Minecraft Joules

A Minecraft Joule (MJ) is an energy unit introduced by BuildCraft. It is used to power different machines also introduced by the same mod as well as others (including Forestry and Railcraft).

Producing MJ
MJ is produced by s. 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 the player will need to transport it where it is needed. Each mod has its own MJ transport system.

BuildCraft Kinesis Pipes
BuildCraft uses s to transport MJ. Each pipe type can transport only a certain amount. Only s can extract MJ from an engine; after that other types of Kinesis Pipe will be required.
