A Feasibility Study of Methods for Stopping the Depletion of Ozone Over Antarctica

Executive Overview

The purpose of the study conducted by Project Equilibrium was to determine ways of stopping the ozone depletion in the ozone hole over Antarctica. The three basic objectives of the study were as follows:

Two basic ways of attacking the problem were identified. First is replenishment of ozone as it is being depleted. Second is elimination of ozone destroying agents from the atmosphere. The second method is a more permanent form of the solution.

Any design of a possible solution requires specification of replenishment or elimination mechanisms, delivery systems, power systems, and support systems. Possible replenishment mechanisms are photocatalysis and electric discharge. Elimination mechanisms include molecular sieves and precipitates. The delivery systems may be either ground-based, lighter-than-air, or heavier-than-air. Possible power supplies are nuclear, chemical, wind, solar, and microwave. Support systems include any required ground stations, vehicle navigation system, and weather and ozone monitoring facilities.

By no means are the possibilities presented in this report complete. Since a detailed analysis was beyond the scope of this study, the final product is a set of recommendations in the form of questions that will need to be answered by future studies on the problem.

The hole may not be critical at the present, and the ozone loss may be a phenomenon peculiar to the South Pole, but in-depth studies into possible solutions should be made now before the problem ever does become critical.
