Taiwanese researchers have developed a form of electronic paper that can be erased and reused up to 260 times. Not the same kind of e-paper as current e-book readers use, this is paper that can be printed on a thermal printer, then erased by plugging it into electrical current.
"In many cases, such as transportation tickets or ID badges, it will save you from printing the same thing 259 times. In terms of environmental production, this is very meaningful."
An A4-sized piece of this paper costs approximately $2. Its developers hope to have it available to consumers within two years.
