You might know Renzo Piano as the architect behind many of the world’s leading museums, but get ready to meet Renzo Piano, wind-turbine expert. Testing has commenced on Renzo Piano’s small-scale wind-turbine blade at the Molinetto Test Field near Pisa, Italy. Piano’s turbine blade resembles a dragonfly’s wing and incorporates elements from the insect that promote stability in flight in order to allow the turbine to tolerate gale-force winds.
