The electric generator module is about there now I think. You can timewarp freely, and as long as your other power sources can keep up, you'll not actually burn any karbonite. When your other sources can't keep up, you'll only burn enough karbonite to make up the difference. It also ramps up and down in power gradually, mainly because I liked it, but also because it stops the output numbers flickering. We probably need to work out how much power these things should be generating, and at what efficiency. If we based it on something like gasoline we would be looking at around 47MJ/litre, that's a lot, but we could probably assume that this thing is only 10% efficient even if we were feeding it pure gasoline, and what we are digging up is raw and unrefined and full of garbage we don't need so say, 1MJ/litre? Could possibly lower than that even. 500kJ sounds good to me. So that's my vote for its efficiency, or lack thereof. In terms of actual output power, I'm not sure. Obviously the bigger generators should have higher outputs, but what to base it on? I've been testing at 500kW output, that's a lot, absolutely nothing in the base game comes close to using that much power, but in terms of reality it's about right for a 3.75M part, and there are mods that can make use of that. This is what came up when I did an image search for 500kW generator. So my vote is 500kW, 100kW and 20kW. What are peoples thoughts on these numbers? EDIT: we could also consider slight efficiency penalties for the smaller generators, economy of scale and all that.
