Intro
Hui Gwan :
We will go to electricity museum from now on.
One, two, three go!!
Jae hyeok
: Where are we?
Hui Gwan :
I did a mistake and teleport us another place.
Min Hyuk :
Oh! Look over there.
Na Young :
Let’s go
At museum
Jae hyeok : We
arrived at here. Here is electric museum. From now on we are going to look
around this museum. Each person is going to explain this museum each part
Part 1. History of electric energy
Won Hyeok : The
name of this corner is history of electric energy. This corner shows chronology
of the birth and development of electric energy. It is watt's steam engine it
is famous for its driving force of the Industrial Revolution. It is the first
power generation facility in Korea. As shown this is a scale model. It is the
first public transport - electric train. In 1899 the 동대문 power plant supplied electric energy for electric
train
Part2. Extension of electricity
Na Young : In
1930s, there were large bodies of water in North. Korea. So, there were 21
hydroelectric power generations around river. Above all, ‘soopoong’
hydroelectric power generation that length is 900m along the Amnokgang(Amnok
river) is famous for large scale generation of electricity. The scale is that
long time ago, it could transmit electric power to South Korea. It is very
amazing thing!
Now, I will introduce
how power can be transmitted to our home. First, voltage is increased at
hydroelectric power generation and sent to substation. And then voltage is also
sent to pole transformer from substation. Let’s look at it! This is pole
transformer in 1930s. Finally, voltage is decreased and sent to our home. So we
can use electricity. Thank you!
Part3. Electricity in our life
Min Hyuk : Electricity, one of the most
important things in our lives has been changed our life a lot.
Telecommunication and radio broadcasting using the electricity have been an
remarkable progress. Telecommunication has commercialized at 1890s by
physicist, inventing a telegraphic instrument and a telephone using
electricity. It was not until 1920s by the invention of ‘A vacuum tube radio’
the road of radio broadcasting has opened widely.
In this section you can see many kinds of
electricity devices. And here you will see familiar things such as movie
projector, Korean typing machine and electricity calculator.
Gramophone which Korean name is Chuck-Um-Ki,
remembers the person’s voice and repeat it exactly the same. Edison the
inventor of thins machine has installed his own company but unfortunately it
couldn’t have been progressed because of the other inventions. You can see that
other inventions in this area. Here are hair curling iron, waffle maker,
toaster and there are many kinds of tea pots.
Electricity has come deeply into our life and
allow us to have convenient life.
Part4. The development process of lighting
Hui Gwan : Hi, This place is about the electric light
brightening over the Korea. We can see the development progress of lighting in
this place. From instruments before people used the electricity to modern light
like the bulb. There are so many things people used to lightening the dark.
Let's check what they are. First,
This is flint. Ancient people used this flint to lightening the dark. If you smash these stones each other, it makes a spark and
the spark makes a fire. Ancient people used a fire as a lig.ht
After then people used candle and
lamp. For example, this is Ho-Long in Korean, people used this Ho-Long when
they worked or studied in the room, at night. and this is Nam-Po-Deung. and it
was usually used in 1960s and people used Nam-Po-Deung for moving in the dark.
These are initial bulbs. As you
know, Edison invented the bulb. First time, he used carbon to make filament.
But now, we use tungsten or nickel to make filament. Because its durability is
better than carbon. And this is the initial flashlight. As you look at it, It
is too big. The Flashlight have become smaller and smaller. Now we use more
portable flash light.
In our daily life, there are so
many bulbs for so many purpose. For example, this is for car, this is for
Christmas tree, this is for electric test, this is for train. Until now, we
checked the development progress of light. We can lighten the dark easily now.
But I wish we should not forget the day we were hard to lighten the dark. And
we can recognize the minor thing's importance. Thank you.
Part5.
Electricmagnetic and Electric power plant
Jae hyeok : Hi guys.
Here is electromagnetic part.
Take look at here. We can see many stuffs and
many buttons here. We can know what kind of magnetic waves are made by them.
Let me try this, I will push this button and let’s check it. We can check how
much waves are made by here. Microwave is 20 and mixer is 30 and here is
another 3stuffs hairdryer is 70, the biggest one and here is last three. Push
it again. Yes 20, 30 and 10.
Come this way.
This part is about power plant. Unfortunately
here is no nuclear generation power plant. But here is thermoelectric power
plan, hydroelectric power plant and water pumping power plant. I think most of
you guys already know what is hydroelectric and what is thermoelectric so I
will explain briefly what is water pumping power plant.
Look at here, you can see blue circles. At first
it follows this way but next it changes flow direction. At night people don’t’
use much electricity so there must be surplus electricity and we can use them
when we pull up the water higher and then next day we can use the water when we
make electricity that’s how water pumping power plant is working.
And here is another funny thing. This is quiz
machine. Touch the screen first and then touch a circle. It looks like each
circle is a quiz. You can check what you know here.
Thank you guys. I will finish now.
I really think this place is pretty good. If you
have the time to visit here, come here. Here is interesting than what I
expected. Bye~
After
watching
Hui Gwan : Now, we will
finish our project and we will go to home and have dinner.
Everybody : Bye~
