The problem is that there is a lot of iteration while one designs these technologies. …show more content…
Frank Fish, a biologist saw bumps along the fins on a statue of a humpback whale and thought it was a mistake but the artist was right, the row of ridges helps the fins to cut through the water. When he added rows of bumps to the turbine blades it increased its efficiency and reduced the drag and noise. A Japanese engineer Eiji Nakatsu saw how a kingfisher dives into the water without splashing any water with the help of its narrow beak. He thus created the Shinkansen bullet train with the same design of a beak , this reduced noise , used less power and enabled higher speed. Tardigrades need water fro live, when outside water they cover their molecular mechanism with proteins , DNA in a sugar, this gave inspiration to a lot of biotech companies and their vaccines lasted as long as six months without refrigerating. Certain spiders weave their webs with a special silk rope in such a way that Ultra Violet rays are reflected, and thus birds can see these obstacles and avoid accidents.
