Here’s a scientific breakthrough that comes under the category: “What will they think of next?”

Researchers at Stanford University have come up with a way of making regular copier paper into batteries.

Basically, the scientists “painted” carbon nanotubes – tiny cylinders of carbon – on off-the-shelf paper and dipped them in a lithium-based solution. The nanotubes, it turns out, can store electric energy.

Why paper rather than metal or plastic? According to the researchers paper:

1. Is inexpensive and light in weight
2. Is well-understood
3. Has a built-in grid of fibers that’s perfect for storing electricity, and
4. Can be folded and rolled up without harming the battery.

As one of the researchers put it:

“The experienced technology developed in the paper industry over a century can be transferred to improve the process and performance of these paper-based devices.”

The technology is still in the laboratory stage, but don’t be surprised to some day see copier paper powering your copier.
