TechnicCraft

Players start by producing energy from a Coal Generator, which burns coal, or an Oil Generator, which uses oil found in lakes generated throughout the world. Milling Machines and a Precision Milling Machine turn raw materials into parts, and the mod adds a wide variety of blocks such as the Battery and the Coal Generator. Three new structures are placed around the world: a Factory with an early-game boost, a Crashed Rocket holding advanced items and mechanisms, and a Laboratory with useful materials.

The Nuclear System is the most involved part of the mod. Uranium Ore appears in common underground caves and is milled into Yellowcake, which a Uranium Refinery turns into Depleted Uranium and then Enriched Uranium. A Nuclear Reactor using Enriched Uranium and Cold Water produces large amounts of energy, and that water needs a new Cooling Plant block. Enriched Uranium also feeds a Nuclear Bomb with a tremendous explosion power useful for underground mining operations.

Installation needs only Forge, and the mod runs on the client and the server, so both need it. TechnicCraft is published for 1.18.2 with a latest Forge file of 0.8.3 on the beta channel, and it is released under All rights reserved, so it is not open source.
