L5 Scenario in a Nutshell

The diagram below is from NASA Publication SP-413, Space Settlements: A Design Study.  Here is a quote from page 175:  “An upper limit to the speed of growth of space colonization is estimated by assuming 3 years for the duplication of a habitat by a workforce equivalent to 12 percent of a habitat’s population. Only 56 years are required at this rate for the construction of communities in space adequate to house a population equal to that of the Earth today.”
