When touching items with physical characteristics, the block will be connected with celesthium and send celesthium energy to nearby blocks of the same kind.
By storing specific items with physical characteristics, it can only detect stored items.
You can use a Wrench to switch the mode into vehicle trigger mode, where only machines will be detected. Also, the team information will be sent with celesthium signals.

This block cannot be crafted in Survival and can only be obtained by taking it out of the bag in Creative mode or using a trigger or script. (version 1.4.41)
