Geothermal Air Conditioning... Old Testament Style!

I recently got a request to discuss Geothermal energy, and I will but first I want to discuss the oldest form of Geothermal use that is still in existence: Geothermal air conditioning.

Records and evidence of civilizations living in hot areas, such as Persia and Africa, have been using Geothermal Cooling in their dwellings dating back to 2500 BC.  That tells us that even back then, green energy existed.  The sad part is, people who live in those same regions are using the exact same method of cooling today, yet we can't seem to figure this out.
The way this is done is actually very simple, they built a pipe, 10" in diameter out of ceramic into their wall near the base, and it turned  downward, until it was four to 10 feet in the ground, then it turned outward, went straight away from the dwelling for 20 to 50 feet, depending in wealth of the person involved. it then turned a 90 degree turn  traveled 10 feet, turned another 90 degrees and returned back into the house, only it would travel the full length up the wall and would exit near the ceiling.  What this did was caused a circulation of air, that radiated the hot air out of the top of the house, only to radiate and be cooled by the cooler ground temperatures, and return back into the house around 70-75 degrees.
See, the ground maintains a constant temperature, whether its cold or hot outside, at a pretty steady 65 degrees Fahrenheit. and its because of this we use geothermal heating and cooling currently for both heating and cooling our homes, and heating and cooling our water, and providing electricity by using variable temperatures to create a flow or "current" to create energy.  The point here is that we can still use this same technique today.  Ceramic pipes are use for drainage mostly all over the world, but if your building a house, you can still opt to plan for this method of cooling with decent planning.
Now, while I know this doesn't really benefit you as a whole, the point was to help you understand how and why geothermal works on a basic level, so you can think about how it could be implemented in your future life.  In my next post, ill go over some low cost geothermal products that you can use on a low budget, and how doing so can profit you!  Stay tuned!

I think there was a lot of ancient technology we've lost today.

As someone who absolutely hates hot summers, I think I will put this to good use.

It's amazing how smart the "ancients" were.

me too, to save from electricity, I will just turn on my split system air conditioner every warm days, but since the weather is very cool this days, I just shut it off.
