Mandeep Singh, a graduate student from India, conducted research on lunar earthbag structures for his master’s thesis at Auburn University, Alabama. This is a very interesting and exciting find that has obvious applications here on earth, particularly for the construction of lightweight, insulated vaults. Custom shaped, top connected bags were filled with vermiculite with a screw auger. It may be possible to fill bags with sand or loose, dry soil and eliminate tamping with this method. Another big thanks to Patti Stouter for finding this paper.
