Goodbye Mr. Chips?
I'm Bob Karson with the discovery files--new advances in science and engineering from the National Science Foundation.
A major milestone in technical innovation, thanks to the work of a team of Stanford engineers. They have built and successfully tested the world's first computer based on carbon nanotube technology instead of silicon chips; could be the birth of a new generation of electronic devices that run substantially faster, cooler and more energy-efficiently.
For decades, progress in electronics has meant shrinking the size of transistors to pack more on a chip. But as transistors become tinier they waste more power and generate more heat--enough to give you a case of: "Lap burn" (Sound effect: ouch!) you've felt it with your own laptop.
Using carbon nanotubes instead of silicon chips means more efficient conductors, so thin you can fit a ton of them in a small space: Thousands fit in the width of a human hair (Sound effect: cartoon hair pluck). It takes less energy to switch them off and they run a lot cooler.
The researchers' carbon nanotube computer can count and do number sorting, and is able to switch between the two. Hey, it's a start. They hope others will be inspired by this breakthrough to help develop this new kind of computer technology for the future. Faster, better, smaller, cooler. "nano-tubular".
