Bringing the chill of the cosmos to a warming planet Scientists are tapping into a law of physics to create cooling systems that work without special fuel or electricity By Sarah Kaplan OCTOBER 7, 2020 Long ago, in lands that were always warm, people got ice from the heavens. At sunset, they poured water into shallow earthen pits or ceramic trays insulated with reeds. All through the night the water would radiate its heat into the chilly void of space. By morning, it turned to ice — even though the air temperature never dropped below freezing. This wasn’t magic; it was science. For centuries, desert dwellers in North Africa, India and Iran tapped into a law of physics called radiative cooling. All objects — people, plants, buildings, planets — give off heat in waves of invisible light. On a clear, starry night, that radiation can rise through the atmosphere until it escapes Earth entirely. Coldness, which is really the absence of heat, is created through this invisible connection to the cosmos. The world now cools off with the help of more than 3.5 billion refrigerators and air conditioners, a number that is quickly growing. But those appliances are also a major source of greenhouse gas emissions. In seeking relief from the heat, humans are making the globe even hotter, compounding the demand for cooling. To break that cycle, University of California at Los Angeles materials scientist Aaswath Raman wants to turn ancient technology into a 21st-century tool. Working with colleagues, he has developed a thin, mirror-like film engineered to maximize radiative cooling on a molecular level. The film sends heat into space while absorbing almost no radiation, lowering the temperature of objects by more than 10 degrees, even in the midday sun. It can help cool pipes and panels — like a booster rocket for refrigerators and cooling systems. Incorporated into buildings, it may even replace air conditioning. And it requires no electricity, no special fuel — just a clear day and a view of the sky. “It sounds improbable,” Raman acknowledged. “But the science is real.” Generations after people learned to make ice in the desert, he hopes that same science can help us survive in a rapidly warming world. https://www.washingtonpost.com/climate-solutions/2020/10/07/radiative-cooling-climate-change/?arc404=true http://www.aaswathraman.com/

I am genuinely intrigued as to how this is going to be spun by MAGA pro-lifers... The mental gymnastics coming up should be interesting....

Mayor Pete throwing some fire early today: Good on him!

First "Top 20" rankings released today....... https://www.sportsnet.ca/cfl/article/iowa-offensive-lineman-tops-cfls-first-scouting-bureaus-top-prospects-list/ TORONTO — Alaric Jackson, an offensive lineman at the University of Iowa, has the No. 1 spot in the first edition of the CFL scouting bureau’s top-20 prospects for the 2021 draft. The six-foot-six, 315-pound Jackson is a native of Windsor, Ont. He’s entering his senior season at Iowa, which kicks off its ’20 campaign Oct. 24 at Purdue. Jackson started 10 of Iowa’s 13 games last season at left tackle. He redshirted in 2016 but has started for the Hawkeyes since 2017. The CFL released its top-20 list Thursday. Calgary’s Amen Ogbongbemiga, a senior linebacker at Oklahoma State University, was the second-ranked prospect. The six-foot-one, 235-pound Ogbongbemiga has registered a team-high 22 tackles (12 solo) and 1.5 sacks in three games for the No.10 Cowboys (3-0). Ogbongbemiga had 100 tackles last season and was named the Cowboys’ top defensive player. Vancouver’s Terrell Jana, a receiver at Virginia (1-1), is at No. 3. The six-foot-one, 200-pound Jana has nine catches for 84 yards and a TD this season after registering 74 receptions for 886 yards and three touchdowns in 2019. Josh Palmer of Brampton, Ont., a receiver at Tennessee, holds down the No. 4 spot. The six-foot-two, 210-pound senior has 10 receptions for 156 yards and two TDs for the Volunteers (2-0). At No. 5 is Ottawa’s Liam Dobson, a six-foot-three, 340-pound senior offensive lineman at Maine. Dobson’s ranking comes despite the Bears not starting their season until the spring due to the COVID-19 pandemic. Dobson enjoyed a stellar ’19 campaign, earning All-CAA first-team honours and being voted as Maine’s top offensive lineman. He was the school’s highest-graded offensive lineman for every game and averaged 12 knockdowns per contest. Dobson contributed immediately upon arriving at Maine in 2017, appearing in six contests (one start) as a freshman. He became a full-time starter in 2018. The remainder of the top-10 includes, in order, includes: New Mexico State offensive lineman Sage Doxtater (Welland, Ont.); North Carolina State defensive lineman Daniel Joseph (Toronto); North Carolina defensive back Patrice Rene (Ottawa); Maine linebacker Deshawn Stevens (Toronto); and West Virginia defensive back Alonzo Addae (Pickering, Ont.). The first 10 selections were all from NCAA programs, not a surprise given U Sports cancelled its 2020 season due to the novel coronavirus outbreak. The top Canadian collegian was Montreal offensive lineman Pier-Olivier Lestage, of Saint-Eustache, Que., at No. 11. The other U Sports selections included Calgary Dinos offensive lineman Logan Bandy of Calgary (No. 12), Saskatchewan defensive back Nelson Lokombo of Abbotsford, B.C. (No. 14), British Columbia linebacker Ben Hladik of Vernon, B.C., (No. 16), Calgary linebacker Grant McDonald of Tsawwassen, B.C. (No. 19) and U.B.C. linebacker Nick Cross of Regina (No. 20). Defensive back Deane Leonard, who helped Calgary win the Vanier Cup last year before transferring to Ole Miss for 2020, was ranked. No. 13.

What a waste of money.

So..... an American Stephen Harper?

He lies just as much as Trump, shows his hypocrisies just as much as Trump, but does it just more calmly than Trump's bluster.

Huh, words from the potus matter... who knew? I remember when he said that and thought... "yeah, some yahoo is going to take that and run with it..." The next plot i think will originate from "stand down and standby." Words from the most powerful office in the world matter....

11 broadcasts. 6 different games in total, 5 of them repeated. Not sure who gets it worse - Montreal fans who get to see 4 different losses played 7 times over, or B.C. and Ottawa fans who apparently don’t have CFL teams.

The fly came to the right place if he’s looking for siht...

REGENERON! I always look forward to project Lincoln stuff...

We need more mental health supports, including addiction counselling. These should be human rights. Everyone is entitled to a happy, healthy life and a basic income would go a long way to providing that. We have the wealth but do we have the political desire to do it?

What, no hydroxychloroquine, UV therapy, or bleach injections...?

Things that happen..

A week ago, he told his armed supporter nazi gangs to go to polling places and "observe" voting. Of course, that's totally illegal but everyone has forgotten because at the same time, he also told the the Nazi Proud Boys to stand by and wait for further direction. That distracted everyone but not the nazi gangs. There will be violence and intimidation at the polls. We saw it two years ago and now it's going to be worse.

They just can't help themselves. I was like WOW this actually seems like they're getting their **** together....buuut inevitability TSN/CFL show they're still exactly who we thought they were. lol. It's comical at this point.

Just as well, IMO. Might as well enjoy the outdoors this weekend; it's supposed to be pretty nice.

Notable..

They would have to. Vegas is actually in a pretty bad situation right now. If they retain 2.0 and cost us 4.5 I would do that in a heartbeat. Send off some B level prospect in return. One year to bridge the gap for Perfetti.

Debate grades: Harris C+ Pence D Fly A+

Well, there was one, albeit very tiny, fan: Or perhaps the fly was just attracted to all the BS being spewed.

Cool, maybe a new way to approach homelessness

Trump now telling everyone that has Covid they will get the same medicine he received for free, good luck with that, in the next couple of weeks he will be begging for vote's.

Smarmy flyhead that he is.

Please do. Can you make sure you tell him there's a bit of a rush on this request.

I'll call Chevy.

Turris has attitude problems...no thanks to that guy. Buff is done.

Kind of getting tired of this BS from the Roussin: Sorry, but the best way to stop the spread in personal care homes is for the Gov't to get off their butts and do something before it becomes a problem. They continue to fail to do that.

Hillary!!

These Trade tree videos are always fascinating to me! Love them.

It's getting to the point the person im borrowing netflix from is gonna ask me to pay up. But until that day comes when he finds out im okay.

Also yesterday I noticed that SNL took off the geo block for alot of their videos on youtube (I don't know if it's just for the election though) many classic sketches are now viewable, including the tv funhouses....this is one of my favourites. This was made at the height of Disney's straight to dvd boom Now if only Conan would take the geofence off his

I worry that he'll die before he gets to prison. I hope that's not the case.

Science.

If this was a drinking game you would be dead with all the "thank you vice president" , again another debate that will change nobodies mind

The moderator is doing a pathetic job in stopping the yapping of Pence. He’s lost and it’s half way through. I thought he would do better. Pence has got nothing to work with because he has to repeat lies. But he’s lost. He’s ffiggin rude. I hope Pence has eaten before, because Kamala is eating his lunch. Pence going off topic and small time bullying isn’t helping his cause. He surely does not respect the moderator...at all. Is it because she’s a woman?

Who was the poor soul who had to cake on the make up and then shellac him

YIKES!

I wish they would have shown either the 2005 game where Milt had 4 catches, 4TDs, 200+ yards or the 2010 Casey Printers meltdown.
