In honor of the Copenhagen conference, here’s a tidbit of green-tech news…
Maybe a energy storage breakthrough is around the corner:
Ordinary paper could one day be used as a lightweight battery to power the devices that are now enabling the printed word to be eclipsed by e-mail, e-books and online news.
The same feature that helps ink adhere to paper allows it to hold on to … single-walled carbon nanotubes and silver nanowire films. Earlier research found that silicon nanowires could be used to make batteries 10 times as powerful as lithium-ion batteries now used to power devices such as laplop computers.
