It's innovative because it works with your perception of temperature, rather than actually cooling your entire body (or the room).

I'm curious what thought the designers put towards altering your bodies perceived sensory information as I would have thought it would be somewhat dangerous especially in instances of perceived level of exertion due to physical activity where you may not realise you are overheating or more-so dehydrated than you feel.

 

Was thinking the same thing

Maybe this will fix throttling (passing out from a heatwave)
LOL

But basically what we do now to cool body is same as remove cpu and gpu coolers from case and install conditioner to cool down air inside case. So idea is right.

Well, I think the idea is to use it in normal office buildings and/or activities, and not survive the desert without breaking a sweat or overclock (excersise).

Truth is, there are $ billions wasted in cooling buildings excessively, with spoiled occupants beachin about temperature all of the time, and having AC running cold year long, even with outdoor temps close or below the comfort zone etc.

There are also ofc the lasy mechanical engineers, the cheap facilities, the stupid laws and the incompetent architects, sure.
Needless to say, that the vast majority labs in campuses and companies etc are over-cooled. You would be amazed on how many million square feet of "labs" and offices around the world have "specific" 68oF / 20oC thermostat requirements because of the above, while in reality everyone who is doing a "mission critical" task that requires specific temps (e.g. biology labs), actually is not relying on the AC to keep their experiments alive - they just use special equipment with very precise controls.

Setting your office's indoor thermostat @ mid 70s instead of 68~72oF would save insane amounts of money without any danger to our physiology.
Even high 70s would not really mean anything bad. Certen people are just spoiled / misinformed and have zero patience. Its a social think too ofc.

It you google what kind of energy consumption is needed to satisfy the cooling requirements in the US, you will see that that alone matches or surpasses the total consumption of larger in population countries with heavy industry.

too bad the economy and energy companies wouldn't allow this to go mainstream for another 50-100 years until they've made enough profit

so let me get this straight. MIT take bright peoples ideas, slap 10k in their hands and then what?

it almost seems like scheme are setup to funnel and take away positive ideas as you hardly ever see real world releases of this tech rolleyes.gif

^That's basically how it works. Idk if theres some clause that says any patentable ideas become property of the institution (as such happens when working for a company - generally speaking) or if they have the option to keep the idea for themselves and patent or sell it, but I'd like to think they are compensated generously if the former.

This will result in HEAVIER and BULKIER gear. that might that might actually trap heat. Heat needs to be expelled. Uniform doesn't help.

This is probably much cheaper, feel much better than a wrist watch.

Here’s how it works: Using a compressor, 99.9% water-free and oil-free air is transformed into 60-degrees of dryer, cooler air that is then pumped into the pads, circulating at 200 times a minute. It takes a minimum 30 seconds to revive a player


Maybe put these systems in humvees and tanks.
