A new frontier in urban living could rise above the waves, where innovative engineering meets the challenge of climate change. This video explores the complex science and technology needed to create self-sustaining floating cities. From the principles of buoyancy that keep massive structures stable to the renewable energy systems that could power entire communities, engineers are designing solutions that blend sustainability with resilience. With rising sea levels threatening coastal populations, floating cities offer a bold alternative—transforming the ocean into habitable space while minimizing environmental impact.

Beyond the structural challenges, the success of such cities depends on intricate networks of transportation, food production, and waste management, all designed to function harmoniously in a marine environment. Advances in mo ...
