Whiteface?

[ElNono]

Scientists created the world's whitest paint. It could eliminate the need for air conditioning.

The whitest paint in the world has been created in a lab at Purdue University, a paint so white that it could eventually reduce or even eliminate the need for air conditioning, scientists say.

The paint has now made it into the Guinness World Records book as the whitest ever made.

So why did the scientists create such a paint? It turns out that breaking a world record wasn't the goal of the researchers: Curbing global warming was.

“When we started this project about seven years ago, we had saving energy and fighting climate change in mind,” said Xiulin Ruan, a professor of mechanical engineering at Purdue, in a statement.

The idea was to make a paint that would reflect sunlight away from a building, researchers said.

Making this paint really reflective, however, also made it really white, according to Purdue University. The paint reflects 98.1% of solar radiation while also emitting infrared heat. Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power.

Using this new paint to cover a roof area of about 1,000 square feet could result in a cooling power of 10 kilowatts. “That’s more powerful than the air conditioners used by most houses,” Ruan said.

Typical commercial white paint gets warmer rather than cooler. Paints on the market that are designed to reject heat reflect only 80% to 90% of sunlight and can’t make surfaces cooler than their surroundings.

Two features make this paint ultra-white: a very high concentration of a chemical compound called barium sulfate – also used in photo paper and cosmetics – and different particle sizes of barium sulfate in the paint, scientists at Purdue said.

Researchers at Purdue have partnered with a company to put this ultra-white paint on the market, according to a news release.

Trump says orange is the new white.

Poor Uncle Larry is a step behind. :lol

Good joke, but that's pretty amazing. Trumptards are gonna start painting their roofs black soon.

They might be able to afford using incandescent lightbulbs again...

It would not eliminate the need for air conditioning

Karrin would definitely make sure he doubles down on air conditioners just for an "that'll show 'em." :lol Drunk faggot

Hell no!

These MAGAtard MoFo’s are still crying about candles and whale oil lamps!

They are stuck in pre-1861 ideology America.

"Paint emits more heat than it absorbs"

Think about the physics of that statement.

[ElNono]

"Paint emits more heat than it absorbs"

Think about the physics of that statement.

I think what they mean by that is that it that is highly reflective, not that the paint is generating heat all by itself.

Trumptards lining up against the color white now.

Yup, article states paint is highly reflective.

CCs confusing comment comes from taking out of context: “Because the paint absorbs less heat from the sun than it emits, a surface coated with this paint is cooled below the surrounding temperature without consuming power.”

gonna be worthless up north though, anything you make up in ac you lose in heating

[DarrinS]

There are three modes of heat transfer. This paint addresses one.

Probably would lower your energy bill.

If any of this was true it would be hotter at night because it's black outside. How about that?

"Paint emits more heat than it absorbs"

Think about the physics of that statement.

It probably means to say that some paint absorbs light energy and then re emits the energy as light and heat.
Light and heat energy are different wavelengths or frequencies. If you theoretically could have paint that absorbs light and heat energy, and then re emits that energy mostly as light... It would be fkn bright around that space for us. But the material would then not transfer heat energy to the inside of the house.

Black usually refers to the absence of energy in science.

Almost thought this was a legit post. This invention seems like would save me money. Then..... a Larry Elder reference. Isn't he the same color as you bro? Black on black crime... why?

Sorry, the statement still defies physics. Reflecting radiant heat does not "cool" a surface. if the ambient air is 100 degrees the surface will not be less than 100 degrees because of convection heat transfer. Yes, if it reflects 100% of the radiant heat it will still be cooler than a surface that doesn't reflect radiant heat but it can't possibly cool the structure.

But it could prevent the structure from becoming hot in the 1st place, depending on how well insulated the structure was. But I've seen multiple articles with conflicting claims, some say it reduces the need for AC and some say it prevents it. Anything that reduces absorbed heat would be a plus (in the summer).

Of course as soon as some dust settles on the surfaces, the show is over. Then you have direct thermal transfer.

It was a joke.

However as the paint becomes more and more white, the surrounding colors will appear oppressed.

According to the researchers’ cost estimates, this paint would be both cheaper to produce than its commercial alternative and could save about a dollar per day that would have been spent on air conditioning for a one-story house of approximately 1,076 square feet.

grains of salt of course in terms of the above is Purdue's PR dept so they also can gloss over the science and downsides while hyping benefits

But thermal imaging doesn't measure the air temp. The surrounding masses that would be hotter would likely be hotter than the air temp, especially pavement or roofing materials.

[CosmicCowboy]

I keep an infrared thermometer on my desk to check employees temps. Pointing it at my dark desk consistently gives a reading of around 6 degrees F higher than a white sheet of paper that has been sitting on the same desktop for days. I'm pretty confident if I used an actual thermometer they would be the same temperature.

[Allan Rowe vs Wade]

Would your infrared thermometer measure your darker skinned employees as being warmer than your lighter skinned employees?
