Todd:
In my present life but in a dimension far, far ago, we were  investigating 
the use of such "technology," which had been referred to by the  builders in 
Arizona and So Cal at that time as "Cool Tubes."  It consisted  of 6" irrigation 
tubing buried between four and six feet deep radiating from the  home.  If I 
remember correctly, you needed at least an acre to consider  doing it.  
I remember being told that the warm humid air would enter the nice cool  
tube(s) and finally enter the home at 65F.....dehumidified!  What a  wonderful 
thing... but, the humidity had not vanished.  It had  condensed inside the 
tube(s) causing mildew etc.  The other issues were  varmints and insects.  Fire ants 
too.  I think the 3' culvert with an  air entry six feet above ground with 
steel wire mesh and an armed sentry  posted (to stop the human varmints) has got 
to be the best way to go.
 
Not even worth two cents.

In a  previous live, when I was a engineer for a (so called) "public" 
radio  station, one of the remote broadcast mountain tops was cooled with 
the  earth. There was about 100' of ~3'diameter cement culverts stacked 
end to  end, buried about 4 feet below the ground. On the intake end was 
hardware  cloth screening. In the transmitter building a large squirrel 
cage fan  sucked cool air through this tube. It worked very well and 
successfully  mitigated the inefficient tube transmitter's heat production.

Another  example is at the hydro plant I work part time which is mostly  
underground. The highest summer temperature runs about 60 degrees (when  
it is 90 out) and the coldest winter temperature runs about 50 degrees  
(when it is 25 out). This is with considerable air flowing through the  
dam adits (out in the winter and in, in the summer). Harvesting the  
moderating temperatures of the earth seems to be a reasonable solution  
to space conditioning.
