A Printer That Removes Ink

Scientists have created a printer which can, using lasers, remove ink off of previously printed paper - to be reused. Green laser passes through the paper's cellulose while vaporizing the ink.

Aside from never having to buy paper again, "unprinting" is a more "green" method than recycling which also uses more electricity, CO2 output, and fresh water.
