CO2 and Entertainment in El Paso and beyond

Carbon dioxide (CO2) has been used in entertainment for a long time. The gas is cooled to a liquid to easily (and economically) achieve special effects like fog and haze. Most have seen haze effects at concerts to emphasize a spotlight or on TV for cloud effects.

Low-lying fog effects can be created by using liquid CO2 that is typically stored in compressed cylinders. Low-lying fog is one of the effects of the liquid CO2 being used to decrease the temperature on theatrical fog which results in a denser fog that stays very low to the ground. Fog can also be achieved inexpensively by using dry ice. Technicians are able to boil water in large containers and then put a couple of pieces of dry ice in those containers. Carbon Dioxide cannot be maintained in a liquid form in atmospheric pressure therefore, it instantly becomes a gas. Typically there is a fan at the top of the container to blow that gas into the desired direction for the fog effects.

Liquid CO2 by itself can be used as an atmospheric fog in place of pyrotechnics in El Paso. This can be done by emitting liquid CO2 in the air via an electric solenoid valve. When the CO2 expands to a vapor and condenses moisture in the air, large clouds of gas are the result. Since the CO2 vapor disappears immediately once the valve is closed, magicians will use this type of fog creation.

The entertainment industry not only consumes copious amounts of CO2, but produces high levels of carbon emissions as well. This is due to transportation, onsite generators and pyrotechnical effects that require the CO2 gas. Consequently the Producers Guild of America has created the Green Production Guide to lower carbon emissions on various film and TV production sets.
