Oh, an extra cobblestone question. You're not using your cobble correctly if you have "too much".
Cobblestone:
Stone
Stone Brick
Glass
Glass Panes
Obsidian
Sand (Two ways!)
Sandstone (All 3 kinds)
Saltpeter
Silicon Plates
Copper
Tin
Electrum
Gold (Two ways!)
Silver
Diamonds
Brass
Bronze
Tungsten
Lava
Glass Fibre Cables (Yes.)
Pneumatic Tubes
Cobblestone/Stone/Sandstone/Gravel/Diamond/Gold/Iron Pipes...everything except Emerald, seems like.
Gravel
Flint
Advanced Alloy
Iron
Monitor (ComputerCraft)
Do you have too much of any of these?
Because there's more, that I probably just forgot.
Scrap
UU Matter=almost infinite possibilities
And you could filter it into lava, but that's what we call *Yawn*.
Oh yeah, everything on that list is just Cobblestone+Energy. No additional items required, except for the machines.
Whoa...can you make Advanced Alloy? Tungsten, Tin, and Bronze? Eh, not too sure, but there are like 40 recipes for it.
