Just curious if it is intended for it to be possible to get infinite Iron.
It is fairly simple to do, just need a cobble-gen feeding into a pulverizer/furnace combo to make glass. The glass is then made into glass bottles in a cyclic assembler. The bottles are passed through a fluid transposer then passed to a Chemical Decomposer to make H2O. H20 can then be turned into water buckets that are then emptied in another fluid transposer, feeding the water back into the system. The buckets are then Decomposed and reconstituted into ingots.
Imgur album of the setup.
Haven't tested to see how much energy this uses, but with solar its not much of an issue anyways.
I know infinite iron isn't that hard to do with an Iron Golem farm, but not needing to insert anything other than cobble and water for iron just feels a bit cheaty.
Using H2O to make buckets of iron and then getting the iron back is an exploit. There are many other ways to get iron, like the small chance from cobble, or breaking down factory blocks.
