The document discusses the design of a future floating city called the hO2+ scraper. It is described as an autonomous unit that functions as a self-sufficient floating city, generating its own power through renewable sources and producing its own food. The design aims to have zero negative environmental impact and even improve the environment. Unlike traditional skyscrapers that consume large amounts of resources, the hO2+ scraper would break free from existing urban infrastructure and float autonomously in the sea, providing living and working space for users in a sustainable, eco-friendly manner.
