Abstract: A solar chimney street lighting pole having a hollow pole with a first end and a second end, an air inlet circumferentially arranged at the first end and an air outlet arranged at the second end. Dome-like solar heaters are arranged along a length of the hollow pole. The hollow pole is vertically secured relative to the ground with the first end proximal to the ground, and the dome-like solar heaters configured to heat air inside the hollow pole using solar radiation, thereby creating an upward air stream therein. A fan is arranged inside the hollow pole and proximal to the air outlet. A controller is electrically connected to a sensor and a fan actuator to command the fan actuator to switch the fan based on the signal from the sensor. The solar chimney pole transports a polluted air proximal to the ground to the air outlet.

Abstract: The congregational prayer chair is designed to provide needed support for certain worshipers participating in Muslim prayer services. The chair is constructed with a seat and seat-back supported between two connecting arms. The connecting arms are mounted on chair legs. Grooves and tracks are provided on the arms that permit the seat and the seat-back to be moved in a predetermined manner so that a worshiper can attain the required prayer positions without disturbing the alignment of the prayer rows and the other worshippers.
