Kingfisher: The Original Bullet Train EngineerHow biology silenced high-speed rail noise

Nature Solved It First

Nature often holds the key to solving complex modern engineering challenges. Japan’s Shinkansen trains faced a critical issue with sonic booms created when entering tunnels at high speed. Engineers looked to the Kingfisher, a bird that dives into water without a splash, for the solution. By mimicking its beak, they eliminated the noise, increased speed, and improved energy efficiency.
