Transcript of Copying Nature's Designs

Bullet trains
[in Japan] / can move people
city / at speeds of almost 300 kilometers per hour.

Building vehicles [that move this quickly] / took a lot of thought.

Some of / the original models / of the bullet train / did not run /
as smoothly

When the high-speed trains / went from the wide open outdoors / into a narrow tunnel, / they created a very loud sound.
Quieter Rides
Copying Nature's Designs
When building the first airplanes, / designers studied birds / and how their wings /
in the wind.

The inspiration [for
] / came from / the hooks on
s, / the seeds of a special plant.

They have tiny hooks / on the outside /
so that
they stick to clothes or fur.
Keeping ships clean / is not / an easy task.

The more
time / (that) a ship spends at sea,
the more
the bottom of it / becomes covered with a thick and wet growth called

Not only

it cost / a lot of money / to clean fouling off, /
the chemicals [that
are used to
remove it] can be harmful / to the environment.

[scientists have been looking for better ways / to deal with /the problem].
Cleaner Surfaces
The idea of looking to nature [for design ideas] / isn’'t new.

In fact, / many inventions / have been derived from nature.

Now, there is even a new approach called
, [which specifically
focuses on
(which are) found in nature / to solve human problems.

Here are four examples / of how nature inspired invention
[that are already changing society].
Now, / engineering professor Anthony Brennan / believes [that he has found / a solution].

He made his discovery / by studying something [that spends all of its time / in the sea: sharks.

He noticed / [that the tiny pattern of a shark’'s skin /
s fouling
to its body.

Using this knowledge, / he created a material [that copies the pattern / of a shark’'s skin].

He found [that 85 percent less fouling / collects on surfaces / (
which are
) covered with this material than on smooth surfaces.
The benefits / don’'t stop there!

He discovered [that bacteria / do
stick to / this material,

Therefore, / it can also be used / on certain surfaces / in hospitals, /
such as
bed rails and tray tables, / to help (to) prevent the spread of
Eiji Nakatsu / looked to the natural world / to find a solution / to this problem.

He discovered [that there is a bird, / {called a kingfisher}, / that has the ability] to manage sudden changes / in air

It must do this when it dives from the air into water at high speeds to catch fish.
He studied the shape of a kingfisher’'s beak and designed the nose of the bullet train to have a similar build.

This turned out to successfully reduce noise and electricity usage.

Therefore, thanks to the kingfisher, bullet trains are now able to easily, smoothly, and quietly travel through tunnels.
Efficient Housing
When asked to build low-cost public housing, / a team of Slovenian designers / turned to nature for inspiration.

Bees are some of nature’'s best builders.

Therefore, / the designers decided to use / the
shape of
/ for [the cheap and efficient] housing construction.

Using this, / the Slovenian designers / created welcoming, brightly colored structures / with eco-friendly balconies.

The balconies (that are) [copying the honeycomb shape] were built with a covering outside and small holes / in their walls.
The covering protects / the apartments / from [the summer sun, and the holes]
let the heat inside

In turn, / it provides additional heating / to the apartments / in winter
warm air / inside.

helps regulate
the temperature / in the apartments all year round.

In addition, / the covered balconies’' smart design /provides privacy from neighbors.

Everyone can privately enjoy / the sweet comfort of their honeycomb homes!

In a modern world [that often values technology
nature, / it’'s interesting [that some of the most creative design ideas / were taken from the natural world].
Biomimicry is a major change / in thinking; it’'s based on the idea / [that nature is not just a resource, / but also a model and mentor].

This may be the key / to solving more challenges (that / which are) facing today’'s world.
