Space Jackets Down to Earth 87
Roland Piquepaille writes "Several technologies used to design the space suits protecting astronauts are now being adapted to protect workers facing extremely hot and dangerous conditions. According to the European Space Agency (ESA), these 'space-cooled' jackets are using three different technologies: special 3D-textile structure, cooling apparatus derived from astronauts' suits, and a special water-binding polymer acting as a coating. Even if these protective clothes are primarily intended for firefighters or steel workers, several applications are possible, such as in sportswear or in cars as parts of air conditioning systems.

Indeed, it is likely we will see clothing such as this used by firefighters quite soon, for instance. While that isn't everybody, it would start to bring such textiles into everyday usage.
If such materials are too expensive to be used for consumer-grade clothing, we may initially see it used for items such as cooking gloves. Eventually the technology will be developed further, and likely will become economically feasible for widespread use.
If I had to make a guess as to how long it would take, I would be inclined to think three to five years for more generalized applications, and widespread availability no more than five years after that.

Could it also be because we've realized that there's actually not a hell of a lot out there to explore? In the 1960's everyone was so excited about space because we'd never made it that far off the planet, but now that it's been done... there's not a lot to do out there except keep some interesting zero-g science experiments running. (It is a vaccuum after all... by definition, somewhat empty of interesting stimuli.)
The next important milestone in space exploration will be getting a man to Mars (and back). However, the technical problems in doing so are vastly more difficult than getting to the Moon, and that was hard enough as it is. And the fact is, once we get there, there's nothing financially benificial in it, so there's hardly a commercial reason to pursue this goal, except tourism, perhaps, but I doubt that tourism dollars can possibly fund a trip to Mars.
I'm as disapointed as you are. I really hope to see a man on Mars within my lifetime, I think this would be absolutely fantastic. However I think it's a bit of an oversimplification to say that we haven't done anything merely because we're "scared of space".
Not just clothing. Computer cooling systems. (Score:1, Interesting)
Even more importantly, such tubing could prove very useful for massive data centres or hosting complexes. The heat from computers could be collected and put to other uses. Some have theorized that it could even be used to generate power, if not used to heat rooms.
Of course, there are many non-computing uses for such a material. It could prove very useful in automobile engines, helping to keep certain components cool while also being used to pipe unwanted heat away from other machinery.
And beyond that, heating ducts made of such a material may prove useful in homes. If they manage to retain the heat better than existing ducting, we could see a tremendous drop in home heating expenses. Likewise, curtains made of this material may further help keep homes in hot climates colder, by insulating against heat.

You should know that there are modern methods of combating flash over. The first is to ventilate the structure and the second is to use short burst of spray from a 60 degree fog nozzle which cools the unburned particles of combustion (aka smoke) just enough to eliminate flashing but not so much that the smoke banks downward. The latter is known as the 'Swiss' method because it was developed by Swiss engineers and firefighters.
You should also know that leather boots are not recommended for structure firefighting by the NFPA. Your department should be wearing bunker boots, we wore Fire-Walker bunker boots made by Ranger Footwear, and Nomex pants jackets and hoods.
I don't know of a fire department anywhere that still wears 'traditional' firefighting helmets with leather ear protectors, except yours, I guess. Most department have been wearing composite helmets with face shields and Nomex ear protectors.
Everything I've described here is 'old' technology.
Oh, and sticking a pick-headed ax in a wall, tying a rope to it and jumping out a window to escape a flash over? Sounds like something someone pulled out of their ass.
By the way, over a 24 year period I was a Firefighter I, II, III, Firefighter/Paramedic, Fire Specialist, Fire Engineer and Engine Company Captain. I've been retired for 8 years.
RTFA -- it claims to protect you from flashover. (Score:5, Interesting)
The story (and Slashdot isn't the place I read it first -- I think Science Daily covered it earlier in the day) claims the suit will protect firefighters during flashover.
If you've cooled the overhead there IS NO flashover. If you've vented right, there is no flashover.
If someone doing a search gets too hot and decides to break a window before you're ready to vent -- you may set the stage for something that this suit is NOT going to help protect you from. THATS my point.
As to using a pick headed axe to get out? Putting the Axe across the corner of the window and using your own weight to hold it while you bail is a well known practice. I've done it in training, from a second floor, with a blindfold (and a safety line). I've done it over, and over, and over. I've done it using a figure 8 and my built in harness, and I've done it without a figure 8 just looping the rope around my back and using my gloved hands for the friction device.
On your last comment, my copy of the NFPA Essentials guide is 3 feet to my right.
I'm a firefighter, and I hope this works (Score:4, Interesting)
There are a couple of major issues that this technology might address that would be helpful.
1) At hazmat incidents, turnout gear is frequently inappropriate. The people doing the hot zone work are in "level 1" suits, which are fully encapsulated. However, level 1 suits are HOT, and level 1 techs are hard to come by. This might make it easier for level 1 techs to stay in the hot zone for longer periods of time or perform more evolutions.
2) For my brother firefighter who pointed out that structural firefighting gear including nomex hoods provide inadequate protection for flashover (or getting steamed by the idiot outside who started squirting when we're inside), imagine having a level-1 type of setup for fighting fire. Your hands and head are no longer the most vulnerable because with this new technology your whole body is being cooled actively. I realize that level 1 is bulky and wouldn't be appropriate NOW, but if the technology is available someone will figure out a way...
3) Barn fires in August just KILL crews. If you're standing outside in the sun for any length of time in turnout gear, you get completely baked. This might make it easier for us to endure fires in summer.
4) Brush fires suck. SOG for departments that don't have nomex jumpers for fighting brush fires are to wear FF boots, turnout pants, and gloves. So you're slogging around through chest-high red brush getting cut to hell, a mile off the road, getting your ass kicked in your heavy gear, taking a shovel, axe, or if you're a rookie an Indian Can strapped to your back. Again, it doesn't take long to get overheated. Maybe not any longer.
I hope that the technology performs. I'm whipped.
