The Silent Speed: How the Shinkansen Bullet Train Mimics Birds

TLDRThe Shinkansen Bullet Train was redesigned to be faster and quieter by mimicking the features of birds. The pantograph was inspired by owl feathers, the supporting shaft by the Adelie Penguin, and the train nose by the Kingfisher's beak. This biomimicry design reduced noise, increased speed, and improved efficiency.

Key insights

🦉The owl-inspired pantograph reduced noise by using serrations and curvature from owl feathers.

🐧The Adelie Penguin-inspired supporting shaft decreased wind resistance for better efficiency.

🐦The Kingfisher's beak shape was used in the train nose design, reducing noise and increasing speed.

🚅The redesigned Shinkansen Bullet Train debuted in 1997, achieving a 10% increase in speed and 15% decrease in electricity usage.

🌍Biomimicry is the practice of imitating features and processes from nature to solve design problems more efficiently.

Q&A
