Wireless Power what is it about

I have been hearing the term wireless power more and more the last couple of days. and it was piquing my interist. Then I saw a post on about it on one of my news letters that I subscribe to. Wireless Power I was thinging it had to do with wireless networking but if you read this post for which I will provide a link to the post http://blogs.techrepublic.com.com/tech-news/?p=640&tag=nl.e102 is more about transfering power wirelessly say to a light bulb. This topic will be interisting as it develops in the IT world.
