Thunder Stone - Basic Thorium and Rare Earth Mod (Initial Alpha)
I saw that there was a uranium mod already out there, and since thorium > uranium in every way bar atomic number, I decided to make a thorium mod.
Features
New ore: monazite, rarer than copper but not as rare as oil. Bright green in Factorio. Not bright green in real life (proving that, if there is a Creator, he/she/it can be boring sometimes).
Two new metals: Thorium and Rare Earth, both obtained by combining monazite ore and sulphuric acid in a chemical plant. Note: monazite cannot be smelted.
Thorium reactor: specifically a liquid fuel thorium reactor. Acts as a boiler by converting liquid thorium fuel (made from thorium metal and water) and normal water to produce boiling water, which can then be used in steam engines. Thorium reactors do not produce any pollution.
Rare earth: Advanced Circuits and Processor Units now require 1 rare earth metal plate each.
The thorium reactor, along with the monazite/thorium processing recipes, are unlocked with the Thorium Processing technology, which requires 100 red and green science packs and prior knowledge of Fluid Handling.

Credit to Klonan for the oil steam boiler that forms the basis of the thorium reactor, and to DaveMcW for pointing me in the direction of Klonan's resource at the crucial moment.
