Hello All!
We are planning a move at some time n the future to a larger ranch, and I 
have been thinking about ways to heat/cool a large (5000 sq. ft.) horse barn 
we have and will move. The location is in the high desert of California with 
lots of wind in the afternoon and most mornings. Temps range from freezing in 
the winter to 100+ in the summer. 
These are some of my thoughts for constructing a system for at least some 
climate control. How deep into the ground would I have to lay pipe to get an 
average temp of 60 degrees or so? I have been thinking if a lay enough pipe 
deep enough (if feasable) and could cycle the water using wind (when 
available, which is most of the time) I could plumb it through a bank of old 
auto radiators with fans to move air through them for cooling in the summer 
and some heating in winter. I seem to recall a few years ago reading of a 
type of wind-turbine that was fairly easy to construct, and thought that 
would be a good way to pump the water through the system, with maybe a 2 
horsepower jetpump for the winter nights. Co-generation is also a winter 
possibility as we will probably switch the 150 HP electric irrigation pump 
for a diesel, and I have thought about the possibility of a large storage 
tank, or at least a water to water heat exchanger to store heated water for 
night use (there are only about 3 months a year when it would not be needed 
for crops). 
Of course another possibility for summer use would be to divert some of the 
pump water to the indoor cooling radiators before sending out to the 
sprinklers to be used for irrigation. 
There are several auto-bone yards around here, and I think I can make a deal 
with them for old radiators if I take what they have just before "crush" 
time, so that part of the cost should be small.
I gues my main questions are:
 1.) Does this sound do-able?
 2.) how far down would I need to place the heat exchange pipes if I went 
that route?
 3.) Does anybody know where I could find plans for a wind turbine I could 
build? 
Also, does anybody have input on ideas for a second equal sized barn? should 
I buy another steel, build from abode (warmer in winter maybe?), for build a 
straw bale barn with plywood inside walls (I have a source for free old straw 
or alafala).
