Solar-Integrated Rainwater Infrastructure
A venture that turns a single roof into two forms of self-sufficiency — rainwater harvested to certified drinking quality, and the power the house runs on. One surface, two outputs. It begins with the restoration of old stone houses, and a savings-based model carries the same autonomy to homes far beyond them.
"The same surface we install for the sun is the surface that catches the rain."
