If you had solid state fan such as an ion fan (Web search under "solid state fan") Here's the Thorrn Micro Technologies site link(link not included).

And you had solid state cooling such as the a Bismuth telluride thermo couple, which utilizes the thermo electric effect.Then if you attached a solar panel to those air conditioners you would have infinite cold air production.

This is the very best air conditioner that is possible with the current laws of physics. Because this is solid state and will never break down and can be made to any temperature by stacking various numbers of plates together. But it does have the one draw back of not being the most efficient form of cooling. Which is not a draw back if you attach a big enough solar panel to it. The most energy efficient form being the regular compressed freon version.

The following quoted from wikipedia under "thermoelectric cooling":

Thermoelectric junctions are generally only around 5–10% as efficient as the ideal refrigerator (Carnot cycle), compared with 40–60% achieved by conventional compression cycle systems (reverse Rankine systems like a compressor). Due to the relatively low efficiency, thermoelectric cooling is generally only used in environments where the solid state nature (no moving parts, maintenance-free) outweighs pure efficiency.

But what I think about this is that I guess I just like the solid state nature of thermoelectric even if they use more energy. So as long as you have a large enough solar panel then you won't have to worry about the energy usage, which doesn't cost much anyway. But as solar panels get cheaper from mass production this will be even more viable than it is now. And you also never have to recharge it with freon or have to worry about finding the hole that the freon is leaking from(note: they don't use freon anymore because it's a CFC). And it makes absolutely no noise, which by the way anybody would appreciate having a more quiet house. Any rich person would prefer this technology because of it being so user friendly, and energy expenditure is meaningless to rich people.Also it can be tuned to the temperature that you want most by only having a potentiometer(also called a variable resistor) and it has to be the right sized potentiometer to never be able to burn out the thermoelectric cooling plate. So you need the thermo electric module's specs for this reason.And if you can find lots of cheap cooling plates, all you have to do is stack them for a compounded cooler end plate, with only the need for one ion fan, and maybe a filter for a dusty house. And less demand would be put on each individual plate, when combined. So never a chance of over loading and burning out one.Web search the phrase "Thermoelectric cooler" for products that you can buy, The most common being an electric camping cooler. But be sure to only buy a product that comes with specs, so that you know all of the things that you can and cannot do with the device for maximum performance, without the device ever being able to burn out.But for nighttime use there needs to be a battery energy storage system for excess energy stored during the day. The best battery would be an ultra capacitor which companies may be releasing to mass market soon, if the technical aspects are overcome.The reason I'm sharing this idea is because it's not patentable it's only marketable, but I just want one some day and will probably build one myself one day.
