Minecraft Joules

A Minecraft Joule, MJ for short, is an energy unit introduced by BuildCraft. It is used to power different machines, also introduced by the same mod, and is measured in MJ per tick, or MJ/t.

What Other Mods Use MJ?
Many different mods use this as their energy type as well. Below is a list of these Mods.

Producing MJ
MJ is produced by s of varying types. Each engine will produce a different amount of MJ and will require either a Redstone Signal or fuel and some kind of cooling. Some engines will explode if not provided with adequate cooling.

BuildCraft Engines
BuildCraft Engines are listed below. It can take a little while for these engines to warm up and produce their full output power.

Transporting MJ
In order to make use of MJ you will need to transport it where it is needed. Each Mod has its own MJ transport system.

BuildCraft Kinesis Pipes
BuildCraft uses a type of Kinesis Pipe called s. Each pipe type can transport only a certain amount of MJ. Only s can extract MJ from an engine. After that another type of Kinesis Pipe will be required.
