BuildCraft

BuildCraft is a mod that uses machines to mine resources, craft items, and sort resources. It also has machines that can automatically build structures based on blueprints. The mod also includes pipes to transport items, liquids and power.

The BuildCraft machines are run with by a new type of energy, Minecraft Joules (MJ), and three engines can produce this energy: the Redstone Engine, Stirling Engine, and Combustion Engine. There are also other mods such as Thermal Expansion, Forestry, and Railcraft that add new engines to the game, e.g. the Electrical Engine that converts IndustrialCraft 2 power (EU) into BuildCraft power. BuildCraft introduces two new liquids, oil and fuel, to provide increased energy output. The BuildCraft Wrench is a new tool to reorient machines and piping systems.
