A laser unprinter!
Yes, that does say a laser unprinter. Recently Cambridge researchers have successfully utlized a way to recycle paper already printed on without damaging the underlying paper. This can not only save trees, but can also significantly reduce climate-change emissions from paper producing facilities and recycling centers. The laser printer is still in prototype; however, once someone is willing to sponser the project, we may just be re-using the same piece of paper for years to come!
This article sparked my interest because I am a huge advocate in recycling to help save the planet. Plus, now when I screw up on my homework I don't have to use a million sheets of paper before I get it right. (And I'm talking about that pamphlet)
