Researchers at Columbia Engineering have invented a high-performance exterior PDRC [passive daytime radiative cooling] polymer coating with nano-to-microscale air voids that acts as a spontaneous air cooler and can be fabricated, dyed, and applied like paint on rooftops, buildings, water tanks, vehicles, even spacecraft -- anything that can be painted. They used a solution-based phase-inversion technique that gives the polymer a porous foam-like structure. The air voids in the porous polymer scatter and reflect sunlight, due to the difference in the refractive index between the air voids and the surrounding polymer. The polymer turns white and thus avoids solar heating, while its intrinsic emittance causes it to efficiently lose heat to the sky.

Very easy and you don't have to wait for this one. You go to your hardware store. And you ask for the Solar Reflective Paint Additive. Trust me, you'll save BIG on your AC with that one. And it works with every color of paint -- even black!!!!

I hope there's a special place in hell for you. There aren't any beachfront properties or golf courses where you're going, you sick bastard. What good will solar reflective paint do you in the eternal fires of damnation? How's that going to save you when they throw you in the lake of fire? I hope it's teeming with sharks, just for shitstains like you.

That one's between me and God. And I think God likes me A LOT. He made me VERY SMART. Put me in a fantastic Family. In the best Country. And I've made a lot of very very smart decisions. But I've also had tremendous luck. God gave me a beautiful Brain and beautiful Luck. Like nobody else has. I thank Him for that. I'm always thanking Him. And I've done a lot for God -- more than anybody else has ever done. Especially since I went into politics. I picked Mike Pence, very strong God person. Religious. I moved my Embassy to Jerusalem -- fulfilling a Prophecy. Making the Bible come true. And I nominated Brett K., very devout Catholic, for SC. Very strong moves for God. If you were God you'd be very happy right now. And you could say, my agenda is God's agenda. Many people are saying that!!!

So let me make a wild guess here. Bill Spaulding is a golfing pal and/or you own a bunch of RPM stock.

I didn't say Rust-Oleum. We love Rust-Oleum. But there are many brands. 3M, so many. We love ENVIRONMENTAL. And we've gotten many awards for environmental. More than anybody.

Trust me, I've gotten TOO MANY to list. I'm known as America's Environmental Hero. Read Ed Russo's book!! amazon.com/Donald-J-Trump-Environmental-Hero/dp/1535456868 [amazon.com]
