IMPORTANT : The game has been patched since this video and some of the mechanics like steam turbines have been changed. Below is a link to an updated tutorial from 11/10/2019 https://www.youtube.com/watch?v=pbi-KidPQKA
In this tutorial we tackle Rockets using steam rockets to get us to Petroleum and oxylite. Then
using petroleum to get to liquid oxygen and hydrogen.
EDIT: You can use the metal refinery to convert Thermium to niobium at 100% efficency, thanks to
Orion Egenes and Alrion1704 for pointing this out. Please note Tungsten is finite you should only really do this if niobium is very difficult to obtain and only enough to get Liquid oxygen/hydrogen up.
