Chapter 137
"That's right." Xun Ying nodded.

"Just replenish the energy once?" White Pigeon asked in disbelief.

Xun Ying continued to nod, "Just add it once."

"Actually, if you want longer battery life, it is not impossible to continue stacking solid-state hydrogen fuel cells." Tesla said.

"Battery?" Baige was keenly aware of something, and said in surprise, "That is to say, what drives this engine is electricity, and you, have the ability to manufacture batteries?"

"That's right," Tesla responded.

"That's the technology of the old era." White Pigeon murmured in a daze, and then he said excitedly, "Can your battery store electricity?"

"It cannot store electrical energy," Tesla said. "Solid-state hydrogen fuel cells do not have the ability to charge and discharge. Its principle is to use hydrogen to generate electricity."

Baige was stunned for a moment, somewhat unable to understand.

Tesla paused, and continued, "You can understand hydrogen as a special kind of oil that can be ignited, and the principle of a solid-state hydrogen fuel cell is to turn this fuel into electricity."

Although both energy storage batteries and fuel cells are batteries, they are actually two things.

Energy storage batteries mainly have the functions of "charging" and "discharging".

The fuel cell uses fuel to "generate electricity", and it cannot be supplemented by electricity.

Therefore, humans in the old era usually used electrolysis of water to produce hydrogen, and then used hydrogen to supplement fuel cells.

It sounds like you're taking your pants off and farting, but in fact fuel cells have many advantages over energy storage batteries.

The first point is that compared with energy storage batteries, fuel cells have the advantage of being relatively smaller and can provide more energy, so they are more suitable for use in mobile machinery.

The second point is that the charging time of the energy storage battery is relatively long, and the hydrogen supplementation of the solid-state hydrogen battery is the same as that of gasoline.

Charging time is also the main problem of many energy storage batteries, which is the main reason why modern electric vehicles cannot replace gasoline vehicles.

The main solution to this problem is superconducting materials, but the cost is too high and it doesn't make sense.

So the solid-state hydrogen battery was born, which solved the main problem of energy storage batteries, so that electric vehicles can truly replace gasoline vehicles.

And compared to the limited resources of oil, hydrogen resources are almost unlimited compared to the amount of human consumption.

Electrolyzed water can be used to obtain hydrogen, while wind power and solar power can be used for electricity, which is truly green, pollution-free and renewable.

Of course, this does not mean that the energy storage battery is useless. In a fixed position, the energy storage battery still has its usefulness.

Moreover, in the hydrogen fuel cell pack made by Tesla, there is also an energy storage battery to store the excess power generated by the hydrogen fuel cell when driving the motor, which is what he calls the "energy recovery system".

The new humans have only been active on this ground for a few hundred years. Obviously, Sky City does not have the technology to electrolyze hydrogen.

They don't even understand the operation mode of fuel cells. In their eyes, those solid-state hydrogen batteries are "waste batteries" that cannot be charged

Therefore, only charging and discharging energy storage batteries can be used, which is even rarer.

The white pigeon nodded, "The electricity in Sky City comes from the sun, so I can understand that heat energy can be converted into electricity. That means, this kind of battery can also drive the engine of the old era?"

"Theoretically yes," Tesla said.

Bai Ge thought for a moment, "The battery life is [-] kilometers, and it can be longer, which means that it can sail for a long time with a single charge.

But if there is only one place for charging, there is no way to go on a long voyage.

You just said, I can buy more batteries to increase the battery life? "

Tesla nodded and said, "The solid-state hydrogen battery pack is composed of 13 yuan batteries, and each battery inside can be replaced.

Just like you used to save oil barrels for long-distance voyages, you can buy more batteries to store on board, and the batteries are smaller than oil and do not take up much space.

In theory, as long as your cargo hold is large enough and you buy enough batteries, it’s no problem to travel around the world and refill your energy again. "

In fact, the battery pack of Xunying can be made bigger and stack more batteries.

After all, the motor is only one-third the size of the previous engine, and the oil cylinder has been removed. This weight is nothing to an empty boat.

But if the battery pack is bigger, the only money they can make in the future is to replenish hydrogen, which can increase the number of times they go to the base.

These thirteen battery packs have been able to exceed the voyage distance that the size of their diesel cylinders can provide them in the past, so they will not feel that the battery life is short.

But for some airlines, they sometimes even have to sail across state lines.

For example, if they go to the Americas, it will take thousands of kilometers to cross the Atlantic Ocean, and a [-]-kilometer battery life will only make them stop in the middle of the sea.

Of course, the floating system of the airship has an independent energy source. If the energy source is really lost, they can still use the sails to sail smoothly and find a place with oil.

These voyages, which they called voyages, lasted for several months and carried special products found only in certain places.

They generally save more oil barrels, and these air dealers actually have refueling places all over the world.

But where electric motors can refuel with hydrogen, there is only a united front, and Tesla's replaceable battery pack design solves this problem.

"Can it still be like this?" Xunying said a little surprised. He didn't hear Tesla mentioning this point.

"I said at the beginning that it was a pluggable design and could be replaced at any time, and you didn't raise the issue of battery life." Tesla said.

Xun Ying nodded, indeed.

Of course, the main reason is that Xunying's airship is too small, and it doesn't have the ability to sail far.

Moreover, the manpower and material resources required for a long voyage are very huge.

The price of oil alone is an astronomical figure. If the ship is too small and the cargo is too small, then the cost of a long voyage will not even be recovered.

So even with that battery life, this airship will basically not sail long distances, and [-] kilometers is enough for this airship.

Of course, Xunying has traveled far in the past, and his cocoa beans, as well as his crew, were all obtained from long-distance voyages.

He also has a larger ship, which is specially used for long-distance voyages, and it docks at a certain port in Sky City for renovations.

Due to the rampant air piracy in recent years, Xunying has rarely sailed far in recent years, only doing business near the Black Sea.

However, the long-distance ship is too big and consumes a lot of fuel, so I bought a smaller one.

Obviously, the same is true of the white dove, but he still has the ambition of sailing.

Although the risk is high and the investment is high, the benefits that can be obtained every time you come back are quite huge.

If this kind of engine can be installed on a long-distance ship, then they don't even have to worry about air theft.

"Is this kind of battery expensive?" White Pigeon asked again.

"Your question is meaningless." Lincheng said, "Is an empty boat expensive? But the benefits it can bring you are hundreds of times and thousands of times.

The battery is not disposable, it can still replenish the hydrogen that is consumed.

The benefits it can bring to you in the future are even more immeasurable. "

Baige looked at Lincheng.

"His name is Lincheng." Xunying introduced, "He is Mr. Tesla's companion, and he also comes from that place."

"Hello." The white pigeon greeted.

Lincheng smiled and nodded.

"The logic of what you said is very suitable to be an air merchant." White Pigeon joked.

Lincheng shrugged, "But it's the truth, isn't it?"

"You are right." Bai Ge said, "Since you are brought by Xunying, then I believe what you said, so let's talk about some practical things. How much do you sell this engine for?"

"We exchanged two electric engines and a solid-state hydrogen battery pack for a ticket to enter Sky City at Xunying," Lincheng said.

Bai Ge frowned slightly, "You mean, such an engine system costs [-] blue rolls? This is comparable to the last small airship."

Hearing the price, Li Ge followed each other with a tacit understanding from the beginning to the end, and everyone could see the joy in each other's eyes.

Three hundred blue rolls, that is, a large carbon coin of [-], if they make a joint venture, maybe they can really win a boat.

"You get what you pay for, don't you?" Lincheng said a modern wise saying, "Besides, if I lower the price, your friends won't be very happy."

"For him, he only needs to be responsible for bringing you in along the way." White Pigeon said.

"But this doesn't affect the value of Sky City tickets, does it?" Lincheng said, "The value of an item depends not only on its cost, but also on demand.

As with my motors, there are only six motors, and there are more than six air dealers here. I think there will always be someone who will be happy to buy these engines at this price, no? "

Baige stared at Lincheng for a moment, then he looked at Xunying, who looked helpless.

He sighed slightly, "You are indeed suitable to enter Sky City and become an air merchant, unlike some people."

Baige glanced at Xunying, "I don't know how to do business like this."

After a pause, he said, "However, I need to see if the goods are as you said."

"Of course, Mr. Tesla will take you there, and he will also help you install it." Lincheng smiled, "Then let's go to the interior of Sky City first."

Dove nodded.

"Bring all your things, we will enter Sky City." Lin Cheng looked at the six people and said.

They fought against their cargo and followed Lincheng. Xunying led his crew to lead the way against their cargo, while Tesla stayed behind with some of Xunying's crew.

It takes a lot of time to install the engine and test the engine, but Lincheng doesn't have that time to spend here, after all, the base may be dangerous anytime and anywhere.

He needs to accomplish his purpose in the shortest possible time.

As soon as I entered Sky City, I sold the motors. Generally speaking, it was a good start.

I hope there will be no accidents after entering Sky City
