Transpiration is the evaporation of water from the leaves of plants and trees. The undersides
of leaves are dotted with hundreds of tiny openings called stoma. Carbon dioxide enters the leaf through these pores, and water escapes. A mature tree may evaporate hundreds of gallons of water on a warm, dry day. The process cools the vegetation and also allows the internal flow of nutrients. The familiar veins within leaves transmit the water to the stoma. Studies have shown that the branching 
veins, called a dendrite pattern, are spaced out for maximum water flow. This leaf vein pattern may help design engineers build more efficient irrigation systems.

Festo has been working intensively on the topic of bionics since the early 90s. In 2006, the Bionic Learning Network was launched – an association of renowned universities, institutes and development companies. Since this time, Festo has been developing and supporting projects and test objects whose basic technical principles are derived from a wide variety of principles found in nature.
Tensairity® is a revolutionary light weight beam element developed by Airlight Ldt. The synergetic combination of an airbeam, cables and struts leads to this extraordi
nary light weight structure, using very low internal pressure but with the load bearing capacity of conventional steel girders.
