Frivolously Unofficial Content is an addon mod for GregTech CE: Unofficial that is meant for use attached to the Frivolously Unofficial Modpack.

Adds significant mid-endgame content, mostly revolving around multiblocks. Designed to work in tandem with CraftTweaker scripts provided by the modpack, but is fully standalone.

Multiblocks Added:

Fusion Stacks

Find yourself with too many fusion reactors dedicated to one product? Ever wanted to build a multiblock as large as a factory? With Fusion Stacking, continue scaling your fusion production past the first three reactors! With the Fusion "Stack", Fusion "Array", and Fusion "Complex", you can bulk fusion with one machine and save on costs. Every tier of fusion stack has the production capabilities of four of the previous, while only costing somewhat more than two of the previous.

Linear Forging Furnace

Who needs production lines? Through the power of the Linear Forging Furnace, go straight from ingredient to worked metal in a single multiblock. This does come with some energy and time penalties, but the LFF has a customizable structure, allowing it to simply act as both EBF and ABS in one and provide parallels, though this can be very expensive on coils.

Heat Exchangers

Get more bang for your plasma buck with an extended processing method. Instead of just throwing plasma into a turbine, instead pass it through a heat exchanger to get the heat out of it. This heat can then be used in another heat exchanger to boil water, which produces far more power in a turbine than the original plasma would have.

Heat Reclaimers

Make muffler hatches great again with the Heat Reclaimer! By placing one of these over a muffler hatch, heat is reclaimed based on the power the hatch's parent multiblock is expending/producing, the muffler hatch tier, and the reclaimer tier. This heat can then be used to boil water directly, or be passed through a Heat Exchanger instead.

Disclaimer: the Heat Reclaimer doesn't work on steam generators because duh.

Heat Disperser

Have a hot liquid and would prefer it if it weren't hot, but can't be bothered to build a full heat exchanger steam turbine loop? The Heat Disperser can cool things down (or heat things up) towards room temperature for a much lower initial cost than a heat exchanger setup, but you can't extract power from the cooling like with an exchange setup.

Sympathetic Combustor

Find yourself with ten different burnable fuel variants on hand and seeking ever-higher efficiency gains? Presenting the Sympathetic Combustor, a generator with vast efficiency potential (at a cost). Every unique burnable fuel, be it solid, liquid, or gas provided to the combustor boosts its fuel efficiency exponentially. The more balanced the fuels, the higher the efficiency.

Large-Scale Industrial Steam Engine

For those who mourn how useless the Industrial Steam Engine is, well now it's back. And large. Designed to deal with the vast quantities of steam produced by plasma heat exchange, this multiblock sacrifices turbine efficiency bonuses for raw output strength: a single one, if provided with enough steam, can produce up to 256 amps of UHV power.

Naquadah Reactors

While the concept of naquadah reactors might be familiar due to its implementation in other modpacks, the reactors provided by FuContent have a noticeably different implementation, despite sharing the name.

Pneumatic Infuser

The workhorse of the addon's multiblocks, the Pneumatic Infuser is used for quite a few new recipes.

Electrode Smelter

Have you ever wanted an ABS that supports parallel recipes? Look no further than the Electrode Smelter, a thicc RHF that supports both EBF and ABS recipes depending on the mode.

Infinity Extractor

The tamest multiblock. This modest machine extracts fragments of infinity from bedrock, which are used in several new recipe lines.

Star Siphon

With the power of Project E and EX on your side, you'll probably be swimming in EMC by the endgame. And here is an infinite chasm ready to devour it all. Accepting klein stars, magnum stars, and colossal stars, this one multiblock produces enough plasma to rival a real star. Each tier of emc star produces twice as much plasma per operation at four times the EMC cost, so picking the right star tier for your needs is critical.

Antimatter Compressor

The addon's final multiblock. Within an impenetrable crucible, reactions driven by matter inversion and annihilation break past the boundaries of physics and achieve the infinite.

Features Added:

Dimension Breathability

Have you ever thought to yourself in the nether, "Wait, how is Steve breathing carbon monoxide without dying?" Well, worry not, Steve can't anymore. Both the nether and the end have a toxic atmosphere, and the end is even radioactive! Gas masks and GT armors will protect you from these deadly effects. For those who enjoy tweaking, all dimension breathability restrictions are completely configurable to your heart's content.

Endgame Content

For those who have reached the end of gregtech, you've probably made yourself an ultimate battery. Remember the tooltip? "Fill this to win Minecraft". Well, now that's the final challenge. Through the help of the addon's new multiblocks, some new recipe lines, and a whole bunch of grinding, it is now realistically possible to obtain a 100% full ultimate battery. (We're not Avaritia though, it's not that bad.)

Alternate Trinium

Through a new, direct recipe line using the addon's multiblocks, obtain trinium in large quantities.
