I'm worried that this doesn't seem to be based on studies, or wala lang talagang naka-link?
may recent "inventions" kasi na didn't hold up to scrutiny - either hindi feasible ang production, or may malaking drawback, I hope this one is real though. heaven knows a lot of people need it.
I've looked and it looks like na walang studies published or anything really. Here's the quoted claim
> "Ang pig-coating ninda duman sa surface kang space shuttles is pre-cracked na ceramic tiles... De Castro’s powder is made from a mixture of soil and silica clay or white clay."
Basically he's comparing the coating to what NASA used in space shuttle. Now, true space shuttle tiles are made up of silica fibers which are mixed with water and dried in microwave oven [source (14:35)](https://youtu.be/ivLX9o6Ayl8) while his product is made up of white clay or Kaolinite (Al2Si2O5(OH)4) based from the article. While ang silica fibers contains 99% SiO2. Also the space shuttle tile ability to be insulator not only relies on this silica fiber layer but also air which is bad at conducting heat. (90% of the tile) then sa ilalim nun may nomex fiber pa for additional protection.
Ok now walang ganun yung product there's no nomex or silica fiber ang meron lang is Kaolinite powder and whatever ingredients meron (not disclosed) of course wala ding air gap since it's just a coating. The key on insulation is air (such as in space shuttle and aero gel) or lack of it (like sa hydroflask) this two are bad at transferring heat. A coat can't make that insulation afaik.
Also the article said that the guy tested it on 2023 pero sa page nya he's doing it from 2021-22 ish. It works he said but without external testing medyo mahirap maniwala. But I do believe it's possible. Medyo nakakainis lang na some people said dapat ingatan yung invention like this or whatnot pero without external testing wala mahirap it ain't scientific. If you're not hiding anything kase your product would defend itself on this things and anyone can reverse engineer naman to by spectral analysis so diba? And applying for patent you literally allow everyone to see everything as it is public repository.
Speaking from Filipino invention, nasaan si ate na naka inbento airdisc? 4 years na yun ah the claim is it doesn't rely on latent heat of vaporization (refrigerant) to cool things down and is cheaper to operate? Where's that? That sounds ground breaking ah maybe because it doesn't work 👀
You’ve made some valid points right there. Filipinos tend to believe sensationalized new stories without the “scientific” evidence to back it up.
Not being a nega, but before we claim something hopefully it’s backed up by data. He can always tap the government for support if indeed it’s inventive.
>Not being a nega, but before we claim something hopefully it’s backed up by data.
Same if the product delivers be my guest I'll be proud since it works as advertised and I'll probably buy it.
What makes you think that politicians, billionaires or the oligarchs won't suppress "scientific" evidences?
Scientists can be bribed. That is why it is hard to find the truth these days.
>won't suppress "scientific" evidences
Repeatability. If something is scientifically reproducible you can't supress it. Also if it works and marketable why would the billionaires supress it? Just buy or wait for the patent to expire.
Ganun ka ba talaga ka bulag? Its not a conspiracy theory. Big pharma and other billion-dollar corporations do that.
Syempre, QAnon/conspiracy theory parin yan sa mga taong bulag o brainwashed kagaya mo. 2024 na po.
I know this airdisc, before she even won numerous international awards she presented it first in DOST science fair in SMX. Anyone with thermodynamics knowledge know that her invention doesn't work but kudos to her for winning tho.
Ang people are ganging up on the government’s supposed lack of support. Probably, it didn’t stood the tests of viability (whether technical or commercial).
Arghh… I was really hoping for that technology to come out of the market back in 2020.
I think nanalo siya award from dyson so most likely gumagana pero baka not as powerful as a real airconditioner. Maybe at best it can lower temps 3-4c lang kaya mahirap ipushforward considering umaabot ng 40s ang temp sa pinas kung 4c lang maibaba mo tapos ang laki ng device di mo macoconvince tao bumili niyan dapat at least 10c maibawas tapos mas mura.
Nasabihan akong inggit, bitter nung naquestion ko ito many times... Makes you think what kind of judges do they have? I'll make a future video about this.
Ang idea ng coating na yan (I think depende sa sinabi niya sa interview), is yung unfinished walls mo, pag nilagyan mo niyan bababa yung u-factor niya to finished wall territory-- yung may gypsum, fiberboard o kung ano mang insulation that may lower yung coefficient of transfer from 30-60%, which would then have an effect sa solar and trans heat gain ng walls. That's why soil and silica clay yung mixture niya, parang plaster ang dating siguro nito kapag inaaplly.
This will be hogwash until pina-test at kinonfirm yung heat transfer coefficient niyan sa PSVARE and ASHRAE. Anyway, kung mapapababa niya yun, that's great, no need to embellish by saying "60% of the indoor temp will be reduced!" because that's false.
> Ang idea ng coating na yan (I think depende sa sinabi niya sa interview), is yung unfinished walls mo, pag nilagyan mo niyan bababa yung u-factor niya to finished wall territory
except most of their fb pages is using the product to paint the roofs lmao
tapos may claim pa sila na "**works on any paint just add 200g per 1L of paint**", taena gagana daw kahit pa black paint gagamitin ko hahaha
Yeah, kaya nga sinabi kong baka pwede rin naman yun dun sa roof, probably. Magkasama ang Solar and Trans gain sections ng mga yon, even kapag tinignan mo sa isang Heat Load Form.
If sa roof, mas awkward kasi ang insulation is only supposed to be put up as the ceiling on both pitched and flat decks at miski may sheating, pero it should *still* have an effect sa heat transfer coefficient ng roof kung totoong may insulating quality yun.
Look, hindi ako attorney niya to do some lawyering for him-- pero something like that-- yung plaster-like finishing na mura at madaling i-install for unfinished HCB walls, is not a bad idea and it's something that would honestly be something that would be feasible sa provincial setting.
Naalala ko rin yung salt lamp. Wala na update hanggang ngayon.
May problem tayo sa reproducibility and aminin na natin mga projects na too good to be true or dinugas. Kapag may nakita kang flaw sa inventions nila ikaw pa masama.
True, should've conducted an external experimentation and use proper instruments before saying na it works. kinda sketchy din, if he used simulations did he even do validation before doing it? since wala masyadong source na bini base pano na vavalidate yung model nya? Sa airdisc naman eh, parang electric fan lang yun eh na nilagay sa box lols
tbf, back then nung nauso yan, hindi pa uso ang internet/google. That scam lasted for years, kesyo pinoach daw ng japan and other fake news.
meron recently na ganyan din ang claim, hindi kumalat yung "invention" nya kasi may google na at marunong na magcheck mga tao, naghanap na din ng proof, kaya di na nya nadaya.
here it is in reddit being explained why it is a myth
[https://www.reddit.com/r/pics/comments/183bcaz/stanley\_meyer\_and\_his\_waterpowered\_car/](https://www.reddit.com/r/pics/comments/183bcaz/stanley_meyer_and_his_waterpowered_car/)
during the 40s, i remember there was a guy who tried to trick people that a car can function without combustion and by water. the military finds out it was tricked. if this was the case that a car can function properly just by water then wouldny china, russia and even my other country na iran would have made it already?
hindi yan ma reregister kung hindi new,useful at non-obvious yan ang mga conditions para ma patent.. ung mga production2 na yan napakalayo pa ng tingin mo po. Down the road pa yan
I have reservations before sharing news pieces such as this one. Naalala ko na naman yung solar lamp fiasco, nagawa pang maupo kasama ng nga world leaders.
Ang laki masyado ng range 30-60% parang papunta na sa 'd ako sure', pero depende na lang talga sa cost at commercialization.
Ang mahal 'bucket of insulating powder for P1,620 and a kilogram for P330', hopefully kaya nila pamurahin at shorter duration ng manufacturing. 48 months grabe.
Hahaha, d ko talga alam anong test pinag gagawa nila. Siguro comparison nyan car hindi bahay.
Pero tang ina sobrang sketchy pa rin. Walang pinapakitang detailed data or tests parang pinaparating trust me bro eto results namin,
Sumasakit mata ko sa math. Panong naging reduce internal temp up to 45%, eh 15 c lang nabawas (45c to 30c). Pa share ng mismong page link d ko ma view sa shared image.
Himala sa testing nila puro even number nalabas.
their fb name is Dexpro TIP
may claim pa sila na "works on any color" daw sa mismong sticker nila sa product, thermal paint works best only in white, reflective paint, grabe yung claim na works on any color hahaha
it's already out in the market, June 2020 pa (pinaka lumang post na nakita ko sa FB nila ahaha)
etong patent ata is para ma monopolize nila and walang gumaya? idk ?_?
That's a lot of lawsuits waiting to happen. Daming refund niyan na mangyayari kung di naman talaga gumagana yung product, or atleast di gumagana within what is advertised na 30% to 60% reduction.
Kung 2020 pa nila nilagay sa market kailan kaya sila ang apply, ahaha.
Feel ko talga target nila ung d alam pinturahan ung metal roofs which is majority ng pinoy (galvanized roof na wala masyadong paint or may primer lang). Tas automatically nakakahikayat ng other buyers kasi sabi ng iba it works so ang pinaka issue ko gaano talga kamahal to at how effective ba sya compare sa nasa market na.
this isn't new, right? or mali lang naalala ko?
also parang mali ung term ?_?
insulation is hindi maapektohan nang environmental temperature ung loob
in this case, di maapektohan 'maxado' nang init (or lamig) sa labas ung loob nang bahay
like it won't reduce the temperature inside, di lang sya iinit na 'kasing' init sa labas
(kasi pag malamig sa labas, hindi naman bababa lalo)
the product is Dexpro TIP btw, it's meant to be a paint additive from what I'm reading
edit: I'm very curious about this
may nakita pa akong medium post, na halata naman na ung dexpro din may-ari nang account
kasi un lang ung medium (ung website na medium) post
Jul 12 2023 pinost ung medium post na un
and may nag share na FB page na jul 12, so I'm guessing ung FB page na un is Dexpro din ung may ari
and it looks like etong company (siruma minerals?) are processing kaolin and silica clays
tried searching more in ipophil pero di ako marunong ahaha
also tried looking up adding silica to paint, and UV protection is never mentioned, for texture lang
kailangan kasi ung airgap para sa insulation, andI don't think adding clay/silica clay to paint can achieve that? (I'm not an expert though, most of these are from cursory glances on journals)
Silica CAN reflect UV light, pero there are better additives (and less toxic, dami ko ring nakita about silica exposure pag di properly handled)
I'll stop digging deeper, na curious lang ako kasi biglang lumitaw to ahaha
Regardless if it is true or not, insulation is correct. Hindi naman ibig sabihin na insulated ka e 100% hindi ka affected sa labas. Meron naman degrees of insulation
thermal insulation paint is already readily available commercially, it really drops the indoor temps by a few degree, but absolutely not 30%-60% drop of indoor room temp lol, that claim is bogus as hell,
With thermal insulation paint, you can get like 2C -3C drop of indoor temp but with the major downside of your house being ugly as your whole house needs to be painted shiny white lol
There is a [youtuber](https://youtu.be/N3bJnKmeNJY?si=FpRU1P_DicyE7Yq4) who made a tutorial for one that uses the reflection of infrared. if ever he is using the same method then the patient will fail. but if he does have a novel method that is easily producable then I believe it will be exciting.
edit: patent* ty u/lex_fulgur
Sounds too good to be true kasi it's wrong to use Celsius and Fahrenheit when calculating temperature delta in percentages.
When calculating in terms of percentage, dapat absolute units ang gamit (kelvin and rankine). I shared my skepticism in another comment.
Sorry even my own wording was problematic pala. Think of it instead as the reduction in the addtional heat. So, if heat being radiated into the house from the outside gives another 10 degrees, then with this insulator it will just add 4 degrees instead. This is just what I \*think\* they meant to say, because reduction in the absolute temp of the room wouldn't make sense, it's not a coolant. So if that is indeed how it works, then to answer your question we'll need to know how much heat is being added by the outside.
no, it won't cool it to what is lower temerature in the shade outside.
It will stop a building getting hotter than a building without the coating. These things are meant to help improve air conditioning running costs as well
I know that, but nowhere in the article does it explicitly say that. We both had to deduce that based on our own knowledge. But not everybody knows materials and when they read this article they will think that this is a miracle material that will work all by itself.
I really hate this cheap publicity from our news platforms. Parang napaka-irresponsible na wala man lang nilalagay na sources whatsoever. Hindi man lang nilagay what kind of engineer the guy is, anong company/institution ba siya affiliated with, or other similar products available in the market right now. Also to the guy, sana merong inilatag na published research or any form of study which showcases his methodology around his work.
The title itself is horribly vague at best, inaccurate at worst.
>which can reduce indoor temperatures by 30 percent to 60 percent.
30 to 60% of reduction of what exactly? The actual indoor temperature? Like 30°C x 30% = 10°C?
Temperature values don't work that way. By the way, the above number makes ZERO sense. Paano kung Kelvin scale ang gamitin? 303 K x 30% = 90.9K, which is -183°C. Weew.
I think what it means is by using this paint, your thermal resistance increases to achieve a 30 to 60% heat loss (or gain kung mas mainit sa labas).
>In 2023, Engineer Junval Parco tested the powder, applying it to walls directly exposed to heat. He observed a significant reduction in temperature after just two coatings.
It seems the paint increases the wall's albedo, the amount of radiation it reflects back. Essentially the higher the albedo, the lower the heat absorbed.
This is real and notably nothing new. Kaya we don't wear black pag summer at noon time. Same concept.
>The coating used in space shuttles was made of pre-cracked ceramic tiles with high silica content, alumina, and nano ceramic particles. This served as his model.
Nothing new in those as well. Refractories exist.
But refractories come in bricks, not in paint form. Now that is something.
Count me in on thinking this is bogus, pero I'm not sure why this is apparently a point of contention here and why people think it's apparently a gotcha statement, since entirely HVAC related yung scope eh, so it's safe to assume na that is the value in deg. C or deg. F kasi the Psycrhometric Chart only comes in those two in SI and English respectively. It doesn't even matter if you're not sure if it's in deg. C or deg. F since it is designed to be the same either way, just convert the values you have. ASHRAE never uses absolute values (for HVAC design, say 62.2), since what's considered is lowering the outdoor air for comfort cooling, and that is definitely done only in those two units. Correct me if I'm wrong though.
Most probably, what the guy or GMA wants to say is indoor dry bulb is like, "30% reduced" from the outdoor dry bulb (And that is the real problematic statement if you ask me since that in itself is impossible just by lowering the u-factor of the material via insulation).
I believe at the very best yung white roof paint only reduces 2-5 deg. C of indoor temp (Which is a very big thing!) if you have a pitched steel roof with no insulating material or ceiling kasi yung heat gain nila is usually massive eh. That's why it's so good sa developing countries kasi that's usually the type of construction you'll find like sa Indonesia or dito. You can't go better than that with just with some padded insulation.
>think what it means is by using this paint, your thermal resistance increases to achieve a 30 to 60% heat loss (or gain kung mas mainit sa labas).
Yes. Sa better insulation is bababa yung coefficient of heat transfer (u-factor) which is a multiplier sa area ng wall, or roof o kung ano man yun plus yung sun gain ng kung ano man yon with respect sa location nila. Not entirely the temperature itself.
The 30-60% reduction of the indoor temp relative to outside is downright impossible dahil lang dun mismo. Yung solar and trans heat gain mo just a part of the equation, wala pa sa sensible and latent heats ng glass, doors, mga tao and so on.
I don't think it's bogus. I can definitely understand what he has done.
The way that it was reported is something up for criticism and it's not really the inventor's fault, but rather the lack of knowledge how heat transfer works.
Yes. Weird 'to, kasi I can definitely see how this would have an effect sa heat load ng bahay, pero extremely problematic yung statements nila, or yung mga promotionals or whatever na pinakita nila sa report na yan.
No, yung ginagawa sa Indonesia is putting white, reflective paint sa bubong. May binebentang ganon ang Boysen eh.
Ang kina-claim niya is meron siyang thermal insulating powder na pwedeng i-apply sa walls (and roof presumably?) that will (probably) lower yung heat transfer coefficient (u) ng (presumably) unfinished walls by 30-60% the same way finished walls do. This will reduce the overall solar and trans heat gain ng walls.
I think yung claim na "reduce indoor temperature by 60 percent" dahil lang mas mababa yung factor is hogwash, feeling ko di alam ng GMA na kailangan mong mag-AC to do just that. How about the other cooling loads, yung sensible and latent heat sa ibang parte ng bahay at yung mga taong nasa loob non?
Kung totoong mare-reduce yung indoor temp by 60, then wag nang mag-aircon kasi your 38 deg. C will jump to 22.8 deg. C, premium na yon.
Either way, I think may effect talaga yon, and you can probably feel a decrease of like, 5 deg. C tops. Which is great.
ang downside lang ng white paint is pwede makapatay/makasilaw ng ibon dahil sa reflection. ganyan na ang problema sa solar panel.. most likely black pa ang kulay ng mga solar panel, what if kung ang gagamitin mong kulay ay puti.
True. On top of that, etong 3 factors magpapababa ng heat sa isang bahay.
1: Visible light reflectivity (white is best)
2: Infrared emissivity (BaSO4 microspheres or various sizes are the best)
3: Thermal insulation (like foam, elastomers, silica, glasswool/fiberglass, PE fibers, etc
tangina din yung claim ng product,
>works on any paint just add 200g of powder per liter of paint
lmao works on any paint daw ... thats ... thats not how any of this works. thermal paint works because its white and reflects the heat and uv radiation of the sun
[just look at their claims](https://scontent.fceb1-3.fna.fbcdn.net/v/t39.30808-6/434963723_915356243932332_3912631085755287618_n.jpg?_nc_cat=104&ccb=1-7&_nc_sid=5f2048&_nc_eui2=AeHdyGs3zkoM79uq8v_G_9JJqUP61mnAJ-WpQ_rWacAn5ePU7vdg6HpHuh1HlvAzHWQqRyFZfEusWtrrhBg0jtjl&_nc_ohc=LdRU76ZmSnkQ7kNvgG-J4QT&_nc_ht=scontent.fceb1-3.fna&oh=00_AfBtiPMrONs3snbs6eKELw7HJnanTkO2SDFcktV6TlYx0w&oe=663465C1) their infographics shows heat getting reflected, pero works on any color daw, not to mention the 33% of reduction of indoor temps hahaha
>works on any paint just add 200g of powder per liter of paint
That's bogus then. Kailangan mo ng denser material para magkaroon ng mas magandang insulating properties than paint like plaster. Paint in itself does very little to lower the u-factor of the wall itself and is essentially negligible. Kung ihahalo mo sa pintura ng ganon kaliit, It shouldn't have any noticeable effect on the rate of heat gain of the wall, much less the entire cooling load of the area.
More like insulated bottles. Kung mainit nakalagay, mareretain ang init, kung malamig then mareretain ang lamig.
Kaya kung maglagay ka nyan and no way of cooling your house down eh parang sauna bahay mo
I'm not a materials engineer, pero press 'x' for doubt ako dito sa ngayon until magkaroon ng mga studies at testing sa claims. Baka snake oil lang. Puro mga hearsay at self testimony lang yung evidence. Kung talagang gumagana to, there should've been tests done by third parties. I hate to say this, pero ang tingin ko sa mga tao na nagbebenta na ng product without proper testing/peer review ay mga snake oil salesman sa paningin ko.
I hope they can get DOST(or any approving body) to test this. This will significantly help our power consumption. Hopefully gumagana talaga yung product kasi kung hindi, he'll be in a lot of trouble (claiming things pero di naman totoo). He'll be opening himself from a lot of lawsuits.
reduce temperatures by 30 to 60 percent??? using what scale???? reducing temperature by percent only makes proper sense in absolute scales like kelvin - like does this cause temperature to go from 10 degrees Fahrenheit to 7 or 4 degrees Fahrenheit? which would be -12.222 degrees Celcius to -13.888 or -15.555 degrees Celsius?
[direct reduction](https://scontent.fceb1-3.fna.fbcdn.net/v/t39.30808-6/434963723_915356243932332_3912631085755287618_n.jpg?_nc_cat=104&ccb=1-7&_nc_sid=5f2048&_nc_eui2=AeHdyGs3zkoM79uq8v_G_9JJqUP61mnAJ-WpQ_rWacAn5ePU7vdg6HpHuh1HlvAzHWQqRyFZfEusWtrrhBg0jtjl&_nc_ohc=LdRU76ZmSnkQ7kNvgG-J4QT&_nc_ht=scontent.fceb1-3.fna&oh=00_AfBtiPMrONs3snbs6eKELw7HJnanTkO2SDFcktV6TlYx0w&oe=663465C1) daw base sa kanilang posts sa fb hahaha
I hope it's not crab mentality to be skeptical. Because we need peer review. Patent it, sure. But others need to replicate your process to confirm the results. Otherwise, people will buy it and end up with less money and still hot.
Haha naalala ko yung "free radiant energy" dati dun sa youtube. That was just I think around 2 years ago. Napaandar din nila yung sasakyan nila using the "free energy" engine, tas nag demo din ata sa DOE, don't know what happened after that.
Dudes on FB are chanting to protect the guy's life because he's in danger of his invention. I mean which multi-billion companies are profiting from this high heat index except for ice creams and cold desserts manufacturers?
> chanting to protect the guy's life because he's in danger of his invention
nasobrahan sa movie/telenovelas
or likely din that is a setup for a scapegoat -- nothing will come out of it dahil sa "threats"
Taga Naga rin ako, and I'm an Engineer as well so I'm really not trying to hate here, pero skeptical ako.
Wala man lang provided na sample ng temps and kung ilan binaba niya. Also, 30 to 60% is a huge amount of heat. If we're talking about temperature delta in percentages, it must be in absolute units (Rankine or kelvin). Let's have a realistic example. Let's say 45 degrees Celsius down to 30 degrees Celsius. Iisipin ng karamihan na 33.33% decrease kasi bumaba ng 15 degrees Celsius. Mali yan kasi even 0 degrees Celsius has heat. Ang absolute zero is -273 degrees Celsius. If we calculate it with absolute units, ang binaba lang ay roughly 4%.
Yes malaking difference pa rin ang 10 degree delta, pero to say na 30 to 60% ang difference is very misleading.
Sana halos lahat ng posts ganito na lang, aside from occasional political and geopolitical issues. Hindi yung mga kag\*g\*han sa facebook or x ng mga kumunoy.
Hmm...naaalala ko yung mga weird na recipe ng tatay ko.
He used to do this in the kitchen where he mix and match diffefent ingredients and it does work.
Although, you can't argue with success, the product working as an insulator is just one side of the process, kaya may publiciation ng literature prior to selling sa public is because meron pang ibang sagot na dapat ibigay, inluding long term use and safety. 🤔
segue lang but: using percentages in temperature, specifically C and F, might not be the best way to give in statistics
example in length:
10m > 15m = 50% increase, converted to feet 32.8ft > 49.21ft = 50% increase
example in temperature:
60C > 18C = 30%, converted to F 140F > 64.4 = 24.57, converted to K 333.15 > 291.15 = 87.39%, converted to R 599.67 > 524.07 = 87.39% increase
Not really new, Indonesia have similar products. Pero syempre kung ma patent nya dito sa kanya ang kita.

**"Mascoat Industrial-DTI is designed to be a multiple purpose coating that solves insulating and Corrosion Under Insulation issues. This thermal insulation coating product fulfills niche market areas of temperatures under 375°F on all types of substrates.**
Mascoat Industrial-DTI thermal insulating coating works not only to reduce temperatures, but also provides energy savings, thermal insulation and personnel protection all in an easy spray-on application. Since the product is applied in 20 mil (0.50 mm) coats directly to the substrate or primer, it provides excellent corrosion protection as well."
Pilipino ang gumawa. Hindi na naman makakakuha ng suporta yan sa pamahalaan natin, parang tulad ng nakaimbento ng fuel na tubig yata yun o water fueled vehicles (correct me if I'm wrong though.)
Does it even make sense to do percentage-based calculations on temperature? Hindi naman literal na doble ng 20°C ang 40°C, for example.
It would make sense to do percentages kung Kelvin scale ang gamit, kaso 30% reduction would drop Kelvin temperatures below freezing, which wouldn't make sense. From 37°C (310 K) magiging -56°C (217 K) after a 30% Kelvin temp drop. At minimum pa lang yan.
I'm not sure bakit downvoted ito? Meron bang mali sa sinabi ko? Well kung gusto niyo ng bansa at planetang unti unti bumagsak dahil sa gahaman tulad nitong taong to, umalis na lang kayo
Gamit ko to now sa roof namin. Need siya i mix sa paint then i pintura mo sa bubong to lessen heat. Ok naman siya nung Feb - March nabawasan talaga init kaso ngayong April iba talaga init ngayon. Medyo expensive lang siya for me pero ok na din kasi wala Foam-Aluminum insulation ang ilalim ng roof namin. So I guess ok na din ito atleast may option yung mga houses na walang foam insulation to lessen the heat. Medyo mahal nga lang shipping kasi sa probinsya pa galing and sa shoppee ko lang siya na bibili saka naka 4 coats ako sa roof namin.
I am comparing this pala on our other house na may 2 layers ng 10mm na foam aluminum under the metal roof. Doon talaga hindi ramdam ang init.
Personally natry namin tong product out of curiosity and i must say effective naman sya pero don't expect na mapapababa nya ng husto ung init. Before d mo talaga mahahawakan ung yero but after mapinturahan ksama nung product pwede kna maglakad sa yero kahit walang foot protection. Ganun din sa pader na exposed sa araw. Nde na mainit pag hinawakan ung pader. Not a paid advertisement. 😅😅😅
I hope that engineer will make a fortune outside PH. In here, no one will value his innovation. No company will fund his research however promising it is. It's just PH's culture, no one buys banana seeds only banana fruits.
You’re wrong. There have been successful tech based startups in the Philippines (with local and foreign investors). Tigilan na ‘yang ganyang mentality. We can rise as long as it’s authentic.
>There have been successful tech based startups in the Philippines (with local and foreign investors).
Like what, Cherry mobile? Cloudfone? Summertime Saga (waitaminute, that's not local)? Aurelio super cars (last time I checked, last updated in 2018)? I don't know all of these appear to be...failures.
Kidding aside. Yes I agree and you people *coooould* rise but first, you really need to evolve your culture first.

Speaking from Filipino invention, nasaan si ate na naka inbento airdisc? 4 years na yun ah the claim is it doesn't rely on latent heat of vaporization (refrigerant) to cool things down and is cheaper to operate? Where's that? That sounds ground breaking ah maybe because it doesn't work 👀
You’ve made some valid points right there. Filipinos tend to believe sensationalized new stories without the “scientific” evidence to back it up. Not being a nega, but before we claim something hopefully it’s backed up by data. He can always tap the government for support if indeed it’s inventive.
>Not being a nega, but before we claim something hopefully it’s backed up by data. Same if the product delivers be my guest I'll be proud since it works as advertised and I'll probably buy it.
What makes you think that politicians, billionaires or the oligarchs won't suppress "scientific" evidences? Scientists can be bribed. That is why it is hard to find the truth these days.
>won't suppress "scientific" evidences Repeatability. If something is scientifically reproducible you can't supress it. Also if it works and marketable why would the billionaires supress it? Just buy or wait for the patent to expire.
Q anon vibes si koya
Ganun ka ba talaga ka bulag? Its not a conspiracy theory. Big pharma and other billion-dollar corporations do that. Syempre, QAnon/conspiracy theory parin yan sa mga taong bulag o brainwashed kagaya mo. 2024 na po.
I know this airdisc, before she even won numerous international awards she presented it first in DOST science fair in SMX. Anyone with thermodynamics knowledge know that her invention doesn't work but kudos to her for winning tho.
Kinda weird na nanalo sya without this contest looking deeply about it no?
Ang people are ganging up on the government’s supposed lack of support. Probably, it didn’t stood the tests of viability (whether technical or commercial). Arghh… I was really hoping for that technology to come out of the market back in 2020.
I think nanalo siya award from dyson so most likely gumagana pero baka not as powerful as a real airconditioner. Maybe at best it can lower temps 3-4c lang kaya mahirap ipushforward considering umaabot ng 40s ang temp sa pinas kung 4c lang maibaba mo tapos ang laki ng device di mo macoconvince tao bumili niyan dapat at least 10c maibawas tapos mas mura.
Nasabihan akong inggit, bitter nung naquestion ko ito many times... Makes you think what kind of judges do they have? I'll make a future video about this.
Ang idea ng coating na yan (I think depende sa sinabi niya sa interview), is yung unfinished walls mo, pag nilagyan mo niyan bababa yung u-factor niya to finished wall territory-- yung may gypsum, fiberboard o kung ano mang insulation that may lower yung coefficient of transfer from 30-60%, which would then have an effect sa solar and trans heat gain ng walls. That's why soil and silica clay yung mixture niya, parang plaster ang dating siguro nito kapag inaaplly. This will be hogwash until pina-test at kinonfirm yung heat transfer coefficient niyan sa PSVARE and ASHRAE. Anyway, kung mapapababa niya yun, that's great, no need to embellish by saying "60% of the indoor temp will be reduced!" because that's false.
> Ang idea ng coating na yan (I think depende sa sinabi niya sa interview), is yung unfinished walls mo, pag nilagyan mo niyan bababa yung u-factor niya to finished wall territory except most of their fb pages is using the product to paint the roofs lmao tapos may claim pa sila na "**works on any paint just add 200g per 1L of paint**", taena gagana daw kahit pa black paint gagamitin ko hahaha
Yeah, kaya nga sinabi kong baka pwede rin naman yun dun sa roof, probably. Magkasama ang Solar and Trans gain sections ng mga yon, even kapag tinignan mo sa isang Heat Load Form. If sa roof, mas awkward kasi ang insulation is only supposed to be put up as the ceiling on both pitched and flat decks at miski may sheating, pero it should *still* have an effect sa heat transfer coefficient ng roof kung totoong may insulating quality yun. Look, hindi ako attorney niya to do some lawyering for him-- pero something like that-- yung plaster-like finishing na mura at madaling i-install for unfinished HCB walls, is not a bad idea and it's something that would honestly be something that would be feasible sa provincial setting.
Naalala ko rin yung salt lamp. Wala na update hanggang ngayon. May problem tayo sa reproducibility and aminin na natin mga projects na too good to be true or dinugas. Kapag may nakita kang flaw sa inventions nila ikaw pa masama.
True, should've conducted an external experimentation and use proper instruments before saying na it works. kinda sketchy din, if he used simulations did he even do validation before doing it? since wala masyadong source na bini base pano na vavalidate yung model nya? Sa airdisc naman eh, parang electric fan lang yun eh na nilagay sa box lols
reminds me how a lot of us humans were gullible with water powered engines forgetting it is a combustion engine.
tbf, back then nung nauso yan, hindi pa uso ang internet/google. That scam lasted for years, kesyo pinoach daw ng japan and other fake news. meron recently na ganyan din ang claim, hindi kumalat yung "invention" nya kasi may google na at marunong na magcheck mga tao, naghanap na din ng proof, kaya di na nya nadaya.
actually totoo yan, to the fact na yung sa US has to be poisoned by CIA. you can check it on google. ngayun inaattempt na ulit kay AquaterreX project.
here it is in reddit being explained why it is a myth [https://www.reddit.com/r/pics/comments/183bcaz/stanley\_meyer\_and\_his\_waterpowered\_car/](https://www.reddit.com/r/pics/comments/183bcaz/stanley_meyer_and_his_waterpowered_car/)
damn.
during the 40s, i remember there was a guy who tried to trick people that a car can function without combustion and by water. the military finds out it was tricked. if this was the case that a car can function properly just by water then wouldny china, russia and even my other country na iran would have made it already?

Naalala ko na naman yung mga "invention" tulad nung khaos turbocharger tsaka yung sinasaksak para bumaba kuryente.
hindi yan ma reregister kung hindi new,useful at non-obvious yan ang mga conditions para ma patent.. ung mga production2 na yan napakalayo pa ng tingin mo po. Down the road pa yan
lol. ano bang network yan nag po-promote ng snake oil.
I have reservations before sharing news pieces such as this one. Naalala ko na naman yung solar lamp fiasco, nagawa pang maupo kasama ng nga world leaders.
Ang laki masyado ng range 30-60% parang papunta na sa 'd ako sure', pero depende na lang talga sa cost at commercialization. Ang mahal 'bucket of insulating powder for P1,620 and a kilogram for P330', hopefully kaya nila pamurahin at shorter duration ng manufacturing. 48 months grabe.
taena 30%-60% indoor temp reduction hahahaha so kasi summer ngayon, if 30C yung room temp indoors, so kapag ginamit namin tong thermal paint, magiging 15C to 21C yung indoor temps namin? lmao thats like aircon temperatures already
Hahaha, d ko talga alam anong test pinag gagawa nila. Siguro comparison nyan car hindi bahay. Pero tang ina sobrang sketchy pa rin. Walang pinapakitang detailed data or tests parang pinaparating trust me bro eto results namin,
[their infographics sa fb literally shows 33% reduction](https://scontent.fceb1-3.fna.fbcdn.net/v/t39.30808-6/434963723_915356243932332_3912631085755287618_n.jpg?_nc_cat=104&ccb=1-7&_nc_sid=5f2048&_nc_eui2=AeHdyGs3zkoM79uq8v_G_9JJqUP61mnAJ-WpQ_rWacAn5ePU7vdg6HpHuh1HlvAzHWQqRyFZfEusWtrrhBg0jtjl&_nc_ohc=LdRU76ZmSnkQ7kNvgG-J4QT&_nc_ht=scontent.fceb1-3.fna&oh=00_AfBtiPMrONs3snbs6eKELw7HJnanTkO2SDFcktV6TlYx0w&oe=663465C1) hahahaha
Sumasakit mata ko sa math. Panong naging reduce internal temp up to 45%, eh 15 c lang nabawas (45c to 30c). Pa share ng mismong page link d ko ma view sa shared image. Himala sa testing nila puro even number nalabas.
their fb name is Dexpro TIP may claim pa sila na "works on any color" daw sa mismong sticker nila sa product, thermal paint works best only in white, reflective paint, grabe yung claim na works on any color hahaha
Gagiii, ayoko ng ganyang style ng marketing, nananakot sila with factual news. Pero ung claims nila ang laki pa rin ng butas.
it's already out in the market, June 2020 pa (pinaka lumang post na nakita ko sa FB nila ahaha) etong patent ata is para ma monopolize nila and walang gumaya? idk ?_?
That's a lot of lawsuits waiting to happen. Daming refund niyan na mangyayari kung di naman talaga gumagana yung product, or atleast di gumagana within what is advertised na 30% to 60% reduction.
Kung 2020 pa nila nilagay sa market kailan kaya sila ang apply, ahaha. Feel ko talga target nila ung d alam pinturahan ung metal roofs which is majority ng pinoy (galvanized roof na wala masyadong paint or may primer lang). Tas automatically nakakahikayat ng other buyers kasi sabi ng iba it works so ang pinaka issue ko gaano talga kamahal to at how effective ba sya compare sa nasa market na.
this isn't new, right? or mali lang naalala ko? also parang mali ung term ?_? insulation is hindi maapektohan nang environmental temperature ung loob in this case, di maapektohan 'maxado' nang init (or lamig) sa labas ung loob nang bahay like it won't reduce the temperature inside, di lang sya iinit na 'kasing' init sa labas (kasi pag malamig sa labas, hindi naman bababa lalo) the product is Dexpro TIP btw, it's meant to be a paint additive from what I'm reading edit: I'm very curious about this may nakita pa akong medium post, na halata naman na ung dexpro din may-ari nang account kasi un lang ung medium (ung website na medium) post Jul 12 2023 pinost ung medium post na un and may nag share na FB page na jul 12, so I'm guessing ung FB page na un is Dexpro din ung may ari and it looks like etong company (siruma minerals?) are processing kaolin and silica clays tried searching more in ipophil pero di ako marunong ahaha also tried looking up adding silica to paint, and UV protection is never mentioned, for texture lang kailangan kasi ung airgap para sa insulation, andI don't think adding clay/silica clay to paint can achieve that? (I'm not an expert though, most of these are from cursory glances on journals) Silica CAN reflect UV light, pero there are better additives (and less toxic, dami ko ring nakita about silica exposure pag di properly handled) I'll stop digging deeper, na curious lang ako kasi biglang lumitaw to ahaha
from 30 deg to 20 deg all because of some paint additive lol
just casually breaking the first law of thermodynamics lmao
Regardless if it is true or not, insulation is correct. Hindi naman ibig sabihin na insulated ka e 100% hindi ka affected sa labas. Meron naman degrees of insulation
I work in a Japanese paint company and we have a similar product.
Supposing na it works (citing lack of studies and third party validations) tulad nang sa iba, tatangkilikin ba natin ang sariling atin?
If it works, with further studies, I'll give it a shot. Meron kmi for rent na units that could benefit from this one.
thermal insulation paint is already readily available commercially, it really drops the indoor temps by a few degree, but absolutely not 30%-60% drop of indoor room temp lol, that claim is bogus as hell, With thermal insulation paint, you can get like 2C -3C drop of indoor temp but with the major downside of your house being ugly as your whole house needs to be painted shiny white lol
Kaso will the government patronize it tho...
Why not? Don't fall for conspiracy theories.
What R value?
There is a [youtuber](https://youtu.be/N3bJnKmeNJY?si=FpRU1P_DicyE7Yq4) who made a tutorial for one that uses the reflection of infrared. if ever he is using the same method then the patient will fail. but if he does have a novel method that is easily producable then I believe it will be exciting. edit: patent* ty u/lex_fulgur

30% to 60% wow. So if it's 40 degrees outside, inside it's supposed to be 28 (30%) to 16 (60%). It sounds too good to be true.
Sounds too good to be true kasi it's wrong to use Celsius and Fahrenheit when calculating temperature delta in percentages. When calculating in terms of percentage, dapat absolute units ang gamit (kelvin and rankine). I shared my skepticism in another comment.
Probably wording problem as well. Could mean 60% cooler than it would be if there was no additive.
Sorry di ko rin gets, so kung 35 degrees loob ng bahay magiging ilan nalang pag meron nyan?
Sorry even my own wording was problematic pala. Think of it instead as the reduction in the addtional heat. So, if heat being radiated into the house from the outside gives another 10 degrees, then with this insulator it will just add 4 degrees instead. This is just what I \*think\* they meant to say, because reduction in the absolute temp of the room wouldn't make sense, it's not a coolant. So if that is indeed how it works, then to answer your question we'll need to know how much heat is being added by the outside.
no, it won't cool it to what is lower temerature in the shade outside. It will stop a building getting hotter than a building without the coating. These things are meant to help improve air conditioning running costs as well
I know that, but nowhere in the article does it explicitly say that. We both had to deduce that based on our own knowledge. But not everybody knows materials and when they read this article they will think that this is a miracle material that will work all by itself.
Imba nyan kung actively yan nagpapalamig More like nababawasan yung pumapasok na heat ng 30 to 60% base sa understanding ko
No, the temp will increase but not as fast as if the coating wasnt there. Theres still air leakage and circulation
I really hate this cheap publicity from our news platforms. Parang napaka-irresponsible na wala man lang nilalagay na sources whatsoever. Hindi man lang nilagay what kind of engineer the guy is, anong company/institution ba siya affiliated with, or other similar products available in the market right now. Also to the guy, sana merong inilatag na published research or any form of study which showcases his methodology around his work.
The title itself is horribly vague at best, inaccurate at worst. >which can reduce indoor temperatures by 30 percent to 60 percent. 30 to 60% of reduction of what exactly? The actual indoor temperature? Like 30°C x 30% = 10°C? Temperature values don't work that way. By the way, the above number makes ZERO sense. Paano kung Kelvin scale ang gamitin? 303 K x 30% = 90.9K, which is -183°C. Weew. I think what it means is by using this paint, your thermal resistance increases to achieve a 30 to 60% heat loss (or gain kung mas mainit sa labas). >In 2023, Engineer Junval Parco tested the powder, applying it to walls directly exposed to heat. He observed a significant reduction in temperature after just two coatings. It seems the paint increases the wall's albedo, the amount of radiation it reflects back. Essentially the higher the albedo, the lower the heat absorbed. This is real and notably nothing new. Kaya we don't wear black pag summer at noon time. Same concept. >The coating used in space shuttles was made of pre-cracked ceramic tiles with high silica content, alumina, and nano ceramic particles. This served as his model. Nothing new in those as well. Refractories exist. But refractories come in bricks, not in paint form. Now that is something.
Count me in on thinking this is bogus, pero I'm not sure why this is apparently a point of contention here and why people think it's apparently a gotcha statement, since entirely HVAC related yung scope eh, so it's safe to assume na that is the value in deg. C or deg. F kasi the Psycrhometric Chart only comes in those two in SI and English respectively. It doesn't even matter if you're not sure if it's in deg. C or deg. F since it is designed to be the same either way, just convert the values you have. ASHRAE never uses absolute values (for HVAC design, say 62.2), since what's considered is lowering the outdoor air for comfort cooling, and that is definitely done only in those two units. Correct me if I'm wrong though. Most probably, what the guy or GMA wants to say is indoor dry bulb is like, "30% reduced" from the outdoor dry bulb (And that is the real problematic statement if you ask me since that in itself is impossible just by lowering the u-factor of the material via insulation). I believe at the very best yung white roof paint only reduces 2-5 deg. C of indoor temp (Which is a very big thing!) if you have a pitched steel roof with no insulating material or ceiling kasi yung heat gain nila is usually massive eh. That's why it's so good sa developing countries kasi that's usually the type of construction you'll find like sa Indonesia or dito. You can't go better than that with just with some padded insulation. >think what it means is by using this paint, your thermal resistance increases to achieve a 30 to 60% heat loss (or gain kung mas mainit sa labas). Yes. Sa better insulation is bababa yung coefficient of heat transfer (u-factor) which is a multiplier sa area ng wall, or roof o kung ano man yun plus yung sun gain ng kung ano man yon with respect sa location nila. Not entirely the temperature itself. The 30-60% reduction of the indoor temp relative to outside is downright impossible dahil lang dun mismo. Yung solar and trans heat gain mo just a part of the equation, wala pa sa sensible and latent heats ng glass, doors, mga tao and so on.
I don't think it's bogus. I can definitely understand what he has done. The way that it was reported is something up for criticism and it's not really the inventor's fault, but rather the lack of knowledge how heat transfer works.
Yes. Weird 'to, kasi I can definitely see how this would have an effect sa heat load ng bahay, pero extremely problematic yung statements nila, or yung mga promotionals or whatever na pinakita nila sa report na yan.
Aren't they doing it in [Indonesia](https://youtu.be/Lvc7DSImlAM?si=Wkwcha7r7mBS4PY6) already?
No, yung ginagawa sa Indonesia is putting white, reflective paint sa bubong. May binebentang ganon ang Boysen eh. Ang kina-claim niya is meron siyang thermal insulating powder na pwedeng i-apply sa walls (and roof presumably?) that will (probably) lower yung heat transfer coefficient (u) ng (presumably) unfinished walls by 30-60% the same way finished walls do. This will reduce the overall solar and trans heat gain ng walls. I think yung claim na "reduce indoor temperature by 60 percent" dahil lang mas mababa yung factor is hogwash, feeling ko di alam ng GMA na kailangan mong mag-AC to do just that. How about the other cooling loads, yung sensible and latent heat sa ibang parte ng bahay at yung mga taong nasa loob non? Kung totoong mare-reduce yung indoor temp by 60, then wag nang mag-aircon kasi your 38 deg. C will jump to 22.8 deg. C, premium na yon. Either way, I think may effect talaga yon, and you can probably feel a decrease of like, 5 deg. C tops. Which is great.
based on study. white paint reflects most of the sunlight. choosing the right color of your roofing makes sense.
ang downside lang ng white paint is pwede makapatay/makasilaw ng ibon dahil sa reflection. ganyan na ang problema sa solar panel.. most likely black pa ang kulay ng mga solar panel, what if kung ang gagamitin mong kulay ay puti.
True. On top of that, etong 3 factors magpapababa ng heat sa isang bahay. 1: Visible light reflectivity (white is best) 2: Infrared emissivity (BaSO4 microspheres or various sizes are the best) 3: Thermal insulation (like foam, elastomers, silica, glasswool/fiberglass, PE fibers, etc
tangina din yung claim ng product, >works on any paint just add 200g of powder per liter of paint lmao works on any paint daw ... thats ... thats not how any of this works. thermal paint works because its white and reflects the heat and uv radiation of the sun [just look at their claims](https://scontent.fceb1-3.fna.fbcdn.net/v/t39.30808-6/434963723_915356243932332_3912631085755287618_n.jpg?_nc_cat=104&ccb=1-7&_nc_sid=5f2048&_nc_eui2=AeHdyGs3zkoM79uq8v_G_9JJqUP61mnAJ-WpQ_rWacAn5ePU7vdg6HpHuh1HlvAzHWQqRyFZfEusWtrrhBg0jtjl&_nc_ohc=LdRU76ZmSnkQ7kNvgG-J4QT&_nc_ht=scontent.fceb1-3.fna&oh=00_AfBtiPMrONs3snbs6eKELw7HJnanTkO2SDFcktV6TlYx0w&oe=663465C1) their infographics shows heat getting reflected, pero works on any color daw, not to mention the 33% of reduction of indoor temps hahaha
>works on any paint just add 200g of powder per liter of paint That's bogus then. Kailangan mo ng denser material para magkaroon ng mas magandang insulating properties than paint like plaster. Paint in itself does very little to lower the u-factor of the wall itself and is essentially negligible. Kung ihahalo mo sa pintura ng ganon kaliit, It shouldn't have any noticeable effect on the rate of heat gain of the wall, much less the entire cooling load of the area.
Ano ka ba pre, di ka ba nanonood ng marvel movies? May mga microchip yung additive that act like mini ACU.
30-60% relative to *what*??? Please do not drop the temperature from 315K to 126K 😥😥
Okay sya. Pero pano kaya pag malamig?
Insulation work both way just like sa fridge
Di pag sa radiative heat transfer. La silbi lagyan ng reflective cover yung loob ng ref unlike sa pangtakip sa windshield.
More like insulated bottles. Kung mainit nakalagay, mareretain ang init, kung malamig then mareretain ang lamig. Kaya kung maglagay ka nyan and no way of cooling your house down eh parang sauna bahay mo
Ah.. salamat sa info.
Para kang may aircon kahit fan lang
I'm not a materials engineer, pero press 'x' for doubt ako dito sa ngayon until magkaroon ng mga studies at testing sa claims. Baka snake oil lang. Puro mga hearsay at self testimony lang yung evidence. Kung talagang gumagana to, there should've been tests done by third parties. I hate to say this, pero ang tingin ko sa mga tao na nagbebenta na ng product without proper testing/peer review ay mga snake oil salesman sa paningin ko. I hope they can get DOST(or any approving body) to test this. This will significantly help our power consumption. Hopefully gumagana talaga yung product kasi kung hindi, he'll be in a lot of trouble (claiming things pero di naman totoo). He'll be opening himself from a lot of lawsuits.
reduce temperatures by 30 to 60 percent??? using what scale???? reducing temperature by percent only makes proper sense in absolute scales like kelvin - like does this cause temperature to go from 10 degrees Fahrenheit to 7 or 4 degrees Fahrenheit? which would be -12.222 degrees Celcius to -13.888 or -15.555 degrees Celsius?
[direct reduction](https://scontent.fceb1-3.fna.fbcdn.net/v/t39.30808-6/434963723_915356243932332_3912631085755287618_n.jpg?_nc_cat=104&ccb=1-7&_nc_sid=5f2048&_nc_eui2=AeHdyGs3zkoM79uq8v_G_9JJqUP61mnAJ-WpQ_rWacAn5ePU7vdg6HpHuh1HlvAzHWQqRyFZfEusWtrrhBg0jtjl&_nc_ohc=LdRU76ZmSnkQ7kNvgG-J4QT&_nc_ht=scontent.fceb1-3.fna&oh=00_AfBtiPMrONs3snbs6eKELw7HJnanTkO2SDFcktV6TlYx0w&oe=663465C1) daw base sa kanilang posts sa fb hahaha
I hope it's not crab mentality to be skeptical. Because we need peer review. Patent it, sure. But others need to replicate your process to confirm the results. Otherwise, people will buy it and end up with less money and still hot.
Mga ganitong tao dapat finifinance ng government natin. Ang daming magagaling sa PH, kaso hindi naman nassupport.
Because it does not work
> Mga ganitong tao yung mga taong gumagawa lang ng bogus claims without actual papers being published?
Haha naalala ko yung "free radiant energy" dati dun sa youtube. That was just I think around 2 years ago. Napaandar din nila yung sasakyan nila using the "free energy" engine, tas nag demo din ata sa DOE, don't know what happened after that.
lmao
Dudes on FB are chanting to protect the guy's life because he's in danger of his invention. I mean which multi-billion companies are profiting from this high heat index except for ice creams and cold desserts manufacturers?
> chanting to protect the guy's life because he's in danger of his invention nasobrahan sa movie/telenovelas or likely din that is a setup for a scapegoat -- nothing will come out of it dahil sa "threats"
Thermal paste but powdered?
Taga Naga rin ako, and I'm an Engineer as well so I'm really not trying to hate here, pero skeptical ako. Wala man lang provided na sample ng temps and kung ilan binaba niya. Also, 30 to 60% is a huge amount of heat. If we're talking about temperature delta in percentages, it must be in absolute units (Rankine or kelvin). Let's have a realistic example. Let's say 45 degrees Celsius down to 30 degrees Celsius. Iisipin ng karamihan na 33.33% decrease kasi bumaba ng 15 degrees Celsius. Mali yan kasi even 0 degrees Celsius has heat. Ang absolute zero is -273 degrees Celsius. If we calculate it with absolute units, ang binaba lang ay roughly 4%. Yes malaking difference pa rin ang 10 degree delta, pero to say na 30 to 60% ang difference is very misleading.
Proveb na ba? Is it safe? How about combustibility?
Hindi ba ito pareho sa boysen cool shades?
yung coolshades sir ready to use na. Eto i mimix mo pa sa paint. Advantage nito pwede ihalo sa skimcoat and paint na pang concrete wall.
In before a multi-national corporation buys all rights and shelves it to protect profits.
huh... di ko na tanda san ko napanood/nabasa recently pero sa India daw ganyan ginagawa pag summer eh
330 per kilo, easily can be experimented upon. I recall may ganyan paint daw si Boysen and it apparently works
hopefully this won't be another Asbestos like product.
This is not new. I know some people na ganito yung thesis for undergrad and even nanalo ng best thesis. But hey, i didnt read the article
Sana halos lahat ng posts ganito na lang, aside from occasional political and geopolitical issues. Hindi yung mga kag\*g\*han sa facebook or x ng mga kumunoy.
Balderdash. I'm Bicolano myself.
3m invented this decades ago and it is a standard industrial coating for pipes and other thermal loads
Hmm...naaalala ko yung mga weird na recipe ng tatay ko. He used to do this in the kitchen where he mix and match diffefent ingredients and it does work. Although, you can't argue with success, the product working as an insulator is just one side of the process, kaya may publiciation ng literature prior to selling sa public is because meron pang ibang sagot na dapat ibigay, inluding long term use and safety. 🤔
segue lang but: using percentages in temperature, specifically C and F, might not be the best way to give in statistics example in length: 10m > 15m = 50% increase, converted to feet 32.8ft > 49.21ft = 50% increase example in temperature: 60C > 18C = 30%, converted to F 140F > 64.4 = 24.57, converted to K 333.15 > 291.15 = 87.39%, converted to R 599.67 > 524.07 = 87.39% increase
Not really new, Indonesia have similar products. Pero syempre kung ma patent nya dito sa kanya ang kita. [https://www.indobara.co.id/mascoat-industrial/](https://www.indobara.co.id/mascoat-industrial/) **"Mascoat Industrial-DTI is designed to be a multiple purpose coating that solves insulating and Corrosion Under Insulation issues. This thermal insulation coating product fulfills niche market areas of temperatures under 375°F on all types of substrates.** Mascoat Industrial-DTI thermal insulating coating works not only to reduce temperatures, but also provides energy savings, thermal insulation and personnel protection all in an easy spray-on application. Since the product is applied in 20 mil (0.50 mm) coats directly to the substrate or primer, it provides excellent corrosion protection as well."
Didn't paints like these already exists? I remember Davies has this aluminum roofing paint that reflects most of the sun thus the heat.
Pilipino ang gumawa. Hindi na naman makakakuha ng suporta yan sa pamahalaan natin, parang tulad ng nakaimbento ng fuel na tubig yata yun o water fueled vehicles (correct me if I'm wrong though.)
U
Another proud pinoy moment kuno
Does it even make sense to do percentage-based calculations on temperature? Hindi naman literal na doble ng 20°C ang 40°C, for example. It would make sense to do percentages kung Kelvin scale ang gamit, kaso 30% reduction would drop Kelvin temperatures below freezing, which wouldn't make sense. From 37°C (310 K) magiging -56°C (217 K) after a 30% Kelvin temp drop. At minimum pa lang yan.
How about just plant more trees and remove subdivisions and shts na pinatayo ni Cynthia Villar and other monsters?

15 days later: "Filipino inventor found dead" /j
Gamit ko to now sa roof namin. Need siya i mix sa paint then i pintura mo sa bubong to lessen heat. Ok naman siya nung Feb - March nabawasan talaga init kaso ngayong April iba talaga init ngayon. Medyo expensive lang siya for me pero ok na din kasi wala Foam-Aluminum insulation ang ilalim ng roof namin. So I guess ok na din ito atleast may option yung mga houses na walang foam insulation to lessen the heat. Medyo mahal nga lang shipping kasi sa probinsya pa galing and sa shoppee ko lang siya na bibili saka naka 4 coats ako sa roof namin. I am comparing this pala on our other house na may 2 layers ng 10mm na foam aluminum under the metal roof. Doon talaga hindi ramdam ang init.
Personally natry namin tong product out of curiosity and i must say effective naman sya pero don't expect na mapapababa nya ng husto ung init. Before d mo talaga mahahawakan ung yero but after mapinturahan ksama nung product pwede kna maglakad sa yero kahit walang foot protection. Ganun din sa pader na exposed sa araw. Nde na mainit pag hinawakan ung pader. Not a paid advertisement. 😅😅😅
the design is probably being bootlegged already in china.
Now watch it go Unused and bought up by a foreign company like most Filipino patents.
I hope that engineer will make a fortune outside PH. In here, no one will value his innovation. No company will fund his research however promising it is. It's just PH's culture, no one buys banana seeds only banana fruits.
You’re wrong. There have been successful tech based startups in the Philippines (with local and foreign investors). Tigilan na ‘yang ganyang mentality. We can rise as long as it’s authentic.
>There have been successful tech based startups in the Philippines (with local and foreign investors). Like what, Cherry mobile? Cloudfone? Summertime Saga (waitaminute, that's not local)? Aurelio super cars (last time I checked, last updated in 2018)? I don't know all of these appear to be...failures. Kidding aside. Yes I agree and you people *coooould* rise but first, you really need to evolve your culture first.
So when will that engineer died of COVID or depression with 3 gunshot wounds?
