21 Jul 10 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!

    Get a aluminum an put it on your window reflects the heat. Thats what my grandmother would do when it was summer time.

    and don’t forget, it can also dry beans, lol.

    I agree with wolfpack1960 this is innovative but the cost is ridiculous!

    Nuclear Power all the way just build the plants in the center of major cities and dump the spent nuclear rods in Afghanistan

    good luck proping 20 tons of metal on your 12 story apartment window,its what the electric companys dont whant you to know,yea were all saved so innovative this gigantic block of steel for one house,i know the idea is there but still ,its not that advanced yet

    The manufacturer of the 10 ton unit is Japanese company Yazaki, not Mizaki.

    @Terryblount – Can you really say that this guy is an “idiot”? He is obviously quite intelligent. It’s true that tapping into the ground is an easier way to gain access to cooler temperatures, BUT the unit in this video can supply cold air, hot water for showers, dishwashers and clothes washers, and can also supply a clean source of drinking water by way of distillation. It’s NOT just an A/C unit, although that is the main selling feature.

    Not only are solar pannels expensive ( require 30 years to pay back) but they require as much energy to be manufactured as the energy that they produce during their life. Second, nuclear is by far the best fuel available to us at the moment. We’ve got the infrastructure and the know how. Nuclear power plants are compact and only require a few acres to be built and can connect to the power grid easily, Solar power is the exact opposite. I don’t see why you stated that nuclear plants are BAD.

    @skinEpete The idea looks good but i have to visit this place to make sure it cools enough and then see if it warms enough during the winter. Another issue is the price…This installation may cost between half to a million bucks to install. I bet.

    @wolfpack1960 lol i bet you would…mabye if you accepted your own quazi religious tendencies you may not be frightened by others. 😛

    I invented a breakthrough energy source which violates the law of energy conservation. I have a PROOF that there are electrodynamic phenomena which violate the law of conservation of energy. I am looking for $30 000 fora prototype and for $3M for patents. Making a 15 kW generator will cost $1200 in mass production, value of the energy produced yearly about $10 000.

    AC units still use CFCs?

  13. |

    last part, shut the fuck up

    Pretty cool, though you come off as a total quack with that cultish introduction.

  15. |

    I want one, But first I’ll need to build another house to put this monstrosity in.

  16. |

    what a LOSER!!!!!!!!!!!!!!!!
    he doesn’t know what he is talking about!!!!!!!!
    whatta loser, srly!!
    he uses lame arguements from the 1950’ies….

    All the A/C does is move heat. It doesn’t ADD heat to out side. Heat gets into a home, the A/C only moves heat from inside to out side. Learn how any a/c works. LOL

  18. |

    OMG EVVVVVIIILLL corporations building power plants! They must be stopped!

  19. |

    unfortunate down side is the cost, caused by corporate greed.

    @wolfpack1960 : my 3 energy save ac units jump my electric bill only $40 a month for the 5 months of hottest part of the year….even if summer lasted 12 months, 235k would last me 489 years. The 3 energy save ac units cost me $400 ($150 for each of 2, and 1 smaller one for $100…all at walmart).

    I still don’t see how heat+cold=colder? This video is baffling thermodynamically (and proprietary reasons are probably keeping a lid on the ACTUAL of what’s going on).

    Inverter heat pumps are super-efficient. Redo all the figures-only using Daikin’s super inverter heat pump. I bet it will be just as efficient as your eco-solar crud! I have to admit, solar power is one googoplex times better than wind power.

    ROFL look at that huge beast
    It’s funny how it mainly shows air conditioners from apartment buildings hanging out windows.
    Could you imagine that gigantic tub hanging out a window? Not practical at all.

  23. |

    Holy Christ this guy is dumb as fuck, he thinks ACs heat the world around him. That’s hilarious!

  24. |

    BULL SHIT

    @goyby

    The only issue in this situation is that with this system they are using evacuated tube solar collectors, a solar thermal application, which is actually completely different from PV in that they basically super heat water (or glycol solution) by collecting light and turning it into heat. No electricity needed, or even generated. Also, in this case they need the water super hot to air condition, so the ambient temp being higher helps the unit operate much more efficiently.
