The world's first city floating in the sea, 2 years can be around the earth

Freedom Ship company proposed the latest idea of the floating city. The city is called Liberty floating sea city: it can be floating in the sea, is divided into 25 layers, for 50,000 people living, schools, hospitals, parks, airports and other facilities.

In addition, the floating city can receive 30,000 tourists a day, 10,000 guests can spend the night on board. In addition to building basic public buildings, various recreational facilities will be constructed, which can be said to be readily available.
Freeway International, Florida, USA, also plans to build an airport on the roof to make the lives of its residents more convenient.
Freedom Floating cities at sea are powered primarily by solar and wave power, with 70% of the time staying near the coast of the metropolitan area and 30% of the time moving between countries
The main route is from the east coast of the United States to the Europe via the Atlantic Ocean. It travels through Italy to Africa, passes through Australia to the north and enters Asia. It eventually returns to the west coast of the United States and enters South America.
The floating city will include: 18,000 living space, the price of 180,000 ~ 2.5 million US dollars, ultra-luxury rooms will be more than 44 million US dollars. 3000 commercial space, the price and living space is similar. 2400 public places, 10000 hotel rooms.
