Applied Energistics 2 (AE2)

Applied Energistics 2 is a mod that focuses on creating a compact, easily accessible, considerably extendible storage system called an ME Network. The "ME" in the title stands for "Matter <-> Energy" -- the premise being that items added to the system are converted into energy and stored in a digital form before needing to be used again, whereupon they are converted back into matter. The first and utmost block to build and power a Network from is the Energy Acceptor, since the mod doesn't generate it's own energy, the Acceptor will convert energy from most mod's generators to AE units needed to power the Network devices.

Channels
Channels are a major mechanic added by the mod. Most, but not all devices in the network will use a channel to function. Devices without access to a channel will not function as if not connected and some will show a light purple status instead of blue. An ME Controller connected with ME Dense Cable is required to expand the Network beyond 8 channels, the transmission capacity of any other network cable.

Using Dense Cable, each side of an ME Controller can transmit up to 32 channels distributed via a main line and branching off with other types of cable to the Player's preference for a total of 160 channels per Controller. Furthermore, since the ME Controller can be a multiblock structure, it is possible to expand this capacity greatly by connecting cable to each controller block. And when using directly-connected P2P Tunnel - ME, more compact designs become available, running up to 128 channels off of one smart cable!

ME Auto Crafting
The Auto Crafting system is a major feature of the mod and has been completely overhauled. It's a very convenient way of crafting items on demand as it is needed, the system automatically craft all the necessary parts for the job placed, as long as the resources are available. The Player only need to assemble the recipe once and save it to the system. These ready to craft items do not use any storage space.
