Building Tomorrow's Soldier Today 230
FleaPlus writes "Wired reports on a glove developed by Stanford researchers Dennis Grahn and Craig Heller which combines a cooling system with a vacuum in order to chill blood vessels and drastically reduce fatigue. Besides the obvious military and athletics applications, the technology is also potentially useful for firefighters, stroke victims, and people with multiple sclerosis. The Wired article also describes a number of other human enhancement projects intended to advance battlefield technology. Examples include military exoskeletons, projects designed to increase cognition or decrease the need for sleep, and studies that may one day allow single soldiers to operate multiple aerial drones. Many of these were opposed by the President's Council on Bioethics."

And why not? Human beings have made themselves to be more unhuman in every passing year. We have professional athletes whose exercise programs would be considered abnormal and pointless, (not including shaving eyebrows to achieve an iota of improvement in swim speed.) We have anti-aging pharmaceutical food and beverage offerings that cater to the Baby Boomers who felt entitled to look like 40-yos instead of 60. We have daily caffeine to boost our brains in the morning, no-dose to boost productivity in the evenings, Prozac to lift us when we're low, and even psychadelic drugs to boost creativity when we're dull. We design ergonomic chairs and keyboards while we sit in front of computers and in our cars for longer hours. We alter hormones and apply suntan lotions. We use AC's and heaters so that our habitats can include the most uncomfortable places on Earth. We give our children Baby Einstein so that they will be superkids and outcompete others when they grow up.
I'm not saying it's pointless for soldiers on the frontline to receive these booster-packs. They have a job to accomplish, and so do we. Maybe we're all trying to become Homo sapiens cyberneticus too. Maybe our environment self-selects.

Actually, it reduces muscle fatigue by 'supercharging' the body's coolant system, also know as blood. You can do the same effect with much less efficiency by running cold water over the hands. We have been playing with the concept at work. I went from 15 pushups in 10 pushup sets to 55 pushups in 10 pushup sets with 2 minutes of hand cooling between sets. Yes, I am out of shape.

True. That may be solving the wrong problem.
The problem they're working on with this isn't one the US has. The "superhuman abilities" thing is useful when assaulting hard, heavily defended, hard to access targets. But the US military is very good at assaulting hard targets.
What the US military is lousy at is fighting guerrilla and insurgent movements. Those are about intelligence, not firepower. The opposition tries to avoid offering any hard targets. They don't fight pitched battles. It's classic Maoist doctrine: "The enemy advances, we retreat; the enemy camps, we harass; the enemy tires, we attack; the enemy retreats, we pursue." The US couldn't deal with that in Vietnam, and it can't deal with it in Iraq.

Oh, bullshit. Most of the ethical exploration you're referring to, particularly in Star Trek, consists of nothing more than reinforcing 19th-century moral structures applied to 20th-century situations (though allegory of 24th-century technologies.)
Homosexuals are pushing for equality in society, including rights of marriage? The message of Star trek is "cram those assholes back in the closet, where they belong. No gay people in our version of the future." People of different races want equal treatment before the law, and to be seen as individuals, not weirdos? The message of Star Trek is "You're your race. You're just a Klingon; we expect you to be violent. You're just a Ferengi, you'll never be anything but avaricious. You're just a Jew or a nigger. Only white people are normal and non-ethnic." Even the Prime Directive presents a viewpoint on developing cultures right out of 19th-century colonialism - "savages will be savages, and there's nothing we can do to help them."
Honestly it's always astounded me when people put things like Star Trek out there as some kind of ideal future of equality. What, just because every single series had one token black person on the bridge? When you really pay attention to the series you find that the attitudes are remarkably parochial and conservative. Nearly everyone in the five different series is a racist, and good luck trying to find a single gay character.

Is your sig an attempt to mock John Kerry, or President Bush?
I happen to agree with Kerry's quote. We *do* need more troops in Iraq, if we have any intention of actually accomplishing anything positive there. Unfortunately, not only is this a rather unpopular stance, it's also true that a "surge" of only 21,000 or so more troops isn't going to do the job. What we need is to go back to the original recommendations of people like Gen. Eric Shinseki, and send an additional 500,000 or more troops. Not that this will ensure success, but it's the only chance we have to make this all work out, unless we're going to take the standpoint that the situation is unsalvageable, and try to work it out by paying reparations.
We may have had no moral authority to invade Iraq, but we sure as Hell have a moral responsibility now to clean up after our mistake, no matter the cost to the United States of America. The only real question is, do we even have the ability to do it anymore?

My, that is a novel suggestion as to how the techniques of "Blitzkrieg" came into being. I suppose it should have been obvious me--it's well known that their soldiers are "fanatic" or "drug-crazed", while ours are "higly motivated".
Seriously, there's nothing new here. For example, benzedrine and other stimulants were routinely issued to U.S. Air Force pilots to keep them awake during WW II. In fact, the U.S. Air Force still issues amphetamines to its pilots and pressure them to take these "go pills". (For example, take a look at http://scotlandonsunday.scotsman.com/index.cfm?id= 1425252002 [scotsman.com] or http://www.airpower.maxwell.af.mil/airchronicles/a pj/apj97/spr97/cornum.html [af.mil] or http://www.wired.com/news/medtech/0,1286,57434,00. html [wired.com]here.
It might be interesting to ask whether the pilots who were involved in the disturbingly frequent "friendly fire" incidents during our recent ventures in Afghanistan and Iraq were flying high in more than one sense. But nobody will.

I heard of this some time ago, in the context of increasing stamina of athletes (and it wasn't a glove then, but a mini-chamber). But it occurred to me -- as someone who has trouble losing fat -- that this energy-remover might be worn for extended periods to remove a lot of calories from one's core, thus prompting the body to produce more heat, thus using more energy reserves, which is to say, fat.
Sell this on the open market as "the fat-burning pod" or something at $125 a pop and watch the cash roll in...
Re:The Glove (Score:2, Interesting)
The problem that they found is that the temperature at which maximum effectiveness of heat transfer occurs varies by individual. If the hand gets too cold, blood vessels constrict and greatly reduce the effectiveness - as in the huskies feet.
That means that there needs to be some means of regulating the temperature of the water going into the glove and some means of measuring the temperature (and thus effective heat transfer) of the water coming out of the glove. Calibration means lowering the temperature slowly until you see a significant drop in water temperature change across the glove. A degree or so above that would max out heat transfer.
The description of using ice chips for a portable unit means one of two things - either the most effective water temp for heat transfer is close to freezing or it was the most efficient way to provide a heat sink was that rather than a heat pump or thermocouple. I suspect the latter given that you already have to have a water pump circulating the water.
The simplest arrangement I can think of requires throwing away portability. You'd need to have two buckets - one with mostly ice and some water in it and one with just water in it. The ice bucket sits at a somewhat higher level than the water bucket with a siphon tube leading down into the second bucket.
The second bucket is full of water and has a fully submersible aquarium heater in it that's pretty precise and fairly high powered - say 150 watts. It also has a submersible pump (power head) that has two outlets. The first just circulates water rapidly inside the bucket to maintain temperature uniformity. The other has a second tube attached that feeds back into the ice filled bucket.
Ideally, you want a second thermostat opening and closing a valve in this second tube. In reality, it's probably cheaper to use an adjustable clamp. This means the aquarium heater works harder when they are sitting there in the rest state and a lot slower when you're swishing your hands around in it.
Calibration in this case is a matter of lowering the thermostat on the aquarium heater bit by bit between sets until the recovery effect drops dramatically. Given that the environment is typically around 70 degrees, I'd say start at 65 degrees and go down from there.
