When top engineers in Germany wanted to build a more energy-efficient car, they headed to the natural history museum to study dolphins and sharks. But it was the boxfish (盒子鱼)that interested them.
“We were surprised when this clumsy-looking fish became our model for designing an aerodynamic (空气动力学的)car”,says Thomas Weber. He is the research and development chief for the car company Daimler. An aerodynamic design reduces wind drag and increases fuel efficiency.
The boxfish may look clumsy, but it can start, stop,back up and zigzag (曲折前进)through the water with ease. And it does all this using surprisingly little energy. Daimler’s bionic (仿生学的)car is modeled on the fish’s boxy skeletal (骨骼的) system. Like the fish, the car is fast and drives easily. It’s efficient too.
The science behind nature-inspired inventions is called biomimicry (生物仿生). Biologist Janine Benyus came up with the term. As co-founder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature’s best ideas.
