The idea is by making an orbital tower which will vertically reach out to the space and horizontally spread it`s solar panel. In order to create this gigantic tower which will provides the world energy needs, a large amount of materials are needed. Therefore, there will be only 3 tower which will be built across the earth. This condition will have a major effect to the countries near these 3 orbital towers. Due to the "energy sharing" policy, several countries will unite and create an association.

As result the world will divided into 3 blocks. Each country which join one of these blocks will have their cultural, political, economy and lifestyle affected since some countries will merge and create a new country. In the merging process some of the country will have a war and some of them willingly surrender for the good of their people.

As one of the civilian and architect of this era, it becomes important to influence other people not to rely too much on these 3 orbital towers as their energy sources and try to have a "self sustaining" and "sharing" habit. It is not only because of the advantages it provides but also the possible threat that will occur in the country (riot, or war).
