Zero Point Module (GregTech 5)/en

The Zero Point Module, or ZPM, is a tier 7 (ZPM-Tier) single-use battery capable of providing 2 trillion EU added by. It cannot be crafted; it can only be found, very rarely, in dungeon chests located within Jungle Temples. It is useless once it has been depleted, but it takes almost 212 hours to deplete it at its maximum discharge rate. The ZPM is a significant enough item that it has its own voltage tier named after it.

Trivia

 * A Zero Point Module is an item originally featured in the science fiction franchise Stargate. It most notably plays a key role in the TV series Stargate Atlantis, as the show’s central location, the city ship Atlantis, uses ZPMs as the main power source.
