Air conditioning eventually reach the upper atmosphere. Once the refrigerant reaches the stratosphere, UV radiation from the Sun homolytically cleaves the chlorine-carbon bond, yielding a chlorine radical. These chlorine radicals catalyze the breakdown of ozone into diatomic oxygen, depleting the ozone layer that shields the Earth's surface from strong UV radiation. Each chlorine radical remains active as a catalyst until it binds with another radical, forming a stable molecule and quenching the chain reaction. Prior to 1994, most automotive air conditioning systems used R-12 as a refrigerant. It was replaced with R-134a refrigerant, which has no ozone depletion potential. Old R-12 systems
Captain Video: Master of the Stratosphere 1960, and 1963). Harmon and Glut describe this serial as a "rather shoddy, low budget space cliffhanger." The serial includes several science fiction gadgets of the era. The Opticon Scillometer was used for looking through walls. Objects were made to disappear with the Isotropic Radiation Curtain. The Mu-ray Camera could photograph lingering images after the event. Temporary madness could be caused with the Psychosomatic Weapon. A variation on Radar was entitled the Radionic Directional Beam and the Radionic Guide and a Vibrator gun that worked like a Tazer.
