Air moving device includes a housing, an impeller in the housing for generating a downward air flow, and vanes in the housing in close proximity to and a selected distance below the impeller to straighten the air flow. The device produces an air flow that substantially remains in a column over a substantial distance. The method includes producing an air flow that substantially remains in a column over a substantial distance and directing the air flow from the ceiling towards the floor to provide temperature destratification of the air in an enclosed space. The method also includes directing warm air from the ceiling to the floor and storing heat in the floor, apparatus on the floor and ground under the floor. The stored heat is released when the ceiling is cooler than the floor.
