Thermal Conversion
by stuin
Thermal Conversion is a Fabric technology mod that converts solid fuel into energy, so furnace-style machinery can run on it instead of the usual coal-type generator inputs.
What it does
Thermal Conversion brings Universal Energy Translation to the basic furnace mechanics. Players start by crafting a Thermal Cell, then collect enough cells to compress them with the same arrangement used for a chest. The compressed result lets the energy system support smelting, so a machine can convert solid fuel into power.
The mod covers the typical coal-type generator role and is meant for players who move between technology mods. The author notes that lava loses some energy in the process, since it only smelts 100 items per use, and considers the trade worth it for many applications. The mod is installed on the client and the server, and the build is published for Fabric and 1.17.1 only, under All rights reserved, so it is not open source.
Key features
Universal energy translation
Furnace mechanics are extended so that solid fuel can feed the energy system instead of only smelting items.
Thermal Cell crafting
A Thermal Cell is the first craftable step, and collected cells can be compressed with the same chest-style arrangement.
Fuel-for-smelting conversion
The energy put in is matched to the number of items a fuel can smelt, which sets how much fuel each conversion uses.
Lava smelting trade-off
Lava loses some energy when it smelts, because it only smelts 100 items, a cost the author accepts for many uses.

What the author says
Thermal Conversion allows you to take any energy system that supports smelting and convert into solid fuel, allowing you to move it into any other typical coal type generator. Once you pick up enough thermal cells, you may compress them using the same formation as with a chest or furnace.
