As green energy technology develops, more and more designers are channeling their creativity into environmentally friendly projects. Architect Renzo Piano designed a more efficient wind turbine that operates with only two blades. Bringing Piano’s design to life, ENEL Green Power, an international renewable energy corporation, started preliminary tests on the mini-wind-blade turbine in the Province of Pisa.
When compared to traditional turbines, the Dragonfly Invisible Wind Turbine can withstand stronger winds, but is also capable of functioning in low-intensity winds. The technique lies in the slim-line design of the turbines, which is developed to mimic the form of a dragonfly in flight and how it can glide through gale-force winds.
The lightweight materials – carbon and polycarbonate – used to construct the Dragonfly enables it to harness the lightest of winds, generating power with only 2m/second and at low altitudes. Initial performance of the light-weight turbine has been fruitful, having generated over 1200KWh.
At a standstill, the blades of the Dragonfly align vertically with the turbine tower, which is 20m high and only 35 cm in diameter. Piano designed this turbine to have as little visual impact as possible. According to the Enel Green Power, the size and style of the dragonfly might make it possible to place wind energy generators into residential properties.
