“We were surprised when this clumsylooking 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 natureinspired inventions is called biomimicry (生物仿生). Biologist Janine Benyus came up with the term. As cofounder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature’s best ideas.
This month,the Nature’s 100 Best List will be revealed at the World Conservation Congress (代表大会)in Barcelona,Spain. Benyus coauthored the list of natureinspired designs with economist Gunter Pauli.
In Zimbabwe,a country in southern Africa,engineers designed energyefficient buildings modeled on termite (白蚁)mounds (土堆). The buildings use vents (孔) to keep the air flowing and the temperature cool.
A company in Atlanta,US,developed a selfcleaning paint modeled on the lotus (荷花)leaf. When the paint dries,it becomes bumpy (不平的),just like the lotus leaf. Rain drops form on the bumps and roll off,carrying dirt along with them.
