You are lowering the bar.

When you started I immediately thought of "evapotranspiration." Authorities used to provide a weekly forecast in the Sacramento Valley to let farmers know how much they needed to irrigate their fields.

😅 the plant is blowing its self cool

What a useless product. Pay more and get spied on by a charger with a vape screen just so....what? The charger block isn't too warm? Like wtf is the point of the thing
@JohnDuthie Says:
The plant is sweating

Can we do Fahrenheit?
@matthiasj668 Says:
Enjoyable info about the way nature manages heat like an organic solar panel. The important thing to notice is that instead of absorbing radiation/light and converting it to 100% heat, it is evaporating, and so not convert 100% into heat, but just less.
Having that said, it does not have a link with an usb-charger with smart thermals. It was enjoyable to

Why not it contains water and when it sweat or Evaporate its Temprature will Drops very simple.

Convince my friend why most of a plant's weight is just air
@francine4773 Says:
I assumed it was something like that from the thermal scan, the pot is hot as well, the dirt is absorbing the heat, but the plant is absorbing the water from the dirt for its own processes. Which goes into..???
Oh
@adam.tclark Says:
Really neat point about plants! Basically little solar ovens that use solar power to pump water.
Just to grump a bit - I suspect the plant here is Hylotelephium (Sedum) spectabile, or something like that? If so, the species likely switches to CAM photosynthesis when under water stress (e.g. sitting in the sun in a small pot, unless it was recently watered) - meaning that the plant closes its stomata during the day, and leaves them open only over night (basically "holding its breath" over the day, running photosynthesis and respiration using stored CO2 and O2 to avoid water loss during the warmer times of the day).
This would mean that the cooler temperature indicated by the camera might be more linked to the spectral properties of the plant than evapotranspiration per se. Plants do everything they can to reflect IR, since it heats them up without having enough energy to drive photosynthesis. This keeps them cooler than lots of other surfaces - but also really confuses a lot of cheaper IR temperature sensors, since they reflect a weird mix of wavelengths that tend not to be found together for measurements of other materials (that's why a lot of IR temp sensors include different modes for different materials).
Not to say that the main message here is wrong! But for this specific plant under these specific circumstances, my guess is that the effect here is more a mix of real cooling via reflectance, and apparent cooling due to sensor limitations.

@Information_Seeker Says:
there's also materials that can cool themselves below the ambient air temperature without the use of evaporation, they're highly reflective but also highly emissive in the right wavelength to send their heat out of the earths atmosphere

Is it called transpiration?

So, plant trees to cool down
@Jon-t6c Says:
Yeah, it naturally and slowly moves a small amount of water...
People rarely point out that you also poured a bunch of water on it for it to evaporate.
That's where most of that energy to dissipate came from.
If you had poured water on the concrete it would have a similar effect.
And we salt roads when it's snows ...
But we don't water the roads when it's absolutely roasting hot and every little bit of water has gone and there no way to do evaporative cooling and the surface just starts to fry.
People who water their gardens adequately over time have lust thick forest like gardens, often no matter where they are or how hot it is....while gardens nearby who don't water might be complete dustbowls.
And any large concrete surface that hasn't any moisture is boiling

@DANGJOS Says:
Before finishing the video, as someone with a thermal camera, and one who loves this topic, the answer is 'evaporative cooling'. Plants lose water through openings in their leaves, and this can actually help them cool off. And if anything, plant leaves likely absorb significantly *more* sunlight than concrete does, but thanks to the heat of vaporization required to vaporize water in them, they can override that effect and stay cool. You could actually demonstrate this by throwing water on the concrete, and you would see the wet spot remains much cooler than the surroundings until the water evaporates
@daninosaurus Says:
You know, right from the start I thought "transpiration, huh, it's obvious", you mentioned the photosyntesis and I was like "nooo, I am sure you already knew but are downplaying your cleverness just for the sake of the video's script and contect, etc, etc..."... and then I thought about a recent annecdote where I felt silly because I didn't take into account the power of water transpiration to bring down the temperature of the surface it transpirates from, bear with me because, at least to me, it is quite a teaching example: I was in a place that was way hotter than it should be and was a bit angry at that place owners for not keeping the temperature within reasonable limits. Then it come to my mind that I had in by backpack, from work, a thermometer, but one with a probe that was designed for food and liquids, therefore, for air it would tell the temperature just fine only it would take it much longer to get to the right temperature and it would not fluctuate rapidly with rapid fluctuations of the air temperatures, but I brought it out anyway. When I took it out and turned it on it was showing, 25ºC (77F), and I knew that the air T was at least 30ºC (86F), so what did my dumbass brain thought instantly? add some saliva to it (liquid) so that it can transfer the heat from the environment faster to the probe and I started shaking it in the air.... what happened? the temperature started instantly dropping because the water in my saliva started evaporating from the probe taking with it heat from the probe having the same heat reducing effect sweat has on us... I felt stupid but it was a nice teaching, or knowledge settling experience hehe

“Okay, this may ultimately be an ad for a phone charger but HEAR ME OUT… we should totally plant trees in and around cities because it makes them cooler.”
I’m just poking a little fun because, honestly, this a nice little strategy.
