“Well, look. You put whatever it is you want . . . tapped, in here.” He indicated a scrawl representing a belljar. “Then . . . well, the science is complicated, but the gist of it . . . let’s see.” He drummed his fingers on the desk. “This boiler’s kept very hot, and it powers a set of interlocking engines here. Now, this one’s loaded up with sensory equipment that can detect various types of energy fields—heat, elyctrostatic, potential, thaumaturgic emissions—and represents them in mathematical form. Now, if I’m right about the unified field, which I am, then all these energy forms are various manifestations of crisis energy. So the job of this analytical engine here is to calculate what kind of crisis energy field is present given the various other fields present.” Isaac scratched his head.

“It’s fucking complicated crisis maths, old son. That’s going to be the hardest part, I reckon. The idea is to have a programme that can say ‘well, there’s so much potential energy, so much thaumaturgic, and whatnot, that means the underlying crisis situation must be such-and-such.’ It’s going to try to translate the . . . uh . . . mundane, into the crisis form. Then—and this is another sticking point—the given effect that you’re after also has to be translated into mathematical form, into some crisis equation, which is fed into this computational engine here. Then what you’re doing is using this, which is powered by a combination of steam or chymistry and thaumaturgy. It’s the crux of the thing, a converter to tap the crisis energy and manifest it in its raw form. You then channel that into the object.” Isaac was becoming more and more excited as he talked about the project. He could not help himself: for a moment, his elation at the massive potential for his research, the sheer scale of what he was doing, defeated his resolve to see only the immediate project.

“The thing is, what we should be able to do is change the form of the object into one where the tapping of its crisis field actually increases its crisis state. In other words, the crisis field grows by virtue of being siphoned off.” Isaac beamed at Yagharek, his mouth open. “D’you see what I’m talking about? Perpetual fucking motion! If we can stabilize the process, you’ve just got an endless feedback loop, which means a permanent font of energy!” He calmed in the face of Yagharek’s impassive frown. Isaac grinned. His resolve to focus on applied theory was made easy, even pressing, by Yagharek’s single-minded obsession with the commission in hand.
