Hey Guys,

so i was wondering whats the most efficient ways to turn MJ into EU.
i have thought about magmacrucible->lava->geothermal but are there other options? what about that new gregtech-things?

thx

In terms of the gregtech machines: Many of them can now be upgraded with the Pneumatic Generator upgrade, meaning they can be powered directly with MJ. However, there is a penalty for this conversion as you'll only get 1 EU per 1 MJ (instead of 2.5), so this is inefficient.

Obviously power converters....but this might not be what your after (and a little cheaty imo).

I've read quite a large amout of topics regarding this question, so it might be a prime time to have a sticky on this forum regarding this, and a first post to a player's most efficient solution.

Well, the oil fabricator requires 600k MJ to produce 1 bucket of oil. One oil cell/bucket will output 64k EU (approx 25.6k MJ) from a semi-fluid generator. Refining the oil into fuel will give 384k EU (approx 153.6k MJ) per diesel/fuel cell in a GT diesel generator. So still not worth it.

(The only benefit of the oil fabricator, that i can see, is to refine the oil and then pump the fuel into a boiler to get a profit of about 270k MJ/bucket)

The simplest way without power converters or transferring to another medium is a bank of electrical engines with iron upgrades. Bog standard 2.5:1 conversion ratio, but eh, it works. oil is a bad conversion unless you are using steam as a medium (boilers)

I dont want to convert EU into MJ - i want to convert MJ into EU...

and i dont have power converters

I think i remember the steam boiler -> steam turbine from railcraft being pretty darned efficient once set up for EU production, not really converting from MJ but its close.

Easiest? I think its one of the generators can't remember which. Most eeficient? still MJ source to magna crucible with netherrack to lava to geothermal generator.

After the turbine buff in 1.5.2 and onwards, this is in fact the single most efficient converter in the game, beating out Power Converters, magma crucibles, everything. However, you have to pay for that efficiency with a huge up-front investment in both resources and fuel (unless you already have a heated-up boiler). The best is also the most expensive.

Yeah that's the route I would take, assuming using boilers is an option.

If you have GregTech installed, then Greg's turbines, with carbon turbine rotors, are the most efficient way of getting eu from steam there is. Only problem is that carbon turbine rotors don't last very long, and you have the expense of the turbine itself. But if efficiency is what you're after, then the Greg turbine is the way to go.

Power converters are still better IIRC. They should make 422 EU/t from the steam while two turbines produce 400 EU/t, correct?

With power converters, you get 350 eu/t from one 36hp boiler. I don't know what the conversion rate for a RC turbine is, but with a GT turbine its 1 eu per 2 steam, meaning you can get 360 eu/t at 100% efficiency. However, carbon rotors operate at 125% efficiency, giving you 450 eu/t. Though to be honest, power converters are so convenient, I prefer to just use them.

Oh wow yea. I dumbed my math a bit. Turbines are the most efficient.
