"The contact end needs to be directly exposed to the complex external environment, and the best contact end of the entire Cassini station is the communication tower, which is the highest position and has been struck by lightning the most." Dai Yue said, "So one end of the entire power supply system should be placed on the communication tower, and the top of the structure communication tower is a hemispherical radome, which will be a good contact." ”

"But what do we use?" Zhao Mumu asked, "Do you use a coil?" Put a coil on it? ”

According to Mu Mu's idea, using a coil would be a good means, in the end they want to get power from the clouds overhead, and the coil is a very traditional wireless power transmission method, using electromagnetic induction or magnetic field resonance principle to obtain energy from the electric field of thunderstorms.

"Unrealistic, we can't control how often thunderstorms change, and we don't have a coil big enough unless you have a way to rub one out with your hands." Dai Yue shook his head, "Remember, this contact end is to be directly exposed to lightning, to put it bluntly, it may be struck by lightning, the lightning on Titan has tens of billions of volts of high pressure, what is split and exploded, the coil cannot withstand it, you have to pay attention to this is Titan, to work normally in this hellish place, in such a harsh environment, there is only one way." ”

"How?"

"The simpler, the better." Dai Yue replied, "It must be simple enough, so simple that no matter how you split it, it can't be broken." ”

"Then go up with a stick." "A metal stick can't be broken no matter how you split it." ”

"It's going to have a higher melting point." Stong added, "You can't just melt it. ”

"Then remove the ship's whip antenna base." Mu Mu thought for a moment, "The tungsten core is silver-plated, it should be able to meet your requirements." ”

"The next step is the transmission network, and to build the transmission network, we have to remove all the HTSC (high-temperature superconducting cables) on the spacecraft, whether it is DC cables or AC cables, and then connect them in parallel into a whole transmission line." Dai Yue continued, "Connected to the communication tower. ”

The internal pipelines of the "Hades" spacecraft are all yttrium-barium oxide superconductors and lead-strontium-yttrium oxide superconductors, which are quite aging lines now, after all, it is an old ship, and the new spacecraft uses graphene superconducting technology.

"Is the current carrying capacity high enough?" Stern asked.

"I don't know." Dai Yue shook his head.

"Isn't the current carrying capacity of superconducting cables infinite?" Ge Zi asked.

Shi Teng smiled, "Xiao Zi, how can there be a cable with infinite current carrying capacity in this world?" ”

"Under normal circumstances, the current carrying capacity is related to the material thickness of the cable and the working temperature, superconductors also have a critical current, and they will quench if the critical current is exceeded, and the current carrying capacity of the superconducting cable inside the Hades spacecraft is 30 to 50 times that of ordinary polyethylene insulated copper core cable, about 20KA per square centimeter." Dai Yue explained, "The instantaneous power is extremely high when the ignition of the fusion reactor is started, so although the resistive load of the superconducting cable is very low, the inductive load will be very high. ”

"How big is the current in a thunderstorm?" Mu Mu asked.

"The instantaneous current is more than half a million amperes." Stong replied.

Mu Mu was taken aback and was speechless, "Can this hold up?" ”

"I can't hold it." Liu Peijia said, "500,000 amps, damn, this dog's electric current." ”

"What happens if the current exceeds the current carrying capacity of the wire?" Ge Zi asked.

"Heat, excess energy is emitted in the form of heat." Dai Yue said, "It will produce ultra-high temperatures in a very short period of time, and then ......"

"And then there's 'Bang'!" Liu Peijia put his hands together and was startled.

Both girls shrank back.

"So we can only collect as many superconducting cables as we can and concentrate them, and the larger the cross-sectional area of the cable, the greater the current carrying capacity." "Try to make them last 0.01 milliseconds before they are melted by a thunderstorm, we just need it to work for 0.01 milliseconds, that's the only way." ”

Ge Zi felt that this was too unreliable.

Dai Yue shook his head and said that we are all already shipwrecked crew members, so we can only use whatever we have, where is there any absolutely reliable method?

"In order to ensure reliability, we have to remove all the parts on the transmission network, we can't have any interfaces, we can't add any resistance, and if we add a joint, we can increase the chance of failure by 200 percent." "So the contact end of the transmission network should be directly connected to the igniter." ”

As soon as these words came out, Shi Teng, Zhuozhi and Liu Peijia were all startled.

According to Dai Yue's concept, the final product is like this: one end of the wire is connected to the communication tower, and the other end is directly connected to the ignition of the fusion reactor, and the mine is directly introduced into the reactor, and the original backup power supply and control system are all removed.

He just said that this is purely funny, and it is a dead end.

But the plan he came up with is still the same thing.

"Just let the lightning penetrate the igniter?" Liu Peijia asked, "Can this work?" Won't the reactor blow up? ”

"The igniter of the fusion reactor is an excited solid-state laser, which can be activated as long as the energy reaches a threshold, and this thing is a bomb, as long as the fuse is strong enough, whether you insert a detonator or a sky monkey, it can explode." Dai Yue said, "Theoretically, it is also possible to directly use lightning strikes. ”

The engineer who designed the igniter back then was so rude.

"Yes...... But how can this be controlled? Zhuo Zhi asked, he really couldn't think of how to control such a set of Heavenly Thunder Tribulation System.

"How do we control high voltage in general?" Dai Yue's eyes slanted.

"Usually with relays." Wisdom said, "Use weak electricity to control strong electricity, and use low voltage to control high voltage." ”

Relay in industrial control is the most basic control system, simple and traditional, used for hundreds of years is still in use, two sets of circuits, with relays, people do not have to personally contact the dangerous high-voltage transmission line, Dai Yue designed the transmission network that may be the highest voltage and maximum current in history, but how to control this crazy thing? Do you want to put a power brake in the middle of the line? Let Lao Shi hold the gate, and as soon as the thunderstorm comes, let Lao Shi pull down the gate.

Old Shi: Why do you send me to death every time?

Pulling off this electric switch, some people will manage the fusion reactor, and the other part will collect the ashes of the old history.

"We're out of control this time." Dai Yue was very simple, "Dismantle all the control systems, we can't control this line, it's impossible to control, and it doesn't need us to control it." ”

"Without a control system, how do I start and how do I terminate?" Wisdom couldn't figure it out.

"Start when there is thunder." Dai Yue replied, "As for termination, it will inevitably terminate itself. ”

"Why?"

"Because this line is 100 percent going to blow up." Dai Yue spread his hands, "Won't it be terminated if it is blown up?" ”
