In October of 2014, we held a weekend workshop with Texan inventor and metal smith Harvey Lacey. Expanding on his previous designs, we built a bigger leverage-driven polystyrene compression machine with reclaimed wood, most of it from shipping pallets. We shredded and bagged a large amount of polystyrene, which we then used to make Ubuntu-Blox in the new machine. The freshly compressed Ubuntu-Blox were used to build a new wall for the Earth Nurse community in the historic village of Agua Fria here in Santa Fe. It was a pleasure working with Harvey and Glenda, his wife, and we look forward to welcoming them back to Santa Fe for more workshops in the future.
