They didn't know yet if they'd need to expand beyond that, but they were prepared to. Dad told us all this on the train. He drew a diagram and showed that six cables was probably the most you could put down without hitting the point of diminishing returns. Part of it was land area, part of it was economics; it all had to do with something called Elevator Theory.
By the time we got to Beanstalk City—that's what everybody calls it, but that's not its real name; it's really named after Sheffield Clarke, the English engineer who designed and built the whole thing—all of us were excited in spite of ourselves. Even Weird had stopped being a jerk long enough to ask Dad questions. And Dad answered honestly.
I was excited, but I was also getting a little scared too. This wasn't going to be like an airplane. An airplane, you knew what was holding you up. This was different. Nothing was holding you up. What if it broke? I knew it couldn't, but what if it did anyway—?
We arrived at the beanstalk at ten in the morning. First we rolled across a big plateau with dark mountains all around. There were a lot of warehouses and industrial buildings—and tube-towns too. Everything looked big and new and shiny—except for the parts that were small and cheap and dirty. The last twenty miles we passed a whole bunch of parking areas and hospitality structures and hotels and tacky little side businesses—and then abruptly, that all stopped and we were riding through what looked like a big park. Weird said this was the safeguard zone around the beanstalk.
For security reasons, they don't let anyone drive right up to the elevator. The closest you can approach by car is one of the official arrival areas. These are all at least fifteen kilometers away from Terminus. All traffic from there is by shuttle-train. I suppose a terrorist with a rocket-launcher might be able to do some damage from that distance, but if somebody really wanted to assault the beanstalk, they wouldn't do it with a rocket-launcher anyway. Dad said that almost the entire Ecuadorian economy is based on the beanstalk now, and they're a world power too, and a sponsoring nation of the Colonization Authority, so they don't take any chances with Line security.
The sky had gone all hazy gray and overcast—there was a tropical storm heading in from the Pacific—so we couldn't see if the Line went all the way up to zenith or not. But all of the beanstalk's lights were on and that made it very bright against the grungy clouds. We could even see the flashing lights of vehicles sliding up and down the Line. I started wondering how often lightning struck the cables and what kind of trouble it could cause to the people in the elevator cars. Despite the high gloom, the weather was still sweltering. Dad said they never have cold days anywhere on the equator, but it was definitely windy outside; we could see the trees whipping back and forth, and occasionally big palm fronds would go tumbling by. Weird said there was nothing to worry about; the Line was secure for wind velocities of up to 625 kph.
Dad opened the tour book he'd bought that showed how the base of the Line was surrounded by cargo facilities, terminals, parks, tourist sites, stadiums, theaters, and a whole webwork of highways, tracks, and canals. The widest canal circled the beanstalk—Weird said that all of the bridges over it were retractable, in case terrorists or someone tried a ground assault. Airplanes weren't even allowed to fly within fifty klicks of the Line without special permission. He said the Ecuadorians were very serious about this; they once shot down somebody's Lear Jet and there was a big lawsuit about it.
When you get close enough, the bottom of the Line starts rising up over the horizon like a big white mountain. It spreads down and out and out and just keeps getting bigger and bigger the closer you get. And it takes a long time to get. A half hour at least. The top of the cone part is over two kilometers high. At the apex there's a ring around the Line, an observation tower where you can view the surrounding countryside or just watch the Line-cars go sliding up into the sky.
Closer still, you can see that there are wide gaps along the bottom of the cone—like a tent just a little too short for its ropes. The train slides in right under the edge. And then everything gets real bright.
Terminus is more than a launching station, it's a domed city—bigger than enormous, twenty klicks across. Think of a gigantic tent that uses the three cables of the beanstalk as the central mast, the tent fabric is made out of the same monofilament stuff as the Line, and all of the supporting cables are actual beanstalk filaments anchored off axis for additional stability. So once you're inside the tent, you're actually inside the beanstalk. It's a whole other world. Distances don't look the same. You can't tell how near or how far anything is. And everywhere, the filaments of the beanstalk spread out like rays of the sun, stabbing into the ground and anchoring themselves deep in the bedrock.
The top of the Terminus dome goes up so high it fades away in the distance. It's almost like someone took the meteor crater and turned it upside down over everything like a gigantic cup, only bigger than that. Terminus dome is so big it has its own weather. They get clouds and fog, and sometimes they even get little rainstorms. But the outer surface of the tent is painted with solar crystals to generate power for the air-conditioning inside, so it's mostly comfortable.
And of course, the three main cables of the Line are visible from everywhere. They're all lit up like a big bar of sunlight, so everything inside is as bright as it is outside—and that's pretty bright, because it's right spang on the equator. There's a line drawn across Terminus so you can tell where the equator is; you can stand in both hemispheres at the same time if you want to.
The actual cables of the Line were a lot thicker than I thought they would be. And they were spaced quite a distance apart; it looked like at least a kilometer, maybe more. There was a lot of traffic on them too. There was always at least one car inside the dome going slowly up or down on each of the strands. They don't really get up to full speed until they get out of the dome and out of the thickest part of the atmosphere.
I guess we did a lot of gaping. Everyone did. That's because Terminus dome is like no other place in the world—at least not any place I'd ever been. It's like an amusement park and a shopping mall and a factory all scrunched together. Everything was stacked on top of everything else. Towers and balconies and gardens and waterfalls everywhere. And rides and restaurants and all kinds of theaters and stores and clubs. And signs and lights and music and a constant roar of noise. We could even hear it inside the train.
The train station is elevated, so as the train pulls into the tent you can see the whole interior of the station spread out below like a big jumbled toy box, and everybody all over the dome can see the SuperTrain too. It's really impressive. But when you get off, Weird pointed out, you're still in a holding area. You have to go through multiple security gates where you get scanned and photographed and inspected, and then only when they're satisfied that you're not some kind of terrorist or madman do they let you go down the ramp into the city. Stinky was already pulling at Dad's arm. "I wanna go on the rides—" But Dad shook his head and said, "We're about to go on the biggest ride of all, kiddo."
We were each responsible for our own luggage. Dad had insisted that we travel light. When we turned in the rent-a-car in Mexico, we left behind everything we weren't going to need for the trip up to Geostationary and back, and that meant most of Stinky's toys—not the monkey, though; Dad insisted Stinky bring it after he'd spent all that cash—and the rest of the stuff like bathing suits and towels and dirty clothes and extra jeans. We just put it all in a big box and shipped it home.
Weird and Stinky and I had all our stuff in backpacks. Dad had his stuff in a rollaround. Stinky had half his clothes in his own backpack and the other half in a smaller one on the monkey; he held its hand and chattered at it like they were married. It waddled beside him like an obedient child with a full diaper. It was almost cute. I said they looked like twins, which got a laugh from Weird and a dirty look from Dad. "Well, it looks just like him—" I started to say, but Stinky heard that and started crying, and suddenly he didn't like his monkey at all anymore. "Does
not look like me!" he said, kicking it away. Of course, the monkey came scurrying right back to him, so he kicked at it again—the monkey jumped out of the way and Stinky fell on his butt. And started wailing like an injured banshee. People were staring at us now, some of them angrily, as they threaded their way around us. We were blocking the access to the exit gate.
Dad got really angry. He scooped up the monkey and thrust it into my arms. "You started this, Charles. You take care of the monkey!" Of course, the monkey didn't want to be carried. Not by me, anyway. Stinky had thoroughly imprinted it, so all it wanted to do was get back to him. It squirmed and whimpered and trembled and kept trying to wriggle out of my arms. "Stop it!" I said firmly, but the monkey ignored me. I tried feeling around for its off switch, but the monkey started giggling as if I was tickling it. Then it started screeching.
The noise got Stinky's attention. He started screaming at me, "That's my monkey! I want it back! Give it back!" Dad tried to calm him down, but Stinky kept squirming and crying and screaming, just like the monkey, and finally he wriggled out of Dad's grasp and came and grabbed the damn thing out of my arms. I couldn't believe it; they really were twins. I stood there, staring at him, wondering why any kid's parents would ever let him survive long enough to reach adulthood. There must be something about parents—some kind of chemical trigger in the brain—that keeps them from strangling their own children.
I started to say something about that, but Dad just glared at me and said, "Why don't you keep your mouth shut for a while, Charles. You've said enough for one day."
Right. Stinky threw a tantrum and it was my fault. If I'd have been Dad, I'd have put that damn monkey into the nearest trash can. In pieces.
They pushed on through the gate, leaving me staring after them astonished, wishing I could be an orphan for a while. Anything would be better than this. Maybe I should just divorce them all and the hell with it. The more I thought about it, the more I liked that idea. I could look up the procedures on the net, I'd done it before, but I'd never followed through. Maybe this time I'd stay angry long enough. In the meantime ... I reshouldered my backpack and followed. Like I always do.
From the train terminal, there's a shuttle-train on a sort of circular track that winds back and forth and in and out of everything all around the Terminus dome. It's free, and you can get on it anywhere and just go around and around all day long. The shuttle goes through at least a dozen hotels and a couple of big shopping centers and a several huge museums and an amusement park and over an indoor lake and through a whole bunch of permanent apartments and offices. There are theaters and clubs and parks and restaurants everywhere and I don't know what else. If you can imagine it, it's probably here.
Climbing up the inside of the tent, there are at least fifty stories of balconies and terraces all of them piled up high like a man-made crater wall. Dad said someday it'll be a hundred and fifty stories of apartments and offices and stores on the inside. And probably more outside too.
Dad had a book about the cable, and he started pointing out stuff and explaining it to us as we went. Even though I was still angry, some of it was kind of interesting. He said there were even more city levels higher up the Line, some already developed, some awaiting future expansion. In fact, there were public parts of the structure all the way up to six kilometers, because some people like living that high; some of the industrial levels went even higher. There were a lot of weather stations too. The meteorologists loved the Line because it gave them a real-time core sample of the atmosphere. And there were all kinds of factories that needed high altitudes for various processes and stuff. Above that, there were observatories and broadcast stations up the entire length of the orbital elevator. So it wasn't all empty cable.
There was no shortage of vertical space, and there probably wouldn't ever be, at least not for a long, long time. Dad said that the industrial development of the cable would eventually prove more important than the transportation aspects, because the beanstalk had effectively tripled or quadrupled Ecuador's usable land area. In fact, they'd be dropping new cables to handle the increased traffic long before they used up all the available vertical space on the existing lines.
Dad said that the Orbital Elevator Corporation was planning to start dropping the first of the next three cables in a few months. Each new cable dropped would create another triangle and another area of interior space. When I asked how that would affect Terminus, Dad had said that Terminus would get even bigger. The area covered by the tent would be expanded—quadrupled, at least—so obviously the ground-level expansion was already planned for too.
But by then, the Kenya cable would be up and running and that would be serious competition, so there wouldn't be as much pressure to grow as fast, although Dad said that the Ecuadorian cable could probably lower their fares and shipping costs by then, because so much of their initial investment would already have been amortized, so they could probably give the Kenyan group a pretty hard time.
Dad said there was also a Singapore-Malaysia investment group preparing a cable of their own, and British Canada was dropping a cable down into the Pacific Ocean, just south of Christmas Island. That didn't make sense to me, but Dad said there were a lot of military and scientific reasons for having a cable of your own.
There was something about the way he said that last part. "Do you think there's going to be a war?" I asked.
He looked at me with a sad look in his eyes. "I hope not," he said, "but sometimes I think it's already started and we just don't know it yet."
ALL ABOARD
It wasn't too hard to find a ticket lobby. There was this big circular balcony all around the cables. It was as wide as an avenue, it had two levels, and there were check-in counters on both levels. It was high enough above the floor of Terminus that you could look down over the railing and see the big well where the cables disappeared into the Earth. You could see everything, even how the cars were loaded and moved into position for launch. We all wanted to look, but Dad insisted we get our tickets first.
The ticket counters on the lower balcony were only for day-trips up to One-Hour. That was real popular with tourists who wanted to visit the beanstalk and who wanted to go into space but who weren't planning to go all the way up to orbit, which was a much longer trip. There were elevators leaving for One-Hour every five minutes.
One-Hour was open twenty-four hours a day, but we had to go to a different line. Tickets for Geostationary and even farther out, like to the launch stations beyond, were sold on the top level. Those cars launched every fifteen minutes.
Dad had made reservations for a 2:15 elevator, but we were early. The woman behind the counter had a shiny brown face, and she kept smiling at Stinky like he was her own little boy. She suggested that we go straight on up to One-Hour now and see all the sights up there, and then we could catch our reserved cabin on the 2:15 car when it stopped at One-Hour to pick up passengers. That way we could leave almost immediately without any waiting and we'd get to see everything up at One-Hour too. Because of the storm coming in, traffic up the elevator was heavier than usual, she said, so it was probably a good idea to leave now. Dad agreed and so did the rest of us, so the woman rewrote our reservations. She scanned our IDs and then gave each of us our own boarding cards.
She asked if we wanted to check our luggage, but Dad said no. We didn't have that much and we'd prefer to keep it with us. She had a pretty smile and she made us all feel a lot friendlier—like we were actually going to have fun for a change. She gave each of us an elevator badge to wear. I started to shove mine in my pocket, until Weird pointed out that it was also a life-monitor and a locator chip and a beeper-communicator. We had to wear our badges at all times, Weird said.
After that, Dad took us back over to the edge of the balcony to look at how the cables worked. The three cables of the Line plunged straight down from the very top of the tent each into its own separate hole in the floor of the station. They were as big around as buildings. Bigger. Dad said
each one was as thick as a baseball stadium. The bottom of the Line looked like three huge pillars from God with a big open space between them—enough for another dozen stadiums. Probably more.
This wasn't the real bottom of the Line, of course. That was anchored four or five kilometers underground. Above us, below us, all around us, all the separate filaments of the cable were peeled off into underground tunnels and threaded down into the bowels of the earth, where each one was knotted around a couple zillion tons of basalt or whatever. They couldn't pull loose. Every filament was separately anchored, some as far as fifty klicks away so there would be a firm anchor for the Line even if there were a massive earthquake here.
From our vantage point on the balcony, we could see everything. Dad pointed out the details of this and that as happily as if he'd built the Line himself. He explained the purposes of each of the different tracks, talked about what the lights meant, and made sure we noticed all the smaller cables running down the sides of the big ones.
As we watched, an elevator car slid down one of the cables into a reception bay; at the same time another one popped up on the other side of the same cable. On the next cable over, a pair of linked cargo pods came sliding down, direct from orbit; they had a Lunar insignia painted on them. As they slid out of sight, a loaded cargo container rose up to balance them. "Look! That one's going straight to the moon," I said to Stinky. We watched as it rose up and up and up until it finally disappeared through the roof.
That's when it hit me. That we were going up too. This wasn't another one of Dad's didn't-happen promises. This was for real. And that's when I started to feel very nervous. Especially about the stuff Weird had said. I was beginning to think he might be right. This whole trip—it wasn't normal. Not for Dad.
I wished I knew how to ask Dad to reconsider, but I knew whatever I said, he wouldn't change his mind. Certainly not after traveling all this way. And Weird and Stinky were so hyped up about the elevator, they probably wouldn't let him reconsider anyway. I would have waited down here at Terminus for them, but I knew Dad would never agree to that either—and I didn't dare ask.
