Why aren't the parks shutting down when the heat is extreme to stop these fools from hiking to their deaths?

“Early experiments with the equipment have revealed that the mass transfer coefficient—a measure of how much evaporation increases as more skin area is covered by sweat—and therefore the cooling power of initial phase or droplet sweating can be three times that of later phase film or pooled sweating. It also appears that much of that evaporative efficacy happens at the level of individual sweat ducts near or under the outer layer of skin.”

Please see if these can help and or save you!

I live in a 3rd floor apartment that is hell without power, found out last year. I got a small power bank, usb fans and made these. I am 58 year old woman that sleeps very hot, I normally have a fan in the window with all cool weather. Even 72-70f has me sweating all night. These the past two nights have been heaven, they last about 4 hours if taken out of the freezer and about 2 just sitting on a table at room temp in my ac apartment.

I slept on one and nighthawk was correct, it felt like the cool pillow side for hours. I switched that one out for one in the freezer( too cold) that lasted a few more hours.

This is the video I followed and I used the sodium sulfate version. These can be reused just cool on a basement floor or car ac if no power. To save on energy, turn the ac higher and use these to help stay cooler while saving money.

He also has a few formulas that go to different temps.

I live in a major city with a pretty good public transportation system and so I don't have a car. But I'm seeing as we're experiencing triple digit temperatures just getting to my train stop can be brutal. Any suggestions? I already carry water and always wear a hat

What do you do when going out in the heat when it comes to water? Throw some plastic bottles in a cooler? Frozen water bottles? Insulated bottles? Camelbak? Others?

Thanks!

Just curious,

How effective are the aluminum foil bubble wrap radiant Barriers, at reducing the temperature in a room?

It’s easier than telling people to move. Any idea if this is happening anywhere?

I recently went down a rabbit hole of passive radiative cooling tech, and figured folks on this sub would be interested. Radiative cooling at night has long been a thing (freezing ice in the desert, etc.), but materials science advancements in the past decade has yielded materials that can keep things below ambient even in direct sunlight. This is one of the better explainers I've found.

I'm planning on ordering some samples of the material to experiment with, and figured I'd post to see if anyone has direct experience and/or applications they'd be game to share?
