Re: How cool is this? Paper batteries
Actually this is better than a battery that has chemicals and wear out characteristics.
THey are referring to electrostatic storage devices called capacitors like the one probably in your PC now. These SUPER capacitors are to keep alive the memory of the cmos goodies.
Some of these were formed using carbon -charcoal like substrait which like activated carbon has very large surface area to volume. They can be charged and discharged rapidly and are even in model airplanes.
