HI Geoff;

I did a system in Oklahoma that had an LP powered 3 ton Air conditioner. 
As I recall, the blowers and pumps still took almost 2000 watts, so it 
wasn't a complete solution. Then to make matters worse they had a huge 
bank of glass facing west. I did some heat calculations and it looked 
like you'd need the whole 3 tons just to hold the temp steady against 
the solar gain. They were complaining the system couldn't cool the house 
down in a few hours on a 100 degree day.
I think combinations of all of you all's cooling ideas will be the ticket:
- limit solar gain
- live with higher temps and humidities
- use fans & dehumidifiers
- use swamp coolers if the humidty will allow
- take advantage of night time cooling, and thermal mass
- use ground source heat pumps
- use high efficiency dual compressor AC units.

I guess I get to enjoy Taos right now; we hit low 90s and 40% humidity 
in day, but its going into the high 40s at night. Just crack a window 
and let the adobe do the rest.....(but I feel for you, I used to live in 
Austin, Tx with no AC)
