Passive Cooling: Rock Wall. A Natural Thermostat: "Large rocks squeezed into together by 'wood shelves' insulate the South face of the house. The rocks absorb the heat during the day lowering the solar gain. At night the rocks give heat back into into the air as the temperature outside drops. The rock wall and the desert climate work in concert to passively cool the house."
Watermelon tourmaline has been said to be a stone of reconciliation, a stone that fosters compassion and cool headedness, radiates the energy that attracts money, healing and friendship while stabilizing, grounding and reaffirming our Earth roots.
