The problem with earthquake -proofing a building is that it usually involves grafting on a lot of support — not really an option with historic buildings or other particularly delicate structures. Komatsu Seiren Fabric Laboratory might have a better way, however. Its carbon fiber-based CABKOMA Strand Rods can protect a building against quakes by tying the roof to the ground, making sure that the whole building moves together — and thus stays together — during a tremor. The fibers are both very strong and very light (you can easily carry a 520-foot strand by yourself), so it’s more like draping spiderwebs over a building than anchors. As you might have gathered just by looking at the photo above, the technology has its limits. It won’t work for tall buildings, or those in dense urban areas where there’s simply no room. This is more for mid-size structures that have plenty of free space. All the same, it might be the key to saving lives in areas where conventional bolts and braces just won’t work.

Zothecula writes: Radically cheaper, quicker and less energy-intensive to produce than regular steel, Flash Bainite is stronger than titanium by weight, and ductile enough to be pressed into shape while cold without thinning or cracking. It’s now being tested by three of the world’s five largest car manufacturers, who are finding they can produce thinner structural car components that are between 30-50 percent lighter and cheaper than the steel they’ve been using, while maintaining the same performance is crash tests. Grain of salt: the positive claims here are mostly coming from the company responsible for the process. Read more of this story at Slashdot. 
szczys writes: Carbon Nanotubes and Graphene breakthroughs pop up in the news often enough for them to be considered buzzwords. Most of the time it’s the superconducting properties of graphene that are touted, but molecule-scale structures also hold the promise of building mechanical computing devices that are unimaginably small. The reason we don’t have these things yet comes down to the manufacturing process. Building machines out of carbon molecules is commonly called Rod Logic — a topic many know from the seminal novel The Diamond Age. Al Williams discusses how Rod Logic works and highlights some of the places we’re already seeing these materials like to help cool LED light bulbs, and to strengthen composites.

KentuckyFC writes Physicists at the Max Planck Institute for Chemistry in Germany have measured sulfur hydride superconducting at 190 Kelvin or -83 degrees Centigrade, albeit at a pressure of 150 gigapascals, about the half that at the Earth’s core. If confirmed, that’s a significant improvement over the existing high pressure record of 164 kelvin. But that’s not why this breakthrough is so important. Until now, all known high temperature superconductors have been ceramic mixes of materials such as copper, oxygen lithium, and so on, in which physicists do not yet understand how superconductivity works. By contrast, sulfur hydride is a conventional superconductor that is described by the BCS theory of superconductivity first proposed in 1957 and now well understood. Most physicists had thought that BCS theory somehow forbids high temperature superconductivity–the current BCS record-holder is magnesium diboride, which superconducts at just 39 Kelvin. Sulfur hydride smashes this record and will focus attention on other hydrogen-bearing materials that might superconduct at even higher temperatures. The team behind this work point to fullerenes, aromatic hydrocarbons and graphane as potential targets. And they suggest that instead of using high pressures to initiate superconductivity, other techniques such as doping, might work instead. Read more of this story at Slashdot. 
Hydrogen fuel cells are a cool technology that were perfected to enable humans to go to the moon. Now that they’re perfected even more, they’re enabling humans to go to work or the liquor store, and, incredibly, this is progress. The Toyota Mirai is an example of this remarkable progress. Funny looking, maybe, but it works. Read more…
