In this eventful summer, for the sake of human security, the Security Council finally issued the highest level of plague warning through the World Health Organization, and most countries are beginning to strategically stockpile anti-biological and chemical equipment.

A secret district in the Soviet Union near Yekaterinburg was marked as a "high-risk zone" by Google Maps. Countries with decent intelligence sources know that this is a secret Soviet laboratory dedicated to the development of biological and chemical weapons.

NATO reporters speculated that it was the Soviets themselves, and some daring reporters even got pictures of the green plague, which scared many cowards to death.

Customs in various countries basically suspended all flights, trains, and cargo ships from the Soviet Union, which was more effective than economic sanctions.

The Soviets, who were already short of protective equipment, were even worse at this time, and they were especially angry that the Americans and their allies seemed to be deliberately stirring up trouble at this time, not allowing their own country's companies to send protective equipment to the Soviet Union when the epidemic broke out.

Japanese journalists interviewed on the streets of Tokyo: "Hello! Do you think this mysterious virus outbreak will lead to the end of the world and the siege of zombies? ”

Citizen: "It's really possible, it's said that the green herpes of dead people will float in the air like pollen, it's terrifying, it's even more terrifying than the Umbrella Corporation's T-virus in Resident Evil." Hey, pollen frustration! People with pollen allergies are in pain to death when the flowering season arrives, and they must wear masks when they go out. ”

Citizen 2: "Possibly! The intensity of the infection will silence people, and some patients will have strong violent tendencies, which is really terrible, don't let the Soviets enter the country! ”

Suddenly, real estate in undersea cities is booming, because humans have a vague sense that the end of the world is really possible.

The Soviets felt particularly wronged, we didn't bring it to Siberia in the first place, it's abominable! There is a guy who gave the KGB boss a bad idea, let Alaska in the United States also infect it, don't let us be a country to bear the blame.

The Soviets really did it, sending a transport plane to drop an infected body to Alaska. Not long after, the outbreak broke out in Alaska.

The world immediately grounded all Alaska flights, and panic began to spread further.

A World Health Organization official said: "Please don't panic, we have made preliminary discoveries that the virus is relatively fragile in the face of large water bodies such as oceans and rivers, and it is impossible to cross too many obstacles, and the destructive power is limited." ”

In order to stop the spread of the epidemic, Li Xiantai made a robot on duty in the epidemic area in the name of the Magic Dragon Company, and implanted the "cube-shaped brain" of the Innocent Warrior into the robot's head after protective design, with stainless steel as the skeleton and carbon fiber as the skin, and the "zombies" could be subdued with non-lethal high-voltage electricity.

Magic Dragon sells such robots to health departments in various countries for $100,000 a piece. Japan's Ministry of Health and Welfare, after testing, took the lead in promoting its use to cities in its own country, purchasing 100 sets at a time as a preventive measure.

Yuki Saki was shocked at this time, the magic dragon technology actually had such an earth-shattering technology, and it became a sweet tooth when the "end is coming".

Isn't Nazu Ru-chan a teenager?

He had no choice but to push off with "I'm just the nominal boss and don't know anything".

Humans are quite cautious about the use of robots, but at the moment when the virus is raging, no one cares about this. Even the Yankees, who are most opposed to robots, have ordered 1,000 robots on duty in epidemic areas in one go.

The "Japanese" are well known for their attainment in robotics. These electric shock robots can be as intelligent as human police, and the shock masses pretended to be by the American police in the test were all intercepted without exception, and a small number of robots that successfully broke through the level will immediately notify the command center, and then will be "killed" by the helicopter police in the exercise with machine guns.

They also mimic human breathing, analyzing the composition of the inhaled gases to determine within a minute whether the air has been contaminated with a virus.

Not even the U.S. Centers for Disease Control and Prevention (CDC) has invented such an artifact, and they urgently need a device that can detect it to determine the borders of Alaska's infection.

The CDC's painted helicopter lowered these senseless warriors into high-risk areas one by one, and then hurriedly pulled them up.

“clear！ Next testing site, one kilometer ahead. "One minute after being put down, the CDC robot reported to the command helicopter in English very humanely.

The chemicals that can be used for testing are limited, so they can only be tested at intervals.

The staff on the helicopter secretly congratulated themselves on having such an advanced machine, otherwise it would be quite terrifying to go down to carry out the mission.

The CDC has also boldly directed robots to collect virus samples for study, and they have discovered that the robots are so clever that they can fully understand their commands. In fact, the Americans are very suspicious that the intelligent modules of these robots are cyborgs, but at this time they can only turn a blind eye.

At this time, the human submarine city plan is a complete failure, because the underwater city of cyborgs has been inhabited by tens of thousands of people, and the housing prices have been speculated to be very high, just like a prosperous town, but the human submarine city is still hard to build.

There are 100 10,000-square-meter islands in the sea, and most city dwellers have to travel through Honiara in the Solomon Islands to get there.

Already observant air passengers have discovered that in Honiara, an otherwise backward and absolutely third-world city, a huge solar thermal power generation matrix has appeared. What's even more incredible is that this matrix is unexpectedly different, the central part is not a simple collector tower, but a huge platform, like a place to park an airplane.

Hey, are you going to build another helipad in the middle of the day? This is too lacking in heart, right?

A solar power expert examined the amazing infrastructure of this country where birds don't lay eggs, claiming that this power station uses nearly 200,000 mirrors, making it one of the largest solar collector power stations in the world, with an installed capacity of more than 400m, enough electricity for 800,000 people, however, the population of the entire country of the Solomon Islands is less than 600,000.

Of course, there is not only a civilian market, but now, the Solomon Islands has become a stronghold for cyborgs, and there are a large number of Chinese people who come here to work and live, and it is estimated that these surplus electricity will soon be used.

Lin Mao gave this solar heat-based rocket engine a terrific name: the Solomon National Ignition Device.

On this day, the first ignition test began.

A 100-meter-tall test tower is tied to a test heat engine, the conical bottom is blocked by transparent glass, and the air inside is heated and expanded by a large amount of solar heat that arrives instantaneously, and the expanded air pushes the piston at the other end to move in the cylinder.

The piston drives the flywheel in a reciprocating motion, cooling each time the cylinder expands, then retracting and heating again, and in the long run, the piston motion can be converted into a circular motion with a gearing, resulting in an unrivalled turbofan.

The original concept was to directly ignite the air, but Saberii had not invented a feasible solution for a long time, so Lin Mao, an amateur engineer, proposed this, it turned out that this thing was not new, it had a proper noun: Stirling engine.

It also greatly increases the usable height of the engine because of the use of a massive turbine. To improve the controllability of thrust, the turbofan was divided into four, like a simplest quadcopter drone.

It's just that its size is amazing, it can lift hundreds of tons of rockets, send them to an altitude of more than 30 kilometers, and then ignite the liquid hydrogen rocket from 30 kilometers of thin air, and the air resistance required to break through is quite small.

In the unlikely event that the four-axis turbofan gets out of control at high altitude, Lin Mao prepares a huge paraglider made of Zero material, which will pop out at a critical moment, allowing it to calmly return to the launch base.

The human brain has an endless imagination, and the happy amateur engineer needs nothing more than imagination, and all the technical details are done by saberii, which is a real blessing.

The huge thrust generated by the four turbo fans is exactly the same, in order to prevent the body from catastrophically tilting due to unfavorable factors such as strong wind, gravity, centrifugal force, turbulence, etc., the size of the air inlet can be adjusted, so as to indirectly adjust the thrust of the four turbofans.

From a small model to a meal, to 10 tons, 100 tons, from a low altitude of 100 meters to a detachment from the protection tower, 1000 meters, 10,000 meters.

After dropping a dozen prototypes (returning to the launch pad after entering the Zero paraglider catapult program), the powerful launch platform has matured day by day, and they have reached the stratosphere and are more confident in the control of the aircraft.

Start installing the simulated rocket!

Of course, it can't be set up on the platform like that, because the center of gravity of the four-axis turbofan is too high and is easy to be blown down by strong winds, so the center of gravity of the rocket must be located in the center of the entire platform, so as to create a smooth ascent to the middle of the atmosphere.

The Earth is elliptical, the equator is a bulge, and the atmosphere here is only 7 kilometers, while the polar regions can reach up to 17 kilometers thick.

Placing a rocket directly into the middle of the atmosphere at low cost is how attractive it is for astronautics.

Today, SpaceX is the cheapest rocket in the world to launch, only $2,000 per kilogram of cargo, in order to get the launch capacity faster, Lin Mao decided to cooperate with SpaceX, claiming that the launch cost of SpaceX can fall below $1,000 per kilogram.

As long as the "Solomon National Ignition Device" charges a service fee of $500/kg, the project will start to make money, and everyone will be happy.

SpaceX plans to launch 4,000 small low-orbit satellites of 100 kilograms as a global wireless Internet, and now their launch cost can reduce this astronomical launch cost to $400 million, which is really feasible.

Note: When they were planning, the cost was still in the tens of billions of dollars.
