Carbon Nanotubes: Now in your memory

by on May.25, 2011, under Articles, Computers, Information Technology, News, Science, Technology

Low power memory from nanotubes by Katherine Bourzac [Technology review] via [Kurzweil]

So one of the biggest problems with our emerging mobile technology is finding energy efficient nonvolatile memory. That is memory that continues to hold information even after the power is turned off. The problem is that writing to standard flash memory takes up a proportionally large amount of energy but flash memory is also some of our smallest memory to date. Carbon Nanotubes, when combined with a new type of memory called phase-change memory, may be the key to overcoming this obstacle.

Carbon Nanotubes! Now with more energy!

by on Sep.15, 2009, under Articles, Computers, Science, Technology

A photovoltaic cell made from a single carbon nanotube that can take advantage of more of the energy in light than conventional photovoltaics has been created by Cornell University researchers.

Superefficient Solar from Nanotubes by Katherine Bourzac (Technology Review)

Yes thats right. Carbon nantobues are going to make computers faster, give us lung cancer, cure lung cancer, and give us unlimited “free” energy!

Okay peoples. That is my backlog of Carbon Nanotube news. So things will be slower now as the sudden explosion of discoveries seems to have tampered off to about once a week, rather than once a day. But as you can see, Carbon Nanotubes will be a savior and our destruction! All shall love and despair!
