If that's 99.6% reflective, how is this new paint the whitest ever at only 98%?
Could be the spectrum that its tested under. Maybe the 99.6% is visible light and the 98% is all energy from sun. If that's the case, the 98% is much more impressive.
I bet this would look fantastic mixed with some vantablack, for the greyest grey achievable.
The next step is using the combination in e-ink fashion, so that you can smoothly regulate the thermal profile as needed.
Honey, it’s going to be -27°C (-16.6°F) tomorrow, can you turn the reflectivity to 0% after brewing the coffee?
"We did a very rough calculation," said Prof Ruan. "And we estimate we would only need to paint 1% of the Earth's surface with this paint - perhaps an area where no people live that is covered in rocks - and that could help fight the climate change trend." LMAO me I love living in the future. This sentence could’ve been lifted from the Hitchiker’s Guide to the Galaxy.

I think part of they problem is that whoever invented this paint is going to want a massive premium for its sale. So it'll get some niche industry use until the patent expires and people start painting their desert roofs with it, or whatever else. Apply to this virtually every technical innovation that is iterative. Fundamental breakthroughs allow for a shakeup of the incumbents, iterative ones don't, due to the arch…
This is a very insightful comment. Perhaps you are aware, but some economists have designed mechanisms to "split the difference" in a manner similar to what you describe: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2744810
In the apartment I rent there's a huge 1.5x1.5m ceiling window for letting the sun in. In addition to huge 2m-high windows. The number of buildings not suitable for the present-day climate is astonishing.

This is nothing new. You are just now hearing more about it because of how journalism is being done online. There have always been lots of revolutionary things happening in labs. They are rarely ever practical, or if they are it will take decades to bring to market. How many dozens of new battery techs are announced as being "better than lithium ion" only to disappear once everyone realized how impractical they are.…
Your point clearly has merit in many cases, but paint seems almost the epitome of practicality. Assuming that it could be mass producible at a price similar to premium house paints I can't see the problem in bringing this to market. And from the article: > In the US, New York has recently coated more than 10 million sq ft of rooftops white. The state of California has already updated building codes to promote cool ro…
If you wanted to wait for this specific product, that's fine, but that's almost like waiting for 26% efficient solar panels instead of ~23% we already have (even though most production panels are 18% - 22%)...
And actually this is also one of those things that also helps beat Tesla Solar roof - get a white paint - THEN add bifacial solar panels. So the Tesla roof panels is actually worse for your overall cooling than regular panels now.

Wouldn't the reflectivity degrade almost immediately, as dust landed on said painted surface?

There are a lot of practicality/implementation concerns to paint other than what color it is. Just as many if not more than there are for battery technologies. Does the paint stick to the surface you want to paint, how is it applied, what is the coverage, is it durable, does it repel contaminants, can it withstand the environmental conditions, is it chemically compatible with the surface, it is chemically a concern f…
