CO2 Backstory 1.1
Carbon Dioxide (CO2) is Universal
Abundant and Natural
Carbon dioxide (CO2) is an abundant, natural, and renewable manufacturing resource. To begin with, you are a CO2 production plant. Shown in Figure 1-1, with each breathe of air, comprising about 78% Nitrogen (N2) and 21% Oxygen (O2), you expire a small amount of CO2 gas along with unused N2 gas, water vapor (H2O), and organic (carbon-based) vapors as metabolic by-products. Over the course of a day, you produce about 2.3 lbs. of gaseous CO2 [1]. This equates to filling a little over two 16 ounce water bottles with liquid carbon dioxide each and every day. Over a year, you fill nearly two 55 gallon drums. Over your lifetime, you will fill more than fifteen average-sized hot tubs – about 8,000 gallons of liquid CO2!
