Cutting Ice With Diamond 

I thought the same (not fact checked/Google): Thermal conductivity of natural diamond was measured to be about 2,200 W/(m·K), which is five times more than silver, the most thermally conductive metal. The value for pure silver 406, for pure copper is 401, for nickel 91 and for stainless steels around 16.

​@@randgatethats actually really interesting, i would not have guessed that at all

That blade is carbon steel not stainless steel though, so it should be closer to 40W/mK

it would be in between those two

@@coin777 Yeah obviously, still I’d liked to actually see the diamond outperform the usual everyday top conductor - copper.

Whoa ho! Now that's thinking!

Minecraft moment

Genius!

Don't we all?

What's gonna heat the diamond scoop? If it doesn't snap.

It's in your thermal paste.

Blessed pfp

Same thought immediately imagine replacing heatsinks with diamonds. Would probably light up really cutely too

Idk about all thermal paste, but one I used to use from Microcenter was made of synthetic diamond because of its incredible heat transfer abilities, idk if they still make it anymore since MX-4 ended up blowing any other paste out of the water

I think the best you can do is graphene

i probably have like 5 grams of diamond next to me, it makes for a fantastic abrasive.

Lab made is nowhere near as expensive as the natural bullshit, one of the most common gemstones with the price of the least common lol, you have to be dumb to buy the natural kind if you just want to put a stone on a ring.

Synthetic diamonds are surprisingly cheap. The price of natural diamonds is entirely based on marketing and false scarcity.

@@adamfreed2291 yeah i know, tho synthetic diamonds for jewelry are a whole lot more expensive than abrasives, but still, 1/10th of the price of the naturals.

​@@adamfreed2291And human suffering!

I scrolled past then realized what i read and busted laughing had to come back and like 😂😂😂😂

like a warm diamond through ice

I'm using this 😂

I was about to say this 😂

Wait is this a reference. I am not getting it 😅

Stainless steel is much worse than steel. Most likely, you were stirring your tea with a stainless steel spoon. Try a copper or aluminum spoon.

@@ColCurtis My parents have some old silver spoons, with then stirring tee is getting your fingertips quite hot. But it is nothing compared to stirring tea with a heat pipe.

​@@ColCurtis steel in general is a poor conductor of heat, too much thermal mass, it doesnt like changing its temperature, but once you do get it hot, itll stay like that for a while

​@@karstenschuhmann8334 it's tough when there's no clean spoons and I all I have left to stir with is my heat pipes

Make steel razor 30 time thinner. 😊

Oxygen Not Included?

@@germankerman984 yep

I learnt that from Children of a Dead Earth

And that game was Oxygen Not Included?

Subnautica.

was just thinking that!

it's a great idea until you realize diamonds are flammable

@@KVJ1234 Yes... at like 2000c and with pure oxygen running over it... It isnt going to catch on fire from 70c I dont think...

unless your talking about like an industrial heat sync. I was thinking of like a pc heatsync.

Much lower tensile strength than copper though. Much less resistant to shocks and would develop cracks, so water-cooled / portable devices are probably not a good idea. But as the price of copper keeps going up, and the price of manufactured diamond keeps going down, who knows what the future holds.

Really? I was thinking of this idea for the last 20 years, but I did not know someone actually made it.

@@karstenschuhmann8334It’s pretty common if even Seen on TV pans use it. I assume most just don’t bother mentioning it as their pans actually work

@@DeathnoteBB Real diamond coatings are pretty expensive. I doubt in any of these pans diamonds actually contributed to its properties. ELAC had very expensive diamond speakers. They really had one speaker membrane made from diamond, but it was so small that it was only used from 17kHz to 200kHz. I doubt anyone could hear the difference. It was a speaker optimized for cats.

But the pan is still made of metal isn't it? Does the coating really do anything?

@@Elena-tj3so i guess it would spread out the heat better on the cooking surface, but i doubt the sear would be that much better.

And you can make a very small part and it'll take a long time to wear and it'll conduct heat almost as well as possible.

@@VeteranVandal The fact that hobbyists can 3D print diamond structures at will is proof that we're living in the sci-fi future I always dreamed of.

@@Drekromancer i dont think they are printing diamonds lol; the nozzles of 3d printer is made up of diamond

this is not the reason, It’s because diamond is extremely resistant to wear and abrasion

​@@michaelphone8739There's lots of options that are extremely resistant to abrasion though, the key is that diamond does both, and it does both of them really well

Hey carbon steel is the next best thing. You just need 98% more carbon to even it out.

Diamond combusts and doesn't conduct electricity very well. Besides being a very hard and prone to breaking material. So it's not a great wok material. Though it's used to line pans as a coat.

@@VeteranVandal The word you're looking for is brittle.

It would just burn and disintegrate. It's made basically a pure carbon. ,,, Like firewood

@@erebusaeon6945 Metallurgy/materials science joke, I love it.

The first thing I thought too. But even synthetic diamonds cost a lot.

Hypothetically yes but realistically no. For something like a heat sink for a computer there are so many other factors at play that affect the end result. Despite being very hard, diamond is quite a fragile material. It's just like glass, which is harder than common steel but not even close to the durability. This means diamond exchange fins would have to be thicker, limiting surface area relative to aluminum or copper fins in the same volume. Furthermore, we already have heat pipes, which have a far higher effective thermal conductivity than diamond does. The only place diamond makes sense to be used in computer cooling, it is already being used in. That's in thermal interface material, I.E. thermal paste.

Dream material for TIM, not useful for heat sinks.

Would be interresting in some spechal cases, but heatpipes are still more effective than diamonds. Diamonds are like 2300W/(m·K) while heatpipes have at least 10kW/(m·K)

​@@markjacobson4248 Heat pipes aside as they are combined with fins as far as I know, the fins of an aluminium (or copper) heat sink aren't usually thinner than what a diamond might be cut into (the diamond sheet shown in this video is 0.5mm, which is less than a lot of standard heat sink fins), so diamond, depending on type, being about 5-8 times more thermally conductive than copper should be able to conduct heat much more quickly while employing a similar form factor. Whether it is possible to combine them with heat pipes in a similar form factor is the question.

Diamond has the highest thermal conductivity of any common material, and a good chunk of the materials that beat it are also made of carbon

"Oh that's cool" funny REAL FUNNY

@@lander90 -real- _really_ funny

I don't have too much to back this up but insisting that synthetic diamonds are "fake" seems like mining and jewelry company propaganda to me

@@kie2 Not fake as in synthetic, fake as in cubic zirconia. Synthetic diamonds pass heat-related tests just as well as natural ones.

Thermal properties. Diamonds do not conduct electricity usually, unless they are doped. It has high thermal conductivity because they have very strong covalent bonds and low phonon scattering, so the vibrations travel more coherently than materials that have many crystalline defects.

“I always love seeing…” how often are you seeing this?!? Do you work in a cpu heatsink testing company?

@@_..-.._..-.._ oh no it's just one RU-vid video but I get it on my feed regularly and watch it every time

Spoken like a true scientist.

AND a comparison with a 9-volt battery attached to the diamond!

This guy knows what's important!

Diamond ice cream scoop.

It seems it needs to come to be a thing now

@@SianaGearz They already have an aluminum ice cream scoop. The ice cream scoop is called zeroll, it's about $20, but it's literally the best icescream scooper in the world. Fyi, only handwash it, do not put it in your dishwasher because it has a liquid in the handle that has an even better thermal conductivity and it will solidify and lose it's effectiviness due to the heat generated in the dishwasher, but you really only need to rinse it off between uses, so it's not even hard to clean.

I was thinking how carbon fiber or graphite compared to it, too.

​@@freshcoatpaintingmore9951graphite is spread out in comparison, with a flat geometry, where in a diamond the carbons are packed together in tetrahedrons

I mean, you could melt it and use a water jet

water with entrained cutting compound? which compound would you pick!

@@CothranMike CBN most probably, or just more diamond.

@@younscrafter7372 “I mean…” Gen Z detected.

​@@_..-.._..-.._people have been saying that for decades

Yeah I want one as a gift for friend who make cocktails.

look up "cvd diamond wafer"

@@MaratRostov thanks!

like a glove?

@@redwarf8118 I was thinking something with a known insulating ability, better than a glove

@@chrislarmourso oven mitts then?

I mean...technically heat IS a byproduct of pressure.

Eg, ice skating

The company I work for is working on just that, but for for GPUs (specifically with AI chips in mind). It's still a ways out and won't find it's way into consumer electronics for a while, but it's on it's way!

I’m definitely not particularly knowledgeable but I feel like that would be less useful than you might think. Overall heat conductivity would be limited by the slowest link in the chain so: * Electronics generating the heat wouldn’t necessarily pass heat to the spreader any faster * Similar to current heat spreader to heat sink connections, the imperfections in both surfaces would limit total conductivity i.e. needing thermal paste which will limit thermal conductivity * Not using thermal paste is still not an option as you just have insulating air pockets instead * At the end of the chain, you’re still trying to dissipate the heat to the low thermally conductive air so the heat capacity of the cooler would have more effect on the cooling capacity/ability of the cooler.

@@SkyChu0 if you slapped in diamond as a replacement to the copper we have now you'd be correct. You have to bond the diamond directly to the chips themselves, grinding away parts of the casing. The long term plan is to use the diamond as the substrate the transistors live on directly.

@@Dysiode sorry, my comment was more directed towards the original comment of the cpu heat spreader. My layman understanding towards your company's project at the moment can only see a reduction in heat clumping/hot spots rather than necessarily improved heat dissipation. Would the engineering be around combining the die and cooling solution into a "single" cohesive link? Are there engineering challenges around breakages due to the reduced malleability of diamond? Again, limited understanding of any of this so I just ask because I don't know.

Doesn't look like it, you'd be able to tell fs

​@@Anonym00Uthats why they said nearly

Yeah, and for the same reason. It's a great conductor of heat, so it feels cold when you touch it

Ice is also the nickname of my favorite substance and the acronym for the group that took my gam gam away

@LinusTechTips you know what you must do.

That's the first thing I thought of when he started the video!

A very good game where you need to understand the elements and physics interaction to survive. I find it very interesting that the only reason you can only survive mid-game is because you find a machine that do not follow the laws of conservation of energy... Very good demonstration of a system entropy. Just a small warning, you need a lot of time to play this game, and you need to be prepare to lose a lot 😅

I guess I didn't play it enough

​@@pierrotAgood ol AE-TN

Good game. I would rather it without the stupid animals, though.

Stanleymes in Dutch as well (mes translates to knife)

Frisbee and Hoover are other examples of the same phenomena

Actually if you look it up it appears to be an American brand. A quick search finds pictures of product packaging showing large made in America signs on them. Also now that I think about it, in the UK apparently they tend to call any vacuum cleaner a Hoover no matter the brand, but while we in America certainly know of the brand hoover, we don't do that here. So perhaps the fact that you can find Stanley knives here in America doesn't really change the situation. Still I recognize the term as meaning basically a box cutter.

or a diamond frying pan?

Do you mean a stove made out of diamond or a stove that uses diamonds as fuel?

completely diamond stove WITH DIAMOND FRYING PAN but diamond is not the fuel

​@@carmin.e From browsing the internet a bit: I guess diamond would be pretty nonstick, since it's a crystal. It won't get scratched because diamond is very hard, but it might shatter if you drop it. Being a good conductor of heat helps the pan heat up quickly. Since it's not ferromagnetic, it would need a ferromagnetic coating to work with an induction stove. Regarding specific heat capacity: At home, you want a pan that can store a lot of heat energy, because home stoves are uneven. Restaurants want pans that don't store too much so they can heat up quickly. Restaurants use aluminum which actually has a higher specific heat capacity, but can be made thinner. Home cooks use iron which has to be made thicker to store heat, but is cheaper. Diamond is about half as dense as iron, so a diamond pan would have to be twice as thick as a cast iron pan if you want to sear a steak at home, which would make it expensive. But if you're buying a diamond pan maybe you don't care about the price. If you're at a restaurant with a stove that can put out a lot of heat, or you don't need to store a lot of energy for what you're cooking at home, you can try to make a diamond pan with similar properties to an aluminum pan. It would have to be about 1.35 x thicker than an aluminum pan to store the same energy. But I think at that thickness it might be pretty brittle. Diamond has a low fracture toughness, because it's a crystal. You can get diamonds that aren't one piece of crystal, like the kind used for drill bits. I think you'd want to go with that, but the thermal conductivity might be lower, it's more porous so it might need a coating, and it's much less pretty. Diamond has a much lower autoignition temperature than iron or aluminum, but I think it's still high enough that there's not much risk of your pan catching on fire. I think ovens have some sort of insulation in addition to whatever metal they're made from, unless it's an old cast iron stove.

⁠@@carmin.eWhy would you want a diamond stove? You want the entire stove to be burning hot?

hold it with a heat sink material which you then handle with warm hands. You will want to provide the heat for your hand, hot hands brands comes to mind.

Yeah, my thought was a diamond heat pipe.
