Visible Good designs and manufactures shelters that can be deployed in 25 minutes or less with 2 people and no tools. They have devised a lightweight, folding modular shelter called a Rapid Deployment Module (RDM) that is a hybrid between a trailer and a tent and can be used in emergency situations by first responders, aid agencies, and even educators and the military. The Rapid Deployment Module is a collapsible shelter that can be packed into a crate and quickly deployed anywhere in the world. When folded up, it can fit into a crate that is 7.5 feet long, 4 feet high and 4 feet wide, but once unpacked it can be set up in a half hour to create a 130-square-foot shelter complete with doors and windows. The RDM is built to withstand extreme temperatures ranging from the intense heat of the Sahara Desert to the bitter cold of Antarctica, and if someone needs more space, two RDMs can be fitted together to create a larger structure.
