Stanford Device Cools Body Inside Out
polished look 2 writes "This is a way cool invention: Those bright, eager scientists at Stanford invented a device that cools the body by drawing the blood to an extremity (such as the hand) and pulling the heat away it - thus the blood becomes cooler which is then re-circulated through the body. The net effect is that the entire body is cooled via this relativly small device."
You could take peoples excess heat and use it somehow... I suppose. People are great renewable energy sources. So you wear a suit that has a temp control of some kind in, it keeps you at a lovely temperature and you excess heat is siphoned off and used to power stuff. Might need a bit of extra infrastructure engineering though.
The device is external and cools the blood externally. This simply gets more blood to the surface by lowering the air pressure around your hand, then cooling the blood.
Neat, but not revolutionary.
Too many replies entered my head on this one:
- That's cool
- Do we get to pick the body part? I'm thinking: this and a bottle of Viagra.
- Imagine a Beowulf cluster of these?
- In Russia...
Ok, not that many...
this isn't a sig. i type this (including the two dashes), every time i post, just to make it look like a sig.
I ran competitively all through school, and all the smart runners knew the quickest way to cool down on a hot day is to put something cold on the inside of your wrists, and your neck... because there's a lot of blood flowing through there near the surface, and it "carries the cold" through the rest of your body and your muscles.
If you spend any amount of time in an ice bath, you can feel this effect, as well. Actually, it's rather unpleasant to feel the cold blood travelling back up your legs (but that's an extreme case).
I'll go RTFA now to check, but are they really talking about anything different?
As a side note -- for runners, it would seem to make sense to try cooling down the major arteries leading into the legs, but somehow I don't remember anyone pouring the ice or cold water into their groin.
So the diff is they use a gentle vacuum to draw the blood to the surface in the hand, only. Same concept, but with a little tech thrown in to make it work faster. Presumably there aren't any side-effects of tinkering with the blood-flow like that, like a permanent hickey over the entire hand.
Another side-note: apparently Stanford has already licensed the technology, "to AVAcore Technologies Inc., an Ann Arbor, Mich., firm that Grahn and Heller founded to develop the device for commercial application."
I wonder if they're planning on testing using some of the UMich sports teams here (I live in Ann Arbor)... Football especially is HUGE here -- the whole city practically shuts down on football Saturdays like today. The stadium has a greater capacity than the city population, and no parking, so as you can imagine it's chaos. I'm sure the Wolverines wouldn't mind the little boost during training that this might provide.
I called it beer. It's not only for drinking. You can also rest the glass against a vein in your arm to cool down the bloodstream quite effectively. One downside to this is that your beer gets warm faster, so you have to drink faster, but that in turn leads to drinking more, which cools down your body as well. This also has the positive side effect of getting you sloshed.
I don't recommend this cooler device for long distance driving.
Living here in the Sonoran Desert of Arizona where temperatures are 100+ degress for 5-6 months of the year, I can some practical uses for something like this:
- Athletic departments of colleges, high schools, etc; every summer, especially when football programs start up, students are taken to the hospital due to heat exhaustion and heat stroke
- Emergency Medical Response teams
- Anywhere where workers are required to be outdoors during the heat of the day
On average, 29 people a year die of heatstroke in Arizona alone. (That doesn't include the illegal immigration deaths, of which were 172 documented so far in 2004, probably more all told.) Something like this could be very useful, commercially, it just depends on how practical and expensive it would be.

Only difference is this time they're trying to cool people off, while before it was to keep them warm. Seriously, the previous idea was better (simpler concept, cheaper, etc) though it should be used to cool people off rather than keep them warm.
Those Stanford boys should read slashdot more often.
Couldn't this be used to warm people rather than cool them, by replacing the cooling part with a heating part?

Yeah wow great science. When I was a kid I had horrendous headaches. So when I couldn't sleep it off or had too many pills that weren't working I....
Laid on the couch with an arm hanging off the side a and wrapped my hand in a cloth that also held ice cubes. It worked. Or I would freeze a compress and lay it on my head.
So instead of a 'subatmospheric pressure environment' I used gravity. And instead of using a special water pumping coil I used, a washcloth and ice. Sure there was bit of a mess, but that was fixed by a mixing bowl.
Last time I listen to anyone who says I'm not good enough for Stanford
