the latest project from argentinian artist tomàs saraceno is ‘solar bell’ — an aerial wind sculpture which examines his vision for the future of flying architecture. the floating model plaza is lighter than air, fully lifted by the wind, and built using the latest technologies in the fields of sustainable wind energy. the design engages progressive construction materials — light carbon fiber tubing for the framework and thin, flexible solar panels for the sails. through ‘solar bell’ saraceno conceptualizes the hypothesis of levitating architectonics, eventually hoping to apply his system to the construction of a floating arena, or a hovering observation tower. saraceno imagines the final realization to be 60 meters high, lifted entirely by the power of the wind — a flying building which people can steer, sit or stand on. working closely with the aerospace engineering faculty at TU delft in the netherlands, saraceno predicted the weight that can be supported by the triangular, four sided pyramids that comprise the kite structure.
