Best way to generate MASSIVE ammounts of EU?

[Bigpak]

if youre willing to put GT in, you don't have to fiddle with IDs, and its relatively easy to go into the configs and neuter most of the insanity. (I like ultimate GT. do not like unhinged raw GT. change a few configs and you get the good ole' fun GT back)
point is, fusion reactor. large resource cost, large infrastructure needed to fuel it, but it produces insane amounts of EU. forever.


on the subject of boilers, how larger of an unfertilized MFR treefarm (what size upgrade) do I need to run a 36HP boiler?
I have a tin upgrade (r=4) currently in use, have a large wood stockpile from fertilizer.

I'm waiting on putting GT in until I get bored of the current stuff, as from what I have seen gregtech adds a lot of amazing things.

do note that GT requires world generation, so you might need to make a mining age to get the ores from GT

Yep, already got all that sorted I'm just worried about setting up the config after looking at it... dear god so many options its amazing. I like gregtechs config as I believe it allows you to fine tune everything.

That's odd, how are you getting a conversion of 100kMJ/t to 143k EU/t? Shouldn't the ratio be 2:5 with PowerConverters?

It should actually be a 1 : 3.125 ratio. A 36 HP boiler produces either 144 MJ/tick with industrial steam engines, or 450 EU/tick with Steam Turbines.

MJ/EU

4375/1800 ~2.43/1

Or in other words; 1 MJ to every 2.43 EU.

For steam every 5 milibuckets is worth 1 MJ or every ~2 milibuckets is worth 1 EU

Hoff,

Those are Power Crystal's PowerConvertors configs from config/powercystals/powerconverters/common.cfg and thus his (her ?) default ratios, not CJ's RC Steam Turbine's ratios. While there is rough consensus on the 2:5 MJ/EU ratio, it's not written in stone and every modder is free to do their own conversion factor.

 

[Hoff]

At least read what he was quoting -_-

But if you insist Turbine ratios for Railcraft are 1.6 milibuckets to 1 EU. The values are also the exact same for GregTech carbon rotors as well, in case anyone else was wondering.

 

[MigukNamja]

...and I could not find a similar such config for BuildCraft. So, we'll have to go with in-game verification of the Steam Turbine.

I don't even know what you're talking about at this point...

 

[MigukNamja]

I was. Were you ? He was quoting RC Steam Turbine. You were quoting/using/referencing Power Crystals Power Converters.

But if you insist Turbine ratios for Railcraft are 1.6 milibuckets to 1 EU. The values are also the exact same for GregTech carbon rotors as well, in case anyone else was wondering.

Hmmm, yes. 1.6mB:1EU ratio and a 5mB:1MJ ratio make for 5EU:1.6MJ ratio, which is 3.125EU:1MJ.

3.125:1 > 2.5:1 (5:2)

Hence, Steam Turbine is an even more efficient use of steam than Steam Engine, rotor durability ignored.

It should actually be a 1 : 3.125 ratio. A 36 HP boiler produces either 144 MJ/tick with industrial steam engines, or 450 EU/tick with Steam Turbines.

Exactly, yes. 5/1.6 = 3.125 and 450/144 = 3.125.

I don't even know what you're talking about at this point...

Typo. I mean Railcraft.

 

[Hoff]

I did actually ignore the person I quoted past the first sentence. Oh well. Turbines weren't a reference from the original quote so I didn't give it much thought.

 

[MigukNamja]

Yeah, I hadn't realized how efficient RC Steam Turbines were until this thread ! I always learn something new here

What are you talking about? We're talking about Power Converters, not Steam Turbines. It's nice that Railcraft provides a more efficient conversion of steam to EU than the conversion of steam to MJ to EU would allow, but Power Converters follows the simple ratio of MJ/EU that you get if you just compare the energy values of common fuels like coal or lava.

 

[MigukNamja]

AFAIK, there are no 'common' MJ / EU energy values, just vanilla furnace burn values, and those aren't in play here.

To be precise, an RC Steam Turbine doesn't 'convert' MJ to EU directly. It converts steam to EU. But, many people - including myself - use RC Boilers to drive RC Industrial Engines and 144MJ/t for a 36HP is taken as a benchmark. So, if you can get 450 EU/t vs. 144MJ/t, that's roughly a 3.125:1 conversion ratio since you're getting EU rather than MJ. Hence, you're "giving up" MJ to make EU instead.

And, if we're talking common fuels values like coal or lava, then RC as a whole blows those out of the water. Consider the 'free' upgrade (time ignored) from coal to coal coke. It *doubles* the heat value for Railcraft vs. coal (quadruples it for other uses) - and you get creosote to boot ! You then convert that coal coke into steam via RC Steam Boiler, and boilers vary in efficiency. After that, you can convert to MJ or EU using a few different methods, each with their own efficiency factors.

As for the OP's question about how to generate tons of EU *and* they have tons of fuel, it's hard to beat RC boiler + RC steam turbine. It's more efficient than Power Converters.

 

[Hoff]

It's also more efficient at creating MJ by creating EU first then using it in power converters or electric engines. Increasing the MJ efficiency to almost 140% I believe.

man you know what would make the steam turbine better
-Different kinds of turbines
-Enchantable turbines
sounds kinda stupid at first but if you think about it

The first of those is already done by GT, if that's an option.

Question, how do I get enough ethanol to fuel a boiler? I mean I can get thousands of saplings but the energy cost it takes to run like 9 stills is still pretty steep isn't it? My thing keeps flashing from 512eu/t 0 eu/t from the power converter.

wouldn't it just be easier and much more efficient to use fuel? Why do people use ethanol? fuel is renewable?

also coal coke, how do people run boilers off of it, how do they get so much? I'm not interested in anything other than 36HP or 36LP, how many coke ovens do they have?

If it's flashing when it has a constant supply of EU and the charge bar at the bottom is full then they're getting more power than they need. Boilers only sip biofuel and fuel once they're fully heated. Get a supply of 500-700 buckets and you can fully heat a HP36 and it then only sips 35 buckets an hour(Biofuel, fuel is less). Fuel is also renewable through two methods but it relies on already having some form of liquid to heat the boiler first. The oil fabricator requires less MJ per bucket of oil(+ refining) than is produced by one bucket of fuel in a fully heated boiler. It's not a huge gain in MJ but it is a gain. You can also use bees to do this.

The reason most people use biofuel because it's fairly simple to setup and once you do, you never worry about it again.

I couldn't say for sure on the calculations but it'd probably be in the 20-30s range per boiler(Not including creosote). The coal can be gotten from a wither skele farm. You could also go the route of sugar/cactus. Cactus requires double the ovens of sugar since you can smelt the sugar in a furnace but cactus produces more creosote because of the added ovens. I'd say at least 80 ovens for sugar and 120 or so for cactus.

 

[Bigpak]

So basically use biofuel or fuel, I mean I have a ton of oil backed up in tanks that I can refine and throw in some boilers for extra power. How much EU/t does it take to get one of those laser drills going? (4 prechargers)
