Architect Vincent Callebaut designed Lilypads to be self-sufficient floating cities that can each accommodate up to 50,000 climate change refugees. Inspired by the shape of Victoria water lilies, these eco-cities would be made of polyester fibers and built around a central lagoon, and they would feature three mountains and marinas — dedicated to work, shopping and entertainment. Aquaculture farms and suspended gardens would be located below the water line, and the cities would run completely on renewable energy. Callebaut plans for his Lilypad concept to become a reality in 2100.
