Eiji Nakatsu Essay

The Japanese engineer, worker of JR West and birdwatcher as well, Eiji Nakatsu, used his knowledge of the silent flight of owls and splashless water entry of kingfishers to plunge the sound generated by the trains. This situation surged from the necessity of reducing acceptable noise-pollution level produced by high-speed trains due to the fact the trains ran through dense neighbourhoods and many tunnels. “As they drive through, air pressure builds up in waves and, when the nose emerges, can produce a shotgun-like thunderclap” (4). The loudest noise emerged of the trains from the tunnels on the line. This dynamic was so forceful that it was creating sonic booms that may lead to the residents, within an area of 400 meters away, suffer from intense headaches.
From Kingfishers ability to move quickly from the air- a low-resistance medium- to water -a high-resistance medium Mr. Nakatsu could solve this inconvenience. The kingfisher's beak provides an almost ideal shape for this conditions. it “is streamlined, steadily increasing in diameter from its tip to its head”, therefore this little change reduces the impact to extent that the kingfisher dives into the water, letting the water “to flow past the beak rather than being …show more content…
Most of the current examples focused on the mimicry of structural forms from nature and using the digital tools as to define, shape and test these complex structures to conceive a solution that complement and be part of our world. During the last decade, there was a step forward in the biological systems understanding and our challenge is to apply them into many disciplines and life imitation has become the best approach for us so as to be a part of their built environment and to convey audacious ideas to our surroundings (3; 2;
