What does YOUR Power Room look like?

[Evil Hamster]

you can get iron by crafting iron furnaces (5 iron and 1 furnace) and macerate them again (8 refined iron > 8 iron dust > 8 iron ingots). Though its some cheaty exploid tbh

There are other exploits that generate more iron in a cheaty way, but other than trying it once to see, I won't ever use it. Hope it gets fixed soon!

Well, as far as I am concerned, Iron is not a shortage, as I nearly I have it in quantities nearly equal to all the other ores added together, but that might be luck.

I'm definitely not short on iron, it's more that I use more of it in proportion to the other resources I get. So far I only have 4 iron tanks with I think enough to build one more, but that will leave me dangerously short. I want my auto-processing & sorting system a bit more functional before I restart my quarry.

 

[slay_mithos]

Oh, yeah, for Railcraft tanks and power houses, you need tons upon tons of Iron and steel, I tend to forget about that...

When I though I had what I needed, I saw that I needed to double my iron in order to be able to build it.

Well, that means that I won't be having massive power just yet.

 

[Stanekk]

Yeah but if you concentrate on getting iron a lot, it doesnt take too long!

even more oO
this is already more than 50% gain
and you can loop it so it can autocraft itself in a insane speed
maybe I should check NEI agein :3

If you looked at the post above mine you'd understand what he was doing with it. With current conversion ratios, you can melt cobble in a magma crucible to produce a bucket of lava for 20k MJ. That bucket of lava can then be fed into Geothermal Generators for 20k EU, so it's a 1:1 conversion of MJ to EU, which is much higher than any other conversion ratio outside of Turbines, which require a fairly large amount of steel for their upkeep. With this system there is 0 upkeep outside of fuel costs.

I know this thread is a little old, but I still have a question regarding this. I had the same setup going - 6 magmatic engines powering a magma crucible and the lava would feed both the engines as well as a geothermal generator. I would always use netherrack in the magma crucible, not cobblestone. I'm not sure of the exact numbers, but consider this:

Magma Crucible:
cobblestone: 20,000 MJ per 1000mb (yes, 1 bucket haha)
netherrack: 8,000 MJ per 1000mb

Now, you'd be feeding that lava back into the engines in order to power the magma crucible:

Magmatic Engine:
Efficiency rating = 90%
18,000 MJ per 1000mb

18,000 MJ - 20,000 MJ (to melt cobble into 1000mb) = -2000 mb per cycle
18,000 MJ - 8,000 MJ (to melt netherrack into 1000mb) = +10,000 mb per cycle

So using cobblestone, you are actually operating at a loss of 2 buckets a cycle, but using netherrack, you gain 10 buckets a cycle that you can put into an IC tank to make sure both your magmatic engines as well as your Geothermal Generator is always supplied, allowing you to run whatever you want. Am I wrong in those numbers? Yes, you do get a 1:1 ratio of MJ to EU using cobblestone, but it's inefficient fuel-wise, and eventually you will run out of lava.

The trick is to not power your MJ with lava.

I'm sorry, I don't understand that statement at all. You don't power MJ, MJ is a measurement of power.

You mean not power your magmatic engines with lava? That's how they run. You can't power them with anything else.

He's referring to the fact that MJ systems have a tendency toward lava or EU-based lava conversion, admittedly, I am guilty of this, because it's so quick to set up.

Doing so completely undermines all the cool farming stuff BC adds.

Lava-based MJ generation has been done since the beginning of (FTB) time.

But that's completely irrelevant to my question. I asked why anyone would use cobblestone over netherrack in a lava MJ set up. I'm not disagreeing about farming stuff being a great addition, I'm just wondering why people who are still using lava would use cobble over netherrack when it looks like you operate at a loss doing it that way.

Because an infinite amount of cobblestone comes out of a single block.

You don't have a stockpile of netherrack without using your time to mine some or setting up an automation for it, again using your time to do it. Cobblestone is fast to set up for unlimited automatic supply and you don't have to go into the Nether for it so it is viable for very early game. Ease of automation is the key.

I use cobblestone because it's Infinite.

I use 2 Hybrid Solar Panels (tons of Iridium -- started Beta A with IC2 setup) and siphon some of that power to 4 upgraded (1 Bronze/Iron Tube) Electrical Engines that produce 30 MJ/t using 80 EU/t. This 30MJ funnels to 2 Magma Crucibles turning Cobblestone into Lava. The Lava goes into a 5,000 bucket 7x7x6 Railcraft Tank. This way, I'm producing lava even when I'm not logged in (Chunk Loader). Nearly infinite lava, since there's no way you use 5,000 buckets worth in 1 play session.

I do have a nettherrack override, but I learned long ago that was overkill.

I'm storing 90 Million MJ in that tank at any given time.


The problem is it's boring. I'll probably switch it out for something more fun.

I've currently got about half a dozen combustion engines, which don't seem to be making much of a dent in all the fuel I've refined. I've just noticed that I need to add a second aqueous accumulator now as they all ran out of water and started overheating. (I recently upgraded from having just 3).
I also need to reorganise all my MJ-using machines as the way I expanded the room I originally put them in lead to a fairly haphazard mess.
I don't have any non-MJ stuff built yet. Maybe next week.
I put a full redstone energy cell, two iron chests, and my barely-used quarry in the nether, and discovered that the quarry serves as a chunk loaded. I returned to the nether after only a few minutes and found the energy cell empty and the chests nearly full, so I have plenty of netherrack to melt into lava (using MJ from fuel refined from oil), which I put straight in an igneous extruder which outputs to an autocrafting table with a minium stone. Fairly soon I'll finish constructing the autocrafting chain which will essentially be turning netherrack and oil into iron, gold, and diamonds.

I also want to move the whole thing off this dinky little island...

 

[LittleMike]

DoctorOr - using an igneous extruder (spelling?), yes, but if it takes 20,000 MJ to melt it and you only produce 18,000 MJ with it, eventually your magmatic engine will run out of power and your magma crucible will stop burning it.

Zelfana - also true. I'm just not seeing how it's viable as an energy source with magmatic engines.

jnads - THAT makes a lot more sense. Because you're supplementing it with a different (free) energy source. You'd be gaining 18,000 MJ a cycle because the source is completely free. That's a great idea. Total energy profit. I'm still wondering how people are able to do magmatic engine + magma crucible, as mentioned earlier in this thread, though.

The cobblestone powered magma crucible is purely meant for MJ to EU conversion, you're thinking wrong about the whole thing.

Well if you're not running it 24/7, then that makes more sense. I thought it was being used as a primary power source. It wouldn't work for that. I also find farming a few stacks of nether to take very little time and effort, but everyone's opinion on that may differ. I pretty much run everything I have on 6 magmatic engines/crucible/thermal generator, but it does blow through netherrack. That wouldn't even be possible on cobble.

Netherrack / Magma Crucible is nerfed somewhat in newer versions of TE, check for King Lemming's posts or changelog on the TE wiki for details... might want to consider it before the mod pack updates and your power room has a sad.

Good to know. Thank you! Do you happen to know what thread King Lemming posted in detailing this? I did check the changelog for TE and it made note of the change as of version 2.1.7:

-Changed: Magma Crucible has been rebalanced a bit.
-Changed: Magmatic Engines now require Invar Ingots and Gears instead of Tin.
-Changed: Netherrack to Lava conversion is more expensive - this new default value IS enforced upon updating. You may still change it in the config file.

Now point 2 isn't really that big of a deal, but point 1 and 3 are. The problem is that it doesn't give the actual values. I will have to look into a viable alternative.

I'm not sure - i don't have it saved. Check his post history here or on the /r/feedthebeast subreddit?

 

[LittleMike]

Will do. Thanks again!
