MJ=MinecraftJoule (I knew, I didn't copy)

The MJ is the equivalent of the J (Joule) from reality. In reality, it defines a force. I don't remember exactly the measures.

In the Minecraft, MJ can be produced by engines and is consumed by BC machines (eg. refineries). It is transported by conductive pipes. You can convert EU (from IndustrialCraft) to MJ with the Energy Link or MJ to EU with engine generators (be careful what voltage you want!).
