Solar Air Conditioning

This video starts with a visual montage of the sheer number of air conditioners used on our street in Cairo, Egypt, describing them as energy parasites that actually increase the heat of the surrounding air. It then shows the vacuum tube heat pipe solar absorption cooling air conditioning system installed by solar engineer Les Hamasaki at the Debs Park Audubon Environmental Center in Los Angeles. Les Hamasaki describes the 10-ton solar chiller and we conclude with a note about how solar chillers not only eliminate the need for air conditioners, but the need for entire power plants. They also produce hot water and can be used for sterilizing and desalinating contaminated water. As we say in the video, solar air conditioners "USE THE SUN'S LIGHT TO DEFEAT THE SUN'S HEAT!" Thus, the hotter it gets outside, the cooler it gets inside!

if homes had solar reflective paint on the exterior for starters - a lot of heat would not enter in the first place

@tlaroche38 Yes, a solar air-conditioner takes a lot more room. It, however is far less costly in the long run. I am not referring to this machine but to other designs that I know of. A good one that will do a whole house takes about 3 feet by 10 feet of roof space. It doesn't weigh much so the roof does not have to be extra strong to hold it or anything. The largest part is the solar collector that dries the desiccant.

The solar air conditioner still takes up lots more room than any other air conditioners, and it alone can't eliminate the need for power plants. Until every other electric device comes up with some means of powering itself, then that thing is utterly pointless. Ill stick with my R407C air conditioners thank you, which you could fit about 100 into the size of that stupid thing. And in the winter, how does it heat? In the UK it would be useless.

@jwalker477 Yes, there are lots of people who delude them selves about such things. It isn't special to the "tree huggers". People do it all the time. They think that the next barrel of oil will appear by magic or that the "power plant" makes energy or one of a great many things like that. The best thing that those of us who know about engineering can to is to try to supply the facts and hope that they sink into the discussion.

@knowledgemonger Seriously, most of these tree huggers who pride themselves on being "enlightened" (or whatever) don't understand a damn thing about engineering or how the world works. There's a video here on youtube where these hippies laud a hydrogen vehicle whose fuel is produced by electrolysis of water, but they're under the impression that you just pour a bottle of water into the fuel tank and the car will run lol

"thousands of watts per hour" tank the credibility of the whole thing. The music also distracts. The overwrought voice over and wild claims really lowers the odds that anyone will believe you. Even though the technology can be done, by time you started talking about the actual machine, I had already decided that it was likely nonsense. The talk about the machine did not get me back to the point of believing you. I suggest you make a new version of this video.

@Pneuma001 yeah, that was exactly what I was stating, and probably you can get free energy from it if you add some magnets... k, trying to get serious now... it DOES substracts energy from the universe, specifically from the Sun, where a normal AC substracts it from the power surge, that's the only difference... the Universe still balanced, but one system uses energy that probably needed coal to be produced and the other uses the Sun, that will warm the Earth anyways...

[Pneuma001]

@eavaria So you're actually arguing with the scientific law of the conservation of energy?! Are you saying that this solar air conditioning unit actually subtracts energy from the universe?

This video does such a bad job of describing any of this technology that I can't tell you where exactly the energy is going.
