Wireless Electricity

Wow! Is it really possible?, I have heard of wireless mouse, wireless keyboard, wireless headphone, but electricity that seems impossible. how can you transfer electricity without wires? What about things and people coming in between the transfer. Won't they catch fire? Well, it may or may not catch fire, we don't know about that. However, recently MIT scientists have successfully demonstrated that electricity can be transferred through wireless. They successfully illuminated a 60W bulb located at approximately at 7 feet or 2 meter distance with a small interference (wall) in between power source and bulb. The MIT scientist dubbed this technique as WiTricity. WiTricity is based on coupled resonant object approach. Two resonant objects with same resonant frequency are able to exchange energy efficiently. Although there are various types of resonances like acoustic, magnetic, mechanical, electromagnetic etc., MIT scientist used magnetic resonant objects. The scientist informed that magnetic coupling is suitable for day to day application, as most common materials interact very weakly with magnetic field, and thus reducing the extraneous interference. Furthermore, magnetic resonance interacts weakly with biological organisms , hence, it is safe as well.
The scientist mentioned that it will primarily be useful for small household devices, which need to be recharged at regular interval. The initial candidates are laptop, house hold music devices, and small bulbs. It is very early to predict how useful and widespread WiTricity will be, but, it is not too far when wires will become obsolete. "Miracles do happen" isn't it ?

hmm.. seems interesting. I never thought it can be possible. I presume its initial application will be limited to office-space and household as the distance is just 2 meter.

hmmm...I strongly agree with cps :)

However,there is nothing to be surprised about any technological development because the sky is the limit....:)
