Penguin Feathers May Be Secret to Effective Anti-Icing Technology; McGill Researchers Develop Potentially Chemical-Free Solution to Ice Build-Up on Electric Wires, Wind Turbines, and Possibly Even Airplane Wings

Gentoo Penguins

Ice buildup on powerlines and electric towers brought the northern US and southern Canada to a standstill during the Great Ice Storm of 1998, leaving many in the cold and dark for days and even weeks. Whether it is on wind turbines, electric towers, drones, or airplane wings, dealing with ice buildup typically depends on techniques that are time-consuming, costly and/or use a lot of energy, along with various chemicals. But, by looking to nature, McGill researchers believe that they have found a promising new way of dealing with the problem. Their inspiration came from the wings of Gentoo penguins who swim in the ice-cold waters of the south polar region, with pelts that remain ice-free even when the outer surface temperature is well below freezing.
