The Japanese company believes a new computer modeling method makes wireless power transmission practical to build products by 2012. Here's a look at Fujitsu's technique.

Stephen Shankland worked at CNET from 1998 to 2024 and wrote about processors, digital photography, AI, quantum computing, computer science, materials science, supercomputers, drones, browsers, 3D printing, USB, and new computing technology in general. He has a soft spot in his heart for standards groups and I/O interfaces. His first big scoop was about radioactive cat poop.
A demonstration of Fujitsu's wireless-charging technique shows the ability to power one fan and two light bulbs at varying distances and positions compared to the charging station, the circular coil at left.
An example from Fujitsu's wireless charging computer model shows how magnetic resonance changes when the position of the the three small receiving coils are moved in relation to the one larger transmitting coil.
Fujitsu believes its technique, magnetic resonance, is better than an earlier method called electromagnetic induction, which requires precise and close positioning.
