Go, go (green) gadgets!

Bill McKee, of Xerox Canada talks about the erasable paper his company is developing.

How is it possible to create erasable paper?

The paper itself is just real paper, with a very thin coating of chemicals that contain light activated molecules. We pass it through a printer with an ultra-violet light bar that changes the color of the pixels … and thus erases the page.

How much can we save?

Estimates [say] more than 30 percent of printed office documents will be discarded right after being read.

What is the next step?

The team created a reusable paper that self-erased in about 16 to 24 hours. Customers wanted images to last for more than 24 hours. So, the team currently is working on a second version where images last 3 to 5 days.
