Floating cities

The Dutch are accustomed to building in flood-prone areas so perhaps it’s only natural for them to construct floating cities to cope with climate change. According to design company DeltaSync, such cities would be built to rise along with the sea level. Large blocks of polystyrene foam connected by frames of strong concrete would be used to float the dome-shaped buildings, and these structures would be linked via floating pedestrian bridges. Floating highways would even connect these aquatic cities, and heat drawn from the ocean’s surface would heat the city.
