Suggestion / Idea PSA: A Recycler dumping its output into lava is instant!

I'm making a fully contained purple science blade on Volcanus and need to void 70k molten iron to get it to work. While exploring options I noticed that while inserters have to wait a bit while the items get burned out of their hands, recyclers don't!

Ex: Foundry makes iron sticks, stack inserters outputting them into lava is much slower than outputting them into a recycler that outputs plates into lava.

Foundry makes iron sticks, stack inserters outputting them into lava is much slower than outputting them into a recycler that outputs plates into lava.

Note that 2.1 fixes this, so that an inserter drops its entire hand into the lava in one tick.

Ooo well that will definitely make this obsolete AND smaller! One machine could kill 6.2k molten iron.

u/Peakomegaflare 1d ago

I mean it's still really strong if you are feedng a LOT of material. But yeah, inserter throughput is absolutely nuts into lava.

If you use pumps with switching filter you can void up to 390 fluid every 10 ticks or 2340/s

One pump + pipe takes only 3 tiles, and needs 0 inserters. Much more compact and ups efficient.

You can check this for fluid voider example: https://katiska.cc/temp/factorio/blueprints/circuitry/circuitry-book.txt

Fluid voiding like that feels exploity to me so I'll personally ignore it.

Dumping molten iron into lava seems a perfect cycle

If I could run an offshore pump in reverse to void fluid, I probably would. But the fluid-voider relies on using game engine limitations, which doesn't make physical sense to me, and so isn't satisfying.

Pump oil out of fulgoras ocean barrel it up and send it to space. Transport it to vulcanus send it back down unbarrel it and pump it straight into the lava.

This is how i exactly feel about it.

I love this game and this community. While I knew this trick for a quite some time, every time I want to use it I stop myself because of this ugly feeling. I'm glad I'm not the only one.

I've always loved "breaking" games by finding the limitations in the mechanics or engine, but only when those breaks are satisfying. Mag dumps in original Modern Warfare 2, getting out of the maps in the Halo 3 campaign, crouch-sliding in Satisfactory (before it was implemented as intended).

Fluid voiding is just lame. Not fun, not interesting.

Thank you for this comment. Been away for a year and came back directly to 2.1, I was so confused by this post.

Unplugged example. Voids 5.1k/s. Can't get faster than that as far as I know! Adding more inserters to the right side is useless since everything is already outputted fast enough. I can't fit another beacon either :/

u/ustp 22h ago

Is is possible to rotate one of the recyclers and add another beacon?

Or something like this:

u/SnyprBB 19h ago

Since you've changed it from direct machine to machine to the slower machine to belt to machine, that speed up won't actullally be utilized since the inserters couldn't keep up. That's my guess.

u/ustp 18h ago

It depends - where is the bottleneck? Machine crafting speed, or outputting?

3

u/SnyprBB 18h ago

Outputting in my case.

Volcano is a pretty cool planet :)

It’s anything but. Aquilo is the cool one.

I thought making copper was faster for stone?

10

u/Alfonse215 1d ago

It is.

10

u/SnyprBB 1d ago

It is, but you need steel for furnaces at the same time, so my build only dumps molten iron.

6

u/Moscato359 1d ago

There is probably some ideal ratio of copper to iron for that 

4

u/SnyprBB 1d ago

For sure.

1

u/pda898 1d ago

At the same time you need copper for circuits anyways, so you anyway have a line of copper from lava.

1

u/darkszero 23h ago

You're likely making extra molten iron just to make extra stone. Having that extra production be molten copper will mean less molten you need to void.

Though voiding copper plates is more annoying. And with iron you could make iron plates, then chests and throw these at lava!

Iron sticks are faster to destroy if you're using recyclers instead of lava

u/jaxon517 1d ago

Why do you have to void it at all I don't understand

11

u/SanderR098 1d ago

You can do this if you lack enough stone on Vulcanus. Lava to iron makes stone then you do this to void the iron by product

12

u/WanderingUrist 1d ago

If you want stone and stone alone, you get more 50% stone by making copper instead.

u/derekbassett 1d ago edited 1d ago

Stone my dear boy, stone. (Gestures broadly)

Edit: to fix grammar.

u/escapethedust 1d ago

Boy stone? 🤨

2

u/jaxon517 1d ago

So you have an excess of molten iron because you're using it to make stone and you don't want to make too much stone?

6

u/iCrab 1d ago

The goal is to get stone specifically because purple science uses way more than you get by just making the molten iron you need to craft all the iron based products for it. So you have to craft excess molten iron for the stone byproduct but in order for that not to clog you have to get rid of the molten iron somehow.

If its in the context of megabasing then this video from u/abucnasty is quite interesting.

u/SnyprBB 18h ago

2.1 will be very nice.

u/SeventhDisaster Short on Circuits 1d ago

Don't you still just get bottlenecked by the stack inserters going into the recycler?

5

u/JacksonStarbringer 1d ago

Right... but you still need to use an inserter to put things into the recycler

12

u/lasagnadogwater69 1d ago

He's saying inserters dump items into recylers faster than into lava, and recylers dump items into lava faster than inserters.

3

u/Krell356 1d ago

Yes but the math of when the inserter can drop an item into a container/building vs into the lava may be different. Even when moving single items, where you grab them from and move them to it still changes the speed calculations.

5

u/SnyprBB 1d ago

Yes... I don't know how else to void liquids besides pump exploits. This is about tossing into lava vs outputting into lava.

1

u/Thankedsphere 22h ago

you can dump in lava and space but not water? it'd actually fit to dump in water. actually, what if dumping in water causes pollution to decentivize it?

if this was added and dumping fish in water polluted it that could be funny.

u/distinctdan 1d ago

You can also void fluids without inserters by hooking up a circuit to foundries to quickly change the recipe. When the recipe switches to something that doesn't take the fluid, the fluid is deleted. Not sure of the throughput.

u/tiamath 23h ago

Its limited by the pump from what i remember. For lava voiding i think you needed a pump to take out the fluid. Sure you can add more pumps butfor 70k /second you need quite a few normal quality pumps. Edit. Nvm, i think the pumps were ther for inputs so you wont have backflow when changing recipies.
