Reactant Dynamo


Reactant Dynamo

A reactant dynamo is a dynamo fueled by fluid fuel and solid reactant.

Obtaining

A placed reactant dynamo can be instantly picked up by dismantling it with a wrench. Its configuration is preserved in the item. It can also be mined using a pickaxe, though this can be much slower.

Crafting

Upgrading

A reactant dynamo is initially at the lowest tier (basic). It can be upgraded to higher tiers using upgrade kits and conversion kits.

Usage

Placement

When placed, a reactant dynamo faces up. When placed while sneaking, it faces away from the player. A reactant dynamo can face any direction, and can be rotated using a wrench.

Energy generation

When a reactant dynamo is supplied a fluid fuel and a reactant item that can react with one another, the dynamo will start consuming both to generate Redstone Flux. 100 mB of fluid fuel and one unit of reactant are consumed together at a time. Every reaction yields a certain amount of energy.

The speed at which energy is generated and fuel and reactants are consumed depends on how much power can be emitted, and on the dynamo’s maximum power output. A basic reactant dynamo has a maximum power output of 40 RF/t. This can be increased by upgrading the dynamo to a higher tier, and by installing certain augments.

When an active reactant dynamo cannot emit the energy it generates, it will keep working at its minimum power output (a tenth of its maximum power output). Any more energy that is generated in this case is lost. This can be resolved by installing an excitation field limiter.

Input and output

A reactant dynamo emits Redstone Flux from its coil, which points in the direction the dynamo is facing. It only emits energy when it is active. Fluids and items can enter a reactant dynamo through its sides. They cannot enter it through the coil, unless transmission coil ducting is installed.

Redstone control

A reactant dynamo may be configured to respond to redstone signals. It can be in one of three modes:

Ignored
Redstone control is disabled. The dynamo works whenever possible. This is the default mode.
Low
The dynamo works when not powered. When powered, it stops working.
High
The dynamo only works when powered.

The current mode can be set using the Redstone Control tab in the dynamo’s GUI.

When a reactant dynamo is deactivated by a redstone signal and is still generating energy from a reaction, it will finish generating energy from that reaction first.

Security

A reactant dynamo can have a signalum security lock installed to restrict who can access it.

Redprints

A reactant dynamo’s configuration can be saved on a redprint to be copied to other dynamos.

Light source

When a reactant dynamo is active, it emits a light level of 7.

Tiers

Reactant dynamos come in six tiers.

TierMax. power outputAugment slots
Basic40 RF/t0
Hardened60 RF/t1
Reinforced80 RF/t2
Signalum100 RF/t3
Resonant / Creative120 RF/t4

Augmentation

A reactant dynamo can have augments installed to improve certain properties or to change how it works. The amount of augments that can be installed depends on the dynamo’s tier. A basic reactant dynamo cannot be augmented.

Augments can be installed in the Augmentation tab in a reactant dynamo’s GUI.

AugmentInstallable inDescription
Augment: Auxiliary Transmission CoilAuxiliary Transmission CoilAny dynamoIncreases a dynamo's maximum power output (speed). Can be installed multiple times.
Augment: Fuel CatalyzerFuel CatalyzerAny dynamoIncreases the amount of energy a dynamo generates from each unit of fuel. Can be installed multiple times.
Augment: Transmission Coil DuctingTransmission Coil DuctingAny dynamoAllows items and fluids to enter a dynamo through its coil, which can normally only emit energy.
Augment: Excitation Field LimiterExcitation Field LimiterAny dynamoLowers the minimum power output of a dynamo to zero, preventing energy loss when it is active and cannot emit the energy it generates.
Augment: Elemental CatalyzerElemental CatalyzerReactant DynamoA specialization that greatly increases a reactant dynamo's maximum power output and the amount of energy it generates from each reaction. However, the dynamo can only generate energy from elemental reactions, like between blazing pyrotheum and cryotheum dust.
