Acclaimed architect Rem Koolhaas gives elevators and escalators their due as part of his Venice, Italy exhibition, Fundamentals: the 14th International Architecture Exhibition, open to the public through November 23. It features such architectural elements as door handles and exposed machinery in a hanging, domed ceiling. Along with elevators and escalators, these are elements Koolhaas believes should become an integral part of architectural thinking. And some of them play a literally vital role, such as the missile-shaped elevator shown here. One of three designed by the Chilean Army and the U.S. space agency NASA, the capsules were used to rescue 33 trapped miners during the 2010 Copiapo, Chile, mining accident.
