Australian company EnviroMission has recieved approval to construct a 130-meter wide, 1-kilometer tall tower that will generate electricity from currents of air heated within a 7-kilometer greenhouse surrounding the tower's base. It is predicted to generate 670-gigawatt hours of energy per year, providing a clean source of energy for some 200,000 homes."
