Paint that keeps a surface below room temperature
It seems to me a most interesting development. According to information published in the journal Cell Reports Physical Science at the end of last October, scientists (Purdue University of Indiana) have developed a paint that could have industrial uses at competitive prices and that would keep the surfaces painted with it below the ambient temperature, even in the case of being under direct sunlight.
We must take into account that one of the relevant energy consumption is due to the cooling of environments. If in any area its exterior is painted with a paint that reduces the temperature of that surface to some degree with respect to that of the exterior, the cooling needs of that area would decrease, and therefore the energy consumption would decrease. With the savings that all that can entail.
So I like the idea.
As I have commented more than once in this Blog, technological developments are carried out at ever greater speeds and new possibilities for practical applications are continually appearing, although this is not always the case. But in this case its application seems quite feasible.
In the previous photo you can see a “P” painted with the special paint on a surface, and that its temperature is lower than that of the environment of the rest of the surface.
And in the photo below how the temperature of the surface under test was done and requested.
In the test they carried out, during the day the temperature of the painted “P” was 1.7 degrees lower than the rest of the surface, and at night the difference reached almost 10ºC, taking the measurements with an infrared camera .
This paint does not have metallic components and therefore can have a wide spectrum of possible industrial applications.
They still have to carry out more resistance tests over time, to ensure that it can have an adequate useful life, and reconfirm that the costs are in the order of the current market.
If that is so, you have a chance to get a good deal, and I wish them all the best.
