And there was lots of juice still out there, Michael knew. Diesel generators the size of whole towns. Huge LNG plants fat with gas and waiting to go. Acres of solar panels giving their unblinking gaze to the desert sun. Pocket-sized nukes humming away like atomic harmonicas, the heat in the control rods slowly building over decades until someday the whole thing would just go sailing through the floor, exploding in a shower of radioactive steam that somewhere, high above, a long-forgotten satellite, powered by a tiny nuclear cell of its own, would record as the final agonies of a dying brother—before it, too, darkened, soaring headlong to earth in a streak of unacknowledged light.

What a waste. And time was running out.

Rust, corrosion, wind, rain. The nibbling teeth of mice and the acrid droppings of insects and the devouring jaws of years. The war of nature upon machines, of the planet’s chaotic forces upon the works of humankind. The energy that men had pulled from the earth was being inexorably pulled back into it, sucked like water down a drain. Before long, if it hadn’t happened already, not a single high-tension pole would be left standing on the earth.

Mankind had built a world that would take a hundred years to die. A century for the last lights to go out.

The worst of it was, he’d be there when it happened. The batteries were decaying. Decaying badly. He could see it happening before his eyes, on the screen of his old battle-hardened CRT with its thrumming bars of green. The cells had been built to last how long? Thirty years? Fifty? That they could hold any kind of charge after almost a century was a miracle. You could keep the turbines spinning forever in the breeze, but without the batteries to store and regulate the current, one windless night was all it would take.

Fixing the batteries was impossible. The batteries weren’t made to be fixed. They were made to be replaced. You could retrofit all the gaskets you wanted, clear away the corrosion, rewire the controllers till the herd came home. All basically busywork, because the membranes had had it. The membranes were cooked, their polymer pathways hopelessly gummed up with sulfonic acid molecules. That’s what the monitor was telling him with that little-bitty hiccup in the day-to-day. Short of the U.S. Army showing up with a brand-new stack fresh from the factory—Hey, sorry, we forgot about you guys!—the lights were going to fail. A year, two at the outside. And when that happened, it would be he, Michael the Circuit, who’d have to stand up and say, Listen, everybody, I’ve got some not-great news. Tonight’s forecast? Darkness, with widespread screaming. It’s been fun keeping the lights on, but I have to die now. Just like all of you.
