Barium sulfate (BaSO4) is another material that have 98% reflectivity between 250 to 2500nm. It is cheap to manufacture an simple to obtain. According to Perdue University researcher coating 1000 sq. ft roof give 10 kW of cooling capacity. Industry grade Barium Sulfate cost ~$0.60 per kg. You probably could make your own paint at home by mixing barium sulfate with exterior primer and used that as paint.

So a 95% reduction in electric bill is claimed from a system which saves 60-80% on cooling cost? Doesn't add up.

Two Bit da Vinci, this video blows my mind! I’m going to have to watch it a few more times to fully absorb the science and I am INTRIGUED ☮️ Thanks for creating & sharing this

I think aiming the radiative panels north and solar pv panels south would be a good way to use both on the same roof.

Here’s a thought. The sky cool panels could be installed on the non-southern facing parts of the roof which are less efficient at creating solar powered electricity. So you would have radiative cooling, which doesn’t have to be aimed at the sun, on the areas of your roof with less potential for solar power generation. Of course the ideal solution would also involve increasing the albedo or heat reflectivity of your roof along with solar power generation in the solar panels on the sun optimized areas of your roof and the sky cool panels on the rest.

I’m curious how this scales? I’m thinking of industrial chiller plants. Those things are major energy consumers.

When my last ac quit in a heatwave, I got one without a heat pump. It seems way more efficient now.

Don't send it to space! Use it as a directed energy weapon!

Good information in this video. This looks like a great technology. A lot of numbers were shown except the current cost to purchase/install this system.

Well, I guess, we should add these to all the glaciers, and ice shelf. this would reduce their temperature on the surface, and take the excess heat. Or pair them with the solar panels, have them cool the panels during the day increase their efficiency, and during the night, they cool the liquid medium even further .

This was a really neat review, I've never seen tech like this. Thanks again Ricky!

Just changing from medium brown asphaltic roof shingles to white asphaltic roof shingles on my previous house saved 40% on electricity in summer. Reflect rather than absorb. Insulate directly under the roofing and you reduce heat trapping in the attic. This is usually easy and inexpensive. The spray foam insulation directly applied to a high reflection color metal roof is extremely good at reducing cooling costs. It minimizes the masses heated by sunlight absorbtion.

8:42 There is no heat pump in this picture. It is an evaporative cooler (AKA a "swamp cooler"). Coincidentally, evaporative coolers also are most effective in the same climates that SkyCool's are. A SkyCool system could be used as a precooler on an evaporative cooler making it more effective over greater range of climactic conditions than an evaporative cooler alone while still being much more energy efficient than compressor-based ACs.

In Brazil pay the power bill is now prohibitive

About time someone put this concept to use, thank you.

This is amazing and it is not a joke. I would combine this system with the water collection from air where you combine warm humid air with a cold surface so it gets condensed.

This is theoretically possible, Infrared LEDs do this in very small quantities. I didn't think the material science was far enough along for large scale applications. Overall sounds promising but I would definitely want to see some more third party reviews. Also, cloud cover shouldn't effect cooling ability, just equivalent emissions, so... some concern on the language there.

Optimize system life-cycle costs with PV (for other electrical loads) on south and Sky Cool on north facing roof exposures.

Great explanation of the panels & coating. Thanks!
