Yesterday a Japanese train company apologized for running 20 seconds ahead of schedule. How did Japanese trains get so fast?
The answer for how their famous bullet trains move so quickly is thanks in part to biomimicry, the study of using animals as a source for design. The front of the bullet train was inspired by the beak of a kingfisher which allows for more efficient airflow and thus less of an environmental impact. This is merely one example of the interesting world of using the evolution of animals to design the world around us.
Japanâ€™s Shinkansen doesnâ€™t look like your typical train. With its long and pointed nose, it can reach top speeds up to 150â€“200 miles per hour.
It didnâ€™t always look like this. Earlier models were rounder and louder, often suffering from the phenomenon of “tunnel boom,” where deafening compressed air would rush out of a tunnel after a train rushed in. But a moment of inspiration from engineer and birdwatcher Eiji Nakatsu led the system to be redesigned based on the aerodynamics of three species of birds.
Nakatsuâ€™s case is a fascinating example of biomimicry, the design movement pioneered by biologist and writer Janine Benyus. She’s a co-founder of the Biomimicry Institute, a non-profit encouraging creators to discover how big challenges in design, engineering, and sustainability have often already been solved through 3.8 billion years of evolution on earth. We just have to go out and find them.
