Scientists working on wireless power

Posted on Thursday, November 16 2006 @ 10:51:05 CET by

Scientists are developing a way to transfer power wirelessly. This could be useful for consumer electronics like MP3 players or laptops. Here's a basic explanation of how it works:
1) Power from mains to antenna, which is made of copper
2) Antenna resonates at a frequency of 6.4Mhz, emitting electromagnetic waves
3) 'Tails' of energy from antenna 'tunnel' up to 5m (16.4ft)
4) Electricity picked up by laptop's antenna, which must also be resonating at 6.4Mhz. Energy used to re-charge device
5) Energy not transferred to laptop re-absorbed by source antenna. People/other objects not affected as not resonating at 6.4Mhz
