Experimental Xerox paper erases itself
Feel guilty about those documents you print out, only to be read once and then tossed? Not guilty enough to strain your eyes reading every last word from your computer screen? Xerox Corporation thinks the answer may lie in “erasable paper”—a printing technology still in early R & D, which relies on specific wavelengths of light to print images that fade completely in 16-24 hours leaving blank paper for reuse. If the technology proves commercially viable it should drastically offset the amount of paper going to waste. According to Xerox, two out of every five pages are read only once before being trashed or recycled.
