The Moon Cocoon is a small cloverleaf-shaped design for the construction of ''Superadobe'' buildings, containing a central living room and four smaller rooms. In the superadobe style, the Moon Cocoon's construction materials consist of coiled earth-filled sandbags, covered in a stucco or mud exterior. This ''tree free'' construction naturally regulates temperature, is earth quake resistant, and can quickly be built by a team of four to five workers.
The Geltaftan Foundation and Cal-Earth are a public nonprofit 501(c)(3) organization whose mission is to develop sustainable building practices in Earth and ceramic based architecture, and to educate apprentices in these practices. Its innovations have been published by NASA for lunar and martian construction models, and its apprentices have constructed superadobe homes and shelters in countries around the world, such as Australia, New Zealand, Costa Rica, Nicaragua, Iran, India, Mexico, Chile, Siberia, Tibet, South Africa, and throughout the United States.
