Twice the listed EU/t for any given recipe. For the high pressure machines its 6 times as high.
What's the highest "EU/t" operation each steam tier can perform? 8? 32?

That link hasn't been accurate for a long time, it even says so in the link. Right now the best an LP can do is a hair under 36buckets per charcoal (the absolute best is a high pressure coal boiler at 48, but chaining together a large number of small boilers is a huge headache).
But the point isn't for constant power, at three times the steam/bucket LP boilers are the clear winner for that. the point would be for emergency power when the heatup time for more 36LPs is shit. Run the treefarm and feed all the charcoal into the LPs, stockpile the biofuel for on demand power.
But now that I think about it, it's probably a lot better to do it the other way around. Biofuel for the LPs, grab JABBA and make a massive charcoal stockpile with the spare for the large boiler, gives the best efficiency overall, and two minute warmup is nothing compared to most steam setups.
I got my 36 number from the simulator but that isn't right.
If what you're saying is correct then no RC boiler can be 3x more efficient than a tungstensteel boiler. In fact ignoring heatup the GT boiler wins and accounting for it the GT boiler really wins.
If you think there will be enough ethanol to keep large RC boilers going then there's going to be a lot more charcoal. The ratio of charcoal to ethanol is ungodly. 5 trees worth of wood (something like a stack of charcoal worth 1600 heat each) for 1 bucket of ethanol.
Ethanol is nice on paper but it's not balanced to be used for anything other than straight up emergencies. You set aside a tank and keep filling it and when you blow up other stuff then you flip a switch to use it while you fix stuff.

1/3rd the efficiency in a tungstensteel boiler as the 36LP, but since heatup is nearly instant, it's a good backup power source.
I'm sure I don't need to mention this post (http://forum.feed-the-beast.co…-boiler-efficiency.13506/) to say that max RC boiler efficiency should never be considered steady state. Since that post there has been rebalancing but from looking at things it looks like a max 36 LP boiler at max temp (500C) outputs 360 mB/t and consumes 1 piece of charcoal every 10 seconds. I'm not going to go into the details of heatup but just keep a number of something like 20% efficiency loss in the back of your head.
RC LP36:
360 mB/t * 20 t/s * 10 s = 72 buckets of steam per piece of charcoalGT Tungstensteel:
2000 mB/t * 20 t = 40 buckets of steam per piece of charcoalNow when you take into account the heat up and cool down costs they're not too far apart in terms of performance but (!) you won't need a ton of boilers to make a lot of steam and the heat up time is on the order of a few stacks as opposed to a few dozen stacks. The simulator's busted right now so I can't give you actual heatup numbers for the RC boilers and I really cbf'd to do that math rn.

You don't want to even look at the numbers for how many saplings/sec it takes to keep a large boiler fed.
In case you do:
Now the actual rate of sapling drops per tree is dependent on the tree. It's 5% per decayed leaf block. I'm gonna skip trying to do a rigorous proof and just guess from experience that a tree will drop 2 saplings on average. Use 1 to replant and 1 for ethanol. From here I'm going to assume you're using forestry and assume that the tree is oak (the apples can be squeezed for supplementary biomass, another estimate of about 20% increase in yield as well as supply the compost).
300 mB of biomass / tree
100 mB of ethanol / tree (GT distillery is 3:1)
5 trees / second to keep a boiler suppliedNote some guess work and uncertainty is in there. You can't rely on RNG so make buffers and overproduce. This is impossible to do without mods that add tree farm automation and even then short of MFR you'll need to have a pretty large scale set up.
An alternate solution that can net you quite a lot of efficiency (guessing between 10-40%) is to have a large tank that the boiler will fill until it's full then the boiler will turn off until the tank is empty. This way if you're not pulling enough energy to keep the boiler turned on you won't be wasting fuel but if you're running lots of machines the boiler will stay on for a long stretch, being very efficient.

Someone made an excellent post about 20 pages back on the main GT thread about small boiler math. It was pretty detailed. I'll see if I can dig it up.

Nice lack of tab support on this forum. Is it two thousand fucking two already?

On the electrolyzer for underwater breathing: you should have one cell of oxygen last something like two minutes and make the electrolyzer have tanks of both oxygen and hydrogen that need to be offloaded when full. Better yet make a tank module for the oxygen (possible explosion hazard?) for underwater breathing with an optional electrolyzer for sustained underwater breathing.

Something like this:

But, ya know, as an entire factory.
By the way, the connected stone blocks are from Extra Utilities, and the lamps are from project red. The stone can be replaced by certain kinda of chisel blocks, be creative! The lamps can't really be replaced, though...

Also as of right now there's no real mod that actually handles frames the way redpower did. This is a pretty big thing but I feel like the scale of the projects that frames are used for is up gregtech alley. Adding systems to keep the frameships airborne or integration of pipes/wiring/redstone into the frames so you can route items, steam, EU, and control around the frame.

I suggest replacing iridium with helium cells in the superconductor recipes. Iridium is a strong material but it's not really necessary for a superconductor.
Also adding advanced fabrication mechanics for circuits would be neat like requiring a boule spinning machine for advanced circuits and a foundry multiblock for anything higher. Maybe it's configurable to not be necessary but at the very least it will be a more efficient use of resources.

Guys, what if the fusion reactor built upwards is actually a stargate but Greg has never told us? Sinnaj would lose his shit.
But seriously, I assume it is kinda tedious to implement it, but for something as big as the fusion reactor, it could be worth the effort (do these things actually work now?)
I remember making one towards the end of mindcrack 8.2.0 (I think this was minecraft 1.4.7/Gtech 2.x) and it was a bit confusing.
I have one (soon to be two) running great on my unhinged survival server. The plasma system is actually a lot better than EU. Also with MFR things like lithium are easy to automate production of, and centrifuging lava gets tungsten so I actually have iridium fusion on the same reactor as helium fusion. Applied energistics automates with a little computercraft/openperipherals control to make sure I always have enough plasma. I'd say it all works surprisingly well.

Hey Greg, love the mod.
I've started building vertically for space efficiency. When coupled with factorization's router, applied energistics, and "barrel" style layouts (1 EU cable in the center surrounded by 4 of the same machine on each layer) you can make some very compact designs.
My suggestion is including a transposed mode for your multiblock structures. What I mean by that is making the component layout not necessarily in the x-z plane. In particular the fusion reactor. The other machines like the blast furnace could have some strange looking designs come out of it for advanced machine casing efficiency (number of advanced casings per machine block). This would ultimately be a more aesthetic change but could have some interesting consequence. I'm also not familiar with the ins and outs of minecraft and modding so I don't know how practical building multiblocks in the x-y or y-z plane even is from a coding perspective.
