Researchers develop 'WiFi for power' that charges from 15 feet away

If Chun Rim, professor of Nuclear & Quantum Engineering at Korea Advanced Institute of Science and Technology (KAIST) has anything to say about it. Rim and his team have developed an inductive wireless charging system than can beam power up to five meters away. Like the inductive charging systems in Qi and PMA, the KAIST wireless power system relies on transmitter and receiver coils, but those standards have nowhere near the range or power demonstrate here. The team managed to get this astounding range out of its coils by developing a new mechanism called the Dipole Coil Resonant System (DCRS). This technology was designed specifically to solve the problems with MIT's Coupled Magnetic Resonance System (CMRS) for wireless charging at a distance. CMRS was able to beam power up to 2.1 meters away when it was developed in 2007, but it was woefully complicated and inefficient.
