Japanese bullet train (Shinkansen)

One hurtles past a station in Japan every 2 minutes!

Developed in the the 1960’s

275 kmph transport, but pressure wave, deceleration and consequent sonic boom at exit from tunnels

1989 – call for more speed and less noise

Bird watcher and engineer Eiji Nakatsu examined problems after 30 years unresolved

Studied kingfisher’s complex beak (silent entry into water from the air at high speed)

BT’s are now faster 320 kmph, 15% less energy, train nose is now 15 metres long – modelled on kingfisher’s beak

Marvellous lessons to be learned, and perspectives gained from nature
