IDSU

The Interdimensional Energy Storage Unit is a storage device for EU added by GregTech, and the most advanced in the game. It has a capacity of 1,000,000,000 EU. It's input is 2,048 EU/p and it's outputs packages of 2,048 EU/t. Unlike other EU storage devices, the IESU links to other IESU, like an enderchest, but for EU. This is the only way to teleport EU. This also means EU isn't lost when the IESU is broken.
