The folks at Xerox has been working on their "erasable paper" idea for some time now, but it looks like they've been making some real progress as of late, with them now even going so far as to say that they hope to have an actual product available sometime next year. The paper itself, however, appears to still use the same basic technology they've been working on all along -- namely, a coating of photosensitive chemicals that turn white when hit by ultraviolet light or react to product text when scanned specific wavelength of light. The text can then be erased on command by feeding it through a special printer, or left to disappear on its own over a period of 24 hours. On the downside, the paper is apparently useless if it's been folded or wrinkled, or written on with a pen. No word on an expected price for the paper or printer just yet, unfortunately, but Xerox seems to be betting that the savings in paper (and consequential environmental benefits) will be enough to offset whatever premium they'll likely cost.
