Nissan develops paint that keeps cars cool in summer heat (www.asahi.com)

Nissan Motor Co. said it has developed a new type of paint that significantly reduces the temperature inside vehicles parked in direct sunlight.

The surface of a car coated with the innovative material remains up to 12 degrees cooler than that of a vehicle with standard paint, tests showed.

The company said the coating material can help rein in the temperature rise not only on the car's body but also in the vehicle when exposed to direct sunlight.

Got in my car after work yesterday and it was 102F inside. It was awful

Lucky! I've seen 150 here in Louisiana.

And even higher when I lived in the Mojave desert. Like, if you didn't leave a window cracked there's a real chance your windshield cracks.

Must have had you wishing for a nuclear winter.

It's not so much the thermometer temp here in Louisiana. It's the 80-99% humidity. At these levels your body's main heat defense: Sweat - no longer works as it can't evaporate fast enough or at all. Then it becomes an insulator and a feedback loop of hell. Like being wrapped up in a wet electric blanket.

I live in Pa, so our weather isn't crazy hot like the south. I can't imagine the weather where you've lived. 85F is my upper limit. Anything over makes me feel like I'm going to die.

I was working outside in 96F and nearly 50% humidity within the past week.

If we continue trying to work outside during the middle of the summer day, as our summers get hotter every year, people are going to start to die.

I wonder how many it will take for America to adjust. I assume a lot more than I'm comfortable with.

I was outside in 96F yesterday herding my ducks for 10 mins and my whole night was ruined because I got so sick from the heat.

Idk how people who work outside constantly do it

Box fans and Popsicles, mostly. You get used to it. Doesn't make it any more pleasant though. I did give myself some pretty bad heat exhaustion at one point earlier this year, that hasn't happened before.

Short bursts, finding shade, and lots of water and wind (box fans, as the other fella mentioned). A good hat helps immensely. If you can duck inside someone's AC, you take the fresh air like it's the last soup you'll ever have and you suck it in.

I can remember a few summers in the desert where it would reach 130's. And as a kid back in the early 90's, we had the hole in the ozone too. No joke we had ozone warnings, and no outside recess cuz of it.

Plenty of summer nights were the temp never dropped below ~100f

Strangely, we often got winter temps below freezing.
