A futuristic floating city on the ocean, with a modular and sustainable structure. The city is made up of interconnected hexagonal platforms, forming a network that floats on the water. Large green structures are dedicated to vertical farming, with hydroponic gardens and multi-level orchards for self-sustained vegetable production. Surrounding the city, water desalination systems can be seen, with large pipes and solar-powered devices that extract and purify seawater for consumption and irrigation. The architecture is minimalist and eco-efficient, with white surfaces and glass that reflect sunlight. Everything is surrounded by an intense blue sea under a clear, bright sky, creating a sense of a sustainable future in harmony with nature.
