Certainly, if it is an "efficiency" measure, it is a very expensive alternative to efficiency measures that might achieve more benefit for less investment. When factoring the economics of savings an the miriad of other available measures and technologies, geo-exchange may be quite inefficient. I will trust that the alternatives have been well vetted for the particular case, but will nonetheless suggest caution in categorically accepting geo-thermal exchange heat pump systems as efficient.

If the ground temp in summer is 60-70 at that depth, rather than the 50 or so that you see up north, then you don't have as much of a cooling sink as you might in other areas. I hope that McD's considers this demonstration and also how it might work in other geographic areas.
