Scent-free wildlife blind

Abstract

The invention is a scent-free wildlife blind. The blind has a room-like shelter having a door, a plurality of windows, a small vent near ground level, and a flexible tube extending from the top of the shelter to a height of approximately 30 feet from the ground. When the wind hits the shelter, the windspeed will be higher at the top of the tube than at the bottom vent. The pressure exerted by the wind on the air inside the shelter is inversely proportional to the wind speed. Therefore, the pressure difference will force air in through the bottom vent and out through the top of the tube, carrying the scent of the occupants out of the blind high enough so that nearby animals will not smell the occupants.
