Energy Core (Draconic Evolution)

The Energy Core is a machine added by Draconic Evolution energy storage system. It is the central part of the Energy Core multiblock which can store massive amounts of Redstone Flux (RF). This structure comes in 8 tiers.

Usage
When fully assembled, RF can be introduced to and extracted from the structure through the use of Energy Pylons. These can be placed anywhere within 16 blocks of the Core, and are activated by placing a block of Glass either above or below the Pylon (depending if it is below or above the Core, respectively), which will turn into a blue orb. Pylons can be toggled between input and output mode by right clicking the orb, and can move 2,147,483,647 RF/t per face.

The amount of RF that can be stored inside an Energy Core of a given tier is:

Construction
Right-clicking the Energy Core opens an interface to select an Energy Core tier and enable a building guide. Energy Core Stabilizers need to be placed at each cardinal point around the Core, vertically or horizontally as long as it's on the same plane, up to 16 blocks away from the Core.

Energy Core tier 5 and above instead require Stabilizers to be placed in a 3x3 square at each point instead.

Tier 1
The structure is 1x1x1 (not counting the Stabilizers) and requires (on top of the Core):
 * 4 s

The structure consists solely of the Energy Core block.

Tier 2
The structure is 3x3x3 (not counting the Stabilizers) and requires (on top of the Core):
 * 4 s
 * 6 s

Tier 3
The structure is 3x3x3 (not counting the Stabilizers) and requires (on top of the Core):
 * 4 s
 * 26 s

Tier 4
The structure is 5x5x5 (not counting the Stabilizers) and requires (on top of the Core):
 * 4 s
 * 54 s
 * 26

Tier 5
The structure is 7x7x7 (not counting the Stabilizers) and requires (on top of the Core):
 * 36 s
 * 90 s
 * 80

Tier 6
The structure is 9x9x9 (not counting the Stabilizers) and requires (on top of the Core):
 * 36 s
 * 150 s
 * 178

Tier 7
The structure is 11x11x11 (not counting the Stabilizers) and requires (on top of the Core):
 * 36 s
 * 210 s
 * 328

Tier 8
The structure is 13x13x13 (not counting the Stabilizers) and requires (on top of the Core):
 * 36 s
 * 786 s
 * 378 s
