From Propulsion City To Multiverse

The underground world of the West Sea is surging.

At this time, Olvia and Robin had passed through the shadow channel and came to the cloud realm.

After more than half a year of action, the People's Revolutionary Federation has absorbed as many as 1.73 million people from the Flower Country, of which 1.4 million were placed in the Tianyun Federation, and the remaining 330,000 were placed in the Food Kingdom.

The arrival of the population of these countries of flowers quickly filled various man-made empty islands, plus the 15 natural large-scale empty islands controlled by economic penetration. At this time, the total population of the Tianyun Federation has reached 2.13 million.

At present, the Tianyun Federation has a total of 67 empty islands, of which 32 are artificial and 33 are natural.

Its control area is divided into three major areas, namely the Yunjing area, the Shandola area, and the Kunlun virtual area.

The increase in population and territorial airspace naturally requires an increase in the size of the standing army. Currently, the Tianyun Federation has a total of 60,000 standing armies, totaling 12 regiments.

Of course, the size of the army of 12 regiments is actually obviously exceeding the standard for the current Tianyun Federation.

Because of the combat effectiveness of the soldiers of the People's Revolutionary Federation, with the blessing of Jijia, the per capita combat strength reached the major general level and started.

With a battalion of 500 people, without external support, it was an easy task to capture the middle kingdom on the sea.

And 12 regiments of 60,000 people, even powerful countries such as the Land of Flowers, Elbaf, and Alabasta, are not enough to resist.

At present, the troops stationed on each air island are usually 1 battalion per air island.

Even Yunjing, Shandola, and Kunlunxu, which are the capitals, are only one regiment of troops.

At present, the strength of the Tianyun Federation is still 4 regiments.

But such a large-scale force is not for defense, but for offense, and these forces are reserves.

In addition, there are martial arts halls, recruit training camps, and militia reserves. The People's Revolutionary Federation is basically a state where all the people are soldiers, which can be called the extreme of martial arts.

the other side.

The brand-new battleship Wang Gao personally designed, Qunxingxing, also came to the most critical place.

Dr. Moon and Dr. Faraday were abducted from the kingdom of the future,

He is also helping Wang Gao to design a group of star warships.

Just three people, plus a group of researchers, are still stumped by the core problem. As a spaceship, the prototype of the star is the Ark Proverbs, but the scale is much larger.

The original design dimensions of the Ark Proverbs are roughly as follows:

The main part of the spacecraft: the height of up and down is 125 meters, the length of front and rear is 173 meters, and the width of left and right is 93 meters.

The length of the front and rear, if the angle of impact is added, can reach 190 meters; the width of the left and right, if the propellers on both sides are added, it can reach 174.6 meters.

The total volume reaches 164,000 cubic meters. Although it is not entirely made of gold, the proportion of gold in it is very high.

In the original design of Ark Proverbs, wood, steel, etc., accounted for about 98.8% of the parts, and the remaining 1.2% of the parts were made of gold.

Among them, 98.8% of wood and steel and other parts weigh only about 15,000 tons; while the gold parts, which only account for 1.2% of the volume, weigh 9,304 tons.

This shows how huge the gold reserves of the golden city of Shandola are.

After Enilu built the Ark Proverbs, there are still a lot of them left, and the total reserves are more than tens of thousands of tons.

Of course, the design of the original Ark Proverbs must not be copied. After all, gold is not steel. Even if it can be excavated at the bottom of the sea, it is not conducive to mass production.

What's more, the role of gold in the Ark Proverbs is that it is used as a conductor and storage, and gold is not the best conductor material.

Among the currently known materials, the materials with the best conductivity are silver, copper, gold, and aluminum in order.

The key factor that determines the electrical conductivity of a material is the resistivity, and the lower the resistivity, the better the electrical conductivity of the material.

The resistivities in these four materials are: silver 1.6, copper 1.7, gold 2.4, and aluminum 2.7.

Therefore, the improved version of the star warship uses copper wire as the core material of the circuit and motor.

Another change, and that is the flight mode.

In the fixed impression, the Ark Proverbs has propellers and oars, and many people will think that this spaceship relies on propellers and oars to fly to the moon.

In fact, the core power of the Ark Proverbs does not rely on propellers and oars, but on the anti-gravity generated by N hydrogen particles.

This is also the hull of Ark Proverbs. It looks like a ship with a large wine barrel. The reason is that the huge barrel part stores a large amount of liquid rich in N hydrogen particles inside.

When Anilu started the Ark Proverbs in later generations, there was a very special scene, that is, he sat on the golden power generation seat and used the ability of the Thunder Fruit to ionize the "big water bottles" inside the Ark Proverbs through electric current, and then the chimney spit out Lots of thunderclouds.

In fact, these "big water bottles" are containers for storing liquids rich in N-hydrogen particles.

Through the ionization of different voltages, a large number of thunderclouds, cumulonimbus and floating clouds can be generated.

Moreover, in the large barrel cabin, there are not only liquid storage bottles, but also floating cloud airbags and battery storage batteries. The floating cloud airbags are filled with floating clouds rich in N-hydrogen particles.

When energized, the N-hydrogen particles become highly active, and the strength of the antigravity they generate increases accordingly.

There is not only one floating cloud airbag, but because of the composition of 500, the control of the overall anti-gravity strength of the spacecraft can be achieved through the power-on ratio of the floating cloud airbag.

This is the core motivation of the Ark Proverbs.

As for the propeller and the propeller, they are actually useful. These two systems are mainly used to control the flight attitude and direction.

In addition, after entering the atmosphere, or going down to the sea, it can also be used as an important means of propulsion.

The Ark Proverbs is clearly a multipurpose ship.

As another descendant of the moon people, the future kingdom, in fact, there is still a part of the technology of the Ark Proverbs, but it is not complete.

For example, those flying balloons made by Dr. Tsukimami use part of the floating cloud airbag technology of the Ark Proverbs.

Qunxingxing also uses a built-in floating cloud airbag, but Wang Gao, Dr. Yuejian, Dr. Faraday and others encountered a thorny problem with the storage battery.

That is, the current storage battery density is not high. If the person without the ability to ring the thunder fruit continues to discharge, they will not be able to run for very long, and it is enough to go back and forth to the moon.

And the electric energy released by the capable person is not unlimited, and physical strength is a fatal problem.

Even a calorie heart can't support more than 10 ark mantras.

What's more, one group of stars is equivalent to three arks.

That is to say, those with the Thunder Fruit ability can maintain a maximum of three star-level ships, and currently in the Yunjing shipyard, a total of three star-level ships have been built.

If you want to increase the scale of star warships in the future, you will face the situation of no electricity available.

At present, Wang Gao has three solutions.

The first idea is to increase the unit power storage density of the storage battery, so that it can be charged once and used for several months.

It is a pity that although he and Faraday continued to improve the power storage materials, they only increased the power storage density by about 1.7 times from the original foundation, which is still far from the envisaged goal.

The second idea is a bio-generator, which uses the genes of electric eels, fur tribes, air island shellfish and other organisms to adjust artificial creatures specially used for power generation.

There is no problem with technology, and the single-unit power generation can reach 3 megawatts, that is, a large amount of high-energy food is needed.

In fact, the lunar people also thought about this plan back then. The fur tribe is a genetically modified genetically modified organism under such a background.

Even if Wang Gao has the genetic foundation of the fur tribe, the thermal efficiency of the adjusted bio-generator is still not as good as that of the internal combustion generator.

The third idea...
