QotD: Microfibres and innovation
New and improved fabric technologies haven’t attracted public enthusiasm since the backlash against leisure suits and disco shirts made synthetics declassé in the early 1980s. ‘Pity poor polyester. People pick on it,’ wrote The Wall Street Journal’s Ronald Alsop in 1982, describing DuPont’s efforts to rehabilitate the fibre’s image.
What ended the consumer hatred of polyester wasn’t a marketing campaign. It was a quiet series of technical innovations: the development of microfibres. These are synthetics, most often polyester or nylon, that are thinner than silk and incredibly soft, as well as lightweight, strong, washable and quick-drying. Their shapes can be engineered to control how water vapour and heat pass through the fabric or to create microcapsules to add sunscreen, antimicrobial agents or insect repellent. Over the past decade, microfibres have become ubiquitous; they’re found in everything from wickable workout wear to supersoft plush toys.
Microfibres are one reason the ‘air-conditioned’ fabrics Loewy and his fellow designers foresaw in 1939 have finally come to pass. These fabrics just aren’t promoted in the pages of Vogue or highlighted on the racks at Banana Republic. They don’t attract attention during New York Fashion Week. Their tribe gathers instead at the big Outdoor Retailer trade shows held twice a year in Salt Lake City. There, outdoor-apparel makers and their suppliers tout textiles that keep wearers warm in the cold and cool in the heat; that block raindrops but allow sweat to escape; that repel insects, screen out UV rays and control odour. By establishing that truly weather-resistant fabrics were possible, Gore-Tex (first sold in 1976) and Polartec synthetic fleece (1979) created an industry where engineers now vie to find ever-better ways to conquer the elements. For instance, ‘smart textiles’ originally developed for spacesuits use microencapsulated materials that melt when they get hot, keeping wearers comfortable by absorbing body heat; when temperatures fall, the materials solidify and warm the body.
[…]
Looking forward, academic researchers have bigger things in mind. Noting that ‘a large portion of energy continues to be wasted on heating empty space and non‑human objects,’ the materials scientist Yi Cui and his colleagues at Stanford envision replacing central heating systems with ‘personal thermal management’, using breathable fabrics coated in a solution of silver nanowires. The fabrics not only trap body heat: given an imperceptible bit of electric charge, they can actually warm the skin.
Other scientists are looking at ways to make fabric turn body heat or motion into usable energy for low-powered electronics. And some hope to make the temperature-regulating effects of smart textiles work without liquids, whose microencapsulation requires substantial energy use. Shifting the focus from outdoor leisure to indoor life – from fighting the elements to everyday energy use and climate control – dramatically reframes several decades of fabric advances, making textiles part of a larger story about energy and the environment.

QotD: 1815’s other triumph
[In] 1815, George Stephenson, a humble, self-taught engine-wright with an impenetrable Geordie accent (to which he probably gave the name), put together all the key inventions that — at last — made steam locomotion practicable: the smooth wheels, counter-intuitively less likely to slip if heavily laden; the steam-blast into the chimney to accelerate the draught over the coals; the vertical cylinders connecting directly with the wheels; the connecting rods between the wheels. A year later came his redesign of rails themselves, then later his multi-tubular boiler.
As his biographer, Samuel Smiles, put it:
“Thus, in the year 1815, Mr Stephenson, by dint of patient and persevering labour … had succeeded in manufacturing an engine which … as a mechanical contrivance, contained the germ of all that has since been effected. It may in fact be regarded as the type of the present locomotive engine.”
Suddenly the movement of goods and people fast and cheaply over long distances became possible for the first time.
Not content with that, in 1815 Stephenson also invented the miner’s safety lamp (though snobbish London grandees, unable to conceive that such a humble man could have done so, gave and have continued to this day to give the credit to Sir Humphry Davy). The year of Waterloo was an annus mirabilis of the industrial revolution, putting Britain on course to dominate and transform the world, whether we beat Boney or not. Steam, followed by its offspring internal combustion and electricity, would catapult humankind into prosperity.
Incidentally, there is a tenuous connection between Napoleon and Stephenson. If Bonaparte’s conquests and the corn laws had not driven up the price of corn, then horse feed would have been cheaper and the coal owners who employed Stephenson would not have risked so much money in letting him build a machine to try to find a less expensive way to pull wagons of coals from the pithead in Killingworth to the staithes on the Tyne.

“Crafting. Needs. To. End. It is ruining gaming”

QotD: Fabric as technology
In February 1939, Vogue ran a major feature on the fashions of the future. Inspired by the soon-to-open New York World’s Fair, the magazine asked nine industrial designers to imagine what the people of ‘a far Tomorrow’ might wear and why. (The editors deemed fashion designers too of-the-moment for such speculations.) A mock‑up of each outfit was manufactured and photographed for a lavish nine-page colour spread.
You might have seen some of the results online: an evening dress with a see-through net top and strategically placed swirls of gold braid, for instance, or a baggy men’s jumpsuit with a utility belt and halo antenna. Bloggers periodically rediscover a British newsreel of models demonstrating the outfits while a campy narrator (‘Oh, swish!’) makes laboured jokes. The silly get‑ups are always good for self-satisfied smirks. What dopes those old-time prognosticators were!
The ridicule is unfair. Anticipating climate-controlled interiors, greater nudity, more athleticism, more travel and simpler wardrobes, the designers actually got a lot of trends right. Besides, the mock‑ups don’t reveal what really made the predicted fashions futuristic. Looking only at the pictures, you can’t detect the most prominent technological theme.
‘The important improvements and innovations in clothes for the World of Tomorrow will be in the fabrics themselves,’ declared Raymond Loewy, one of the Vogue contributors. His fellow visionaries agreed. Every single one talked about textile advances. Many of their designs specified yet-to-be-invented materials that could adjust to temperature, change colour or be crushed into suitcases without wrinkling. Without exception, everyone foretelling the ‘World of Tomorrow’ believed that an exciting future meant innovative new fabrics.
They all understood something we’ve largely forgotten: that textiles are technology, more ancient than bronze and as contemporary as nanowires. We hairless apes co-evolved with our apparel. But, to reverse Arthur C Clarke’s adage, any sufficiently familiar technology is indistinguishable from nature. It seems intuitive, obvious – so woven into the fabric of our lives that we take it for granted.

QotD: You can’t fix network security by changing the users
Every few years, a researcher replicates a security study by littering USB sticks around an organization’s grounds and waiting to see how many people pick them up and plug them in, causing the autorun function to install innocuous malware on their computers. These studies are great for making security professionals feel superior. The researchers get to demonstrate their security expertise and use the results as “teachable moments” for others. “If only everyone was more security aware and had more security training,” they say, “the Internet would be a much safer place.”
Enough of that. The problem isn’t the users: it’s that we’ve designed our computer systems’ security so badly that we demand the user do all of these counterintuitive things. Why can’t users choose easy-to-remember passwords? Why can’t they click on links in emails with wild abandon? Why can’t they plug a USB stick into a computer without facing a myriad of viruses? Why are we trying to fix the user instead of solving the underlying security problem?

Perhaps the US Navy can learn from Denmark on getting the “Little Crappy Ships” right
On the National Interest Blog, James Hasik points out that the idea of the Littoral Combat Ships of the US Navy was successfully implemented more than twenty years ago (and much more economically, too):
In contrast, we know it’s possible to get modularity right, because the Royal Danish Navy has been getting it right since the early 1990s. Way back in 1985, Danyard laid down the Flyvefisken (Flying Fish), the first of a class of 14 patrol vessels. The ships were intended to fight the Warsaw Pact on the Baltic — a sea littoral throughout, with an average depth of 180 feet, and a width nowhere greater than 120 miles. Any navy on its waters might find itself fighting surface ships, diesel submarines, rapidly ingressing aircraft, and sea mines in close order. On the budget of a country of fewer than six million people, the Danes figured that they should maximize the utility of any given ship. That meant standardizing a system of modules for flexible mission assignment. The result was the Stanflex modular payload system.
At 450 tons full load, a Flyvefisken is much smaller than a Freedom (3900 tons) or an Independence (3100 tons). Her complement is much smaller too: 19 to 29, depending on the role. At not more than 15 tons, the Stanflex modules are also smaller than the particular system designed anew for the LCSs. But a Flyvefisken came with four such slots (one forward, three aft), and a range of modules surprisingly broad […]
Swapping modules pier-side requires a few hours and a 15-ton crane. Truing the gun module takes some hours longer. Retraining the crew is another matter, but modular specialists can be swapped too. The concept has had some staying power. The Flyvefiskens served Denmark as recently as 2010. In a commercial vote of confidence, the Lithuanian Navy bought three secondhand, and the Portuguese Navy four (as well as a fifth for spare parts). Over time, the Royal Danish Navy has provided Stanflex slots and modules to all its subsequent ships: the former Niels Juel-class corvettes, the Thetis-class frigates, the Knud Rasmussen-class patrol ships, the well-regarded Absalon-class command-and-support ships, and the new Ivar Huitfeldt-class frigates.
Flyvefisken-class patrol ship HDMS Skaden (hull number P561) and HDMS Thetis (F357) in Copenhagen (via WikiMedia)
In short, 25 years ago the Danes figured out how a single ship could hunt and kill mines, submarines and surface ships. A small ship can’t do all those things well at once, but that’s a choice in fleet architecture. Whatever we think of the LCS program, we shouldn’t draw the wrong lessons from it. Why is this important? Modularity is economical, as the Danes have long known. Critically, modularity also lends flexibility in recovering from wartime surprise, in that platforms can be readily provided new payloads without starting from scratch. Because on December the 8th, when you need a face-punched plan, you’d rather be building new boxes than new whole new ships.
