Solar system.

The stars of the nine planets revolve around the core of the galaxy like a moon, like loyal guards that remain unchanged for eternity.

The only light source in the solar system emits endless light and heat, dispelling the eternal darkness of the boundless universe and illuminating the entire galaxy, it burns itself, igniting the solar system and the civilization flame of the earth.

The Sun is the central body of the galaxy, accounting for 99.86% of the total mass of the solar system, and the remaining 0.14% of various celestial bodies and interstellar dust revolve around the Sun, and the Sun revolves around the center of the Milky Way.

It is a star intertwined with hot plasma and magnetic field, with a diameter of about 1.39 million kilometers, equivalent to 109 times the diameter of the Earth, and a volume of about 1.3 million times that of the Earth.

From the point of view of chemical composition, about three-quarters of the mass of the sun is hydrogen, and the rest is almost helium, which uses nuclear fusion to release light and heat into space, which is the well-deserved energy heart of the solar system!

In recent years, with the development of earth science and technology and the huge demand for electricity, the photovoltaic industry has grown rapidly, and the utilization rate of solar energy in countries on the earth is getting higher and higher.

And today, with the chaotic Nie Yun's black technology increasingly eroding the daily life of the earth, the long cosmic distance and high temperature can no longer stop the earthlings from letting go of their thoughts, so they turned their eyes to the sun!

In fact, as early as 1960, Freeman Dyson proposed a theory called the so-called "Dyson sphere".

He believes that the energy contained in a planet like the Earth itself is very limited, far from enough to support the development of civilization on it to an advanced stage, and a star-planetary system, most of the energy comes from stars!

But the radiation of stars is actually wasted, and the planets of our solar system currently receive less than 1% of the total solar radiation energy.

Therefore, a highly developed civilization must have the ability to surround the sun with a huge spherical structure, so that most of the sun's radiant energy is intercepted, and only in this way can it support this civilization for a long time and make it develop to a sufficient height.

Civilization has developed into the interstellar age, and it will inevitably enter full electrification, and the demand for energy will reach a very alarming level, so ensuring energy supply and improving energy collection efficiency are major problems that every civilization that goes into space must face.

Nie Yun, who has entered the interstellar era, will inevitably turn his attention to the use of solar energy.

The "Prometheus" project is the first galaxy-level project of human civilization that was publicly tendered by Captain Ghost, proposed by Lawrence, a top scholar, and certified by the Ghost Cloud Scientific Research Institution, and supported by the Earth Defense Force!

Prometheus is a god in Greek mythology who steals fire for humans, and Prometheus plans to steal it...... It's the sun's endless source of energy!

Speaking of this plan, there are "historical reasons" for its proposal and implementation......

Originally, Nie Yun's time in space was too short, even if he used mechanical insects to frantically mine and build a colony base, he didn't occupy much territory at all, and for the solar system, it was not even a drop in the ocean.

In terms of the current scale of solar system development, energy has not yet become a factor restricting the development of earth civilization.

Among the cosmic colonization bases on major planets and asteroids, Nie Yun has built controllable nuclear fusion energy centers of varying sizes, and the abundant nuclear fuel in the universe is enough to provide the energy needs of the bases.

However, with the large-scale entry of earthlings into the universe, hundreds of millions of robot troops have been put into use, various infrastructure projects have gradually been rolled out, and energy demand is increasing exponentially!

Among them, the major energy consumers include various mining heavy industry equipment, smelting centers, shipyards, quantum computer centers, and robotic insects......

According to statistics, the size of the current army of small robots in the solar system has reached about 350 million, and about 1 billion humans are taking turns to use these stand-ins to enter the universe through virtual helmets to engage in various industrial and entertainment activities.

Even if the energy consumption of each robot is not high, such a large number and 24-hour non-stop operation still need to consume a large amount of energy to recharge every day.

The smelting center is an energy black hole, and all industrial construction and infrastructure, including the daily rations of the mechanical bugs, are inseparable from metal, and the largest building in each colony base is the smelting center.

Countless minerals are collected and put into high-temperature smelting in smelting centers, and the large quantities of steel and parts produced are transferred to various production lines to make robots and industrial equipment, which requires a lot of energy.

The emerging space shipbuilding industry consumes a huge amount of metal. The importance of the shipbuilding industry to the interstellar age is definitely far greater than that of the Age of Discovery!

For the sake of stability in the rear, Nie Yun has not released the construction permit of the battleship for the time being, and the battleship shipyard currently only has an exclusive shipbuilding base for the Earth Defense Force located in the asteroid belt.

Most of the ordinary warships produced here are delivered to the Earth Defense Force.

As for the super battleship of the mechanical bug material...... Well, then shipyards are not needed at all.

The current solar system can be said to be loose on the outside and tight on the inside, and it seems that it has no military power, but in fact, it is a mechanical insect that can pretend to be a pig and eat a tiger.

When needed, Nie Yun could let the mechanical insects in the rear pull out a super fleet of fully mechanical insects in just a few hours.

In this respect, liquid metal warships that can change in all shapes can be said to have the innate stealth skill of "stealth".

At present, most of the mechanical insects are secretly devouring and breeding in the secret area that is not open to the public, and the number of mechanical insects is equal to Nie Yun's strength, as long as they don't stop eating food, Nie Yun's strength will expand steadily......

If it weren't for worrying about the safety of the wormhole's defense line, just in case, Nie Yun wouldn't even want to be stationed there with the Seawolf, after all, the resources near the wormhole were not abundant.

However, the two warships stationed in the wormhole were not idle, and there was a lot of metal mined in the fortress and the nearby celestial body, in addition to being used for the construction of war weapons, every once in a while, some steel would be transported to the two warships for them to devour.

If the Gemini's radar is accurate enough, it will be found that these two warships are slowly "fattening......

Compared to the cheating mechanical bug battleship, the construction of ordinary battleships is much more serious.

The shipbuilding base in the asteroid belt has been continuously expanded, and it is being sold at a rate of one ship per month, and the speed of shipbuilding is constantly increasing.

In addition to the first "Soyuz", another battleship has also been completed, and at the moment it is transporting a batch of supplies to the wormhole to join the defensive front.

Nie Yun of the military shipbuilding industry temporarily does not allow countries and forces on the earth to get involved, but in order to stimulate market competition and promote the development of the industry, Nie Yun took the initiative to open the construction application of civilian shipyards.

There are some powerful countries or forces, which one doesn't want to be strong and strong, crisscrossing the stars and the sea?

Even if only civilian ships can be built, it is a kind of technology accumulation, not to mention that you can also get a certain amount of technical support from Captain Ghost, this kind of good thing naturally no one wants to let go.

However, space shipyards are heavy assets, high-precision, and cannot be played without a certain amount of scientific and technological strength and economic strength, so at present, only the four major forces of Europa, Mi Guo, Mao Bear and Flower Planter have their own independent shipyards, and they can only produce small spaceships below 10,000 tons after completion.

Many conglomerates and Fortune 500 companies have also applied for the construction of more than a dozen small shipyards to produce 1,000-ton small spaceships through shareholding or joint fund-raising.

In order to meet the market demand, Atlantis has also set up a special banking institution to provide special low-interest loans, which has further accelerated the development of the shipbuilding industry.

As the scope of the solar system continues to expand, the issue of resource complementarity between various colonial bases is also on the agenda, and the hidden demand market for transportation ships is huge to the point of coveting, with massive orders, and tonnage ranging from thousands of tons to tens of thousands of tons per ship, no amount of production capacity can fill the black hole of rapidly increasing demand.

With the current production capacity, orders from governments alone are scheduled until 2025, not counting civil society organizations that can't even get orders.

And with that, the demand for materials has skyrocketed.

According to the codename, they will need to expand the number of current smelting centers by at least 2 times to meet the market demand, and the supporting energy centers will have to keep up, and the consequent fuel demand will also rise!

In addition to these infrastructure projects, with the popularization of virtual technology, billions of humans have poured into virtual communities, countless streams of consciousness require massive computing resources to process, virtual laboratories also need to consume a lot of computing resources, plus countless automated production lines and equipment, and the computing power occupancy rate of the code name continues to climb to new highs.

The Quantum Computer Center on the Moon has expanded and now occupies an area almost the size of five football fields.

Such a large quantum computer center consumes a lot of energy every moment, and fortunately, the moon has abundant nuclear fuel resources.

Of course, the above-mentioned series of resource consumption was also expected by Nie Yun and Codename, and with the current energy harvesting efficiency, it was enough to meet all the needs, and there was a surplus of about 10% to 20%.

However, life is always full of surprises, and Nie Yun still ignores the amazing spending power of certain groups......

Scientific and technological research and development has always required a lot of social resources, including energy, but what Nie Yun didn't expect was that the energy consumption of these scientists began to climb until it broke through the sky......

For a long time, Nie Yun, who insists on rejuvenating the country through science and technology, has carried out policy tilts and capital subsidies for scientific research, so the cost of electricity is basically zero.

I have to say that this initiative has stimulated the research and development enthusiasm of Yu Lao and his gang and accelerated the scientific and technological development of the earth's civilization.

But it turns out that scientists are the closest group of people to madmen, and mad scientists without limits are even more of an old gangster!

Nie Yun's connivance made Yu Lao and other scientists use energy without scruples, just last month this guy organized a "research on energy plasma", the energy consumed accounted for 3% of the total energy consumption of the month!

That's almost a month's worth of electricity for a colonial base!

However, these guys don't know the price of firewood and rice, and some time ago they actually applied for a series of "super" experiments that start with "super", such as super-large quantum collision, ultra-high temperature plasma, ultra-long-range fortress-level laser cannon, super-heavy gravitational collapse, etc., which are very tall and high-level "super" experiments at first hearing.

Make one today, get two tomorrow, and look at the future plan It seems that it is still an equal difference series of increments, I'm afraid that if it weren't for the lack of manpower, these guys would turn all the celestial bodies in the solar system into laboratories......

Then the code name of the big housekeeper found that his energy increase rate was almost unable to catch up with the energy consumption rate......

Not long ago, Nie Yun, who was working the front line, was stunned when he received the system prompt of "energy is insufficient, please recharge as soon as possible" from the rear!

Lao Tzu has nuclear fusion! You actually told me that Lao Tzu was in arrears?!

Could it be that the front line has not yet started a war, and I have to start using the strategic resource of energy crystals?
