Xerox’s Reusable Paper

Almost half of the paper used in American offices is for daily use. It is for display, not storage and, at the end of the day, it’s in the trash can. All of the energy that was put into harvesting, processing, and shipping that paper was, in the end, for less than a day’s use. A number of companies are working on alternatives to this procedure.

The system is based on ‘paper’ that contains light sensitive materials. When exposed to certain wavelengths of light, the paper changes to a darker that then slowly fades. Neither the light-sensitive paper, nor the light printers are ready for consumers

Interesting. It is great to see all the efforts undertaken by scientists and engineers to improve. The more we can have working everywhere in the world the better off we will be.

    I really like the idea, but it would seem more useful to me if the ‘ink’ was more “permanent” and that it took a different wavelength of light to “erase” with. As with most stuff like this though, the cost of the paper and the printing technology will initially be prohibitive.
