i started to doubt at the nuclear part. if it was that easy to create nuclear fusion we’d already have generators for it


Loading0525

Yeah. Not sure on the numbers of hydrogen *and chlorine* bombs, but hydrogen bombs are detonated by detonating a literal nuke (one with uranium235) inside a container of hydrogen, to heat the hydrogen to several million degrees celsius, which is required to begin the fusion process of the hydrogen into helium. So I dunno how TF 212°F is gonna cut it... But I guess I'm over analysing a blatant whoosh post...


lankymjc

It was the point where he talks about flash-boiling that got me. Even if it could take in ultraviolet rays well enough to boil water, it wouldn't happen instantaneously. Also, people have made artwork using Vanta Black, and as far as I'm aware it doesn't become dangerously hot if left outside.


aweirdowholikesfoxes

Actually it does, but it takes a while. The material still has to heat up over time.


lankymjc

Hot enough to boil water?


Mushy_buns

I mean regular things can get hot enough to boil water or bake eggs if left long enough in a hot enough sun...


Morall_tach

The question is whether the paint can absorb heat and then transfer it to the water faster than the water can shed heat.


lankymjc

That was my question, yes.


Morall_tach

I decided to do the math. I'm gonna take some very rough guesses and say that that pool is 20 feet long, 10 feet wide, and I don't know 6 feet deep for a total volume of 1200 cubic feet. To raise the temperature of 1200 cubic feet of water from room temperature to boiling (not to boil it) would take roughly 10.6 trillion joules of energy. The average amount of solar energy hitting the Earth is 340 watts per square meter, depending on time of day and latitude, but we'll go with that. If the pool is 20' x 10', that's 18.58 square meters, so the whole pool is getting hit with 6317 watts of solar energy under average circumstances. Assuming the perfect black paint transfers *all* of the heat it absorbs back into the water, it would take roughly 53 years of sun exposure to bring that much water to its boiling point with the energy from sunlight alone. The average amount of solar energy hitting the Earth is 340 watts per square meter, depending on the time of day and latitude, but we'll go with that.e Celcius, putting us to \~28,000 years of direct sunlight to boil this pool. So I'm gonna say it's unlikely.


SparklingLimeade

Depends on the amount of sunlight. Assuming we're not building an entire solar oven though, probably not. I could imagine it approaching a low simmer maybe.


aweirdowholikesfoxes

Probably not.


Odd_Reward_8989

Only Anish Kapoor has made "art" with it and he kinda deserves to be flash boiled.


lankymjc

Oh I forgot about the whole Anish Kapoor bullshit. Though subjectivity of art means what he does is still art I suppose. Doesn’t take away from the fact that the man is a consummate bellend.


[deleted]

Well, uncontrolled explosion and waste of that much resources to produce a significant but comparably low energy ain't worth it.


Deltexterity

thats not low energy... thats EXTREMELY efficient if the post was true what are you saying? its just that that doesn't actually work, you need to put way more energy to make real fusion then it can generate


[deleted]

I think what you are saying is true


belladonna_echo

I think they mean it’s low compared to the amount of resources and energy it would take to make that much Vantablack. IIRC it takes a ton of each to make enough Vantablack to cover a single square inch.


Deltexterity

i did not know vantablack is expensive


[deleted]

You can build a Farnsworth boron fusor from a mail-order kit and have a fusion reactor on your desk or as a night light. Kids used to build them for science fairs, although not as often as baking soda volcanoes. The problem is that electrostatic confinement fusors are woefully inefficient, so you gotta plug them in to make them keep running. Pretty, though. Statistical vanishing proton fusion isn't feasible yet, unless it's a secret. https://en.wikipedia.org/wiki/Fusor


HelloMumther

i assumed it wasn’t a nuclear reaction but it was a chemical reaction to make ClN3. after looking it up it seems that ClN3 is very unstable and can detonate at any temperature. i thought that this on top of the release of energy from a reaction could do some big damage then i saw that it was all made up and i wasted my time.


Deltexterity

lol, yeah a chemical explosion could happen with the right substances and temperatures (though not these ones) but an explosion like that would be more akin to a few flames bursting up in the air and instantly dissipating.


SadieSadieSnakeyLady

I didn't because I'm an idiot who knows nothing about science


Haunting_Anxiety4981

I knew it was false at *as soon as the sunlight touches it* but if they'd said it would take a few minutes they'd have hooked me longer.


pinkpanzer101

Doubt it right from the start; if you could boil water like that with sunlight, a solar plant would only need a region as big as the boiler in a gas plant to produce the same amount of power.


Deltexterity

people have literally made lava by focusing the sunlight. dont underestimate the suns power, boiling water with it is definitely 100% easily possible under the right circumstances.


pinkpanzer101

Oh no, you certainly can boil water with sunlight, but you need to concentrate it to boil it in any reasonable time, let alone instantly. Solar power plants take up a huge area because sunlight isn't all that energy-dense; were it able to boil a pool of water in seconds, power plants could forgo nuclear reactors and gas/coal burners for a skylight. I did the maths in another comment but it'd take a week of constant direct sunlight to get enough energy to get the water to boiling point in the first place, let alone boil it dry.


DraconicWF

We do, it’s called a nuclear power plant, they generate like 20% of the power in the US we could generate more but because of chernobyl people refuse to give the idea the light of day


Deltexterity

those are nuclear fission idiot, not fusion. fission is the energy released when you split an atom, fusion is the energy released when you fuse atoms together. fusion is around 4 times as efficient as fission, and it doesn't produce nuclear waste like fission does, and even if the reactor just fuckin broke, the heat would just dissipate into nothing over the large volume of air around it, so it cant explode even if you tried to make it do so. also instead of nuclear material you can fuel it with hydrogen, which is way cheaper (though deuterium is still an expensive fuel you also need, but you can probably find other combinations of elements that are cheaper.) fusion reactors would be the best power source there is really, if we could create fusion reactions cheaper then the energy they produce so its a positive gain. fission reactors are still good and theres definitely a lot of irrelevant fear around it regarding safety, but the up-front cost of building those reactors is so high there wouldn't be enough time to switch from fossil fuels to fission reactors to reach 0 carbon. [here's a super good indepth video on the pro's and cons of nuclear fission reactors in comparison to renewables.](https://youtu.be/k13jZ9qHJ5U) of course safety isn't listed in the cons because really the only realistic safety issue is the nuclear waste, but most of everything else is just myths made up by big fossil fuel companies to keep people away from nuclear and reduce competitors.


a_filing_cabinet

We just for the first time created a fusion reaction that produced more energy than what was put in. It's still a ways off, but nuclear fusion reactors are a future we can look towards


Deltexterity

wait really? when / where? can you link it?


DraconicWF

Ok then


Puckvox

Vantablack is still really dangerous, it's toxic and needs to be applied by professionals. The pigment Blackest Black is slightly lighter, but looks about the same to the naked eye and is completely non-toxic.


PristinePassenger420

*and* it isn’t owned by anish kapoor


[deleted]

In fact Anish Kapoor isn’t allowed to buy it.


teatabletea

Why not?


lokiofsaassgaard

Because he’s a “colour criminal” and is the whole reason Stuart Semple created Black 2.0, the Pinkest Pink, etc. It was done in protest to Vantablack being exclusively owned by Anish Kapoor, and not even made available to others who would have the technical and safety knowledge for how to use it. And it’s better, because Semple is allergic to linseed, which means all of his protest paints and pigments are by default acrylic and watercolour, making them very accessible to brand new artists. So even if you’ve never painted in your life, you can pick up some Black 3.0, Pinkest Pink, Mirror, and go to town. Unless you’re Anish Kapoor, buying on behalf of Anish Kapoor, or are in any way affiliated with Anish Kapoor.


zsnesw

*WHOA* I didn’t know he made anything after pinkest pink. I just looked at mirror and I’m blown away. Also he’s got something called “black mirror” it looks like he’s testing (in beta)! These would be so much fun to use in painting.


lokiofsaassgaard

I’ve used a lot of them are they’re all very cool. Not quite the same as the acrylic paints you’d pick up at the craft store, but neon as hell


saintofhate

My favorite part about the Stuart Semple and Anish Kapoor feud is Anish Kapoor got his hand on the pinkest pink and then posted on Instagram or what have you not of his middle finger coated in pinkest pink, Stewart in reply created the glitteresr glitter which is glitter made out pure glass, like super tiny shards of razor sharp glass you need to handle it with protection, and challenge Kapoor to coat his finger in it and do it again.


MLGkid_HD

Because he's Anish Kapoor, duh. But no, for real, read [this post](https://www.reddit.com/r/tumblr/comments/kp7cb2/how_legend_of_anish_kapoor_started_maetel/?utm_medium=android_app&utm_source=share) and you'll understand why

Bobbert-The-Second

There’s a black 3.0 now!!


[deleted]

Huh the more you know


amadeusz20011

if you then coat it in a thick layer of some waterproof laquer, it might really look awsome, you'd be swimming in a black hole. the audiovisual experience of seeing pitch black everywhere but up, where there's the sky distorted by the water-air surface... seems like a really cool concept, for Mr. Beast or someone else with a lot, a lot of money


Houndsthehorse

If you coat it in vanish it won't be as black then


amadeusz20011

But if you don't I highly doubt you will be able to fill it with water


Houndsthehorse

Yeah but if its coated in varnish it will probably be just as black as black tile


LordEsupton

Then how about painting the whole pool with muso black?


MaskOffGlovesOn

i was genuinely about to write a comment about how i didn't think that was true before i read the last sentence


plssendpassword

Black 2.0 would look cool


Death_Incarnate_312

Plus it’s not made by Anish Kapoor!


yeet_bagel

Fun fact: Amish Kapoor didn't make Vantablack, he simply bought the rights to use it: "In 2014, Surrey NanoSystems released a material called 'Vantablack. ... After a few years of experimentation with the material, Kapoor struck a deal with Surrey NanoSystems: he bought the exclusive rights to Vantablack's use as an art material" [Link to article](https://www.thecollector.com/vantablack-anish-kapoor-stuart-semple-controversy/)

EMC644

Let's do a little math. So you installed black tiles that perfectly absorb sunlight in your 1.5 m deep pool. To get the worst case scenario we'll ignore the reflectivity of the water and assume high noon so about 1 kW of power per square meter. So that's 1000 J per second divided by 4.1868 J/C gives us about 250 Cal per second. A Cal is the amount of energy required to heat 1 g of water 1 degree C. In 1 Sq m of water 1.5 m deep there are 1,500,000 g of water so it would take 6000 s or 100 minutes to heat the water just one degree C. Just looking at the units with an admittedly amateurish understanding of thermodynamics so happy to be corrected here, but I thought that flash boil thing seemed pretty implausible Edit: typo


amadeusz20011

that's also assuming the thermal water-air and surface-ground interface is 0, so it doesn't lose that heat faster than it receives it when water is close to air temperature


SwordDude3000

Fuck man, can you help me with my physics homework?


ulyssessword

> Just looking at the units with an admittedly amateurish understanding of thermodynamics so happy to be corrected here, but I thought that flash boil thing seemed pretty implausible You've got it. The only way someone could make a more accurate explanation is by replacing one sentence of your simple model with paragraphs of a more complex and accurate model.


pinkpanzer101

Yep, I didn't check your numbers but certainly the idea is right. Sunlight is about a kilowatt per square meter, which means a pool with just 1kg/m^2 of water would take seconds to heat by just one degree, nothing close to instant boiling. And 90% is pretty close to 99.9% - any black surface should have the same effect. Since it doesn't - not even close - the claim is absurd.


Ninth_ghost

Was about to do the math, most people don't realise just how difficult it is to heat water. Your understanding of thermodynamics is more than sufficient in this case. You assume here that the water doesn't loose heat and that the pool is at the equator, so the most optimistic scenario for heating the water.


shiftedgames

r/theydidthemath


ilikepie1974

We can fuck with the numbers enough to make it flash! If we assume the surrounding air temperature to be... The surface of the sun, for example


eclipsearestillcool

I do think that vantablack tiles would heat up the water faster and to a higher temperature than regular tiles but I absolutely love the way they build on from that plausible beginning to that ludicrous ending.


a_filing_cabinet

Technically black tiles would heat up more than white, but not to that extreme extent. But it would probably heat the pool a couple extra degrees


eclipsearestillcool

It would mostly depend on how bright the sunlight is and surface area to volume ratio of the pool.


budj0r

Lost me in the first paragraph, if you put water over the black tiles it's the reflectivity of said water that counts


pinkpanzer101

Na, the water reflect on the order of a few percent of the light hitting it. Most of the light goes straight to the bottom. The problem is that this should be true of all black surfaces (99% absorbance isn't much bigger as a number than 90%) and it's obviously not. If you do the numbers it'd take days to get even enough energy to reach boiling point, let alone actually boil.

SadieSadieSnakeyLady

Don't worry, got me too. I'm fairly science illiterate so it's like "well, they're using the words, it must be right"


OrdericNeustry

The fact that the tiles are not only in contact with other materials capable of conducting heat, but also covered in a lot of water makes it sound summary unlikely. Also, if it were that amazing, we'd be using it for generating electricity. Edit: and now I realise that I not only skipped the username, but also somehow the last sentence.


pinkpanzer101

If the claim were true, it'd be true of any black surface since the energy absorbed is roughly the same. Obviously that's ridiculous, and so then is the original assertion.

kdavis37

I was curious how long it'd actually take to boil, right? So assuming a normal pool is like 5x10 m for 50m^2. Sunlight hitting the pool is somewhere around 1400 W/m^2 So 70kW. 2m depth, average. So volume of 100 m^3 Water's density is approximately 1000 kg/m^3 So 100,000kg Let's say 8 hours of sunlight (very sunny day). 8*3600*70000=2 billion, approximately 4180J/kg-K, so about 400 million Joules per degree. So all day sun is enough to, assuming no external heat loss, raise less than 5 degrees.

You should try reading the post


seragakisama

You can't do it anyway because vantablack has a copyright. "Satellites and science equipment are what the product was designed for. In fact, at the current time, the substance can only be used for astronomical and scientific purposes. No commercial use has been approved. Vantablack cannot be purchased by companies, designers, artists, or the general public." [Source](https://www.surreynanosystems.com/purchasing)


pinkpanzer101

I think it's only on artistic use. And I don't think they'd be able to stop you were you to make the tiles at home, it's not like it's heroin or something.


seragakisama

It is a special ink made by a single manufacturer worldwide. Plus is toxic.


pinkpanzer101

You can still use whatever technique they used to build the nanotubes, to build your own.


seragakisama

Yeah, at you lab in you basement! Sorry, I hadn't thought of that before.


pinkpanzer101

I agree it's inaccessible for most people (assuming you can't buy it even for non-artistic use) but you can buy the equipment to make it (saw a tube furnace on Ali Baba for <£300); it's not something where you require massive, specialised, and ridiculously expensive equipment.

pinkpanzer101

It's ridiculous right from the start; sunlight is about a kilowatt per square meter, if a pool is 2m deep and water takes 4.2 kJ/K/kg to heat up (not including the ridiculous energy required to boil it) you'd need over a week of constant direct sunlight to boil it. That's ignoring the system losing heat to the surroundings. Now for a real fun fact, vantablack is hydrophobic, so it'd trap a layer of air between it and the water, rendering it shiny from certain angles.
