E-paper set to revolutionise our reading habits
Scientists Johan Feenstra and Rob Hayes think they've figured out how a process called electrowetting can make paper do anything a videoscreen does. So far, though, all they've got to show for their efforts is a tiny piece of e-paper one centimetre square only 225 pixels, or picture elements. That won't be nearly enough for headlines and news videos.
The only hint of the technology's potential is a laptop presentation the inventors have rigged up. It features Professor Snape, Harry Potter's potions teacher, holding an electronic newspaper with an embedded video clip. "That's what we want," says Hayes.
