What 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.

  1. Not sure if this is this case or not, but if this was to be implemented at a large enough scale to generate the majority of our electricity, wouldn't this constant ejection of thermal energy into space potentially cause a global cooling effect. If it's reasonable to assume that increasing the green house effect on earth by adding green house gasses to the atmosphere has a profound effect on the earths climate, then it would also make sense to assume that bypassing the green house effect in a sense would also have a profound effect in the opposite way. From there if we were to attempt to balance the increase in CO2 to our atmosphere with the amount that we bypass the green house effect, we could potentially manage the temperature of the earth, but at the same time CO2 also has the effect of making the oceans more acidic by dissolving into the water. This could be a temporary method, but it is just as likely, if not more so, to artificially effect the climate on earth as compared to green house gasses. Just a thought.

  2. Wow!! Amazing!!…Sci-Fi sort of Tech.!!!…Probably more than the word Sci-Fi' itself !!…and the good thing about it is that it is fully able & capable to be Practically Implemented & is really a Next Generational Technology in a true sense!!!…We all would very much want that probably to be part of our daily life and of its uses of course !!,and further utilize it for many different & other purposes or other possible uses as well!!.,as many as there can be !!…..This guy or this project/concept of his really needs a full scale funding!!!,..he just actually deserves it !!……My deepest respects,gratitude & compliments !!… Excellent !!!.Really!!

  3. And when this is perfected and used everywhere we are going to have people freak out about "global cooling" and how we should not beam out into space our precious energy.

    Side note. I dont find heat an issue, but humidity seem to be the bigger problem for humans. 110F with low humidity, not a problem. 95F at high humidity , unlivable.

    What I would prefer , is that we can store the summer heat so I can keep my pool at 85F in the dead of winter. How big of a chunk of thermally isolated copper is needed for that ?

  4. I just started the video, but wouldn't the lack of matter in space prove difficulties to transfer heat into it?
    It may be "cold" but there is so little mass you have no heat sink capacity to transfer heat into it. Just like a radiator in your car requires air to run across it, you would need a similar amount of mass/air to achieve similar results. Thing is you'd need like supersonic wind to cool a radiator if you're using a parcel of "space" material.
    Ahh okay, radiating heat via IR light at a wavelength that penetrates the atmosphere. Not a bad idea.

  5. My new, electric motor technology will make these AC compressors, air conditioners, and heat pumps, 2-4 x more efficient, such that air-conditioning systems could be run directly from solar panels. Electric cars would only needing a starting battery, as long as the sun was shining, or if you had this guy's "nano-photonic" thermal electric panels to generate electricity (instead of cooling), your electric car could run directly off the electric differential between warm pavement and cold sky- REAL FREE ENERGY.

  7. This will be earths come back part one , we need to be proud today coz we have found a big come back for the earth , this is not just and idea this will completely change everything for us and also generate electricity in the night the very same we generate during days and also during the days , this will change everything as we would stop emmitting so much carbon out , buildings designed in such a way that the complete building would have a roof of this material completely covered with huge panels and cool the buildings for free and producing electricity again and again , But what about the water in the panels that will eventually evaporate how do we stop that from evaporating or can we use some kind of gels instead or try to keep the water chambers expandable so that even when they evaporate they still remain in the chamber and keeps turning into ice again and again and with emergency water intake which is precooled with electricity generated with the same panels , does that give any solution or am i right or not , but its a great search , great work brothers
