Wireless Power

Can it be true? Completely cordless electrically powered devices? We already have wireless data transmission in the shape of the radio since the early 1900’s and recently we have had the wireless phone or mobile phones. But on Thursday,Intel the world’s largest semiconductor company demonstrated a truly revolutionary technology by sending power to a 60 watt light bulb without the use of a wire. You can read more about this here. I wonder how will I calculate power then? Do I measure the electrical resistance of the air?

After a little searching of the internet, I found out that the research into this technology has been going on for quite a long time. A large scale version of this technology had been tested by NASA in 1975 transferring 35,000 watts of energy over a distance of 1.5 kilometres.

The following is a product video by a company called Alticor showing what can be possible with such a technology. It would seem that this company has already employed their own version of cordless power since the year 2000 in the form of its water filtering system.
