actually they are starting to do so..engadget(i believe) had a video link from youtube about a university lab were they wer able to light a bulb about a meter away..the equipment is huge though so it aint practical yet..

The amount of power that can be transmitted and the distance it can be delivered is directly proportional to the size of the coil and the magnetic conductivity of the material being used for the coils. Even with advanced materials, we're reaching really, really close to fundamental laws of the universe that determine how well this technology is capable of performing.

It's the same reason you have to use electron microscopes and other imaging methods to look at samples of really, really small particles and viruses. You can't use a traditional lens microscope, regardless of theoretically perfect lens-crafting, because the particles themselves start to become smaller then the wavelength of visible light and the beams you're trying to observe simply pass over the particles without causing any refraction. These fundamentals cannot be overcome directly, we would need to discover a whole new non-magnetic way of wireless power transfer to create the type of power transfer environment that would make any sense over long distances.
