I live in Zone 3-5ish where it snows a bunch in the winter and has 100 degree days in the summer. I built a 29' diameter Geodesic Dome that will soon be 3-4' deep in the earth. Now I am thinking I can have ice stored (In a rubber pond liner with a roof and insulation to keep frozen throughout the summer) above the dome elevation to cool in the summer ( Maybe using a subterranean heating and cooling type setup, with 55 gal blue plastic barrel on top of the ice with the piping going from the barrel to the dome where there would be another barrel, a fan would move the cold air?). Also, I am hoping to heat with a rocket mass heater and a makeshift geothermal type heating, with the ground. Would this work as I have it drawn out? (Scale is inaccurate as of now) Thanks!

Not sure how you are planning to store the ice, or move the colder temp into the dome, but I don't think you would need to bother with it.  I would just use earth tubes like the ones you show going downhill.  If you keep that angle and open windows near the top of the dome, the 45-55 degree cool air will be pulled thru passively on warm days.

I would like to see the dome if you have pictures, in particular the material you used to cover the triangles, and how you sealed it to prevent leaks.

Thanks ,Todd! ( I am new to Permies and not sure I am responding in the correct fashion) I responded to your ice storage question with a simple edit (on pond liner with a roof and insulation) I wasn't sure if convection would draw down the cold air naturally or not. I am not well educated on physics and thermodynamics... yet. There are pictures of the dome at www.sacredacres.info or follow sacred acres on instagram/facebook. As of now, the triangles are covered with a thick fire/tear/water proof vinyl and sealed with caulk and rubber paint. This summer I will be using wood, plastic, and earth as the new cover.
