1. I was purposely trying to find stuff that wouldn't be seen as OP, since silicon is infinite.
2. Look at the original post for future fusion reactor recipes. Some day, Manganese + Hydrogen = iron.
... Did you realise it would cost TONS OF EU and TONS OF CROMIUM + IRIDIUM + ... you know ... I mean, I would use that if these recipies were using 120 000 000 EU to start, and then GENERATING like 2048EU/t ... (which is really almost nothing, but hey, that's Aston curve) It's not like you can't already get tons of Iron with GT ... I'd agree about automating Tungsten (even though you can already make it with Lava ...), but Iron isn't really that valuable with GT.
Gold (Au, 79) + Hydrogen (H, 1) = Mercury (Hg, 80)
... Again, a stupid one. Why ? Because, the main use of Mercury cells (apart from maling SU-batteries or RE-Batteries, which aren't that used when you reached the Fusion Reactor ^^) is in the Ind. Grinder, and you get it from REDSTONE, i.e the thing you have tons of, plus it also has tons of cool byproducts ... so what I'm trying to tell you, is that Basically, Mercury Cells are used for Platine/Iridium and ... GOLD. Make Gold out of energy, Hydrogen and Gold, HAYO!*
*This HAYO! is really the one you shouldn't trust. Because that's related to our worst product ever.
So, no Welded Blast-proof blocks then?
Once again, and Greg will tell you "so, you won't stop telling me about Molten Salts Reactors Welded Blast-proofs blocks ?". A few more and you'll be added on the Denied Suggestioners List, so Sirus won't feel alone
