Hoistway mechanics of panoramic vacuum elevator

A method for vertical movement of a cabin apparatus through a hoistway shaft of a hoistway apparatus, the method comprising:

• forcing airflow in and out the hoistway shaft, thereby maintaining a difference in air pressure between overhead air pressure above the cabin apparatus and underneath air pressure below the cabin apparatus;
• wherein the maintaining the difference in air pressure between the overhead air pressure and the underneath air pressure causes the cabin apparatus to move;
• wherein, when the difference in air pressure between the overhead air pressure and the underneath air pressure meets ascending criteria, the cabin apparatus ascends through the hoistway shaft, and, when the difference in air pressure between the overhead air pressure and the underneath air pressure fails to meet the ascending criteria, the cabin apparatus descends through the hoistway shaft;
• detecting an emergency;
• based on the detecting the emergency, activating at least one of one or more valves controlling the airflow in and out the hoistway shaft, thereby preventing, at least in part, the airflow from entering or escaping the hoistway shaft, and thereby decelerating movement of the cabin apparatus through the hoistway shaft.
