Nanotubes Start to Show their Promise
Rei writes "Researchers at the University of Texas at Dallas have developed the highest quality nanotube sheets to date (the team previously set strength records with polymer-nanotube composites). Producable at a rate comparable to commercial wool spinning, the transparent cloth has exceedingly high conductivity, flexibility, has huge surface area to volume ratios, can potentially be made into very effective OLEDs and thin-film photovoltaic cells, and outperforms even our best bulk materials (such as Mylar and Kevlar) at strength normalized to weight. It strongly absorbs microwaves for localized heating (leading to applications in seamless microwave welding of sections and even windshield warming), changes conductivity little over a wide temperature range (very useful in sensors), and is expected to be used in commercial applications very soon. The research should even be expandable to artificial muscles! To head people off, while the exact tensile strength is not listed, it sounds like it is still far from the >100 GPa needed for a space elevator. Anyways, here's to process advancements!" -
Space Elevator Update
TheMadReaper writes "The 2005 edition of the Space Exploration Conference in Albuquerque, NM came to a conclusion earlier this week. A large fraction of the conference was devoted to the Space Elevator. Surprisingly, there hasn't been much news coverage of this conference, perhaps because it doesn't have Space Elevator in its name. The most interesting fact I got from the conference is that money is really starting to exist in the space elevator world mainly thanks to the work of Dr. Bradley Edwards at ISR and at Carbon Designs, Inc. The strong nanotube talk was also more promising than last year." -
Space Elevator Prizes Proposed
colonist writes "Space elevator proponents are planning competitions for space elevator technologies, similar to the Ansari X Prize. Elevator:2010 will organize annual competitions for climbers, ribbons and power-beaming systems. In other space elevator news, researcher Bradley C. Edwards recently left the Institute for Scientific Research to work at two companies on materials and technology. Also, the space elevator has caught the interest of Google's founders: 'At a space camp in Alabama last year, Brin talked about creating a space elevator to transport cargo up a special tether attached to earth. Also last year, Brin joined Page in proclaiming they should found a nanotech lab at Google.'" -
Notes From 3rd Annual Space Elevator Conference
colonist writes "The Space Elevator: 3rd Annual International Conference was held recently. Blaise Gassend, a PhD student at MIT, took notes. The main obstacle is still the material: transferring the strength of the nanotube to the ribbon. Other topics include: the nanotube tether Centennial Challenge; Elevator 2010, a challenge for a 250 kg climber to climb a 16 km tether; objections and refinements to Bradley Edwards' design; non-equatorial space elevators; replacing the term 'space elevator' with 'space bridge'; testing the space elevator material on cable cars; science; defense and economics." -
NASA Funds Sci-Fi Technology
Michael Huang writes "Wired News profiles the NASA Institute for Advanced Concepts (NIAC), the $4 million-a-year agency most famous for Bradley Edwards' study of the space elevator. Lesser known studies include weather control, shape-shifting space suits and antimatter-powered probes to Alpha Centauri. Remember, 'if it's not risky, it's not going to get funded'." -
Space Elevators Going Up
MikShapi writes "CBC is running a new piece on the Space Elevator. Nothing dramatically new, as we're all still waiting for one of the many Carbon Nanotube research centers to announce they reached the famous 100GPa red line from page 10 of the NIAC Phase 2 Report, thus obtaining 'unobtainium' [pun intended], the material necessary to build the Elevator. The report predicts this will happen during the course of the next two years or so. It's then that the fun really starts - A REAL all-out space race, open to everyone with will and a national budget, winner probably getting to own space [read last paragraph]. In the meanwhile, we can all spread the word, discuss, debate and brainstorm every nook and cranny of the program here on Slashdot, and give Edwards a shoulder by giving the program every bit of mass-exposure we can." -
Space Elevator Conference Wraps Up
slavitos writes "The Space Elevator: 2nd International Conference, organized by the Los Alamos National Lab and the Institute for Scientific Research has just finished its work in New Mexico. To be sure, most people still think it's absolutely ridiculous to even consider building such a thing. However, that's exactly what organizers wanted - an open discussion on the issue, plus some free PR." -
