Immersive Engineering

The Immersive Engineering mod will add new electronics and a retro-futuristic feel to the game! Will add many beautiful and functional multiblock structures. Gears use their own Immersive Flux energy, which converts to Redstone Flux at a 1:1 ratio. During the existence of the mod, it has a lot of additions and integrations with other major modifications.
The machines have low voltage (256 RF/t), medium voltage (1024 RF/t) and high voltage (4096 RF/t).

This mod, of course, will not replace IC2, but it will add some zest to industrial builds.
