Large Essentia Generator Overview

The Large Essentia Generator (LEG) is a multiblock power generator added by the Good Generator mod crafted in EV tier that consumes certain types of Thaumcraft essentia to generate power. There also exist several upgrades which allow the LEG to consume external fluids to boost the efficiency of some types of essentia or allow some previously unusable kinds of essentia to be consumed.

Research

The research for the LEG can be found in the Artifice tab of the Thaumonomicon, with the Artifice: Infusion parent research.

Multiblock Structure

LEG Layer 1: Hatches can replace any Magic Casing in the centered plus shape.
  1. Layer 1: Consists of Magic Casings and Arcane Stone Bricks. Fluid Input Hatches, Essentia Input Hatches, Maintenance Hatches, and Dynamo Hatches can replace any of the magic casings in the middle plus shape on this layer.
  2. Layer 2: Consists of a ring of Magic Casings and Essentia Diffusion Cells, and Arcane Stone Bricks on the outer pillars. Essentia Diffusion Cells come in four different tiers and can be mixed. See the Essentia Diffusion Cells section below.
  3. Layer 3: Consists of the controller block on the top center, and Amber Bricks on the outer pillars.

Essentia Diffusion Cells

The minimum tier of the Essentia Diffusion Cells dictates the maximum Dynamo Hatch tier the LEG can accept. Higher tiers also improve efficiency via the StablePoint mechanic. The total stable value of a LEG is the sum of the StablePoints contributed by each Diffusion Cell.

Essentia Diffusion Cell Tier Dynamo Hatch Tier StablePoint
Novice EV 1
Adept IV 2
Master LuV 5
Grandmaster ZPM 10


Upgrades

The optional LEG upgrades allow the LEG to consume external fluid to boost the EU value of some essentias or allow them to be consumed at all. These essentias come in 9 categories: Radiation, Spirit, Mechanics, Tainted, Victus, Unstable, Thermal, Air, and Electric. The upgrades' names are formatted as "Essentia Generator: [Category]" (i.e., Essentia Generator: Thermal). Installation of an upgrade is done by right-clicking the controller with the upgrade, and multiple upgrades can be applied to a LEG.

Liquid is optional for Victus, Tainted, Spirit, and Radiation, and not used in Electric.

Warning: any installed upgrades are not displayed anywhere, a message in chat is only displayed during installation, upgrades cannot be retrieved or removed, and breaking the controller voids all upgrades.

Essentia Input

Before running the LEG, the Essentia Input Hatch must be attuned to the desired essentia. This can be done by right clicking the Essentia Input Hatch with a phial filled with that essentia. The Thaumcraft Essentia Resonator can check if the attunement was successful. Essentia can be provided using either Essentia Tubes or the Thaumic Energistics Essentia Provider.

Tainted Upgrade Mechanics

Using the essentias and fluids in the Tainted category is supposed to cause flux gas pollution around the LEG. The volume spawned is a random fluid level from 0-8. The spawn chance per essentia consumed is dependent on the fluid used.

Fluid Flux Gas Spawn Chance per Aspect Consumed
None 20%
Purifying Fluid 0%
Liquid Death 40%

However, this behavior is currently bugged and the LEG will attempt to spawn the flux gas at a random coordinate in the range x=0-4, y=0, z=0-4 wherever there is open air; in the overworld, this will likely fail due to the presence of bedrock at y=0.

Output

The LEG will always try to output the highest voltage it can at 1A before outputting more amps.

As of 2.6.1 (drawn from GitHub, GT5U repository):

The formula for EU generated per essentia is

The formula for fluid drained per essentia is

The Thaumonomicon entries gives an incorrect basic consuming speed in a rate of seconds; in reality, fluid consumption is proportional to essentia consumption (the "Upgrade your generator" entry also does somewhat imply this). The source code instead has "Category Fluid Volumes" that are the fluid consumption rates in the Thaumonomicon divided by 20.

  • Fluid Efficiency: higher is better
  • Category Fluid Volume: lower is better
  • Drain Coefficient: lower is better
