An insulated back pack (can be set next to the person) holds a storage of ice with a tiny water pump and battery, possibly aided by some solar cells. The pump sends water in cyclic motion to the neck area, worn like the Core Personal Body Cooler, or like the Coolware Personal Body Cooler. This cools
the blood in the arteries, and thus relieves the whole body. Two digital thermometers check and set the flow rate, so that the water reaching the neck, is only at a slightly lower temperature than the neck itself.
Price $44 in all supermarkets.

Can't a serious invention get any merit on this site? |
|
| |
But seriously, what about actually circulating the blood through a heat exchanger? Most people will never notice the two fang marks on your neck... |
|
| |
Hmmm - what's the difference between this, and any other personal blood coolers on the market, like fans, water-atomisers, water immersion systems (swimming pools, rivers, the sea, etc) - other than it can be worn on the body? |
|
| |
Wouldn't carrying a pump, battery, and/or ice supply on your back be ridiculously heavy and cumbersome? What is the problem with the existing devices (or, for that matter, a wet towel around your neck) that this is intended to address? |
|
| |
When the humidity level is up at near saturation (like in the wet tropics in summer)- a wet towel around the neck does very little in the way of cooling. |
|
| |
I live up here and I can tell you that in the "build up" to the wet season, when the humidity is very close to dew point and the temperature can at times be above 37 degrees (centigrade) - even body sweat simply becomes warm water on your skin, with little or no cooling effect. |
|
| |
Like [Grogster], I thought, or hoped, that this would be a device which more directly cooled your blood. This could be done either by re-routing an artery through a portable cooling pump, or by having a small cooling system instered subdermally - this could have cooling elements wrapped around an artery controlled and powered by an inductive loop mounted on the surface of the skin. |
|

[hippo] I was misled in the same way by the title. The
problem with that idea is that it's already done better by
skin). I'd like to see the blood routed to an external heat-
exchanger
through clear tubes: The advantage of that is the
[a]esthetics. I think jewelry at the sight of which some
people faint would have a big appeal. Cooler than blushing
and sweating, in a different sense of "cool." |
|
| |
I'd prefer a backpack full of boa constrictors on ice. Wrap one around your neck, and you have cold blood circulating next to warm blood. Ahhhhhh... |
|
| |
And as the torpid poikilotherm warms, and, finding itself
coiled around your neck begins to squeeze:
Ahhhhhh...eeeEEK. |
|
| |
And they will say of him, "...well, at least he was cool under pressure..." (sorry, couldn't help myself) |
|
| |
If you put a wet towel it is either too cool, or under humid conditions does not cool at all. |
|
| |
You don't want to let the skin do the job, because it smells. (Of course it would be stupid to to never let yourself sweat, just like its stupid to sit all day glaring at the PC, and pressing RUN after download, instead of running around the fantastic scenery where you live). |
|
| |
When you put a cold water bottle on your neck, it cools the whole body! No need for fangs.
The problem is, that a cold water bottle gives you a headache, same as eating ice cream too quickly. |
|
| |
So you need to control the amount of heat. |
|
| |
Wouldn't it be easier to wear a cold pack on your wrists, over
the ulnars/radials? |
