Green Float botanical city
A Japanese technology company designed the Green Float concept to be self-sufficient and carbon-negative, allowing mankind to live harmoniously with nature. Each floating cell district has a radius of .62 miles that can house 10,000 to 50,000 people. Carbon dioxide and wastewater from the urban areas become nutrients for the plants, and grains, livestock and fish live along the base and ocean shallows of the tower. Green Float is powered via solar energy, ocean thermal energy conversion and wind and wave technologies, and such cities would be located along the equator where the climate is stable and not prone to hurricanes.
