Chapter 1509 Invention
There are many records about Princess Wencheng in history, but almost no one knows about Princess Wencheng's origin, and there is no detailed statement so far. It is even possible that Princess Wencheng is not the daughter of the collateral lineage of the Li family. It is possible for the maid to adopt a goddaughter.
These all illustrate one point, don't think about contracts and the like, it's useless, big fists are the truth.
All contracts are forced choices made by both parties when they cannot physically convince each other.
This is the current situation of human beings. There are more than 200 countries on one planet, and these countries conquer each other. However, if one day, an alien civilization suddenly appears in front of the earth, and if human beings do not unite, they will all be destroyed. wipe out.
At this time, all racial conflicts and belief conflicts must be put at the end. I dare not say that the earth can be quickly unified into a country or a federation, but at the very least, a united front will be formed in a very short period of time. Absolutely no problem.
If the two sides continue to confront each other and fight for a long enough time, then it will be a matter of course for the earth to become a federal country.
Without pressure, everything is in vain, unless the technological level of one of the countries can suddenly be raised to the point where it can kill all other countries in seconds.
Even so, to be honest, let the country choose at present, the country will not choose to engage in unification, or alliances.
Isn't it good to develop the world of Daqin and Song? Going further, isn’t it good to develop the moon and Mars?
When other countries lag behind to a certain extent, they will carry out cultural infiltration step by step, and when the culture of the other country is finally eliminated, it will be difficult for the other country to integrate.
Sometimes, that's the case with each other.
The lifespan of human beings is too short. With a history of more than a hundred years, if there are enough wise leaders to formulate some long-term plans, it only takes two or three generations to wipe out the other party's culture.
Aren't there many examples in China? There are too many of those useless youths who kneel down and never get up again. The contract is only 99 years, but in fact it is only 156 years.
Therefore, Jiang Yanhai's design at the moment is more about how to return between space and the ground, as well as the design of the spaceship in space.
These designs can be said to be unprecedented, and there are no examples to consult, because these designs are related to more than just a spacecraft. A spaceship must have a complete environmental adaptation system, and human beings consume resources every day.
It's not just a matter of designing a spaceship and providing enough power can be solved.
If the internal circulation system of the spacecraft itself cannot be solved, or if it is not solved, at least it is like a water source, air, etc. can at least solve more than 50% of them through internal circulation, then it will have the possibility of real long-term recycling and mutual development between planets sex.
The second is the construction of bases on each planet, etc., all of which need to be considered.
Energy has only solved the most basic, and there are still many, many remaining problems.
But at least, China has come to this point, hasn't it?
We are no longer just a matter of detection, we are ready to actually take this step.
Waiting for the appearance of this mechanical octopus, Jiang Yanhai is constantly simulating and manufacturing these space planes between the ground and space in the illusion simulation program.
If there is enough power, it is indeed unnecessary to reach the first cosmic speed in a short period of time like a rocket to get rid of gravity.
After entering space, the air there is thin. At this time, if enough thrust is provided, it will be easier to accelerate to above the first cosmic speed.
But how to choose between the two is difficult.
Because you continue to give the aircraft a fixed thrust, even if it is as fast as a human walking, it can still leave the earth. But the energy of such continuously consumed fuel is undoubtedly very large.
It is impossible for the rocket to carry so much fuel, so the rocket must use the fastest speed to increase the flight speed, but the weight of the transported object must be considered, so there must be a qualified trade-off in the middle.
In fact, if there is controllable nuclear fusion, this will be different, just like the mainstream ion thrusters in the world are all electromagnetic, which is a concept similar to the electromagnetic rail gun, which accelerates plasma to a certain level through a magnetic field. The super-high speed, and then ejected from the nozzle, so as to bring thrust.
But because all the current satellites and spacecraft can provide limited power, the power consumed to provide magnetic field to generate thrust is naturally very limited.
At present, it is only useful in space, and it is basically used for steering in space. Only some probes released outside the solar system will use such things to operate the main thrust, because there is a long enough Time allows it to continue to run, and at the end, its speed can also reach an extremely high speed.
However, there is another kind of ion thruster, which is the arc heating type. It actually places a point between the two electrodes to form a high-temperature arc to heat the gas. After the gas enters the compression section of the anode nozzle, it is heated by the arc to a high temperature above 10,000K, that is, Ionization occurs at high temperatures above 5000 degrees Celsius.
Then the gas enters the anode nozzle and expands shortly, the expansion accelerates to above the supersonic speed, and finally ejects at high speed to form thrust.
The arc-heated ion thruster has great development prospects. Although it is lower than the thrust/power ratio of the electromagnetic formula, it is not known how many times higher than the chemical formula.
In addition, its simple structure, low operating voltage and long life are all advantages.
When the question is mentioned here, everyone should understand one thing, that is, after controllable nuclear fusion, what is this arc-heated ion thruster? This thing also needs electric discharge heating, but don't forget about the controllable nuclear fusion, it itself has extremely terrifying high temperature! Just tell me how many degrees Celsius you want!
Its core temperature can reach 100 million degrees Celsius! If the temperature of the controllable nuclear fusion can be used to generate electricity through the fusion reaction, its temperature can also heat the air and accelerate the ion acceleration. This thing is simply the best of both worlds.
Otherwise, why is controllable nuclear fusion the most important invention of mankind.
Now, what Jiang Yanhai is working on is how to reasonably miniaturize controllable nuclear fusion.
If you turn it into a robot-sized core that can function from it like in a sci-fi movie, humans can't currently do it.
But if it is enlarged to a certain volume, such as the huge volume of An 225, to be honest, it can actually be done.
