ABSTRACT:
The waste material holding tank located within a portable, outdoor toilet cabana is vented to atmosphere by a vent pipe extending upwardly from the tank to the roof of the toilet cabana. A small, electrical blower fan is mounted upon the upper, open end of the vent pipe for sucking air from the holding tank and blowing the air to outside atmosphere. A solar energy panel is mounted upon the roof of the cabana near the fan and is electrically connected to the fan. The panel generates electrical energy in response to a predetermined level of sunlight for electrically energizing the fan. Thus, the fan circulates air through the holding tank during the items that the sun is shining upon the cabana, to reduce the solar heat build-up in the holding tank for reducing the generation of noxious odors caused by heat induced reactions in the waste material in the tank.
