Lilypad Floating Eco City Concept

A strange vision from a future in which many people are displaced by climate change and rising sea levels, these Lilypad cities are designed to support up to 50,000 inhabitants a piece. As a critical part of their energy self-sufficiency (alongside wind and solar power of course) is biomass reuse so that these giant habitations don’t have to dock to refuel on biological supplies. Whether these will ever be a reality, however, remains to be seen.
