Bay Area high school students win MIT grant for invention to cool down firefighters

[@GruneD]

Funny how most positive things like this don’t get any comments at all 😅

[@Mike__B]

That's because most comments are negative in nature. "Oh a news story where I can't blame (insert political party here) or (insert race here)... why do I care"

[@Mike__B]

Small bit of constructive criticism, and I am in no way trying to be negative, it looks to use water to move heat from the head to the backpack where a radiator will cool it down, basically like a computer's water cooler. The problem is the lowest temperature for the water to get will be ambient air temp, so it seems to work well in a classroom where the ambient temperature is somewhere around 70° however, if you have firefighters working in hot conditions due to fire or hot summer temps, that ambient temperature very well could be higher than the firefighter's skin temp, so this system would actually do the opposite of cooling. You would need have some mechanism to create a phase change for your fluid in order to dump excess heat and return a fluid cooler than ambient, think A/C unit or refrigerator. That however would require considerably more power though as you'd need a pump to compress the gas back into a fluid.

Yeah I thought the same. They need to explain it more. Are they doing something different or is it like how a PCs cooling system is set up?

Student at 0:14 here, we’re using thermoelectric pads to drop water temps to around 50 degrees to mitigate the risk of vasoconstriction and then using the fans to disperse the heat generated by the other side of the thermoelectric pad, so our water temps are much colder than the ambient air temp 😁

@@theinfamousg7945 Excellent then! You guys did a fantastic job on what little I could see in the video, and the fact it was even better than that... nice to see a young generation of thinkers and makers doing stuff. Great job, you and the whole group keep doing what you're doing.

Darpa/Rand corporation build something like this, except it was gloves that cooled or heated up. Designed for military use. From what I remember it worked pretty well

[@A3Kr0n]

Cool enough, but we already have cooling suits that even work on the Moon.

[@brosephbroman7564]

My first thought too. I was wondering why it hasn't been used for firefighters as well. 🤔

[@vineetdodd9915]

Amazing 😀

God bless those students ❤❤ ❤❤❤❤❤❤❤❤

My great uncle went from MIT to the DOD to a looney bin. Hopefully, none of these kids will get the MK Ultra treatment.

[@FlyBoyMT]

No wonder so many of your KZbin comments seem to warrant your own trip to the looney bin.

[@RacerX1971]

Nice

[@Dimaz42]

could the battery withstand the heat?

[@Terpy_Toine]

NICE ARDUINO PROJECT!!!!!!

[@ByGodsGrace99]

Tough!!

[@pepeshopping]

Nah. Weight? Batteries? Autonomy?

[@theinfamousg7945]

Weighs 9 pounds total, batteries were a struggle on our limited budget, but the only non-autonomous part of the device is the choice between heating and cooling
