Neither Natia nor the artisans came to Middle-earth from the north to bypass the city of Northfall, so when Donner talked about how to improve the efficiency of freight there, almost everyone had an idea, and it was like a brainstorm. Pen ~ fun ~ pavilion www.biquge.info

However, every idea has more or less problems, either the cost is too high, or the engineering is simply not realized.

For example, Natia proposed that the most burdensome of all freight transport, grain from south to north, that is, from top to bottom, could be built with a long tunnel running through the top and bottom, thrown directly down, and a spring reduction platform could be made at the bottom to support it. But to do so, you first need to dig a 70-kilometer-long shaft, and secondly, the grain packaging can easily fall apart due to high speed or impact during the fall, which is even more troublesome in case of rain.

One craftsman tried to refine Natia's plan, proposing that all the grain be unpacked, dumped down a hill sealed in the mountains, and repacked in the freight yard below, a plan that was also rejected because of the sheer amount of work, and no one could guarantee the dryness of the inside of the rock.

In the end, everyone had to admit that building the city along the surface of the Beiluo Cliffs in order to avoid the intricacies of underground channels seemed to be the only way to go.

For Donner, there is another implication of this conclusion - it seems that at least some of these northbound cities were built at Peter's will.

In fact, Donner himself had an idea: to use a parachute or other slowing down method to transport food. However, this method is not only affected by the weather, but also does not guarantee the direction of landing, and once the parachute hits the north cliff, it is troublesome.

Therefore, this brainstorming slowly entered the scope of how to improve efficiency and reduce manpower work on the basis of the existing Beiluo city.

However, in this way, the difficulty comes back to what Downer has been thinking about for months - motivation. Without a power source, there is no room for automated machinery.

Just when everyone was at a loss, a middle-aged dwarf suddenly spoke up:

"Master Vane, can you take that piece ...... Will you show me another look at that watch?"

"Of course you can......" Donner took the watch from his bosom and handed it over.

The middle-aged dwarf opened the lid of the watch, looked at it for a while, pointed to the bare watch movement, and said to the old craftsman: "Bruno, this is the clockwork you said last time?"

"That's right! It's made using the alloy technology invented by Master Vene. The old craftsman named Bruno replied.

"Hmm......" The middle-aged dwarf closed the lid and said to Donner, "Master Vane, I think that as long as the clockwork is made a little bigger, this problem can be solved." ”

"Tell me about ......" Donner frowned slightly, as if he had seen a glimmer of light.

"Just install a large clockwork on the top of the existing shaft, and when the grain is transported down, the clockwork will be tightened, and when the other supplies are transported up, the clockwork will do the work......," the middle-aged dwarf said slowly.

"I'm afraid you can't make such a big clockwork, can you?" said Donner, shaking his head.

"It's done!" Bruno, the old craftsman, hurriedly said: "You can't do it here, you can do it at home, just ship it over when it's done!"

"Is the spring so good?" Donner still couldn't believe it.

"Master, take another look......" The middle-aged dwarf handed over the pocket watch.

Donner took the pocket watch, opened the cover, and then looked stupid at a glance - he only paid attention to the hand-polished movement, and did not pay attention to the clockwork, but now he found that the clockwork in this watch has been tightened to the tightest, but it is only three or four turns, you know, although this watch does not have a second hand, but it is also almost a little more than a second to cast spring potential energy, just three or four turns of the clockwork, can work for a full twelve days, what is this concept!

That's right, there are far more types of metals in this world than the earth, and they are even more powerful!

Once he figured this out, the problem that had been haunting Donner's mind was temporarily solved.

It's not that there is no power source on this planet, Ball Falls is a ready-made power source, but when the electromagnetic is affected by the magic element, he can't find a suitable energy storage method to use the hydraulic power of the waterfall elsewhere.

However, this problem can at least be alleviated if a strong and durable mainspring can be made – the most primitive and intuitive energy storage device.

"Master Vane......" the middle-aged dwarf continued, "because there are many more materials to be transported downwards than in reverse, so as long as this clockwork is made into a movable one, and when the mainspring is wound, it can be taken out, and it can be used in other places, for example, into a clockwork-driven flatbed car, which can be used to replace the existing manpower ......"

Donner nodded slowly, "What's your name?"

"His name is Mason!" replied the female gnome craftsman, hurrying to help him.

"Very good, Mason, you've got a great idea! So, you're in charge of the improvement!" Donner looked at Mason approvingly.

And Donner, because of his invention of involute gears and alloy technology, has had a great reputation among the dwarf craftsmen of the Far North in recent years, so when he praised Mason in such a positive tone, the craftsman, who had lived for at least a hundred years, was also full of excitement.

"Yes, Master Vane, but in case something goes wrong with the project, can I ask you?" asked Mason, embarrassed.

"Of course, you're in Fog City, you can come to me at any time!" Donner nodded.

"So, you're going now?" asked Natia with a smile.

"Yes, let's go now!" Donner stood up.

"Do you want a carpenter?" said Natia, who had apparently thought of using a clockwork to store energy instead of windmill power.

"Yes, of course, both projects are being carried out at the same time...... By the way, if there are other craftsmen coming over, you can just send them directly to Misty Town. ”

In the plan that Donner and Cynthia have reached, about 3,000 gnomes and more than 100 dwarves will join the construction of the Fog City Engineering Academy. Now, Donner plans to use these people first in the process of building the academy.

"Natia Vida, I need to make a batch of power clockwork at home and send it over, can you help me convey it? "Mason has stepped into the role.

"Absolutely...... Need anything else?" asked Natia.

"Gears! All kinds of gears are needed!" reminded Bruno, the old dwarf craftsman, hurriedly.

Natia glanced at Donner, smiled and said, "Don't be in a hurry to leave, let's sort out the things you need first." ”

For the rest of the day, Donner, along with fourteen dwarf craftsmen, finalized the windmill plan.

The dwarves, after seeing Donner's "whimsy" and jaw-dropping computing ability, looked at him with obvious admiration.

Downer also made several adjustments to the plan according to the metalworking capacity of the Far North.
