Business DailyThe cooling conundrumGlobal warming means the world will need a lot more air conditioning - but will the AC just make global warming even worse?The Middle East already experiences peak temperatures over 50C, as the Kuwaiti social media influencer Ascia Alshammiri testifies. And things are only set to get worse. Ed Butler speaks to climatologist George Zittis, who says urban temperatures could hit 60C later this century, which combined with rising humidity could render some places uninhabitable.In any case, it means a boom for the air conditioning industry. But AC itself is a major source...2022-01-2818 min

Dans cette conférence époustouflante, le physicien Aaswath Raman détaille la technologie qu'il développe pour exploiter le « refroidissement du ciel nocturne » – un phénomène naturel où la lumière infrarouge s'échappe de la terre et se dirige vers l'espace, transportant la chaleur avec elle – ce qui pourrait réduire considérablement l'énergie utilisée par nos systèmes de refroidissement. Apprenez-en davantage sur la façon dont cette approche pourrait nous conduire vers un avenir où nous puisons intelligemment dans l'énergie de l'univ2018-06-0113 minTEDTalks 과학과 의료우주 공간의 차가운 특성을 재생가능한 자원으로 바꾸는 방법 | 애스워스 라만(Aaswath Raman)지구상 건물들의 냉방을 위해 차갑고 어두운 우주 공간을 이용할 수 있다면 어떻게 될까요? 물리학자 애스워스 라만은 적외선이 지구에서 우주로 빠져나가면서 열기를 빼앗아가는 자연 현상인 "복사냉각"을 이용해 냉방 시스템에 사용되는 에너지를 극적으로 줄이는 기술을 발명하고 있습니다. 그의 강연을 통해 이 기술로 미래에는 어떻게 우주의 에너지를 현명하게 이용할 수 있을지 알아보세요.2018-06-0113 minTED Talks Science and MedicineHow we can turn the cold of outer space into a renewable resource | Aaswath RamanWhat if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" -- a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it -- which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.2018-06-0113 minTEDTalks Wissenschaft und MedizinWie man die Kälte des Weltraums als erneuerbare Ressource nutzen kann | Aaswath RamanWas wäre, wenn wir die Kälte des Weltraums zur Kühlung von Gebäuden auf der Erde nutzen könnten? In diesem atemberaubenden Vortrag erläutert der Physiker Aaswath Raman die von ihm entwickelte Technologie, um die "Nachthimmel-Kühlung" -- ein Naturphänomen, bei dem Infrarotstrahlung die Erde Richtung Weltraum verlässt und so Wärme abtransportiert -- nutzbar zu machen, wodurch der Energiebedarf unserer Kühlsysteme dramatisch sinken würde. Erfahren Sie mehr darüber, wie dieser Ansatz in eine Zukunft weist, in der wir die Energie des Universums geschickt anzapfen.2018-06-0113 minTEDTalks Ciência e MedicinaComo podemos converter o frio do espaço em um recurso renovável | Aaswath RamanE se fosse possível usar a fria escuridão do espaço para resfriar as construções na Terra? Nesta palesta surpreendente, o físico Aaswath Raman detalha a tecnologia que ele está desenvolvendo para coletar o "resfriamento radiante noturno", um fenômeno natural em que a luz infravermelha escapa da Terra para o espaço levando consigo o calor. Esse fenômeno poderia reduzir drasticamente a energia utilizada pelos sistemas de resfriamento.

Naked Scientists, In Short Special Editions PodcastA cooling layer for solar cellsSolar power is growing in popularity around the world, with huge solar farms springing up all over the place. Obviously, solar panels need as much sunlight as possible, but this also means that they heat up, limiting their efficiency at converting sunlight into electricity. This conundrum may now be solved, thanks to a clever coating designed by Aaswath Raman and his colleagues at Stanford University. Like this podcast?
