Current: To the best of my knowledge, all generators can be broken and return a vanilla generator.
- Vanilla (of course)
- Haven't tried Nuclear, nor windmills
However, due to the possibility of getting infinite iron via creation/destruction, watermills always return themselves.
Suggestion: The addition of a shapeless recipe that would take 2 watermills and return a vanilla generator. The wood used originally would be lost.
Why?: Let us suppose to either don't use watermills after a certain point or you decide to change that watertower into something else. Without this, you are forced to either recycle the tower and hope for the best, or leave it and go find all new redstone, tin, and iron. With this, you will still need to get the upgrade materials yourself, but at least you have the base generator.
Another way of saying:
- current Cost of 1 geothermal = 2 refined iron + 4 glass + 2 cells + 1 generator
- Cost with suggestion implemented = 2 refined iron + 4 glass + 2 cells + 2 watermills.
