The colonel said, “Xiao[2] Lin, they’re leaning on us to close up shop. Can you work the higher-ups a little more?” I noticed that his attitude toward Lin Yun was not one of a superior to a subordinate, but something more cautious and deferential.
She shook her head. “I can’t speak up in our situation. We must have resolve.” Nor was her tone one of a subordinate to a superior.
“It’s not a matter of resolve. The General Armaments Department is standing firm, but can’t last for much longer.”
“New Concepts wants to come up with something as fast as possible—some theory, at least. This is Dr. Chen from the Lightning Institute.”
As the colonel shook my hand with enthusiasm, he said, “If our two institutions were already cooperating, things might not have gotten to this point. What we’re going to show you today would be eye-opening for anyone in lightning research.”
Just then, there was a marked increase in the brightness of the lights in the room, as if some piece of high-energy equipment had just stopped. The colonel obviously noticed this too, and said, “Looks like it’s charged. Xiao Lin, take Dr. Chen to have a look. I won’t go with you, since, as you put it, I’ve got to have resolve here. You should get in touch with the Lightning Institute in person afterward, to establish a relationship between our two sides. I know former director Xue. He’s retired now, but, just like us, he couldn’t turn his experimental results into anything practical.”
On the way in, I noticed the fully equipped laboratories and engineering shops. That was another clear difference from New Concepts—this was obviously a place for real work.
Lin Yun explained, “Our lightning research is divided into two parts. What we’ll be looking at first is part one: an air-to-ground attack system.”
When we exited the large building we saw a pilot and another operator walking toward a helicopter, and two other people gathering up the thick cable that had just been detached from it. The cable ran straight into one of the buildings where several soldiers were loading a bunch of old oil drums into a truck. It was clear that there had been nothing for anyone to do for quite some time, so they all looked excited now.
Lin Yun led me to a sandbag bunker behind an open space the size of a soccer field, where the soldiers were now unloading the oil drums and stacking them into a cabin-like shape inside a red square. Engines roared in the distance, and then, through the dust whipped up by its propellers, the helicopter rose up slowly, angled its rotor slightly, and flew toward the space above the drums. It hovered over the target for a few seconds, and then a glittering shaft of lightning emerged from its belly and struck the drums. The practically simultaneous clap of thunder caught me off guard and startled me, and right on the heels of the thunder were several more dull noises, the explosions and fire from the residual oil in the drums. I stared in shock for a while at the black smoke wrapped around dark flames, and then asked, “What are you using for energy to produce the lightning?”
“The National Laboratory for Superconductivity at CAS has developed high-energy batteries made of room-temperature superconducting material. They can store lots of power simply by flowing current continuously through a large loop of superconducting wire.”
Then the helicopter began to discharge to the ground, for a longer duration this time, but at a low intensity. A long, thin arc connected ground and helicopter, snaking through the air like a dancer’s graceful curves, or a windblown strand of UV-emitting spider silk.
“This is a low-intensity, continuous release of the superconductor battery’s residual energy. The battery is highly unstable and not very safe, so ordinarily it can’t store a charge. Let’s wait a bit—this will take at least ten minutes. It’s a nice sound, isn’t it?”
The power release wasn’t loud, but it sounded like fingernails on glass, and gave me goose bumps.
I asked, “How many times can you repeat that high-intensity release?”
“That depends on the number and capacity of the superconductor batteries. This helicopter could manage eight to ten, but we can’t drain the residual power in that way.”
“Why not?”
“People would protest.” She pointed to the north, where I saw a group of luxury homes not too far from the base. “The base was originally meant to be farther from the city, but for various reasons it was built here. You’ll see later on that noise nuisance isn’t the only consequence of this mistake.”
When the residual power was drained, she took me to look at the equipment on the helicopter. Unfamiliar with electronics and machinery, I didn’t understand much, but I was deeply impressed by the cylindrical superconductor batteries.
“So you say this system isn’t successful?” I asked, inwardly amazed at what I’d just witnessed.
“First Lieutenant Yang is an attack helicopter pilot with the Thirty-Eighth Army Aviation Regiment. He is most qualified to draw a conclusion.”
I thought about the ball lightning eyewitness, but the man in front of me was a little younger. He said, “The first time I saw this, I was really excited for a while. I felt like I couldn’t praise it enough, and that it would greatly increase the ground attack capabilities of our armed helicopters…. Basically, I was as excited as a World War I pilot seeing one of today’s guided missiles! But I soon realized that it’s nothing more than a toy.”
“Why?”
“First, the attack range. No more than one hundred meters from its target, or it won’t release electricity. A grenade can go a hundred meters.”
Lin Yun said, “We tried everything, but that’s the range limit.”
This was easy to understand. The energy in the superconductor battery was far too insufficient to produce natural lightning in an arc several kilometers long, and even if this energy could be generated by other means, like nuclear reactions, no existing weapons platform—be it armed helicopter or destroyer—would be able to withstand such an energy discharge: when shooting lightning, they’d end up destroying themselves first.
The lieutenant said, “There’s another thing that’s even more ridiculous… but I’ll let Dr. Lin explain it herself.”
Lin Yun said, “You’ve probably already thought of it.”
This time I had. “You’re referring to a discharge pole?”
“Yes.” She pointed to the red square area with the oil barrels, still burning. “We gave that red area a negative charge of 1.5 coulombs in advance.”
I thought for a moment. “Would it be possible to use another means, like radiation, to induce a negative charge in the target area from a distance?”
“That was one thing we considered from the start, and we began R&D on a long-range electrostatic charger concurrently with this discharge device, but the technology was very difficult, particularly under combat conditions, where effectively fighting a moving target requires completing the charging process within roughly one second. Under current technical conditions, that’s practically impossible.” She sighed. “Like the lieutenant said, we created a toy. We can demonstrate it to scare people a little, but it has no actual combat value.”
Then she took me to see the next project. “You’ll probably be most interested in this,” she said. “We’re producing lightning in the atmosphere.”
We entered the high, wide-roofed building, which Lin Yun told me was converted from a large warehouse. A row of floodlights on the high domed ceiling illuminated the vast space, where our footsteps echoed, and Lin Yun’s voice produced a pleasant echo as well.
