1) I'm not seeing much daylight between this 'breakthrough' and flat white, titanium dioxide-based pigments.
2) Secondly, I see no discussion of 'latent' heat, which is typically the reason behind refrigerated air conditioning.
3)' Cooling' the inside of a home can 'kill' you, if you don't 'dehumidify' the air volume ( at high dewpoints, you could produce condensation on every internal surface of the living space, triggering 'black-mold') ).
4) The temperature of a roof and it's radiative load, downwards through an attic space can have 'zero' effect on the cost of cooling.
