Description

The ecosystem of the earth is now continuing with explosive growth in population. This means that in the future, oxygen supply may not be possible for all humans to live together on a smooth land. Moreover, global warming is causing sea level rise continuously.

Furthermore, if the lowlands are slowly submerged in water, the residential life of mankind is restricted, and the desertification of the land is also limiting the residential life of mankind.

In order to solve the limitations of residential space which is closely related to the survival of these human beings, there is a need for a new environment in which there is no oxygen or lack of oxygen necessary for human life such as resolution, underwater city, underwater city, underwater city, There is a need for the development of construction technology for the survival of living things including humans.

In the case of resolution, a lot of development has already been done, but underwater cities and subsea cities are relatively slow technological development. In particular, it is true that subsea cities are developed only for small-scale tourism products and lack a lot of commerciality.

In addition, underwater cities under the rivers and lakes, underground cities in the ground and underground cities can secure fresh water, so renewable energy systems for oxygen and power supply will be needed to survive, including humans, A space city that can be supplied with oxygen will also need a renewable energy system for oxygen and power supply.
