NightHawkInLight's super CaCO₃ micro-sphere pigment recipe:
Sodium Carbonate (washing soda) ......... 20g dissolved in 200 mL water
Calcium Chloride (painter's desiccant) ... 10g dissolved in 100 mL water
Citric Acid (used for canning) .................. 3g dissolved in 30 mL water
1. Combine Calcium Chloride and Citric Acid solutions into one container.
2. Adjust the temperature of the liquids to be between 10-20°C (50-70°F).
3. Pour Calcium Chloride/Citric Acid solution into mixer and begin stirring.
4. Pour the Sodium Carbonate solution into the mixer and begin a timer.
5. Allow solution to mix for 1 minute.
6. Turn off mixer and pour the liquid into a separate container.
7. Wash the mixer with vinegar and water to prepare for the next batch.
***Make 3 total batches following steps 1-7, each time allowing the solution to mix for 1
minute. To save time you can make large quantities of the starting solutions all at once,
chill all of it to 10-20°C, and then measure out enough for individual batches by volume
just prior to mixing.
8. Make a fourth batch, mixing for an increased time of 5 minutes.
***Optional: Make a fifth batch at 1/3 scale, mixing for an increased time of 8-10 minutes.
9. Allow 20-60 minutes for the pigment to settle out of all batches.
10. Pour the water off the top of the settled pigment and refill containers with water.
11. Repeat settling and pouring off water 1-2 more times.
12. Cut a rectangular opening in the bottom of a disposable bread tin.
13. Line the tin with paper towel and a sheet of white printer paper.
14. Pour the pigment solutions into the tin, using the paper as a filter.
15. Pour extra distilled water over the pigment to wash it.
16. Once filtered, place the whole tin into an oven to dry at 100°C (212°F).
17. Collect pigment, breaking up clumps in a blender if needed.

I can confidently say that this is the best research process I have ever seen demonstrated on KZfaq. Presuming you have robust and reproducible data of all the observations you present in this video, this is easily a publishable project and I think it would benefit A LOT of people if you were to pursue publishing this work. There are a lot of people in my profession who wouldn't be inclined to follow the science presented in a KZfaq video, but would confidently follow the exact same science if it appeared in peer-reviewed publication. I don't think they're correct in that perspective, but I know that bias exists. Anyway, please consider publishing this work, and if you wanted or needed any input to help pursue that I would be more than happy to offer any assistance I can. ABSOLUTELY EXCELLENT WORK!

Have you considered (or tried) using a clear acrylic paint as your binder/resin? You may lose the scattering effect of the water inclusions, but you may end up with a coating that has some environmental durability. To test, just put some of your powder into some polyacrylic paint (Minwax makes one) and test rest them side by side in your box. The other advantage is that a paint based solution would be applied using a roller.

My company is in R&D for sky cooling liquid applied acrylic roof coating. We are using a crosslinking acrylic that "mends" together between coats to create a solid, durable membrane. Given that this recipe is out now..I guess it doesn't matter to keep it a secret anymore lol. I will make a new video with results of small scale tests. We currently have capacity to produce 30000 square feet of 60mil thickness of liquid applied membrane. It can be sprayed with a standard paint pump, or rolled on with 1-1/2" nap. @Nighthawkinlight thanks for this amazing contribution. This will not only reduce heat waste, but also reduce consumption of electricity for air conditioning. My hat is off to you!

UPDATE: Our test results were better than other coatings in the market, but only by a fraction of a percent! As we added more powder to the ratio, the resulting membrane developed microfractures, some of which went all the way through. So it was a no-go. We are now developing a prefinished roof panel system instead. This takes out all the guesswork and human error that occurs while spraying or rolling it out as well. It will take some time to recover from the losses incurred from the coating system tests. In short, we are giving a customer another new roof.. We will be putting together a panel coater conveyor system complete with heated curing. There are many hoops to jump through for metal paneling to be approved by the various testing organizations, but I am going to be optimistic. We have learned that using very thin coats and a more rigid acrylic base gives the sky cooling results, but it is not as durable. (pressure washer with brine added to the soap dispenser to simulate the expensive salt water test) We will likely provide a variety of sky cooling panels that range in warranty length and, inversely, sky cooling effectiveness. All this to say results will be coming in a few months more.

Those article fees are ridiculous and anyone doing educational stuff like this should not have to pay them out of pocket! Also, like a lot of others said, this is really impressive work.

Your multiple rinse steps may actually shrink the size of your microspheres a bit. Nanoparticles have a very large surface area so, even though CaCO3 is pretty insoluble some it will dissolve in the rinse water. I discovered this was true when I tried making magnesium fluoride nanoparticles (as a polishing agent). Multiple wash cycles eventually caused the MgF2 to totally disappear! Using LeChatelier's Principle, I found that adding a very small amount of a water-soluble magnesium salt prevented this. You also might be able to use this "problem" to your advantage if your smallest particles aren't quite small enough.

@joelmanthis9523 3 ай бұрын
Holy crap, this is genius. Just off the top of my head I feel like the most important parameters to test are to find a way to determine how much (if any) the Water temperature, Duration of each wash cycle and the nanoparticles size will contribute to how much degradation (shrinking) of the spheres occurs. Once a consistent method of testing these parameters is developed and employed, this can be applied with a large array of applications where density, temperature and likewise even pressure (such as hydrostatic pressure in any type of stratified fluid) are key principles to how efficient said application can be. Like using Aqua Regia for dissolving Gold.

My folks live out in the sticks in Central Texas, no river and no wells. They have a rain catchment system but there’s been no rain so they’ve had to truck in water. What they do have is humidity. They put a condensation recovery system on their AC and get a good 3-5 gallons a day off the AC for their 150 sq ft cabin. My Dad and I are trying to figure out how to use these panels as condensate catchers to farm water from the air. Right outta Tattooine :D We’re also going to cover their water tanks in this stuff and see how it holds up to the weather. The tanks aren’t shaped in a way that allows for the film shield, but right now the dark green tanks heat the water so hot we can’t bathe the baby in it. Just getting it down to ambient would be great. BTW I knocked together a spreadsheet that gives you volume and price predictions based on how many square feet you want. It’s tuned to the local stores but should be easy to modify. Let me know and I’ll send you a Google doc link.

I've said before that developing this into a quality coating material should be a government initiative and the product should be sold at scaled prices to an individuals income level with limits to allow enough paint per person to use for personal use. This technology clearly has the capability to effect our national electric consumption for cooling costs measurably across the sun belt for a large portion of the year and if leveraged into removable panels, could impact even more northern areas for the Summer months. I think we are fast reaching the point that everyone should be contacting their government representatives to make this happen.

I worked in the coating industry as a formulator for about 10 years. For application you can potentially look into wire bar applicators to help apply an even surface. Application also depends on if the paint has a low enough viscosity and a low enough surface tension to be able to self level. You could also look into addition of a wetting agent which would likely be some sort of surfactant. Ideally this coating could be made much much thinner in which case you need to ensure an even dispersion of the particles without aglomeration. I loved this video and the level of instruction and detail!

Recommendation for paint/coating application: Attach two parallel guide rails to your canvas, place a dollop of your coating at one end, and use a squeegee perpendicular to the guide rails, wiping down to spread the coating evenly across the rest of the canvas.

It might be possible to have a solder mask cut (probably in a diamond grid pattern) so you could apply it the same way as a pcb gets pasted. You'd probably need a more viscous coating for it to work though. Spread it on with a stainless scraper, and remove the mask. The fluid should spread out a bit after its removed, and gravity should flatten it out and fill in the missing spots. You could also play around with the thickness of the stainless mask too.

For your comments about using citric acid and it not being picky about water quality afterwards, I'll add that in soapmaking, citric acid gets used commonly and it performs "water softening" in the bar. When mixed with the NaOH used in soapmaking, sodium citrate is made in-situ, and keeps sodium soaps (i.e. sodium + fatty acid) in solution, vs them reacting with calcium and magnesium in the tap water, making calcium or magnesium soaps that are less soluble and leave soap scum, and the suds of the soap are less sensitive to water hardness (to a point, everything has its limits)

I'm in Las Vegas during the height of summer monsoon season so every degree of difference can save someone's life out here. I have some notes: -Without a stir-bar, it took a really long time to dissolve the acrylic. I had wondered why the paint was sepparated and thin. -A painter's knife can apply the paint fantastically -The smaller sizes of nanoparticles are difficult to sepparate out and I think I must have mistaken a lot of them for wastewater as they didn't sepparate out after days. -I used a pie tin instead of a bread tin because I'm cheap, it did not work at all.

When watching the “paint” application methods at the end of the video, the first thing that came to mind was my cordless caulking gun. The Milwaukee cordless caulking gun I own will put down a full tube of caulk in 20-30 seconds on the highest setting. You just need a refillable tube for the gun, and you have an easy on the hands applicator. I’ve broken both my wrists, and squeezing the paint from a tube for any extended period of time is painful, hence the cordless caulking gun. Since the gun only pushes a plunger for you when the trigger is squeezed, you could probably use one of those giant syringes, and whatever sized tip you could come up with to attach to the end, like the wide one. Not sure if someone has posted this idea previously, but if not, it’s something to consider for application to large surfaces.

There are plenty of differently sized nozzles for paint guns. I just came back from a low rider show and some of the flake used in the paint jobs has to be a good amount larger diameter than the microspheres he’s using in the process. Also. If the paint is self-leveling to a degree, why not just use a roller to apply it to larger surfaces?

The answer I came up with is that if you replace one large sphere with an equivalent spatial extent of small spheres, you've introduced coverage gaps inside what was previously covered by a single sphere. Really interesting!

You are such an inspiration man your videos have helped me find purpose in a dark place and are still helping keep me excited and inventing in a much brighter one. Thank you so much night hawk in light! I'll send you a video of my next prototype and I hope you know how much what you do helps people learn and feel alive and empowered with knowledge. Love and respect and gratitude to you brother. You've been inspiring and helping me for a long time and I'm glad to be able to thank you now.

This video as well as the video you made before are both so awesome. Thank you for not rushing the videos and taking the time to explain things so that those of us that are not as well educated as yourself can understand the basics of what is happening and even understand why. I really enjoyed watching. ❤❤❤❤❤
