Space Structures by James McLellan

This is my first stab at a Tiddly Wiki book. It’s available for Pay What You Want at DriveThruRpg

Using @BurningTreeC 's multi-column layout, this tries to be a resources first as a game to people who might want to play, but also to sci-fi creators in general who often want to sanity check if ideas are “realistic”. Powering the performance evaluations of an extensive list of sci-fi equipment are TiddlyScript libraries for heating and cooling, radiation, signal attenuation, and orbital mechanics.

Thank you very much, @jeremyruston for an awesome freaking tool, @BurningTreeC for the multi-column library, and everyone here who tolerated stupid questions!
