No I can't, but I can tell you how to install geothermal heating and A/C in your house.
Cool! ground coupled heat pumps i presume.
I did my thesis in college on refrigerant mixtures in vapor compression cycles with emphasis towards low temperature differential applications like ground coupled heat pumps. I also worked with ground coupled heat pumps on side as an assistant and pay the bills. I have also got into radiant floor heating design in the last few years as a side hobby.
