Really excellent job! Great to see this method with the microspheres taken to what I think is probably its full potential, and in a way that's totally doable outside of a lab. It's also very impressive to achieve sub ambient temps without any sort of film or insulation. It must be radiating a fair amount of w/m^2 to overcome the breeze blowing over it. Very well done, and it was especially useful to include info about bulk suppliers. I'm still working on new methods myself. I'll be thrilled if I can hit similar numbers as you have.
Thanks. I appreciate the comment and for your earlier video that got us started down this path. Good luck!
@@TechIngredients So how about the polar opposite now, a paint that absorbs as much heat radiation as possible. Could be interesting for a purely convection based heat pump. Would be slow, but cheap to run 😉
@@DerSolinski that's exactly what I was thinking. Then I could have two separate roof panels to climate control my chicken coop year round with no power.
@@DerSolinski You're mentioning two different methods of heat transfer here. If you're absorbing solar radiation you want a solar heater (I think they already did a video on that). If you're looking for an air cooled convection based system you have a different heat transfer coefficient related to how efficient the surface of a radiator is at exchanging heat with moving air. It's a different problem, but still interesting.
Muso black would probably adsorb the most heat but it’s cost prohibitive. I’d try black 3.0 as a starter.
Just pre-emptively expressing here: Please do not change the format of your channel. It is perfect the way it is. It's so nice to listen to you without background music and overcommercialization or overproduction. You can see this creeping in old Mythbusters episodes and by the end of 8 seasons, the show was unrecognizeable. Tech Ingredients cannot be perfected anymore, it is epitome of high quality, small business vibe production. Thank you for everything you do.
Agreed.
Good call. The format is bang on. I also appreciate how accessible they make most things. For example explaining an affordable solution to make a mixer into a heated mixer. Even though he had the relevant equipment and you can purchase the equipment from the same place as the parts he suggested as an alternative, affordable solution. If only my teachers were half as good as what Tech Ingredients produces. A prime example of best use of social media and what it can offer.
Hear, hear!
Just need to sort out these audio hickups
I wholeheartedly agree with this comment. As an aside, I felt that the B roll footage when they left their home workshop to go to the warehouse was rather funny. I don't seem to remember them using b roll like that before.
This was always the dream of the web: to freely share ideas, innovate, and communicate. I have so much respect for the quality of your content, the production quality, the writing, the delivery, it's all fantastic, but the part that really blows me away is the commitment to getting the information out to the world, without putting it behind a pay wall or patent. You are truly working to improve the world, not just your own experience in it.
Wow, thank you!
I absolutely concur! it's natural selection
Well said, nothing to add.
This is rare on KZhead to come to this point of measurable and traceable developments with absolutely no other motive than sharing it with everyone. This is so inspiring and gives me hope in humanity. A few more of these guys and we d make so many more discoveries. Sure some researchers probably did this and published it, but this guy here brings it to the masses. Love this channel, pure gold
OP very well said and expressed eloquently.. Unlike my redundant statement here hahaha
I love living in the modern age. So much information is so freely given by people who I would NEVER have the luxury of meeting in real life, let alone enough time for them to teach me all of the amazing information they have in their heads. The only way to learn about stuff like this in such an in-depth way would be spending thousands of dollars going to college. I tip my hat to you sir, and your amazing knowledge. Thanks for sharing everything so freely, yet in a way thats so easy to understand.
Yes, we're so blessed to have these educational resources.
What i really love about this channel is that it is not just cool science on this channel, but it is a practical DIY kind of science.
There's only two kinds of sciences which are fun: applied and theoretical - everything in-between sits out of context of anything that seems relevant and therefore will bore the shit out of you.
So in other words... technology?
@@ObservingLibertarian Ok, but that's not really what they're commenting on. Not all applied science has a meaningful DIY component, which is a large basis of this channel's content. That's what OP is talking about, not whether there's anything beyond applied or theoretical science.
I can't express how much I love this. As a fellow engineer interested in thermal science I love this
Can we appreciate this guy trying to both teach and show us how to solve real problems at home? Keep it up! Definitely watching more content from you and subbed!
Thank you!
@@TechIngredientsany luck with a powder coating formulation?
Had to say, watching this for the second time, this is utterly amazing. I'm often critical and a bit of a 'know it all', as many of us blokes are. This is, from beginning to end, pure poetry for an engineer. The amount of thought and hard work is only part of it. The creativity and communication is too. The production and quality is first class. For some reason this viewing just blew me away and my mind has been flying on overtime with all sorts of ideas since. Someone who puts brains into this mode has to be just wonderful.
I had my shed painted with one of those products in Australia and before in the summer you couldn’t work in that shed and now it’s cooler in the shed than outside I was hugely impressed and highly recommend it.
could you tell us more about the product you used
Google Resene Coolcolour paint. Note the spelling.
What if this was used as the background for a solar panel? Could it help improve efficiency and reduce temperature?
Roof and sides? If roof too, what is the roof made of?
Hi Deon, what paint did you use mate?
I love how he explains every little detail of this process, even painting the surface, like a scientist, really refreshing!
Not only are you about the most intelligent human being I've ever seen, you're also extremely fun!! Your sons have no idea how lucky they are to have a Dad that can teach them all about science, and then go apply it in an extremely entertaining manner. I can just about see you saying, "hold my cold filtered draft malt beverage!"
I really like this guy. He's freaking hardcore! Tells you where to source the stuff. Make your own world's shiniest paint. Drills down into the details of why he's doing each particular step. I especially liked that part, that information is useful for whenever I paint anything not just this thing. Consider this shared.
Not only that, but his subtle jokes are quite funny and unexpected from a guy that looks so prude. Easily the greatest channel on KZhead.
@@TheAlbrowniv There are many contenders for greatest KZhead channel, and this one certainly would be in the top bunch for science related.. Also a big, BIG point in his favour, this guy is straight, and honest with integrity. You get NO payments from the big boys to promote anything here! He shares knowledge. More than that he shares his own discoveries. A great thing. Really a great thing.
I absolutely love the mildly comedic flavor of this episode. Science focused channels have a tendency to be a bit “robotic”, but your personality is one of a kind. Thank you for all of the amazing videos!
I completely disagree. I found the comedic elements are off-putting. They don't fit with the genre of the video. By its nature, the comedic content has to be somewhat fictionalized, and so its inclusion in what is otherwise a truthful instructional video makes it hard to take the rest of the video seriously.
@@rorypenstock1763 Different strokes I suppose. I love science and I love to laugh, so this was perfect for me.
@@rorypenstock1763 They kept the comedic parts limited to "how do we make watching paint dry interesting?" so it really doesn't detract from the episode at all. Adding balls jokes made it memorable. Completely disagree with you disagreeing Rory.
yes sir ....your content was always perfect and very understandeble. Now even better because you and your sons mix in a little bit more humor every day. You are one of the very few "serious" science channels on youtube that figed this out , just like Sabine Hossenfelder. It used to be old knowledge that people , if they are not already a specialist in the field your speech or demo is gonna be about....can only give you full attention for 15 minutes. Then you need a gentle reset with some humor and/or acting. You are doing that perfect.
Same here, almost closed the video at drinking propagation, saddly @Tech Ingredients do not appreciate the viewers time any more
Impressive! The whole process can be fairly easy to fit into a production line. My only concern is - how well this "super coating" can survive in real world conditions, like rain, snow, wind etc.?
This was fascinating. You never cease to amaze me man. You're the Carl Sagan of How To's in science and engineering!
Love the sublime comedic homage to Walter White (with all the sniffing and masks). Humour apart, the wealth of knowledge, imparted practical scientific approach, to "hot" issues in our societies, while maintaining a simplistic common-person narrative, is quite an astounding feat. A loyal subscriber, always looking forward to your episodes.
Many people have asked what _Breaking Bad_ would be like in a country with national health insurance. Fairly confident this is it.
I'm glad you didn't say free "Health Care". Nothing is free
He could have started to remove his pants, I might have fell out of my chair.
@@bertilhatt Oh sounds great. Walt weak and sick from chemo instead of recovering immunologically through spontaneous remission while his wife cheats on him with her boss. Except with the purchasing power of the Canadian dollar, Walt's family would have a far lower standard of living.
I just finished binge watching that whole series. My library has all of them! So awesome and free.
In Aerospace, when we solvent clean aluminum, the technique is to wipe the solvent on with a fully saturated cloth, wetting the entire surface, and then wipe it off with a clean cloth before it can evaporate. Then repeat as necessary. That prevents the oils and dirt from redepositing as the solvent evaporates.
You guys have perfected the art of mixing professional quality with a fun laid-back attitude. Love the little jokes with the big bag of powder and the brews. This might be my favorite upload of yours. Another great production, I would love to get together with my dad and do experiments and projects like you guys
Right *sniff!* I recognize Barium Sulfate when I see it... *Sniff!*
A bag like that in the back seat of your car would make a cop instantly forget about giving you a speeding ticket. Downside is that you might have to wait in jail for a while until they test it.
@@snaplash ...and if an Annie Dookan type (Google her) or other corrupt cop "tested" it (or just decided to replace it with his own bag), you might go to jail for a decade and have your car and house stolen and your life ruined...all because the government has a holy war (begun using openly-racist language, BTW) on "safer-than-alcohol" recreational drugs.
Just found your channel and im really enjoying it! So informative , and well spoken in a way that makes complex stuff easy to comprehend.
That tiny correction underlines how the doctor effortlessly expresses a huge amount of highly technical detail. Your communication skills are truely impressive, Doctor. I'm a big fan.
This is an absolute classic Tech Ingredients episode, I have heard about this super paint but had no idea it was this easy and inexpensive to make. Great video.
I think "easy" is a relative term here, but definitely doable outside of a factory, which is awesome. I'm personally not a fan of some of those solvents in workshop, but that's easy enough to work around, create a temporary solvent and paint drying booth with exhaust fans. What this should REALLY tell you, is, that at less than $5000 per ton for the raw materials and what we now know is required to manufacture it, there is zero excuse for this product to be sold at insane prices, especially given that the raw materials to make garden variety house paint are just slightly less than 1/2 the cost (titanium white for example is about $2000 per ton). The major downside is that even if this stuff hit commercial price parity with something like exterior paint, you're going to need 10 times as much of this product to cover a home for example (my last exterior painting required 22 gallons for 2 coats sprayed).
@@racerex340 When I say easy I mean comparatively easy. It isn't something that requires millions in investment to set up making it on a commercial scale and to make small batches at home is very inexpensive. You wouldn't really use it to paint a whole house, maybe use it as a coating for a heat exchanger or something like that.
@@schrodingerscat1863 I know, I was just being a dork about it. I could see a value in painting roof surfaces in extremely sunny places. Imagine the roofs of all of the buildings in Disney parks coated in such a material, how much energy could they save by dumping even just a percentage of the heat, or the roof of a surface in desert areas that experience a ton of solar heating? I'm also sure that with some additional research and development, products could be created and applications methods refined enough to require far fewer applications to hit the appropriate thickness level required.
My grandparents retired to AZ border in the mid-70's, to a totally planned community. The one thing I ever heard negative was having to seal the place up in June and leave the country to spend a few months on a beach, b/c it was so much cheaper than the developer's rustic "look and feel" flavoring sprinkled all over the place. I had a blue-ribbon chemist in my Dad's family also, and we knew about this tech. We laughed. That was the last of the post-WWII do-whatever-you-want, shoot-the-moon era. Now we have no choice but to be clever, and it looks like an improvement!
@@racerex340 When we crunch all the numbers and look at money spent versus money saved, the most economical option for general use is still just to coat with a regular white paint and insulate very well. Because those few degrees of sub-ambient cooling will benefit the building the most if the bulding is not insulated at all. Any insulation will limit what that sub-cooling can do for the conditioned space. But if we leave the building uninsulated, we waste a lot of energy. Plus, there will only be subcooling when that surface is kept absolutely immaculate. Which would require tons of regular maintenance. Which costs lots of money and resources. Any speck of dust or dirt or leaves or cobwebs will greatly diminish its ability to reflect sunlight so efficiently. And then the insulation will be the most important factor once again. So yes, I am excited about this information, but we do need to be realistic about its practical application in the short term, until more streamlined ways are created to maximize its benefits. I can see this kind of surface being very useful for applications where the added bulk or weight of normal insulation would be less desireable, and keeping it super clean wouldn't be too much of a concern.
I love how the results are cutting-edge and yet the explanation and showcase of the production is so clear-cut that I actually feel like I have learned a lot about this subject despite having relatively no experience prior. That's incredibly hard to do as an expert in any field. Well done!
he's amazing.
seriously this is so well explained in this video
I really hope this would cut cooling emissions in the world
teachers should be required to study his videos to learn how to teach :P
Your explanation of aggregate density optimization using nano particles of various sizes is truly excellent. Ted
This is really amazing. I wouldn't have believed it possible tbh without seeing it with my own eyes. Great job!
I'm wrapping my brain around this. A surface being heated by the sun is COOLER than the ambient temperature. This is one of the closest things to magic I've ever witnessed. Wow!
Check out our last video where I explained how this is possible.
I’m a Professional Engineer and actually thought this was an April fools joke. Amazing simply amazing.
Think of it this way instead: if the surface wasn't heated by the sun at all, it's backside would be even colder. Think of it more as it being highly resistant to sunlight, thus keeping things still relatively (still hotter than it would be without the sun, but still quite cool), than an actual "cooling effect because of the power of the sun itself".
How stable to rain and uv is this material?
It's Clarke's Third Law.
Brilliant way to make use of educational content and inserting some comedy. I remember hearing about some study or fact that students need a short break every 30-40mins during lectures/classes, because without that short break the mind starts to drift and stop paying attention. With that in mind, the short comedic skit you did was at the perfect moment. It immediately got me to laugh and then pay more attention. Bravo!
🙂
23:34 Priceless reaction. 😄
Smarter Every Day could just mosey by...
Love that I happened to catch this as the first episode I've seen. Thank you for an excellent presentation of just the type of science I'd like to apply to the painting of my home in the desert southwest.
Just recently I found this channel in KZhead and I find it very interesting and informative. Keep up the great work!
As someone who painted cars professionally, I always made a swatch (usually sheet metal because that's what cars are made of )and prepped/painted it at the same time and in the same manner as the vehicle I was painting. I would then use that to test whether or not the paint on the vehicle itself was ready for another coat or the next process and wouldn't have to touch the vehicle. I would also keep these swatches, in addition to photos of the vehicle in what was my portfolio.
You're making materials engineering cool andinteresting. Not an easy feat, and you do it without most of us even noticing! Great job 👏
Scaince
I've never subbed to any channel before, and I've been around for decades(!). This goes to show how much I *love* the topics your projects cover. And how much I *love* the way you explain them. Furthermore, that comic relief through the coating phase officially makes you a national treasure of a man, for me.
You are my hero. These are the most informative and detailed videos on the internet. Your style is perfect. God bless you and your family.
This is the kind of content that can actually change the world for the better. Thank you. I love this channel so much.
Wow, thank you!
@@TechIngredients you're doing a great job. Please keep this up.
I agree, great work!
@@TechIngredients What about the drivel spewed by Al gore and the 600 000 hiroshima bombs going off EVERY SINGLE DAY. He blatantly omitted the fact that its reversed at night. Could you please tell me what is fact or fiction snake oil salesman Al gore
@@TechIngredients Really love what you guys are doing and how the channel tries to find ways for the betterment of the world. This may open up a can of worms, but possibly the channel could take in outside suggestions for those people with possible world changing Ideas, but dont have the resources to build/test. Im sure many of us that watch the channel have a few ideas stirring because I sure do!
I feel you are one of the few people that could make watching paint dry entertaining on a video!
I mean.... he literally did in this video.
This was a good one. Thanks for the time and effort you have taken to explain the process. Thanks! 👍
this is yet another amazing AND useful project! I can envision a ton of applications for this stuff. Thank you for this!
“It's not bad... Even comes in strawberry." 🤣 I love the subtle humor that you bring to this highly educational content. Don't change a thing, it's perfect! 👍🏻
White powder at 17:50 reminded me of Walter White - breaking bad!
15 years ago I suggested to a co-worker at Invisalign that materials sciences still had several decades of achievements and was still the biggest area of innovation available to humanity. This video was a great example of how we still have a ways to go in getting to real solutions to practical problems.
I'm always impressed when I stop by your channel. Makes me wish I had time to do explore like you
II love the way you did this video ! You managed to produce a highly technical educational and instructional video in a manner this old broad completely comprehends. Your wit and humor cracks me up and led to a very entertaining lesson as well. Great Job!
Great vid. One small correction: while often used together with surfactants for better penetration, EDTA itself is not a surfactant, but a chelating agent ( from Greek χηλή, chēlē, meaning "claw"). Its molecules surround the barium (and other metals) ions to form a complex, much like holding a tennis ball in your hand. I reckon this inaccessibility limits crystal growth, making them smaller, but I don't have a source on this, just makes chemical sense.
Thanks, I was making this same correction.
All thumbs are fingers but not all fingers are thumbs. I present this to you as EDTA does act as a surfactant. A surfactant's job is to surround bits of stuff with a micelle. This allows for betters dispersion of the "dirt" or whatever you're trying to homogenize or remove better. EDTA is creating a sort of micelle by wrapping around the "dirt" in this scenario which is oxidized aluminum and such. It acts as the "claw" you are referring to. Wraps around and segregates the particle away from interacting with others putting it in a suspension. It is acting in the same exact way in this scenario so the use of surfactant is completely logical in this instance. You can argue semantics but that has no place among those just trying to relay something in a way you can understand. Edit: Dispersion does not require a micelle to be clear, you can do it with a myriad of techniques. The micelle example is the simplest to understand as you just need to know how soap works.
@@larrysmith8138 Chelation (by chelator) and micelle formation (by surfactant) are two completely different things. EDTA is no surfactant and it does not form micelles.
@@user255 In fact, they do create a psuedo micelle if you would just get off the definition kick. A chelating agent like EDTA forms a bond completely around said particle and prevents aggregation just like a micelle would forming its hydrophobic and hydrophilic layers around a particle. This is the property that is so great with EDTA as it keeps the particle in question "suspended" from interactions it would normally acclimate to so that your body can expel it in cases of metal poisoning. So just as soap keeps lipids from aggregating, EDTA prevents aggregation of the particle in question. Like I said, you can argue definition semantics, but in this case it is working in the same exact definition. This is what keeps book smart and street smart so very separated. I even alluded to this with my first reply to the user. Also, language is purely for taking a thought in one's self to another entity keeping the information in tact. Science dwells in keeping exact definitions pure so that we can all be on the same page. The brilliant man in the video simply used language to express an idea that that ties to the scientific definition very very well just to inform your butt.
@@larrysmith8138 _"A chelating agent like EDTA forms a bond completely around said particle and prevents aggregation just like a micelle would forming its hydrophobic and hydrophilic layers around a particle."_ Not true. Chelator forms chemical bond with a metal atom (or ion). It does not cover anything and it does not prevent aggregation. In fact you can easily crystallize some chelated metal ions. Micelle is more like mechanical structure, which arises from Van der Waals force. There is no chemical bonding. While you find superficial similarities between the two, that does not mean they are the same.
White powder joke! NICE! Thanks for sprinkling humor into the video! It is indeed a very good video, but the humor is like icing on top.
Precision in thinking, concision in style, just delightful to watch!
I learned so much. thanks a lot for this. You have a superhuman ability to predict the questions arising from your presentation and answering them then and there.
As a mechanical engineer and a person who is hungry for learning, I follow your projects with pleasure, your scientific methods open my horizons. Thank you from the heart, I wish you good health.
This channel really makes you feel you are investing time learning something instead of wasting it. Terrific!
Not everyone rerolls.
@@NunchakuJutsu I don't. My Druid is king! even if I don't play anymore. Still king. I know it, you know it, Ureroll : )
Thank you for helping to rekindle my love of science and tech! I really, REALLY appreciate videos like yours that are evenly paced, no unnecessary music or sound effects or trying too hard to be funny. It's just so nice being able to listen to you speak without all of those things that normally so clutter up other science & tech videos on here. Your videos are so well edited too, speaking as someone who edits video for work! It's an artform to get cuts to feel like they don't take anything away from what's happening, or interrupt the flow. Thank you!
Wow! Thank you.
I appreciate your channel, how thorough you are with your explanations, and how much time was spent on painting alone.
Thanks!
Low-key you're one of the few people I look up to. Thank you for everything you have shared and contributed to make the world better. You're under no obligation, but please keep going. You're awesome, chemistry is awesome. I love how you approach and dispell ignorance. I love that you're tackling HVAC without using exotic coolants to pump heat.
To be so factual, informative, and educational AND blow it out of the water with that humor near the end. I laughed until I cried and STILL came away with a higher, more broad knowledge base. Awesome work, it would be an absolute thrill and honor to spend time around y'all
Lobe your format. And the simple and very explanation based thoroughness of of this type is really well done. And I just recently found this type of paint and it is very interesting and use of which could really be used in alot of different formats.
I love this as a lecture video. It's interesting enough to keep you going, with enough quality to keep you going.
That combination of food, technology and chemistry really peaks my interest and I would love to see more on this subject.
Will do!
This channel deserves 10x the subscribers it currently has. So calm and clear talking (not always the case in other popular channels) and clear explanations!
Thank you so much for the amazing information you’ve shared with us, this is literally the best science & education channel on KZhead 👍
This channel is absolute GOLD. I can't believe this type & quality of content is free. AMAZING
To me it seems like mass produced cladding panels of the super reflective material would be ideal as painting a whole structure 20 times definitely seems like a lot of work, but if it was pre manufactured modular boards or something that could just be added on like insulation that seems really viable. Great video!
It makes more sense just to sell the paint, panels aren’t necessary
Divide the structure into twenty sections. Size the sections such that by the time a full coat has been applied to all 20 sections, the first section is dry. Repeat procedure. At least then you aren't waiting between coatings. If the structure is too large, such that the first section is too dry by the time the last section has been coated, then add additional personnel. :) Honestly though, you are right. Prefab panels makes a lot more sense. One of the most common applications I can see for something like this will be for a rooftop, which is a surface not known for its excessive safety. 20 coats walking back and forth on a roof while being a sufficiently blended combination of bored senseless and thoroughly intoxicated seems like an excellent recipe for an ER visit, or worse. In all seriousness though, labor is more expensive than the material. Total installed cost would likely be reduced by applying the coating to several different backing materials in a dedicated automated production line, then using minimal labor to install them onto the structure. Bonus points for making the backing material serve an additional purpose such as being the roofing material itself. You can buy corrugated metal roofing pre-painted in a host of different colors. Make one of them Barium-Sulfate white.
I wish your KZhead videos were used by my science teachers, first to watch it, then to recreate it. I would have paid more attention in class and would have probably traveled a different path. You sir are a teacher of teachers!
Truest statement yet. I concur. Like many, our generation too was well...assaulted.He is indeed a teacher, of teachers. That's why he has the position. Not all of us have been so fortunate.
I can't tell how much I love this channel, You do very well!
Love the sense of humor thrown in!
Ive been researching this for months now and I'm so happy that you came across this yourself. I wanted to make this paint but lacked the confidence to do it on my own. Now with your guidance I'm excited to try this.
Just wow! Guys like you and NightHawkinLight are contributing huge chunks to domestic labs world wide. Just your developing the tech to be the best it can be for ordinary jokers out in the day to day environment blows me away. Bloody impressive effort with trying to make the best coating you could, regardless. Respect.
I know very little about chemistry and was able to comprehend everything you said. Your communication skills are impeccable.
What a material! And extra duty on the preparation, Thank-you.
Making the world a better place will take millions of different "small" contributions like this. Your videos give us confidence that it can be done if a small group of people pick it up and take it to the next level. By putting it out there, you also ensure that anyone can pick it up who is willing to do it.
Awesome! Now someone needs to sell rolls of adhesive with this paint, as well as plastic sheets with this paint, so people can easily and cheaply use them to cool their houses and other structures, without having to do the mixing and spraying themselves. And for up to 10-20 times the price of normal paint, a lot of people will end up using them in the hotter areas, especially hot-and-humid areas.
Love your content TI, one of the few out there who I fully trust to give accurate, useful, and interesting information. I dropped out of HS in 10th grade because I was constantly called stupid and was told I'd never amount to anything. Since then, channels like yours have shown me that they couldn't have been more wrong. I'm more than capable of learning some pretty robust topics, if the teacher actually has an understanding of the topics.. not just a block of text to read at me and a worksheet to pass down the line. Just rediscovered you guys along with Thunderf00t and CodysLab.. OH BABY! Its science week! Gonna throw on some coffee and binge out. I finally have some free time from work, so I'm gonna try to price out the parts I need to get my own jet engine project started using yours as a template, but with room to experiment with a few variables. I probably won't record any of the process, but if I ever finish Ill try to get a video up for ya'll to see. Keep up the fantastic work. I know there's a lot of kids out there with similar stories- content like this is invaluable. ❤
It's been a while since Ive watched your videos (I like to binge watch), and I have to say; I'm pleasantly surprised by the new, looser presentation style! It definitely wasn't needed, as I very much enjoyed the balance you struck before, but it's really nice to see you two having fun with it and showing your more humorous side. The filming and editing has also gotten very good. Again, it was perfectly good before, but I'm really enjoying the more cinematic scenes and set work. I didn't think I could enjoy you guys any more than I already did, but you've outdone yourselves. It's really nice to see a father and son duo having so much fun and being so productive together. It really is heartwarming and always inspires me to do the same with my son. Finally, I want to add: I see you as an excellent example of what I strive to be like. You share a similar philosophy of ethics, interest in science/manufacturing, sense of humor, familial goals etc., as I do. You're not only teaching me about the subjects of your videos, but you're offering a real-world depiction of what I've always hoped to achieve in my personal life. I couldn't appreciate you guys more! Thanks for everything! Truly.
YES!
Warms my heart that there's wholesome, intelligent role models like Tech Ing to aspire to and learn from. Gotta love gorgeous goofy geniuns!
I cant like your comment OP bcuz its at my fave number 88 but I do like your comment despite the lack of an extra like tallied on that thumbs up button indicator / badge.
Excellent topic, demonstration and production! The perfectly nerdy comedic moments are appreciated!!! You make science and engineering beyond entertaining and fun enough to share with my non-engineer wife and kids!!!!
Im pretty impressed because i always wondered if ist really possible to show this effect in real life finding out such coating, thank you and your team for your great work, greetings from germany.
Just found your channel, thanks for sharing this experiment with us. I'm very excited to see how this shakes out in the paint industry.
I get SO excited whenever I see a new upload from y'all and the excitement is linearly proportional to the length of the video. Keep up the quality edutainment!
I don't have any of the tools or the room needed for those tools... But this process is very exciting. Not only is this doable in a relatively low tech environment, but the impressive thermal performance gives this actual tangible real life benefits. Considering the effort and stench of applying those 30 layers yourself, I hope for availability as ready to use sheets or plates at some point. Could be incredibly useful to shield homes from the sun. After all, a home fully clad in this material would be literally cooler than the air outside without any extra effort.
Agreed
@@TechIngredients hi, how much this paint last? How many years it would cool the surface?
I wish this was available on some type of sheeting. Could be a really lucrative product. It would need some longevity to be practical.
I’ll spray my home with it! I’m in Las Vegas and we could sure use the extra help with our AC bills.
Soon bro
From Portugal, Europe a big thank you for your channel!
I love you. I love your channel. Thank you both so much for giving us your time and energy to make such fascinating content.
I stumbled upon your channel a couple months back when looking up how to make a cloud chamber for a science fair-like project and I keep being amazed with the content you put out there. My ADHD brain usually makes it hard to follow lengthy videos, but your format makes it very easy to do so and every video I've watched made me look more into the things you're showcasing. Thank you very much for all the effort you're putting in your content.
In the event you happen to see this, I ended up doing something similar when trying to find an emulsion that would double as a surface coating material for my early graphene experiments and ended up using kosher glycerin as the suspension medium, 80/20 acetone/xylene as the solvent (evaps quick but not so fast that it creates surfacing issues), xanthan gum if you don't need it water-resistant, and a reptile heating pad beneath the surface to be coated to reduce layering times. I've since refined my procedure to get away from needing strong acids in the separation phase, though when you mentioned surfactants, it reminded me of a trial when I experimenting with bubble-blowing solution. It also made for an impressive base coat as it remains quite adhesive through a nice range of temperatures and can be cross-linked later to lock in the structure, not to mention it's Real cheap at the end of summer if you're looking to get it in bulk cheaper than supplies to make it can be acquired.
I learned many things I didn't know. Wow! The world is chemistry and light. Knowledge is illuminating. Thankyou.
He explains, teaches and shares the technical know-how about each project. 😎
This is a COOL video. 😎
ba dum tsss
A-yo!
The most chill video I've seen in a while.
Go home Dad, you're drunk.
This is a Dad joke.. Approved.
I think the idea of super white paint and cooling paints is really neat, but they’re going to get dirty at which point its nit more effective then normal white paint, Still obviously a lot better than a black roof .
If you can add the barium sulfate to a much more hydrophobic matrix (like PTFE, UHMWPE, or the like) and keep the IR transferring and visible light reflecting properties, and use this just as a final top coat, this will go a long way to improving the real world efficiency because then dust/dirt/debris and water will slide and/or blow off much easier and faster.
Google Resene Coolcolour paint. I don't know 8f they are doing the exact same thing but it is similar.
Great experiment and video! Thanks for sharing and teaching us! God bless You!
Every one of these is an absolute masterclass in whatever topic it covers. I once again find myself enthralled in a topic that I had no interest in previously.
Cheers for all the detailed cool concepts you guys radiate! Great practical edutainment, thought provoking stuff
I see what you did there...
Brilliant
Very good educational video! Excellent explanation to a level that I could comprehend. Thank you! I’ll be watching!
I just got one of your channel's videos on my youtube recommended page today and now im going through the entire channel and each one of these videos (atleast the ones ive seen so far) have been outstanding. And the comment section being overly positive and everyone's happy. It really is quite a rare thing on youtube and u have kind of earned it through your hard work. Hope this continues and u grow and reach much higher heights. Subscribed and turned on notifications.
Thanks and welcome!
Could you formulate a powder coating preparation? It requires a little more processing but I would think that you could apply the layers much faster with less drying time in between. There are acrylic powder coating systems out there.
I'll look into it.
It may be interesting to spray upward onto a panel and vary the charge a bit to help ensure a variety of particle size ahead of the baking/curing stage.
I absolutely love this channel. Enjoy your "supplies", you deserve it!
amazing video kept me glued till the end. and loved the drunk sketch bit near the end.
Fascinating video as always. I don't typically think of EDTA as a surfactant, but as a chelating agent. Surfactants are typically dealing with liquid-liquid or liquid-glass interfaces. I generally see surfactants in the context of some hydrophobic - hydrophilic interaction, where some hydrophobic species is insoluble in an aqueous solution and the addition of a surfactant (Triton-x, SDS, etc.) aids in dissolution.
It is used in detoxication of lead poisoning using its chelating property.
I am in the refrigeration service business and this is incredible! Refrigeration coils often placed on roofs in direct blazing sun coated with this could be many times more effective at releasing more heat if the coils where not soaking up radiant heat from the sun😮
Agreed. Maybe not many times, but it would definitely make a difference.
I love the effort and detail. Keep it going. PS I like your select of beer.
Some great visual gags in there. Love your work! Love the hair and the acting after the... refreshments, turn up haha
Another experiment that you could do with these coatings is send some samples up on a weather balloon and log the different temperatures. One of the concerns with flying stratospheric scientific balloons is the over heating of the aluminum gondola structure. When I was a part of the AESOP and LEE payload program at Bartol Research Institute, we were advised to paint any exposed aluminum with "appliance white" paint. (Sorry, I don't remember which brand so I apologize for how imprecise that description is.) It would be interesting to see how well this coating works at high altitude. One big issue might be the lack of azimuth control on small, hobby balloons. Maybe coating cylinders and stringing them vertically (to avoid shadows) would work.
it should work even better in high altitudes.
Add a dose of missile repellant..👨✈
I think you may be more concerned with egotistical politicians with their fingers on the giggle switches of their AIM-9X's 😅
I guess you have never heard the saying Use sledgehammer to crack a nut Or in today’s context Use a jet fighter to pop a balloon
Or Joe Biden administration shooting it down with a half million dollar missile…
As a pest control technician, I'm happy to see you use a properly rated mask. Far too many people walk up to me wearing surgical masks thinking it will protect them from everything and those same people I typically have to argue with to go back inside/outside/away so I can continue with the treatment.
excellent presentation. i appreciate the fact that you acknowledged, at the very end, that ambitious entrepreneurs in search of a profitable niche industry have just had it presented to them on a barium-coated silver platter.
Fascinating stuff, I love the videos you create! They’re brilliant! I am a subscriber ☺️☺️ keep up the fantastic video content
I love a creator who respects his audience and doesn't dumb it down
Each time I watch your videos, I'm always amazed that we get to watch a genius applying his talents to little projects around the home. This is the most unique channel on KZhead.
My mind is blown, I sat through the entire video, and was thoroughly impressed by the end result, not to mention the humour is right up my alley. 10/10 video imo
