Phrases such as 'needs to be commercialized yesterday' and 'this is really cool' showcase a sense of urgency and interest, while others speculate on potential applications, pointing to a recognition of the relevance and impact of this technology.

AgreementModerate agreement

Most discussions express a favorable viewpoint towards the principles outlined in the publication, indicating general alignment with the technology's potential benefits.

InterestHigh interest

Participants demonstrate strong curiosity about the topic, highlighting the relevance of energy-efficient cooling technologies in the context of increasing global temperatures.

EngagementModerate engagement

While there are some deeper discussions on practical implications, many posts simply express enthusiasm without delving deeply into technical details.

ImpactHigh impact

Overall, there is a shared belief that this research could significantly influence future cooling technologies and environmental practices.

Abstract in brief

  • Researchers developed polyethylene aerogel (PEA) with high solar reflectance and low thermal conductivity to enhance daytime radiative cooling.
  • The PEA achieved 92.2% solar reflectance and 79.9% infrared transmittance, addressing issues of solar absorption and thermal insulation.
  • Experimental results showed that the PEA can provide cooling power of 96 W/m² and maintain temperatures up to 13°C below ambient conditions, improving passive cooling for air conditioning and refrigeration.

@SueDinNY The physics of radiation absorption & energy transfer between molecules including the influence of gas pressure,is the same in both cases We know EXACTLY which light frequencies are & which are not absorbed by co2 If we didn't,we could not build co2 lasers https://t.co/RwWUfBlBxc

@shafercw @MattSliva @WTRF7News It's ok Big Fossil Sheeple, next you will call co2 plant food. Anything can be a pollutant if there's too much of it in the wrong place. A lung full of water & of 70% co2 would be equally deadly. As is the wrong amount of insulin injected https://t.co/RwWUfBlBxc

@gbmillion @NotiviviendaSLP @ClareSaxon The ground is what retains heat overnight & emits long wave infrared radiation which CO2 absorbs, which is why nights are warming faster. Temperature is the average kinetic energy of a substance & individual excited CO2 are rapidly vibrating. https://t.co/PVhN2GWczf
