White houses are often boring, but they might just save the planet. As USA Today reports, Purdue University researchers have developed an ultra-white paint (it just earned a Guinness World Record) that reflects 98.1 percent of solar radiation while outputting infrared heat. As this leaves the surface cooler than the environment (regular paint warms the surface), it could effectively replace air conditioning in some cases — it produces a cooling power of 10kW for a 1,000sq. ft. roof, or more than a typical house AC unit.
nite, all
My uncle, one of the thriftiest people on earth in his day, had a house built in Florida some 30 years or so ago. 2 things I recall that he did that helped undoubtedly with cooling costs - white roof and larger overhangs. That kept the high sun out of the windows, and reflected a good deal of the sun's heat back skyward, which decreased the house's heat load. I have no idea how much of a difference it made, but I bet it was helpful.
That’s a solution that has about 10X problems associated with it, among them the local air/vegetation/ground surface temperatures and people and animals eyes…
How about tin foil? It'll keep out the 5G, too.
