Danish firm BIG Architects has unveiled proposals for a 1 million m2 eco-island off the coast of Azerbaijan

BIG has worked with fellow Danish firm Ramboll to design seven inhabited “mountains”, which will be powered by tidal, wind and solar energy. The architect has calculated that 16 wind turbines, 20,000m2 of photovoltaics and 12 million m3 of seawater could power the island for a year.
