Xerox prides itself on being on the front line of development in the paper industry. Using a new light technology, they have found a way to reuse paper, by having it self erase after 24 hrs. Ingenious.
“The “a-ha” moment came from developing compounds that change color when they absorb a certain wavelength of light but then will gradually disappear. In its present version, the paper self-erases in about 16-24 hours and can be used multiple times.”
Somehow that makes a lot of sense, but doesn’t at the same time. Weird.
