Real-life “landspeeder” prototype

Real-life “landspeeder” prototype

Noah Shactman just brought Israeli defense contractor Urban Aeronautics’ AirMule VTOL UAV project to my attention. The photo released by Urban Aeronautics, shown above, purports to show the first successful hovering flight of an AirMule prototype, secured against wandering off by guy-wires. Video would’ve been more persuasive. The design goal of the AirMule project is to produce an unmanned vehicle that can be used to ferry supplies into, or wounder soldiers out of, a hostile, closely-packed urban combat environment.

Make paper conductive using simple carbon nanotube ink

Make paper conductive using simple carbon nanotube ink

Ordinary copy paper can be made highly conductive by treating it with a simple water-based dispersion of carbon nanotubes. Bing Hu and other graduate students under Stanford researcher Yi Cui published a paper in Proceedings of the National Academy of Sciences of the United States of America (PNAS) describing the use of such conductive paper to create high-performing prototype supercapacitors, batteries, and fuel cells. He also studied the wear resistance of the nanotube ink and found that it bonds very tightly to the paper; his data show that soaking, rinsing, and wringing-out in water does not significantly affect the properties of the treated paper. The supplementary information for his PNAS paper is freely available for download and describes his experimental methods in detail, including the recipe for his ink and the trick of reloading a commercial highlighter with it.

Researchers create golden aluminum, black platinum, blue silver

Researchers create golden aluminum, black platinum, blue silver

University of Rochester Associate Processor Chunlei Guo has developed a technique that uses a femtosecond laser to blast nanoscale features into the surface of a piece of metal–pretty much any metal. These tiny features interact selectively with white light to reflect a particular color–pretty much any color. It’s also possible to achieve a near-perfect black finish and iridescence. If the process can be made economical (it’s very slow at present, requiring about half an hour to treat a dime-sized area), it could be a complete game-changer when it comes to finishing metals. Guo gives the example of a bicycle factory that could use only a single laser to make parts of any color or color scheme.

Thorium as the future of nuclear power?

Thorium as the future of nuclear power?

Interesting article over on Wired about Kirk Sorensen and the community served by his Energy From Thorium blog. To hear these people tell it, Thorium fission in fluid fuel reactors offers an idyllic vision of a boundless-energy-from-the-atom type future no one has really believed in since the early 50s. Thorium, reportedly, is abundant, safe, highly efficient as a nuclear fuel, and produces waste that is radioactive only for a few hundred years instead of tens of thousands. Also, the waste products from the Thorium cycle cannot be reprocessed to make bombs, which is the sole reason why it was not chosen as the basis for American nuclear energy technologies back in the 50s.

Drone hacking

Drone hacking

Drone hacking? Really? With off the shelf software? Militants in Iraq have used $26 off-the-shelf software to intercept live video feeds from U.S. Predator drones, potentially providing them with information they need to evade or monitor U.S. military operations. Senior defense and intelligence officials said Iranian-backed insurgents intercepted the video feeds by taking advantage of […]

What technology *don’t* you use?

Interesting mind stretching video with Kevin Kelly… via Kottke– I’m interested in how people personally decide to refuse a technology. I’m interested in that process, because I think that will happen more and more as the number of technologies keep increasing. The only way we can sort our identity is by not using technology. We’re […]
