Airlight- Switserland. Specialized in Lightweight and large span: Tensairity. Tensairity allows the construction of very light roof structures with extremely long span. The load bearing capacity of Tensairity is so high that with a pressure of 200 mbar it is already possible to build temporary bridges even suitable for heavy transports. Compared with traditional airbeams, Tensairity needs just 1% of air pressure. With such low pressure, air losses are easily compensated. floating structures, sport equipment, airships and even aerospace applications are possible. pics at
