Public Domain: A Sheltering Fire

A Public Domain Scifi Setting: A Sheltering Fire. The O'Neil cylinder colonies have ventured into interstellar space in pursuit of the Sunmaker which collects interstellar hydrogen with its electromagnetic scoop directing this flow of protons into three dee printers which assemble artificial stars that are ejected during its transit to Proxima.
The colonies are able to warm themselves along the colony trail...on their long journey.

Enjoy.
