A sultry day was in the offing near Purnell OK, the seat of McCurtain County in the state’s southeast quadrant, just a dozen miles northwest from the triple point where Arkansas, Texas and Oklahoma meet. One hundred forty miles northeast, the National Weather Service Doppler radar station KSRX at Ft. Smith Arkansas, was monitoring a cold front approaching from the west, driven by a mass of cool dry air sweeping down from the northern plains. Typical for the late spring in the American prairie, this eastbound mass was colliding with a warm, wet air mass streaming north from the Gulf of Mexico, now roiling under a cool dry tongue at 700 mb. Buoyant but trapped under heavier cool air, supercells were forming in the humid 850 mb surface layer twenty miles west of Purnell.

Hat to helmet in nanoseconds: Shear Thickening Fluids (STF) – nanotech liquid

Shear Thickening Fluids (STFs) may be “liquid” in a strict sense – but they’re used in fabrics. Developed by Professor Norman Wagner and his research team, including students, of the University of Delaware, as a joint project between the University of Delaware Center for Composite Materials and the United States Army Research Lab. They’re amazing – and are already in use. (Professor Wagner seems a bit shy, but very proud of his students. The website for his research group is filled with photos of his colleagues, graduate students and undergraduates – but what should be his personal page on the University of Delaware site is a dead link). STFs are added to Kevlar, making ballistic armor more effective;

D30 Labs has been making STF’s available to the civilian market. The Swiss Company RibCap has been making what look like normal knit caps – soft until subjected to a sudden force – at which time they behave like crash helmets:

At the moment not, apparently, available in the United States – but they’re available via some Canadian and British stores .Ribcap’s Swiss site here; their Canadian affiliate, DirtSurfer, also has a list of U.S. retailers.

We’d like to know more – and see test data – but if effective, these soft hats should be in every go-bag – and worn by every emergency responder who’s not already wearing protective headgear.

6-in-1 Utilikey from SwissTechTools.com/at Container Store

6-in-1 Utilikey from SwissTechTools.com

6-in-1 Utilikey from SwissTechTools.com

Picked up this Utilikey 6-in-1 tool at one of the local outlets of the Container Store. It weighs half an ounce (0.5 oz; 14 mg.) and has six features:

– Flat Screwdriver

– Phillips Screwdriver

– Micro Eyeglass Screwdriver

– Straight Blade Knife

– Serrated Blade Knife

– Bottle Opener

It locks and unlock easily, seems quite sturdy and precisely machined, and there’s enough dull surface area to grab with the blades open that it can be held securely and used with some force.

There’s an 8-in-1 model which includes a wire cutter and wire stripper, but we haven’t seen or tested a sample.

If you’re carrying just house keys, it’s still small and light enough not to be in the way. This one looks like a must-have, and perhaps a good item for bulk purchase by community-based preparedness organization.

Note: we assume that you’re all already carrying portable flashlights.

Available at The Container Store, but not, apparently, on their website.

On Amazon, Swiss Tech UKTBS Utili-Key 6-in-1 Polished Stainless Steel Key Ring Multi-Tool.

Conflict of interest disclosure: we receive, in theory, a small commission on any sales via Amazon.

Unplggd/Apartment Therapy: 5 flashlights

Unplggd has a flashlight roundup

– several are plugin-constant standby – one solar powered, one hand-cranked. All worth a look. However, I’m not giving away my Safe-Light anytime soon , and in fact have been considering purchasing them in bulk. Have done some stupid things – like drive long distances without a flashlight or jumper cables – but I change batteries about once a year.

They’ve got a number of variations on the same idea – if you’re going to carry one, though, I’d recommend The Safe-Light Super Bright With Coloured LED- in red – as the best way to see and

maintain your night vision in an emergency.

Portable water container – from Toolmonger

Their focus, of course, is different from ours, but Toolmonger is an incredible site – often showing emergency response/reconstruction tools we’d never hear of otherwise. Here’s one the Rol-La-Tank: (or Fol-Da-Tank, which might be the company name, or the name of the product line). They’ve got both URL’s Foldatank.com and Fol-Da-Tank – this should give interested readers enough to find them.

Kevin Kelly on Mosquito Netting

In watching the deluge in the Midwest, I’m remembering a description of the post-Katrina proliferation of dragonflies – a fortuitous turn that stopped the mosquito population from getting out of control. One robust response is mosquito netting, and this piece is from his excellent blog Cool Tools:

I hate mosquitoes. Serious gut-tightening allergic aversion. One bite at night and I am awake for hours, and I’ll itch for days. They’ll always find me, too. I’ve learned to ignore what natives say; there are mosquitoes around, and they do bite. When I travel in any remotely warm place, I pack my own mosquito netting. It weighs only a few ounces and can scrunch up small. It’s cheap, and lasts forever. I’m still using one I bought 30 years ago for $2. I like the boxy four-cornered variety to fit over a bed or sleeping bag. I tie a 6-foot long string to each corner; that usually enables me to attach the string somewhere to keep the net elevated at night. I tie it to trees if I am camping without a tent.

I haven’t figured out why more people don’t pack their own. Mine has saved my life more than once. Mostly by allowing me to sleep soundly, but also because with it I avoid mosquito-borne diseases in areas they are common. Studies have shown that sleeping in a net is more effective at preventing malaria than taking prophylactic drugs. I insist my family use netting while we travel in the heat overseas. A quick search led me to Coleman as the least expensive source for a one-person camp-style box net.

I’m afraid that mosquito netting may be added to the list of things that FEMA won’t provide – although if FEMA puts itself out of business by zeroing out that list, we’ll be forced to address the issue – federally and otherwise.

LiquidReflector – reflective paint

Liquid Reflector is a reflective paint – available in five colors and a clear version, and, according to the manufacturer, yields a fine surface and high reflectivity. (Note: the reflected light is white, regardless of the visible color on the surface). We’d like to test some of this – see how it holds up – and whether its reflectivity would be affected by polyurethane or other transparent protective sealants.

The elegance of reflective materials, of course, is that they’re not dependent on electricity, and, wherever placed, they work when/as needed.

Atlas Powered Rope Ascender

The Atlas Ascender – is a powered rope or cable ascender/descender capable of, for instance,

  • equipment hauling
  • military special operations (rapidly and quietly scaling a building
  • rescue operations (capable of retrieving casualty in litter and rescuer)

This image doesn’t do it justice. There’s a video clip on the Atlas site .  The inventor was an MIT student when he developed this – reportedly as an entry in a DOD-sponsored competition.

Rescue Streamer – exceptionally well-designed emergency signal device

We’ll have a longer post later, but for now, we’ll say that the Rescue Streamer is brilliant. This tiny (when stored) banner greatly increases the probability of being seen from overhead – one doesn’t need to apply Bayes’ theorem to figure that out – and also has the following attributes:

  • not subject to battery failure
  • no training required
  • no fuel required (as in triangles of signal fires)
  • no fire starting required – and no risk of, for instance, starting a forest fire – when what you really wanted was to be rescued
  • not prohibitively expensive (by any stretch of the imagination)
  • works on land and water

Safe, non-toxic, effective, inexpensive, easy to use. Apart from our interest in emergency preparedness, this is a fantastic example of excellent engineering.

We hope to be following up shortly with photographs and more information about the development of the Rescue Streamer.
