Biomimicry:The Kingfisher and The Bullet Train
The kingfisher has the ability to go from one density of medium (Air) to another density of medium (Water) without a splash, This helps them catch the fish without alarming them. This ability of the kingfisher is due to the structure of its beak and head. This was adapted in designing the famous bullet train of Japan which travels at the speed of 200 miles per hour. It was called the bullet train because it was rounded in front. But during the initial phase every time it went into a tunnel it would build up a pressure wave and would create a sonic boom. This made life of the residents in the vicinity very difficult. The engineer who was involved in the design had to find a way to quite the train. Luckily he was a birder and he studied the kingfisher. This gave him the idea of redesigning the trains head. The re-design not only got rid of the noise but it also made the train 10% faster and 15% more efficient.
