Understood. Quite clearly, since one GT wire seems to equate to two IC2 wires, we want to use IC2 wire/cable whenever possible in a crafting recipe since the wiremill gives us double the amount. The only time I'm using GT wire/cable is when we do not have the option to interchange them. I don't quite understand how/why they are sometimes interchangeable in recipes, and sometimes they aren't, but whatever. I don't make the rules, I just try to figure them out and follow along.
I got very very very lucky in my world. Somehow (random chests?) I acquired 12 nether quartz, which was just barely enough to make my first 8 EnderIO pressurized conduits so I could get steam from my boiler/buffer tank to my steam turbine. Why is that lucky? Because I cannot figure out any way to get a solitary steel nugget... which I need to make flint & steel, which I need to light my first nether portal so I can go and get more nether quartz. If I had less than 12 quartz, I might be stuck without any conduits and still trying to figure out how to make it all work. But yeah, the EnderIO pressurized conduits are everything the TE3 conduits used to be.
Also... railcraft boiler really use a lot of coal/charcoal. Holey moley. I'm not sure I like that very much. And it also uses up water too fast. I'm lost without a TE Aqueous Accumulator and haven't figured out a way to get water into the boiler except by hand. I already let the boiler run dry once already, and had to shut it down and lose all that heat. What a waste. I guess I can use an IC2 pump? Why doesn't Greg have any pumps amongst his machines? Or does he?
