The Ilhyeon Windows story devoured every other issue in the Republic of Korea.

—Professor. In what manner does this work?

On the broadcast, talk was flowing about the solar window Ilhyeon Windows was said to have developed.

—It is a double-lamination method, in which solar generating panels are laid finely between one pane and another. So the energy of the sunlight is gathered while the sun is up and then used.

—In that case, in the case of an ordinary household, how much energy might be obtained through the windows?

—If one calculates it mathematically…

The professor who had come on the broadcast carried on his explanation, making diligent use of the materials he had brought.

And the announcer listening to him let out exclamations and expressed his astonishment at Ilhyeon Windows' technology.

—So what you are saying is that in the case of an ordinary household, half of a day's energy can be obtained through the window Ilhyeon Windows has developed.

—That is correct. In the case of a typical apartment, it appears that something like half of a day's consumption can be obtained as energy through solar generation.

—That would be of enormous help.

—And this benefit is expected to be greater in office buildings than in ordinary households.

At the professor's words, a table of solar energy efficiency calculated on the basis of the 63 Building came up on the screen.

—The 63 Building of course, but many buildings besides have their entire wall surfaces covered in glass. If all of it were changed to the solar windows Ilhyeon Windows has developed, there is a strong possibility that the efficiency would be maximized. And the efficiency so obtained would yield the effect of newly building ten nuclear power plants every year.

—Ten nuclear power plants?

—Yes. It becomes possible to obtain energy in the quantity of ten nuclear plants.

The professor looked at the announcer with a serious face and said,

—Ours is a country in which not one drop of oil is produced. We are in the position of having to import oil from abroad. But…
