I have an idea. [...] a whole new liquid/item. Antimatter.[...]
Yes, that is an idea. I'm not satisfied with the generation method for this antimatter stuff, though -- I don't want to just copy UUM but give the new item just one reason to exist. A thought would be to have this item act as an explosive that never drops items (basically a small nuke with no drops). I'd want a whole industry chain for making it, though, including making containers that can, well, contain it, that would be highly expensive and/or time-consuming to make. And still I'd want more reasons for it to exist.
I'll keep it in mind and perhaps fiddle with the idea more in my copious spare time. Feel free to refine the suggestion further.
I'm having some issues replicating liquids using the refinery.[...]
I wish I could just tell you it was something you were doing wrong, but I have no idea what's causing that. It happened to Zerrens before, too -- his solution was just to update to Minecraft 1.4.7, and I imagine you've already done that, and it still didn't seem to be a complete fix. The problem with fixing it is I have to be able to reproduce it myself, so I can poke around the internals while it's happening, and I haven't seen this happen here. Right now I'm guessing it's something slightly odd about the refinery, but that's about all I can say.
I'm more than half-tempted to add an electric refinery to try and mitigate this issue, but that's going to be a while until it happens. In the mean time, the more you can tell me about how to make it happen on my own computer, the more likely it is I can try to fix it.
narc, I would love to see the Accelerator have 3 different faces for texturing, Top/Sides/Bottom just to allow for a bit of variation in the texturing.
Two problems: firstly, the accelerator can be rotated to face any of the six directions -- define for me "top" and "bottom" when the machine is facing up or down: do I replace the top/bottom texture with the machine-connected face, or do I try to rotate them, say, north and south? Second problem: the accelerator's current texture has always been intended to be purely temporary -- FunnyMan3595 has kindly donated a renderer for the accelerator internal tank's contents, but I need him to help me draw the enclosing tank itself, and then I need a "machine interior" texture, and to decide how I want to render said machine interior.
This is my next priority after making the Liquid Electrolyzer work, and while I have some idea of where I'm going with it, it's going to be fairly fiddly work that will take a little while. Please bear with me until I get there, as I really can't accept textures for the accelerator until then (unless, perhaps, you have a nice "IC2 machine innards" texture I could chop up and push around).
