Reply to comment by einarfridgeirs 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
Because most of these "successful" scientific results never see the light of day in actual products. They're just novel lab discoveries. Great that they're being done. But doesn't mean anything in terms of changing the future.

In laymen terms: We already use AC(which requires energy and creates additional heat) to pump the heat back outside anyway so it's more efficient to have a glass that doesn't let the heat in to begin with.
