Large Essentia Generator

Large Essentia Generator

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 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

Large Essentia Generator Overview

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 which cannot be mixed in the multiblock structure. 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 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. They cannot be mixed.

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 8 categories: Radiation, Sprite, Mechanics, Tainted, Victus, Unstable, Thermal, and Air. The upgrades' names are formatted as "Essentia Generator: [Category]" (i.e., Essentia Generator: Thermal). Installation of the upgrade is done by right-clicking the controller with the upgrade, and multiple upgrades can be applied to a LEG.

Warning: the installed upgrade is not displayed anywhere, the message in chat is only displayed during installation, and upgrades cannot be retrieved or removed.

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.

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

${\frac {{\text{Fuel Value}}\times {\text{Fluid Efficiency}}\times {\text{Stable Point}}}{25}}$

The formula for fluid drained per essentia is

${{\text{Category Fluid Volume}}\times {\text{Essentia (Drain) Coefficient}}}$

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.
