  • "Lilypad" Floating City

    Made In Space

    The Lilypad Floating City has yet to be built, but you have to admire the concept and design. Predictions of rising global sea levels due to climate change led architect Vincent Callebaut to develop the "Lilypad" concept - a self-sufficient floating city designed to accommodate up to 50,000 people displaced from homes in low lying areas.

    The floating "ecopolis" was inspired by the highly ribbed leaf of Victorian water lilies. The structure's shape helps reduce and manage undersea stress and pressures.

    The double skin of the engineered "Lilypad" would be comprised of polyester fibers, covered by a layer of titanium dioxide (Ti02). The Ti02 would react with ultraviolet rays to absorb atmospheric pollution via a photocatalytic effect.

    Each of the zero-emission floating cities are powered with renewable energy, including solar, thermal, wind, tidal and biomass. Rainwater is collected in the inner vortex and gravity fed to the water purification system. Freshwater storage, as well as other mechanical systems are located in the deepest portion of the structure.

    A centrally located artificial lagoon, totally immersed below the water line, acts as a ballast for the city. Suspended gardens and aquaculture farms used to grow food and biomass are also below the water line. Up top, the lagoon is surrounded by three marinas and three mountains, dedicated to work, shopping and entertainment.

    The "Lilypads" can be anchored close to land or allowed to follow ocean currents.
