Hey, Greg. I've just been looking through recipes, noticed two oddities.
1) Barley seeds (from Natura mod) are accepted by Squeezer, but not Juicer.
2) It seems that it is very difficult to make a vanilla Anvil. It requires Iron blocks, but basins outputs "Blocks of solid Iron", which do not work for the crafting. According to NEI, there are only two other ways to make an Iron block:
a) IC2 Compressor (requires electricity), GT Compressor does not have that recipe;
b) Boxinator (which also requires electricity).
And there's also one question that bugged me for a long time - I can't understand at which point Steam Turbine/Engine efficiency is applied.
For example, let's take a standard Steam Engine (Bronze):
Energy IN: 24-96 Steam/t
Energy OUT: 8-32 KU/t
If I understand correctly, if I'm supplying it with exactly half of its input capacity: 60 Steam/t, it should output exactly half of its output capability: 20 KU/t.
Since a Turbine/Engine is not a machine, I doubt that efficiency influences the total amount of energy required to process a recipe. So... What does that efficiency parameter mean?
