Electricity free way to cool a home?

What are things that you do? We don't have air conditioning, but do have ceiling fans which I would prefer to not use. We live in a garage and it gets HOT. Hopefully we will be insulating the ceiling soon, but I doubt that will help much with the heat...

Do you have any links or other information about this?

Unfortunately no, I don't have a link because I haven't written the article about it yet. I invented them. The idea is simple though so let me give you the short version: A lunar panel is the opposite of a solar panel. With a solar panel you capture the light of the sun and turn it into heat energy which you then pump into a storage vessel. Rewind. With a lunar panel you take the heat from a vessel and run the fluid up through the panel pointed at the darkest part of the night sky (not actually the moon) and the heat radiates away. The now cooled fluid is denser so it falls back down into the vessel (your house, concrete slab, water tank, etc) and picks up its next load of heat. Once it is warmed it rises back up through the up side of the tubing to the lunar panel where it once again releases it's load of heat. Presto: Lunar Cooling Panels. I like passive systems that use thermosiphons so it has no motor burning energy but you could build it with a motorized pump if you were upside down (e.g., you were sending the heat down into a pond or the ground.)

I worked for a solar pool heater company and they suggested doing just as Walter detailed to cool off the pool if temps got too high. Just run the panels at night-- doesn't matter if the moon hits them or not. It really works.

Exactly. The moon has nothing to do with it. I just like calling them Lunar as opposed to Solar. Technically, the darkest part of the sky would be best.

You can use pex tubes with sprincklers on the roof, one pump takes the water in a well or in a rain water collector, a timer or an appropriate thermometer drives the pump and it goes; water that has not been evaporated comes back by gutters. Now you have the biggests , the cheapest but efficient air conditioner in the neighborhood!

Dude, a swamp cooler is your best option and it does not not take a lot to run one. I lived in the high desert and in the top of the summer day I would spray my roof with water. It cooled the roof off to mitigate the heat gain. Have you thought of a tarp that is wet? Cal usually has dry wind. The effect of the evaporation will cool you off inside it. Misters too work, same principal.

Just get a cheep above ground pool and use it.

Also, you need to vent the roof heat will rise and cool drops.

we have an indoor outdoor battery thermometer that we keep an eye on..if the temps outside are cooler than the temps inside and not forcasted to drop TOO cold (like 40's or so)..we open every window in the house and let the colder air inside..then before the temps are equal inside and out, while it is still cooler outside..we close all the windows and pull the blinds if the sun is out and the forcast is for very very hot weather..thus trapping the cold air inside and keeping the warm air outside..we only pull the blinds on the sunny side of the house in order to still allow plenty of light in the north and non sunny areas..only preventing the sun from getting too hot inside.

we avoid anything that produces heat in the heat of the day here, attempting to do any laundry, run dishwasher, cook, etc..inside during hot days..we plan cold meals or cook outside on the grill.

also remember to dress in light colored clothes outside in hot weather and there is a new item for heat rashes that appears to work it is Gold bond friction stick..like a deoderant stick that you use where you get heat rashes..(which i get badly in the summer ..also get heat stroke)..i tried it and so far since i've used it, no heat rashes..woo hoo..they can be very painful.

also switch to LED lights where you can to cut back on heat..if you have fans use them only to circulate air when it isn't blowing hot air on you.

unfortunately we had to lose a huge tree in front of our house that provided shade all summer long to our home..which is gone now..so we are planting more trees..that will take a while.

you could grow vines up the outside of your house to shade the house as well..including things like green beans up string..

apologize for not taking time to read all the tips..just don't have the time right now

did you find out about the old burlap coolers?

basically a window box with burlap hanging down like a screen, and soaking up and evap'ing water. what they used to use out here in the southwest.
works best in windows the wind is blowing into, especially a high one.

seach for burlap cooler, burlap icebox , and burlap cold storage


got a solar panel?

can also build up a stack of bricks, or blocks, higher than the window opening, on the sunny side.
spray em down, inside, and out, and the air on the inside will be much cooler than the outside.
put a couple potted plants on top to help out more.

Evaprative cooler work well in dry climates. They compound the problem in high humidity areas.

Soak some thin blankets in water and hang them in front of windows/doors.

Hose off your roof to cool it off.

Hello. I have looked into such things before. Have a look at this...

http://en.wikipedia.org/wiki/Absorption_refrigerator

Particularly the part about "Water spray absorption refrigeration". I could easily see this being AC built cheap and easy. All you need is salt, water, heat, and ingenuity.

Edit: It's not unlike a "Swamp Cooler" Only these will work in wet climates where the former will not.

I had a garage that heated up to 120 degrees in the summer. I insulated the ceiling with styrofoam up against the UPPER
attic rafters. This allowed the heat to rise UP and then
OUT of the garage through a roof-turbine vent. After insulating the walls, this garage rarely went above 82 degrees
during hot summer days even with NO AIR CONDITIONER. Another method of accomplishing this is to simply paint
the roof white. I found a way to do this at a cost of less than 20 dollars. You can read about this on the
website "builditsolar.com" here is the link ..... http://www.builditsolar.com/Projects/Cooling/WhiteRoofExperiment/WhiteRoof.htm
These methods work VERY well and have minimum cost. The attached picture shows attaching styrofoam sheets
to the upper attic rafters in process (not completed).
