Cheap power generator could usher in a new generation of interactivity
A group of researchers working for Disney have created what might be the cheapest power generator ever made. The generator doesn't make huge amounts of power, but does generate enough electricity to light up LEDs and operate the screen of a digital reader. The coolest part is the generator makes electricity using nothing but paper.

The paper generator uses a paper material that has a semi-permanent electric charge. A sheet of Teflon is rubbed manually back and forth across that sheet of paper to create electricity.
The Disney researchers created a mechanical system that's able to harness the electricity created by rubbing those two sheets together to produce power. The researchers see the generator being the key to ushering in the new world of interactivity for magazines, books, posters, and many other things. One of the best things is that since the generator uses paper, it's very cheap.
