A 3,000 square foot "solar greenhouse" using soap foam as a temporary, night-time insulation. ET Foam Home is short for Emerging Technology Foam-Insulated Solar Greenhouse. The frame is a tetrahedral space truss. Hydroponic bib lettuce grown within.
Where is this greenhouse located? On the bubble roof website they suggest 3 feet you only use 1,5 between the 2 layers of plastic. What kind of insulation is achieved?
What was learned by the New Alchemy people and the Institute of Man and Resources who took over the operation of the Arc project that was built for the UN Habitat conference of 1976 - was that north opaque, insulated walls are not able to produce good commercial results. Do have a look a SolaRoof technology, where our approach to Bubble Insulation is similar (we are OpenSource) but we use bubbles in the north wall to provide a light scope and insulation for winter and reverse this in summer.
Reminds me of some of the designs done by the New Alchemy Institute back in the '70's and '80s. They usually tried to add more thermal mass (in the form of earth, masonry or tanks of water) to help moderate temperatures in cold weather (yes, I know you're using phase-change salt panels to try to accomplish the same effect).

Nice work!

Keep up the good work!
