Missing generator - bug or intended?

  • Hi
    I was browsing through textures within the newest ic2 experminetal build (as of now it is #633) and I found a texture for Kinetic Water Generator. But it is not showing up in my inventory, I also looked through shaped recipes file inside the jar, but there is no recipe for this machine.
    Is it a developer mistake, is it my game, or you just haven't implemented them yet? I really need them actually :)
