Battery Saver

PostedApril 10, 2011


Randy Atkins: In electronic devices, a lot of power is drained by shuttling information to silicon memory chips. So Eric Pop, a University of Illinois engineering professor, has used carbon nanotubes – ten-thousand times smaller than a human hair – to activate memory storage material at extremely low voltages.

Eric Pop: We’ve been able to make this about a hundred times more energy efficient and about a hundred times faster than anything in industry today.

Randy Atkins: Pop thinks they could make it even better, but manufacturing hurdles remain.

Eric Pop: Nobody has figured out a way to integrate them at the scale of a billion nanotubes per chip the way we do with silicon today.

Randy Atkins: But Pop believes that’s only a matter of time. With the National Academy of Engineering, Randy Atkins, WTOP News.
