Carbon dioxide elongatus" has been genetically engineered to produce the fuels isobutyraldehyde and isobutanol from using photosynthesis. Liquid and solid carbon dioxide are important refrigerants, especially in the food industry, where they are employed during the transportation and storage of ice cream and other frozen foods. Solid carbon dioxide is called "dry ice" and is used for small shipments where refrigeration equipment is not practical. Solid carbon dioxide is always below −78.5 °C at regular atmospheric pressure, regardless of the air temperature. The global automobile industry is expected to decide on the next-generation refrigerant in car air conditioning. is one discussed option.(see
Carbon dioxide laser the gas for their products. The table below illustrates the output range from nine possible isotope combinations: Because of the high power levels available (combined with reasonable cost for the laser), CO lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. It is also used in the additive manufacturing process of Selective laser sintering (SLS). Carbon dioxide lasers have become useful in surgical procedures because water (which makes up most biological tissue) absorbs this frequency of light very well. Some examples of medical uses are laser surgery and skin
