Like everyone else has said, this is living off the grid at its best. Water catchment system for showers, solar power for electricity, and yet still able to have internet, lighting, refrigeration, fans and a comfortable bed. Even though it was summer and these 1990s lava fields are black, a nice breeze blew through the deck area joining the 2 sides of the tiny house, we never felt hot, and we were comfortable sleeping at night. Kilauea lava flow lit up the sky at night, and while unfortunately was destroying homes 10 miles away, this was, by far, the coolest, most memorable place we have stayed the entire trip. If you're headed to the Big Island to experience the volcano, this is the only way to do it.
