In the future, electricity will be developed on photosynthesis technology. To do this, it will be built a lot of sites for the plant, which after 20 years have become a dome over the old town.. Under the dome is the center of the city, in which there are high-rise buildings, offices and administrative buildings. The houses of the business class turned into cottage areas outside the dome. This city is built on a swamp. From the swamp, the city takes clean water, minerals (oil?), grows fish and algae.
