Lilypad - architectural design floating cities

Project Lilypad, and his second name literally sounds as "Floating Ecopolis for climate refugees." This island city will only use natural sources of energy (solar, wind energy, tidal energy, etc.), so it should not cause any harm to the environment. Isle of greenery both outside and inside, where there is a real oasis of different exotic plants, and the construction itself is made in the form of a water lily flower. It designed a floating city for 50 thousand inhabitants. Of course, these are just thoughts and dreams of the architect, have nothing to do with reality, but with the predictions IPCC (Intergovernmental Panel on Climate Change), under which the sea level during this century will rise by 20-90 cm, it looks like it A step in the right direction.
