The Lilypad, is a concept for a completely self-sufficient floating city intended to provide shelter for future climate change refugees.

Through a number of technologies (solar, wind, tidal, biomass), it is envisioned that the project would be able to not only produce it's own energy, but be able to process CO₂ in the atmosphere and absorb it into its titanium dioxide skin.

Each of these floating cities are designed to hold approximately around 50,000 people. A mixed terrain man-made landscape, provided by an artificial lagoon and three ridges, create a diverse environment for the inhabitants. Each Lilypad is intended to be either near a coast, or floating around in the ocean, traveling from the equator to the northern seas, according to where the gulf stream takes it.
