Universal fluid cells from IC2 (IC2 is mandatory mod). Shift-right click dryer's fluid input side with cell with water. This should put water inside. If that fails, you will probably get water block near heat-related machines... what is dangerous. Better use other mods
You can directly insert fluids into GT machines from a UFC? Interesting, might want to test that in controlled conditions at some point (though I don't need it anymore).
GT also has its own (cheaper, I think) fluid cells. Not sure what behavior differences they have.
I disagree with the bear here: even though branch mining is the best way to get Graphite, and thus Carbon, I'd rather wait for centrifugating Ashes to get a reliable source of Carbon.
It's really quite easy to do, you just need a pile of bronze and there you go. Hunting for graphite to use as carbon really seems like a waste of time. (Hunting diamonds is another story of course. You want that crusher!)
Though maybe scaring up some steel for a coking oven is a motivation now, if you don't find enough lying around.
Just a casual note that wooden pipes require Rubber Hammer if I'm not mistaken,
They require a soft hammer, anyway. I usually use wood ones. Not a lot of uses but they're practically free.
