Wahey, another day another theoretical display that will revolutionize the world, this time one that fits right in with your disposable, capitalistic lifestyle. Researchers at the University of Cincinnati have found a new way to utilize electrowetting, modifying the water repellency forces of a given surface to move colored ink and create a reflective display -- a technique that has long been the domain of Liquavista. This new version of that technique enables the creation of e-paper on actual paper, requiring no glass or fancy circuitry and, in theory, creating displays nearly as cheaply as magazines are printed today, opening the door to disposable e-readers and the like. No word on when such devices might be available outside of a lab, but we'll go ahead anyway and take this opportunity to remind you should always recycle your high-tech future e-readers.
