For anyone else wondering:
Bucket Wheel MKIII
Mining Speed 45
Energy Usage 16560kw (368kw per Mining Speed)
Pollution 712.08/s (15.824/s per Mining Speed)
Mining Radius 8.5
5 Module Slots
Omega Drill
Mining Speed 37.5
Energy Usage 2250kW (60kw per Mining Speed)
Pollution 225/s (6/s per Mining Speed)
Mining Radius 12.5
3 Module Slots
Vanilla Electric Mining Drill
Mining Speed 0.5
Energy Usage 90kW (180kw per Mining Speed)
Pollution 10/s (20/s per Mining Speed)
Mining Radius 2.5
3 Module Slots
So the omega could probably stand to consume twice as much power (with the same emission factor) and still would be a nice upgrade to vanilla (honestly I'd use it even with same or slightly worse stats than vanilla). The Bucket Wheel uses real world data for power consumption (Bagger 288), so scaling to vanilla wasn't a goal there (even if the pollution fits well IMHO), and with five module slots it's trivial to make it faster or cleaner, or both.
And now I'm wondering, if I'd send you the complete lua, would you consider adding an Omega MK2 for Bob's Mods (that's only visible if Bob's is present?).
