The track loop will probably get larger, rather than smaller. The technology they use to move the photons along is very similar to a rail gun, using magnetic polarization as the motive force. However, I can see making a much smaller version, modifying it slightly and using it as a power cell. Hmmm.... yeah. Sort of a Fission Drive.

Thanks, Chris! A whole new concept of portable power! Ronco's Fission drive! Forget batteries, which you have to throw away use costly rechargers! The Fission drive works on Quantum Technology and uses the power of the atom to create the power to keep all of your appliances running. When used with the Ronco wireless power distribution center, you can forget those clumsy wires and pull your electricity right out of the air, delivering it right where you need it the most!
