Wireless power?

One of my biggest material design dreams would be to have wireless power. That you wouldn't need a plug when using your laptop, yeah I know such a thing has a battery. But as your laptop gets older the battery gets useless after a while. Further it would be great just to take your laptop with you without any cables. Theoratically seen this would mean that you also can charge your mobile phone or iPod anywhere.
Well back to reality, there is a company that claims to have a wireless power technology called eCoupled, based on an induction technology. More info on their website.
