Steam Dynamo

This page is outdated. It will soon be updated or rewritten to match the latest version of the mod.

This version of the page will remain available here.

The Steam Dynamo is one of the Dynamos added by Thermal Expansion. It generates Redstone Flux from Steam. Steam can be pumped in from external sources, but it can also be generated internally using Water and solid fuels.


Shaped Crafting


The Steam Dynamo generates energy from Steam at a ratio of 2 RF per mB. It only generates if 2000 or more mB of Steam is stored in the Dynamo's internal tank. When not generating, any Steam stored in the Dynamo is gradually lost.

Steam may be pumped into the Dynamo from external sources. The Steam Dynamo can also internally convert Water into Steam using solid fuels. In this case, Water must be pumped in or put in manually using Buckets. Aqueous Accumulators can be used to easily produce Water for this.


The Steam Dynamo generates energy at a maximum rate of 80 RF per tick. This rate may decrease depending on how full the Dynamo's internal storage is, which may fill up if the Dynamo cannot emit its energy. The rate may be reduced down to a minimum of 8 RF per tick. At this point, generated energy that cannot be stored anywhere is lost.

Installing the Excitation Field Limiter Augment removes this lower limit, allowing the Dynamo to automatically stop generating energy completely if needed.


Energy generated by the Steam Dynamo is stored in the Dynamo's internal energy storage. It is then emitted as soon as possible in the direction in which the Dynamo's red coil is pointing. The Dynamo does not emit energy if it is inactive, even if some generated energy is still stored in it.

The Dynamo accepts Steam, Water and fuel items from external sources like Machines or Ducts. These can be inserted on all sides of the Dynamo, except for the coil. However, if the Transmission Coil Ducting Augment is installed, that side may also receive them.


The below table lists the items that can be used as fuel for producing Steam internally. It displays how much energy the Dynamo can generate from each kind of fuel. Items that yield less energy are used up more quickly.

Keep in mind that the Dynamo does not generate energy if less than 2000 mB of Steam is stored in its internal tank. Burning a piece of fuel will therefore not always yield the full amount of energy, as Steam is produced from burning fuel and then consumed to generate energy.

Fuel Max. Energy
Furnace fuels** (items smelted × 3000) RF
Coal 24000* RF
Block of Coal 240000 RF (10x Coal)
Charcoal 16000* RF
Wooden blocks 3000* RF
Stick 1000 RF (Wooden blocks / 3)
Sapling (vanilla Minecraft only) 1000 RF (Wooden blocks / 3)

*: May be changed in the config.
**: Wooden tools, Lava Buckets and Blaze Rods cannot be used in the Steam Dynamo. For generating energy with the latter two, use the Magmatic Dynamo.


1. Steam Tank
Steam that is to be consumed for generating energy is stored here. Slowly drains if the Dynamo is inactive.
2. Water Tank
Water that is to be heated into Steam using fuel items is stored here.
3. Fuel Slot
Items placed in this slot are consumed as fuel to produce Steam.
4. Fuel Gauge
Displays the progress of the fuel item currently being burned.
5. Energy Gauge
Displays how much Redstone Flux is currently stored in the Steam Dynamo's internal energy storage.
6. Energy Tab
Displays how much power the Steam Dynamo is generating, and how much Redstone Flux is currently stored in it.
