I saw this featured in Time as one of their inventions of the year. I've seen “digital paper” before, but this is a concept where you can print and then easily erase the paper for re-use. This would reduce waste, right?
It was interesting to see comments on this “TreeHugger” site that implied the re-usable paper is a bit of a workaround, it's not really getting to the root cause issue — why do you need to print?
Still this is an interesting application for those times you have to print a document for single time use.
