Well, that's definitely the right topic for the::unwired - even if not Windows Mobile related. Anyhow - as good and powerful mobile devices are today, sooner or later every mobile device needs a charge: from a simple MP3 player to a mobile phone to a Notebook and today, all these devices are charged using a power cord. Nevertheless, a team at the MIT (Massachusetts Institute of Technology) is working on the future in which wireless power transfer is feasible and charges devices without ever being plugged in, freeing us from that final, ubiquitous power wire. Some of these devices might not even need their bulky batteries to operate!

A team from MIT's Department of Physics, Department of Electrical Engineering and Computer Science, and Institute for Soldier Nanotechnologies (ISN) has experimentally demonstrated an important step toward accomplishing this vision of the future:

The team members are Andre Kurs, Aristeidis Karalis, Robert Moffatt, Prof. Peter Fisher, and Prof. John Joannopoulos (Francis Wright Davis Chair and director of ISN), led by Prof. Marin Soljacic.

Realizing their recent theoretical prediction, they were able to light a 60W light bulb from a power source seven feet (more than two meters) away; there was no physical connection between the source and the appliance. The MIT team refers to its concept as "WiTricity" (as in wireless electricity). The work will be reported in the June 7 issue of Science Express, the advance online publication of the journal Science.

Way to go - after cutting the line from the phone it's definitely the right time to cut the power wire from mobile devices as well!

Cheers ~ Arne
