The tesseract's main building works as both an accumulator and as a large chest but it uses the excesses energy to generate shards these shards contain a large amount of energy and are used to make extensions of the tesseract
Pylons are a kind of accumulator that is linked to the tesseract's internal reserves they will send energy to the tesseract when full and retrieve it when empty, they also increase the internal reserves
Teleporter chests retrieve requested items from the tesseract and send everything else back, there's 2 ways to request items from it. 1 you can set a filter inside the chest and the tesseract will try to fill it with the requested item, 2 you can send a signal to the chest with the type and amount need and the tesseract will send them, they will also increase internal storage capacity
Teleport tanks are similar to the teleporter chests but for fluids, it is controlled by circuits just like the teleporter chest and will also increase the storage
Data proxy is the way to see what is inside the tesseract, it will send signals for each item or fluid inside, and it also shows the stored energy the max storage capacity, etc
