Really the only way to cool better effectively is to design better buildings, use polyurethane second dome skin with some cooling vents, and maybe even building underground, natures best insulator. Anytime there's some kind of disaster that requires a building to be rebuild, it's a crime not to design it for long life and ultra efficiency second time around.

Video Quote:("Today's air conditioning and refrigeration systems essentially follow the same principal, that have been around for about a hundred years.") Well so what? the wheel has been around for a hell of a lot longer and we still use it. Just because an idea or method is old doesn't mean it's obsolete. Video Quote:("Air conditioning may actually become one of our largest source of greenhouse gas emissions, later this century.") Wrong, air conditioning systems don't produce green house gases. The refrigerant is "contained" where it is simply recirculated. Asawath Raman starts this whole thing out on a false premise. If he has an alternative cooling system then fine. But don't present it by misrepresenting current methods.

You know instead of using the reflective sheets you can color your roof white to keep it cool.

Ohhhh evaporative coolers. Drying the air before cooling it. Nothing new.

It's a swamp cooler with an A/C unit in front of it. Fun fact: A/C's job is to reduce *humidity*, and it does this by lowering *temperature* - not the other way around. This is because air's capacity for water reduces with temperature. Technology Connections has a few great videos about refrigerators & A/C units (same idea), and swamp coolers.

Seemed like they were focusing more on residential. I'd like to see how this impacts commercial buildings. How much more efficient is this than a cooling tower/air handler system?

hello there! :D

Fantastic. We've now invented swamp coolers and mirrors. I can hardly wait until these are available to the public!

Air conditioners don't release the chemicals they have and radiators do not use "the cold of space" they can be pointed anywhere, just that they will warm the place that they point at.

How it works: the panels convert heat into a specific spectrum of infrared light that is able to pass through air more efficiently than any other wavelength. So they are hyper effecient at using invisible light emissions to cool below ambient temperature.

I love people who try and help the earth, thank you.

AC cooling is a closed [sealed] system. The fluid used for heat transfer is recycled for years. My AC is powered by solar panels. Researching cleaner ways is a good idea. If your AC is leaking you should get that fixed.

OH Air conditioning?! HA I thought you meant Alternating Current!

AC refrigerant, mainly R410a doesn’t leak out of AC units unless there is some sort of problem, you guys made it seem like they are all constantly venting into the air...

What is this? Sticking a mirror on a roof is innovative? Other is an evaporative cooler which exists; but faces challenges when air humidity is high.

What about lake water cooling like many big buildings use in Toronto? Not everywhere with sweltering summers also have a giantic cool great lake or ocean but for those of us that are that lucky it is a fab and underused option.

It is indeed unfortunate that Bloomberg does not provide proper linkages or credits. Aaswath Raman along with colleagues first published this around 2013, and Stanford applied for patents in 2018. I am sure after Stanford fully vetted it, then applied for patents five years later. Search and find his articles for each of You to understand the details as each of You need or want (google scholar). The film would appear to be a very nice refinement from the original articles. After reviewing several of his research papers, the remaining concerns are; achievable temperature deltas for specific humidity (appears to work better in low humidity environs!!!), the amount of heat energy which can be dissipated per square meter and whether that metric can be be improved by what process or material? Best to Aaswath and colleagues. This definitely works.

The first segment of this piece of news should be made BIGGER! You've no idea how freakin hot living in the tropics can become. Not only is it hot but its humid like f***.

That's some pretty cool tech, but that special surface, I wonder how the maintenance of it will look? What if it gets scuffed, or a bird shits on it, or it's dusty, etc. What then? From a science perspective, it sounds SUPER rad though!

2:49!!!!! okay where do you get this and could this integrated into solar panels at some point.

I mean water cooling system has been existing for a long time, the ac at HSBC hong kong uses sea water to cool their units...

High tech solutions are one way and surely attract lots of attention and investor money. But I believe that we could save lot of every and therefore avoid pollution if we would not look only into what may one day be possible but as well into what was used fur centuries. There are plenty of techniques which had been used to cool down buildings which seem to have been forgotten. Some examples: - wind towers used in Arabia - Double roofs which show the wind to go through and cool down the building - Water fountains inside the building - Small windows to the outside but larger ones to the central house patio - Insulation of walls with natural materials which can store and release some moisture and help control room moisture There are plenty more which could be used - just a question of priorities...

All window dressing. Try cooling an office tower using these highly inefficient technologies. You'll need several football fields to do it.

the cooling thing in singapore wouldn't it be damaging to computer because it only increasing humidity right?

When you want to heat something up you must use energy. It makes sense... heat is energy after all. The somewhat paradox comes with cooling technologies that actually use energy also to cool things down.

This kind of refrigeration only works in non humid environments. In humid environments, it will get even hotter due to too murky air.

Refrigerants used in heat pumps today normally do not leak, and are not a threat to our planet. If you are talking about A/C using an abundant amount of energy to transfer energy, you would be right, but thats where solar and wind energy come in.

Heat can never be "eliminated", just like how we have a law in physics that says neither matter and energy can never be destroyed... only converted. And even if waste heat is dissipated from a given system (electronic or non-electronic, biological, or purely mechanical), it will always have to go 'somewhere'....... and that 'somewhere' usually/ultimately ends up in the atmosphere.

The title is completely misleading. The act of taking energy out of the air to cool means you are conditioning air which is in fact an A/C.

Dais Analytic has been working on this for some time using nano-porous materials.

How about geothermal cooling. Save night cool in the earth or in ice for daytime use

I have been in the HVACR business for 35 years and it has frustrated me to no end these ridiculous systems that will never be residentially or commercially applicable. There are ways to easily make your current systems use up to 50% less energy but the industry doesn't push them and the average person doesn't know about them. 1. Filtered misting systems for the outdoor condensing unit that can vastly help heat rejection with minimal water usage. The head pressure is lowered and the compressor uses less energy. 2. Insulation. Insulate the attic space where the largest amount of heat gain in the summer and heat loss in the winter occurs. If you keep the heat in or out as the season dictates then you won't have to spend money moving it around. If you had a boat with a hole in it would you fix the hole or just buy a new energy efficient bilge pump. In new construction you can use foam insulation in the walls and have energy efficient doors and windows put in.

the earth atmosphere reflects heat back to earth surface, but certain heat ( in a form of very narrow band of infrared light) would escape the atmosphere and lost forever. So if you can target that specific band of light by reflecting it to the sky, you are basically sending the heat away the earth, into the space itself. And because the heat you send away are greater then the heat you receive from the ambient, that make the cooling works. There are few ways to make use of this cooling technique, you can use it to cool water, and pump the cold water to wherever need cooling. Is like how a water heater works, but the opposite.
