Singleblock Generators

Singleblock Generators consist of only one block and generate power for other machines. They are only available in a few tiers each and always have less throughput and efficiency than their multiblock equivalent, if one exists. They are also not easily upgradeable since they output a fixed voltage tier and must be fully replaced when necessary. However, they are still required to progress through the early game and some are even useful throughout the entire game, such as for generating power on other planets or in other dimensions.

The input of fuel and output of energy is nearly universal amongst GregTech singleblock generators. There is only one output side for extracting power (indicated by a dot) and the remaining sides are all valid locations for inputs or covers. Right-click with a wrench to change the direction of the output side.

The following are all the singleblock generators in GTNH, organized by type. Most are only available at a few tiers and a few have their own individual pages because they are too complex to describe in full detail here. Singleblock Machines also have their own page.

The internal storage of a singleblock generator is always a single tank or item slot and their output is always 1A of power at their rated voltage. Their efficiency is a multiplier that scales the input fuel density. For example, creosote oil has a base fuel density of 48 EU/L but an efficiency of 50% reduces that to only 24 EU/L, meaning twice the amount of creosote oil would be needed for the same amount of power. Singleblock generators also have a built-in loss based on their voltage and consume extra fuel to cover it, as seen in the following table and equation.

${\displaystyle {\displaystyle {\text{Fuel Consumption (L/s)}}={\frac {20\times ({\text{Output EU/t}}+{\text{Loss}})}{{\text{Efficiency}}\times {\text{Fuel EU/L}}}}}}$

Singleblock generators do not consume excess fuel if their internal EU buffer is full which means there is no consequence for leaving excess fuel inside of them during periods of low power consumption, unlike their multiblock equivalents. The fuel consumption rates in the following subsections are all per second for consistency but technically singleblock generators consume half the fuel every 10 ticks instead. Divide the EU/s values by the EU/L values to find the specific fluid rates in L/s, or use the planner linked at the top. The most common fuel options are highlighted BLUE.

Singleblock steam turbines are available in three voltage tiers with decreasing fuel efficiency. Steam is the only valid fuel and has a base density 0.5 EU/L. Singleblock steam turbines are superseded by the Large Steam Turbine.

Singleblock gas turbines are available in five voltage tiers with decreasing fuel efficiency. The available gas fuels and their densities are listed below in the following table. Singleblock gas turbines are superseded by the Large Gas Turbine and the Solid-Oxide Fuel Cell.

Singleblock combustion generators are available in five voltage tiers with decreasing fuel efficiency. The available diesel fuels and their densities are listed below in the following table. Singleblock combustion generators are superseded by the Large Combustion Engine, Extreme Combustion Engine, and Universal Chemical Fuel Engine.

Singleblock semifluid generators are available in five voltage tiers with decreasing fuel efficiency. The available semifluid fuels and their densities are listed below in the following table. Singleblock semifluid generators are superseded by the Large Semifluid Burner.

Singleblock acid generators are available in five voltage tiers with decreasing fuel efficiency. The available acid fuels and their densities are listed below in the following table. Singleblock acid generators are superseded by the Large Neutralization Engine.

Singleblock magic energy converters are available in three voltage tiers with decreasing fuel efficiency. Some of the most common magic fuels and their densities are listed below in the following table. Blood Magic slates are not fully consumed in the process and returned one tier lower. Magic energy converters do not have a multiblock equivalent but they build into magic energy absorbers which have slightly more functionality.

Singleblock magic energy absorbers are available in four voltage tiers with decreasing essentia efficiency. They do not consume fuel like the magic energy converters and instead draw power from nearby magical sources such as dragon eggs, creeper eggs, or energised nodes. Right-click with a screwdriver to adjust their range as necessary. Enchanted items are returned unenchanted. Magic energy absorbers do not have a multiblock equivalent.

Singleblock lightning rods are available in three voltage tiers. They do not consume fuel and only generate power when struck by lightning during thunderstorms. Stack up to 5 iron fences on top to increase the probability of lightning strikes and therefore its average power output. Each lightning strike adds 50M EU to the lightning rod's internal buffer, but 1% of the current EU is loss per tick so it must be extracted as quickly as possible. Every side other than the top is an output and collectively provide up to 512A of power. Lightning Rods do not have a multiblock equivalent.

Singleblock geothermal engines are available in three voltage tiers with decreasing fuel efficiency. The available geothermal fuels and their densities are listed below in the following table. Pahoehoe Lava and regular lava can both be supplied in their liquid form or in a cell, but the cell is consumed in the process so that is not recommended. Singleblock geothermal engines do not have a multiblock equivalent, but lava can be used in a heat exchanger to generate steam for Large Steam Turbines.

Singleblock rocket engines are available in three voltage tiers with decreasing fuel efficiency. The available rocket fuels and their densities are listed below in the following table. The pollution varies signficiantly because it is randomly sampled from a uniform distribution every 10 ticks. Singleblock rocket engines are superseded by the Rocketdyne F-1A Engine and the Universal Chemical Fuel Engine.

Singleblock kinetic generators are available in five voltage tiers and two types. The water generator produces a fixed amount of mechanical energy (KU/t) while fully submerged in water in either a river or ocean biome. The wind generator produces a variable amount of mechanical energy (KU/t) from winds between y=64 and y=160. Both require an IC2 rotor to run and an equivalent kinetic generator to convert KU/t into EU/t. Different rotors have different lifespans and efficiencies, as seen in the following table. Kinetic generators do not have a multiblock equivalent.

Singleblock plasma generators are available in five voltage tiers with increasing fuel efficiency. The available plasma fuels and their densities are listed below in the following table. Singleblock plasma generators are superseded by the Large Plasma Turbine.

Singleblock naquadah reactors are available in five voltage tiers with increasing fuel efficiency. The available naquadah fuels and their densities are listed below in the following table. Only two specific fuels are allowed in each one. Singleblock naquadah reactors are indirectly superseded by the Large Naquadah Reactor.

Singleblock solar panels are available in eight voltage tiers. They do not consume fuel or produce pollution, but they require direct sky access and do not generate power at night or in the rain. The Personal Dimension is the ideal place for solar panels because it offers permanent daylight and perfect weather. All eight tiers require a Solar Factory to craft and use superconductor (sc) wire from 1-3 tiers above. Solar panels do not have a multiblock equivalent, but they are later used to craft casings and field generators for the Eye of Harmony.

Singleblock compressed solar panels are available in eight voltage tiers. They do not consume fuel or produce pollution, but they require direct sky access and do not generate power at night or in the rain. However, they can be infused with any of the six primal aspects to change their behavior and generate additional amps, as seen in the following table. All eight tiers require progression in Thaumcraft to craft and have no direct recipes--they always require multiples of the previous tier. Compressed solar panels do not have a multiblock equivalent.

• The EnderIO weather obelisk can be used to create a permanent thunderstorm for Lightning Rods and Aqua compressed solar panels. Thaumcraft Warp also ocassionally generates a thunderstorm that only goes away after sleeping.
