Reply to comment by thehourglasses in Researchers designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. This cooler may lead to an annual energy saving of up to 86.3 MJ/m² or 24 kWh/m² in hot climates by mossadnik
Also the cost to apply it, how durable it is, etc.
I could easily see a coating that works great but turns to tinting after a couple of years and is impossible to remove.
Or it takes specialized training and equipment to apply like repainting a car does, so even if the raw material is cheap it becomes a big expense and hassle to do it.
