icon_snowSome time ago I read that the earth temperature 80 cm deep is a steady 8 degrees centigrade. First thought: can we use this to cool air in the Summer? Trying to find more info I realized that there’s a LOT of challenges.

  • What pipe length/diameter
  • How to keep the air moving and how fast?
  • What pipe material? (Aluminium is not strong and corrodes? Plastic? Metal?)
  • How to handle condensation water? (Mold)
