researchers at the Korea Advanced Institute of Science and Technology (KAIST) developed an incredible wireless charging system capable of charging around 40 smartphones simultaneously from a distance of 5 meters.
The contraption, called the Dipole Coil Resonant System, uses magnetic fields to transfer energy rather than physical charging cables. It is based on the Coupled Magnetic Resonance System introduced by MIT researchers in 2007. The Korean-developed system is an improvement on the MIT system however, in that it delivers more power at shorter distances. It is able to transmit 471 Watts of power from a distance of 4 meters, and 1403 Watts from a shorter distance of 3 meters.
While the wireless charging system has demonstrated its compatibility with smartphones, it can deliver enough juice to power larger devices like TVs and computers.
