Hot air will drive turbines to create electricity , then flow out through a tall chimney . Solar chimneys allow the rising air to go out of the building , taking the heat with it . The hot air is cooled by the cold water in the pipes and flows back into the building as steam. EnviroMission , an Australian company , wants to build it in the Arizona desert .
