INFINITE Furnace Fuel using Crafters in Minecraft 1.21

In this Mumbo Jumbo Minecraft redstone video, we take a look at creating an infinite furnace fuel super smelter using an automatic kelp block crafter. This industrial super smelter takes kelp from a fully automatic kelp farm, automatically smelts the kelp using a furnace array, then sends half the kelp blocks to a giant Minecraft super smelter. All in Snapshot 23w42a for Minecraft 1.21.

I completely forgot that kelp is counted as a 'smokeable' item. Swap out the furnaces for smokers and it doubles the speed if the system. Not that it matters massively, as the bottle kneck is the size of the farm and not the system, but still. FAQ: 1. Could you replace the item splitter with just letting the furnaces fill up? No, because of item elevators - the items would get stuck in the elevator! 2. 80 items per furnace!? Yep - there's a hopper above! 3. Could this be simpler? Maybe, but it's actually really simple, just super compact so it looks more crazy. 4. What if it backs up? Not sure! If I were building this in my own survival world I would have an overflow switch; Or make it so the items divert over the furnace array into a bulk storage system.

Plant on mud, hoppers direct to the center then backwards into a crafter 3 blocks underneath the pistons.

[@SharkyShocker]

I'm glad you're having so much fun Mumbo! There's so much you can do. I'm curious when the "Remote Crafting Table" will be done, presumably from a storage system. There are many ways you could go about it. Presumably you wouldn't need to make it accept an input for every item in the game. You don't use shields or iron pants for crafting. However, things like cobblestone, iron, sand, redstone, and so on you do. Unfortunately, it's difficult to get the items to come out how you want depending on the shape of the item... So really, your best bet is to have an auto-crafter with every pre-set shape that is used for crafting. Then in terms of inputs, you have a series of levers with item frames. Presumably, you can also just have presets for the auto-crafters depending on how many you have. As with any big project, the first step is starting out small though. A 3x3 acts as a 1x1, 2x1, 3x1, and 3x2 all on its own. Then just make a 1x2, 1x3, 2x3, and a 2x2. That's a majority of crafting recipes right there. Armor and tools will be a pain. Though the real challenge likely won't be the size, it'll be getting the items to go to the correct crafter without getting stuck in the wrong pipeline. Or worse, what happens when you put in the wrong recipe. Obviously it's easier to just be given the items, but can you really call yourself a Redstone Expert if you can't craft from 6 chunks away?

[@TrueThanny]

There's another way to do a completely automatic refueling setup. You combine a moss-based bonemeal farm, an azalea-based wood farm (no need to plant saplings), and an auto-furnace setup that turns that wood into charcoal. That charcoal feeds both the charcoal generator itself (after some initial seeding, of course) and, when full, a separate auto-smelter setup. Absolutely massive setup, which you can see in one of Doc's season 9 videos.

Technological advancement is a catalyst not a cause, it spreads and amplifies stuff that is already there. Exploitation of people, resources and nature happen in the name of profit, and have happened in the name of profit way before the Industrial Revolution, just (as I said) on much smaller and thus less impactful scales. Side note on the psychological issues part, just because medicine in the past was incapable of recognizing and diagnosing these issues doesn't mean that these issues didn't exist. Also I really don't see the "unfulfilling" part, the life of the long gone past that was basically a daily struggle to survive until the next day doesn't seem all that fulfilling either.

In a traditional item sorter, advantage is taken of the fact that hoppers pull faster than they push, so items are pushed across until they reach the hopper that will pull it in. I'm surprised you didn't just loop a hopper line or water line around to feed the furnace then push across to bulk storage once the feeding hopper is full.

How about an item filter to just pull out a barrel's worth of kelp blocks that is used to feed the kelp production? Once it's full, it would lock, and any overflow will go into the smelter. It would take a bit longer to warm up and fill the barrel, but feels much more simple and would serve as a nice buffer if it is always on at your base.

An RS latch for a chest. A signal of two is more than enough kelp to fire it.

[@sp3edy787]

Similar premise but different; route the dried kelp block output through a hopper minecraft that circuits over the fuel input hoppers without looping (so when released will run over each hopper once and then return to it's stop). Link deployment to the same trigger as the un-smelted kelp minecart. When using 8 smokers that will keep the farm indefinitely fuelled with the exact correct amount and then have the true farm output via a hopper under the minecarts resting place that is locked when the minecart is less than 2 signal strength full aka 42 items (just increase the signal strength for a larger and more reliable cache). Bare minimum cache with no worry of overflow or drama splitting the correct amount out to be reused as fuel. If your kelp farm is crazy fast use the smelting component as 1 module, hopper minecart magazine and chain the modules with rail switching to divert past the module if its currently operational. Scale to Bonkers, job done.

[@prebenkul]

I just tried to make a simpler version and its literally just a water stream on top of some furnaces with the kelp, then the dried is transported underneath to a crafter which pops them up in a water elevator to a water stream to hoppers on the side of the furnaces, Literally no redstone other than 2 observers for the crafter, just some simple water flow. All u need to do is let the kelp fill up the furnaces before adding the starter fuel.

[@darkejon]

I built this leading into a shulker loader and bulk shulker storage. Then my furnace array calls for two shulkers on demand to fill the fuel input double chest when it empties. I tried doubling your smoker/crafter setup by mirroring it, however the kelp input rail at the top of the array is directional - the flipping rail track attached to the detector rail that determines if the cart is empty flips back the wrong way, so it can only be used in the one orientation. Awesome design Mumbo!

for the redistributing kelp to the furnaces, just use priority output, allow the system output to draw from the rerouted line only if the input buffer is not empty. then as long as your average kelp production slightly exceeds your smelting capability the input & in-furnace fuel buffers will take care of the kelp production variance too. Sure it'll be a little less efficient but will make the footprint smaller & the circuitry simpler

[@jasonso2056]

Kelp-based smelting was the first thing that came to my mind when the crafter was introduced! Although my version just has a kelp farm and crafter directly connected to a super smelter. The kelp from the farm gets smelted into dried kelp which gets filtered out of the furnaces’ output to be crafted into blocks which go directly into the fuel slot. Looking at your version, maybe having a separate smelter for the kelp might be more efficient, but I kind of liked the idea of everything being smeltable in the same furnace system, kelp and all.

[@MiloThatch420]

My answer to the complicated circuitry is just to feed it enough kelp to constantly be full. Thankfully I've figured that out in the past. Suffice it to say that you need roughly 64 kelp/furnace, and that's easy enough to remember. I recommend more in small scale (I use 129 for a singular smoker), but comes out to a fairly clean 63/furnace at large scale (though I always recommend just adding a few to keep up with rng of random ticks).

Seeing how efficient the Kelp farm is. You could just save a lot of room and resources at the expense of it being less efficient and losing Kelp

[@pyromaniac000000]

Heres a simpler way to detect items. Instead of reading the fullness of the furnace, you instead use a comparator behind a block to detect the fullness of the HOPPER. Since the hopper has 5 slots, which will each stack to 64, thats 310 items, divided by 15 for the maximum signal strength when full, gives us 21.333 items per 1 signal strength. This means once the hopper hits 22 items, the comparator will give an output strength of 2. We can detect that, and activate a small clock that deposits exactly 4 kelp blocks into a smoker, and then, the block between the hopper and comparator is moved by a piston, breaking the ability for the comparator to give an output. This activates an ethos hopper clock, which will run for exactly 400 seconds, as thats how long it will take to smelt 80 kelp in a smoker, since thats how much 4 dried kelp blocks will smelt. A quick google search shows hoppers move items at a rate of 2.5 items per second, so that putting exactly 160 items into the hopper clock will give a timer of exactly 400 seconds. After that, the furnace runs out of fuel, the block is moved back between the comparator and hopper, the clock is turned off, and it is reset and ready for another round of checking.

These videos are great and are a big part of why I was excited after seeing the crafter.

[@Mayflower-Yev]

This would actually be a cool block to use with Create mod, whenever they add compatibility. Imagine the conveyor lines to create more complex items, like muskets or guns. Just mass producing ammo, food, blocks, armor, vehicles… Pair this up with automatic farms for like cobble and anything else you might need, and suddenly you have a Military Industrial Complex on your hands.

[@RealisticClover]

idk if you know or not but create already has auto crafting similar, albiet made of multiple blocks not just one, that does this

[@Mayflower-Yev]

@@RealisticClover Well, now it’s easier I guess.

[@spykillergames8402]

@@Mayflower-Yev yea no the create autocrafter was always easier and still is...as you dont need redstone to make it craft

[@Mayflower-Yev]

@@spykillergames8402 That’s cool, I guess I’ll have to stick with water conveyors then, unless I want to do a Create powered auto-crafter. At least in MC it’s a single component, unless I’m missing something.

[@bfrobin446]

​@@spykillergames8402 The Create autocrafter is made of brass, so you can't use it until you've explored enough of the Nether to find blazes and make blaze burners. You can use vanilla redstone without going any farther into the Nether than it takes to gather enough quartz.

I was waiting for this!

[@Xhepyxopila]

Can't wait to watch this! :D

[@evanbookout]

did you watch it

[@trueblueflare]

It took this to make me realize that kelp blocks are actually better fuel than coal/charcoal, which is both cool for me because I usually like to play with the Create mod and as such almost always have an automatic kelp setup, but also not that useful for the same reason because you can just smelt/smoke items using Create machines without needing fuel lol. Either way, good to know for when I'm not playing with the Create mod.

[@1994AustinSmith]

In terms of returns, if 1 kelp block cooks 20 items, divided by the 9 kelp to craft it is 2.222..., minus having to cook them for a net of +1.222... smelts per kelp. With charcoal, -1 to cook the log into charcoal, which cooks 8. That's a net +7. I'm sticking to charcoal, but will have kelp as a fully automated secondary fuel.

[@elizabethburns7810]

I was trying to figure this out! Yes! Thank you mumbo!

[@inzanity7212]

I love that you’re on the case with the crafters. ❤

[@Micboss1000]

For a small farm, you can have a hopper clock with the fuel burn time that's locked by an inverted comparator signal from the furnace. As long as there's enough kelp coming in, the hopper clock will keep sending fuel on the preset interval.

[@petemoss7704]

[@Axolotl165-jo6mp]

I love how he was like "in a 4 furnace setup, each furnace will have 80 kelp". I didn't know mojang changed the stack sizes!

the hopper.......

It would fill up the hopper above it :)

[@stillinhere]

Best idea for the crafter I’ve seen. Some are complaining about the crafter, already, but I think it can be great if used well. This will be something I do, too, when it comes to the game.

[@mylittleparody2277]

Sweet! I didn't thought it would be so complex. Thank you for your ideas! Hope this one will go in the Hermicraft server too

[@GeneralNickles]

I feel like there has to be a MUCH simpler way to do this. Like a single hopper minecart that travels along a looping track that takes it over both the fuel input and under the crafter output. It would take the kelp blocks from the output and loop around and drop them in the fuel input. (Probably just one block at a time, so it'd be slow unless you do some detector rail stuff that I don't understand.) And the raw kelp would just flow into the furnace directly from the farm.

[@ThatMumboJumbo]

That would only ever fill up the first few furnaces. You have to do it in batches. This design basically does what you said, but in batches, in the smallest possible footprint which is why it looks a bit complicated.

[@JoannaFalkowska]

@@ThatMumboJumbo Just fill each with a stack of kelp blocks at the beginning? Then if the production is higher than the consumption, with one output line going through them all, surely they would all stay fuelled forever, wouldn't they?

[@smittzero8463]

That's pretty complex. I think I would rather stick with a bamboo farm but use the crafters to convert the bamboo into planks for increased efficiency.

[@SalamanderBSC]

A simpler way to improve efficiency is to feed those planks directly into the furnaces that smelt kelp. To make a kelp block you need to smelt 9 kelp, which requires anywhere from 6-9 planks if you don't bother with any timing and just shove planks and kelp into whichever furnace is available. So you trade in 9-13.5 item-smelts of fuel for 20 item-smelts of fuel, i.e. you get an extra 7.5-11 item-smelts of fuel, with the added bonus of it lasting longer so the possibility of furnace arrays running out of fuel because the delivery system is too slow is substantially reduced.

[@thomasbennett8537]

I already have a dried kelp farm. They're incredibly huge and slow. Before my wither skeleton farm completely blew it away. Coal is just a better fuel.

[@brimp4989]

Yeah but its kind of a bigger time investment because then you gotta make wither skele farm in the first place, the coal sorter, automatic shulker swapper which shulkers require the farm of their own, go to the nether and bring the coal shulkers back, make the super smelter when you could make that kelp farm and the super smelter at the same time not to mention you have to have the wither skele farm loaded in with either your own player or a chunk loader while the super smelter is just by your storage area so it should be loaded the most.

[@Ditchedd]

I had a dried kelp farm on bedrock and i would just hop on the realm sometimes and go afk to get it to work while i eat or something, it was a fairly small farm so it was pretty inefficient. If i wouldve made it bigger it wouldve been more worth it

[@Loki-vl9vp]

Cool idea as usual, I know that it's not likely you'll read this, but after watching the video it gave me a few ideas on how to optimize the design, The issue with splitting the output is obviously quite a bump in the road, personally the way I would've handled it would've simply been to have the output fuel to kelp furnaces first, and then route any overflow to the actual supersmelter, this "bandaid solution." could also let you ignore the whole furnace efficiency issue (if your kelp farm is fast enough to keep your furnaces satiated). Also I believe you can use smokers in this instance as dried kelp is a food source.

[@carlostras5554]

Very good video and farm, but you could have used a hopper to give all the kelp to the farm, and when its full the rest will be deposited in the smelter

[@ThatMumboJumbo]

Wouldn't work, read the FAQ! :)

[@Werewolf914]

This might be broken or too OP but I wish instead of locking certain slots and having to funnel in items in a specific order with loads of Hoppers that you could just open your recipe book and select the recipe you want and that would lock in that recipe and you could use just one Hopper and chest(s) and the items would just automatically sort into the correct slots.
