We are now researching some specific numbers about how much water is needed to store heat in a greenhouse.
My colleague Tracy Hightower gave me this link to research done by ATTRA (National Sustainable Agriculture Information Service) references Solviva and Three Sisters regarding Greenhouse Waterwalls. More information about Waterwall is available here on a free ebook that documents the poineering work at Solviva.
They also give mention of Rick Nelson’s SolaRoof Work in the middle of the very long webpage. Rick’s colleague Bård Hans Sylling will be coming to Arcosanti tomorrow to present the SolaRoof concept to staff and community members here.
