Bird’s Head inspires Bullet Train efficiency

Japan’s “Bullet Trains” travel at up to 320 kilometres per hour. However, trains coming out of tunnels at those speeds make a very loud noise like a thunderclap (because of the change in air pressure on emerging), which annoys local residents.

So Bullet Train chief engineer Eiji Nakatsu asked himself, “Is there something in Nature that travels quickly and smoothly between two different mediums?”

An avid birdwatcher, Nakatsu thought of the design of the kingfisher that dives into water for fish with very little splash. Copying the shape of the bird’s head to remodel the front of the Bullet Train resulted not only in a quieter train, but also one that uses 15% less electricity even while the train travels 10% faster.

Nakatsu recognised the design in ‘Nature’ was worth copying. That design didn’t come by itself, but needed a Designer. The Bible tells us Who that Designer is –

He is the image of the invisible God, the firstborn over all creation. For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him. He is before all things, and in him all things hold together. And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy.
