{"abstract":"This article explores the concept of underwater cities, tracing their origins from science fiction to contemporary technological advancements and environmental considerations. It highlights the historical inspirations, including works by Jules Verne, and discusses how modern materials science and engineering make such cities more feasible. The article identifies key challenges, such as pressure resistance and waste management, alongside potential economic opportunities like tourism and marine research. It then introduces AquaMetropolis as a conceptual underwater city designed to harness ocean currents for sustainable living. This concept outlines features like oceanic energy hubs, transparent domes, sustainable agriculture, bioluminescent lighting, marine research facilities, and efficient transportation. The article further details the complex implementation steps for AquaMetropolis, including feasibility studies, design, energy generation, environmental impact assessments, and securing funding. It concludes by emphasizing the collaborative effort required for such a project and its potential as a model for sustainable living and environmental preservation.","abstract_source":"gemini_generated","authors":["Syed Atta Ullah SHAH"],"date":"2023-10-08","doi":null,"id":2099,"issue":2,"journal":{"issn":"3150-0390","name":"Journal of Unique and Crazy Ideas"},"pdf_sha256":"de9b855cdb422f967b9442f6f7bfa2d2de09357d865b8d5b033d2e142ceee691","schema":"scimatic-article/1","title":"Submerged Horizons: Navigating the Concept of Underwater Cities","volume":1}
