As climate change intensifies summer heat, demand is growing for technologies to cool buildings. Now, researchers report in ACS Energy Letters that they have used advanced computing technology and artificial intelligence to design a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy.

Studies have estimated that cooling accounts for about 15% of global energy consumption. That demand could be lowered with a window coating that could block the sun's ultraviolet and near-infrared light -- the parts of the solar spectrum that typically pass through glass to heat an enclosed room. Energy use could be reduced even further if the coating radiates heat from the window's surface at a wavelength that passes through the atmosphere into outer space. However, it's difficult to design materials that can meet these criteria simultaneously and can also transmit visible light, meaning they don't interfere with the view. Eungkyu Lee, Tengfei Luo and colleagues set out to design a "transparent radiative cooler" (TRC) that could do just that.

The team constructed computer models of TRCs consisting of alternating thin layers of common materials like silicon dioxide, silicon nitride, aluminum oxide or titanium dioxide on a glass base, topped with a film of polydimethylsiloxane. They optimized the type, order and combination of layers using an iterative approach guided by machine learning and quantum computing, which stores data using subatomic particles. This computing method carries out optimization faster and better than conventional computers because it can efficiently test all possible combinations in a fraction of a second. This produced a coating design that, when fabricated, beat the performance of conventionally designed TRCs in addition to one of the best commercial heat-reduction glasses on the market.

Unfortunately, there are dangers associated with stratospheric aerosol injection. This approach may reduce rainfall in some areas of the world. Loss of crops and access to fresh water due to reduced rainfall could lead to starvation and suffering. If this approach were used, it would be important to develop and implement measures to protect people and save lives and livelihoods....instead human lives being sacrificed for greed

Singly and in combination (as 'silicates'), these four earths make up just about two thirds of the earth's crust.
