U.S. Army Testing Personal Cooling Suits
DJ BenBen writes to tell us that they Army is currently testing some 500 liquid cooled vests with Humvee crews in Iraq. From the article: "The Humvees with add-on armor were fitted with air conditioners after TARDEC engineers in Warren, Mich., were given the requirement to figure out how Soldiers in armored vehicles could be kept cool under the desert sun. Some of the same engineers had designed the add-on armor kits for the M-998 and M-1025 Humvees in theater. But with the extra armor and doors closed, temperatures inside the vehicles could reportedly reach more than 130 degrees. 'It's like putting somebody in a toaster oven on low heat,' said Charlie Bussee, an engineer at TARDEC."
Is it such a good idea to 'Slashdot' a MILITARY website?
Lets hope they don't hit back....
DEAD DEAD DEAD DELETE ME
And exactly why would you ask scientists and engineers in MICHIGAN to test the effect of a DESERT environment? Utah I could understand. Or Nevada. Or Arizona. Or New Mexico. But Michigan?

Possibly, but it's got to be better than dying of heatstroke.
Personally, I'd say being in Iraq is bad for American soldiers' health... but that's just me.
I don't care if it's 90,000 hectares. That lake was not my doing.
What it takes to get them home safely: stop declaring war on people. :P
I don't know if this is such a good idea..when I was in Afghanistan we often were in humvees and they were already crammed as it is. I think anything like this would just add to the chaos that is inside the humvee. Although it is a step in the right direction It just dosn't seem smart. Its hard to get out of a humvee when you plan to, and I can't imagine how bad this might add to any reaction to contact or IED. The Ac in humvees right now is not too bad, its just the fact that it overheats the engine and you end up having to shut it off is what sucks. Then again, its always cool up top on the turret...

Okay, yes, a coolsuit isn't news for some. What I take issue with is that you seem to have taken the same, unfortunate belief that so many smart people fall into. Military development isn't cheap, and because all the exact details are rarely given out to the public, it's assumed to be mostly waste. While this may be true in some cases, it's not the norm. Believe it or not, the Army does have a limited budget and actually cares about researching many areas simultaneously; thus they do care about waste.
Anyway, there's always a difference between a commercial technology and a military one. Take this suit for example. How many times do you think racecar drivers get shot at while in their cars? If a bullet penetrates through, what will the results be? If there is fluid leakage, will it harm internal tissue or poison the blood stream, or is it so cold that muscles will tense up? If there are wires (and there are), could those short out and cause electrical damage to the wearer? If the system becomes non-functioning, what could happen that would prevent the wearer from continuing the mission? Lastly, what do the soldiers that will be issued this device think about it? You know, the guys that have been there, and will be going back? Yep, the Army gets everyone's input (even privates), and that's a huge benefit mostly unique to our military.
As someone that's in the Army, I can tell you that we don't get issued ANYTHING unless the leadership is confident that it will benefit our mission. That's not a bad thing.
Long, cute, or funny Sigs are just another form of over compensation, used by geeks, nerdz, etc.
Do what they do to deal with the heat. Instead of $5000 air conditioned suits, consider wearing a shawez kameez or other clothing that has been developed by the locals over a thousand years to deal with the climate.
Yeah, because the natives drive around in heavily armored humvees all day long, right? Personally, I know that sitting in a slow moving car, with the windows down, in the Texas sun in the middle of the summer is quite hot. What is it going to be like if you raise the temperature and decrease the ventilation?
I believe they will require some active cooling.
I was going to let this thread go but this post kinda hit my buttons. Normally, I wouldnt reply to an anonymous coward, but I defend this individuals right to spew whatever he wants as an anonymous coward.
First -- 130 degrees? Where were they testing this thing, Michigan in August? It regularly hits 110-120 in that area of the world. Going on the 35 degree temp spread as mentioned in the article, we are talking 110 outside, 145+ inside... Hmmmmm
Second -- Can you deal with the personal discomfort of a field environment, temps regularly hitting triple digits (Im talking outdoors, not in a tactical vehicle, Tacticle vehicles, you will yearn for 90 after 10 mins on one of them), combat stress of random bullets flying around? This poster probabally has a nice and cushy desk job in a safe, air-conditioned office somewhere. If so, the cold is causing this person to forget something interesting:
When was the last time the USA has fought any type of conflict in a desert environment FOR A SUSTAINED PERIOD. Desert Shield/Storm was quick in the grand scheme of things. Most of our conflicts were in a tropical or continental type of environment (continental I mean grassy/forests... not desert or rainforest extremes). We have not had to deal with any type of sustained combat operations in a desert environment.
The stresses that are experienced by both our equipment and Troops out there have forced a major rethinking of strategy and equipping of our personnel to address these climatic extremes. I think AC units in these HMMWV's are a nifty idea, but not necessarially a good one due to the cost of maintaining one in a piece of equipment like this, in the environment that they serve in. Same extends to these vests, good idea in theory, lets see how well this equipment lasts when our fightin boys beat this equipment up. Yes, they take care of it because its their lifeline, but we will see how they handle the combat stresses endured in daily operations. I hope it works, because we need this type of gear and a conflict like this is allowing our best and brightest in this country to think outside of the box to provide us with equipment that will make life a little more tolerable.
So In closing anonymous coward; YOU enjoy your air-conditioning and cushy life... Maybe if you want an idea of how we feel, without stressing your self out too badly... Wear a 3 piece suit (Its about as heavy as the utility uniform). Drive to work when its nice and hot outside (80+ stateside should do the trick) with your windows cracked and your heat on full blast... You will get an idea of what we deal with. Oh, add the body armor, 3 weeks of stink from not taking a shower, oh and bullets, yes bullets flying at you randomly. You will have somewhat of a clue what is dealt with. Are these ideas perfect? Hell no... But it is a logical idea that cant hurt at this point. Robert Active Duty Marine Maintenance Management Specialist My comments do not reflect that of the US Government or Marine Corps.
