Cooling panel sends excess heat back into outer space (Eliminate A/C? Power companies won't like)

It’s a giant mirror.

With no fans or active circulation isn’t it going to take forever for the heat in your house to make its way to the device for subsequent re-radiation?

I think of hot summer mornings here when the rising sun is heating the east wall of the house (and we need to turn on the A/C at about 9AM). Humidity not really a problem here, though. Tends to be about 40% in an air conditioned house.

Have nothing whatsoever to do with the topic here.

Now Al Gore will have to stop galactic warming. That would be very inconvenient, indeed.

I don’t know about it being a scam - they may just be a bit naive or optimistic.

I agree with you, though, a mirror would probably reflect more than this device, including IR, however the reflected IR from the mirror would most likely get absorbed by the atmosphere, whereas they claim that their reflected IR would not.

Regardless the mirror would still cause the house to be cooler, whether it’s enough to compensate for the ambient warm air is doubtful.

Obviously anything that reduces the heat load on the house is useful (that’s why houses are insulated).

So the key question is, is this new thing better and cheaper than insulation?

Even if they get this thing to work and even if it is cheap as dirt to instal and maintain your electricity bill will not go down because the rate will rise since the utility companies still have to fire the generators and the government will tax you on the power you might have used just like the rain taxes.

Anthropogenic Space Warming?
This is not going to end well.

They aren’t very specific on how it removes the heat from the building but I am assuming that the roof load is removed and that might decrease the load on the ceiling but what do you do with the infiltration load and the loads that come from the windows, doors, walls, human activity, appliances and especially the Latent load? Do these panels send the given amount of energy back into space when the sun’s rays are shining directly down upon the panel or when the sun is at all positions during the day?

" particular infrared frequency band that will pass unattenuated through the atmosphere.."

Two problems here. 1) The band they are using, according to the chart they had (~10 microns) is the wavelength the atmosphere itself radiates. (Which is why infrared astronomers have to build high or go into space). 2) Heat flows from hot to cold, not the other way around. The way an air conditioner works is to make a hot compressed fluid. The heat of the compressed gas is hotter than outside so it can flow outside. The fluid is then allowed to expand making it cooler than ambient. The heat from indoors flows into the cool fluid.

...but it won’t make the house any cooler than the temperature of the air.

By itself, probably not. But if it can prevent the heating effect of sunlight on the roof it might moderate attic temperatures and reduce the cooling load. In sunlight with an air temp of 105 my attic might be 150 and the AC struggles. I'd love to be able to keep the attic at the ambient temperature.
