It looks like a wisp of smoke or even the work of a very confused spider, but this is actually a close up of the lightest material that has ever been created.
If you generate a lot of excess body heat—and there's no shame in it—then it would make sense to put it to good use. A new wearable fabric called Power Felt could be the answer; it can generate electrical current from temperature differences.
Laser-powered carbon nanotube speakers! They'll fit in walls and windows, and can noise-cancel ambient rackets. Or blast some music.
Reading the electronic-media narrative as it plays out in many popular tech and news blogs, one would think we are hurtling toward a future where paper is all but unnecessary.
These next gen carbon nanotube muscles have "diamond-like" stiffness side to side, but are as flexible as rubber when moved perpendicularly. When voltage is applied to the structures, they contract with a pulling force 30 times the force per unit of human muscles.
Yesterday we got a peek at the combined power of nanotubes-technology that makes a rope-driven space elevator feasible-but what can just one do on its own? Berkeley researchers have discovered that one nanotube can be used as a tiny platform to determine the mass of a single atom.
In the search for that holy grail, the everlasting battery, not much has been accomplished over the 200 years since old man Volta rolled out the first crude battery back in the dark ages. Now those whiz kids at MIT are using nanotube structures to create new super batteries by using energy storage doodads called…
