I am not the person you were replying to, but my position is that when you plop down a rolling machine, you're not done.
At the very least, you have to connect it to your power network. Having to build another engine, or some gates, is simply an extension of that. I don't know how facades even come into this.
In the context of my previous posts, it is highly likely that I am, in fact, done when I've placed the rolling machine. My preference for building, especially early/mid game, is to generate enough power to refill a redstone energy cell used as an intermediate buffer between my machines and my engines. My machines can, at any given point, pull more output than my engines can generate and I do not feel it is necessary to add more power generation to the system until the REC cannot fill up in a timely fashion, nor keep up with passive draw. As a result, I eliminate passive draw from the system (obvious methods, already discussed) at this point in my game as an inefficiency that that I'm unwilling to pay for.
Re: facades. I was attempting to introduce levity, because, really, if you're dropping 80000 mj on a pair of iron conditional gates to keep a rolling machine from burning energy then 1) what's another..what, 600? to hide the power lines, and 2) as I've said, you already recognize the problem that passive power drain represents in terms of a cost/reward failure and you're just quietly working around it. Honestly...if you truly believed it was a valid cost, you'd never apply a gate to it.
Really?
I suppose that needs clarification and stuff. I don't feel that nuclear reactors are complicated for a couple of reasons. The first, and most important, is that whenever you want to build one you can take your specifications and get an exact system from ye-old-internets, and in that case it just becomes a matter of cut and paste (well, drag and drop...you know what I mean, I think). Until the underlying rules change, making a reactor is no more complicated or difficult than opening a children's book and identifying an animal from a lineup.
The second, slightly less important reason, is that the rules of a nuclear reactor aren't all that complicated. (Fuel) produces energy but generates heat. (Fuel) next to (fuel) generates more energy than (fuel) that is separated. Surround (fuel) with cooling stuff, that which touches interacts. Fill empty spaces with useful items to help cool reactor, and so on. In the interests of full disclosure, I haven't built a reactor so I am not familiar with all of those rules. Just a subset that can be picked up while listening to LP's in the background while working, hoping to pick out another interesting idea to steal. I don't use industrialcraft for much of anything, so feel free to disagree with my assessment of reactors with an obligatory 'until you've built one...'. I can understand why. I think that the position is still essentially correct, even without firsthand experience, because the underlying rules of the reactor aren't all that complicated and don't seem to introduce enough variables to the process to make me feel it is difficult.
And now..back to your regularly scheduled squabbling.
