Cooling Station builds on lessons learned in fabricating One Fold Cooling Station builds on lessons learned in fabricating One Fold and Cocoons to achieve a significantly larger sheet metal construction. Instead of using the simultaneous folding/braking operation and purpose-made machine required by One Fold, Cooling Station uses a conventional sheet metal brake. Folding the edges of stainless steel sheets creates inverted keystone-shaped units with flanged edges for ease of connection. By joining these units together, it is possible to form sheet metal cones which can then be stacked to create extremely light weight large-scale towers with robust spatial and structural characteristics.
