Why Don't Penguin Feathers Freeze?

Why Don't Penguin Feathers Freeze? | Biomimicry | Scoop.it

"Despite living in frigid temperatures and getting wet, penguins’ feathers remain free of ice. How is that possible? [...] The answer is in the microstructure of penguins' feathers. The feathers are comprised of “a network of barbs, wrinkled barbules and tiny interlocking hooks. In addition to being hydrophobic, this hierarchical architecture with grooved structures is anti-adhesive. [...] Based on their discoveries about the feathers’ microstructure, the scientists recreated the design in a nanofiber membrane that could be developed into an ice-proof material, which they say could potentially be used in applications such as electrical insulation."

Bubble Surfing Brings Savings

Bubble Surfing Brings Savings | Biomimicry | Scoop.it

"Penguins release streams of lubricating bubbles from their feathers to help them surge out of the sea. Now shipping engineers and operators are looking for similar ways to reduce friction between ships and sea water, with a system that releases air to create a carpet of bubbles along the bottom of the ship."
