Chapter 48: Shortcomings

Chen Yue still took as much redundancy as possible during the construction process of this supercomputer, which is about to become his "new home", and used all means to improve safety.

It took a full year to build. It took another year to verify the security. Two years later, Chen Yue finally relented about its reliability.

After moving to this new supercomputer, Chen Yue felt the surging computing power, and Chen Yue's heart was even more excited.

Compared with the old supercomputer, the computing power of this new supercomputer has increased by as much as 7 times.

At this time, Chen Yue really felt that the nuclear fission ion propulsion spacecraft was a little insufficient for him.

At this moment, the development of more than a dozen planets in the entire Jupiter system is only less than 10% of the computing power consumption for Chen Yue. Counting those research bases, the top computing power can occupy 20%.

What is the rest of the computing power used for?

Nowhere is it available.

Building more industrial infrastructure?

No way. Because almost every exploitable planet has already been developed.

Build more research bases?

No way. Because the combined resource supply power of more than a dozen moons of the Jupiter system can only support these current research bases. If there is more, there will be no supply of resources and energy.

Research Science? Advancing science?

No way. If there is not enough research base to produce scientific data, what can you do to promote scientific development? Out of thin air? That's not going to work.

After Chen Yue checked his current development level of each category, he quickly locked down his biggest shortcoming.

Space transport capabilities.

After the increase in computing power, you can certainly control more spaceships, but the transportation needs of the entire Jupiter system are limited. At the moment, there is simply no need for so many ships.

But...... For the transportation capacity of planets other than Jupiter, it is still far from enough.

Not even a ship several times as large as it could be built.

At present, in addition to the planets in the Jupiter system, the closest planet with great potential for development is Mars.

Mars is a real big planet, and its size is not comparable to the moons of Europa, 2, 34.

It will be able to supply itself with more resources and energy, and open up a bigger world for itself.

But it's too far away.

At its closest to Jupiter, it was nearly 500 million kilometers away. The farthest is about 900 million kilometers.

With such a long distance, the nuclear fission power ion propulsion spacecraft that he can build so far can of course be reached. But large-scale transportation, that's far from it.

Moving from the Jupiter system to Mars is also not feasible.

Of course, it is possible to move, but the abundant variety of resources in the Jupiter system, as well as the industrial base accumulated over the years, are also indispensable to Chen Yue.

Jupiter's system and Mars, Chen Yue wants. Indispensable. Then you have to find a way to connect the two. What is the bond that binds you together?

Naturally, it's the ability to transport in space.

"The key to improving the ability to transport space is to improve the performance of the spacecraft. The key to improving the performance of the spacecraft lies in two aspects.

First, improve energy density, and second, improve energy utilization.

I am afraid that the energy utilization rate will not be possible in the short term. I'm almost at the limit of my current ion propulsion technology...... If the basic theory is not broken, it may be impossible to improve it.

The only way to start is with energy density. Hey, nuclear fission really doesn't work, you still have to go to nuclear fusion. After a big circle, I finally got back to square one. ”

Chen Yue is trying to circumvent the limitations of controlled nuclear fusion and use current technology to achieve the goal of linking the Jupiter system with Mars. But he eventually found out that it was impossible.

The essence of ion propulsion technology is still to drive the spacecraft through reverse thrust. However, the velocity of the jet jet is very high, which results in better performance than traditional chemical propulsion technology and more economical working fluid.

At present, the ion thruster built by Chen Yue can reach a maximum jet speed of 200 kilometers per second.

Obviously, the higher the jet velocity, the greater the thrust per unit weight of the working fluid can provide.

But it's not easy to increase that speed. This involves an overall improvement in the extremely sophisticated ion acceleration technology.

At the current state of the art, 200 kilometers per second is the most economical. Since then, the speed has increased to 220 kilometers per second, an increase of only 10%, but the energy consumption has increased by about 50%.

Doubling to 400 km/s increases energy consumption sixfold.

With Chen Yue's current ion propulsion technology, it is impossible to reduce this energy consumption for the time being.

But there is a limit to the amount of energy that can be supplied by a nuclear fission reactor. If too much energy is wasted, the total acceleration capacity is greatly reduced. Nuclear fuel, which could have lasted a year, may run out in a month.

Nuclear fission must use heavy elements such as uranium or plutonium, which are scarce in content and troublesome to enrich, and Chen Yue cannot afford them.

As a result, there is a ceiling on space transportation capacity, which cannot be improved.

If the energy consumption cannot be reduced temporarily, the only way to obtain a higher jet speed is to increase the total energy supply.

The total energy supply is too large, even if it is not in the state of economic operation, it does not matter if it is wasted a little more.

"Controlled fusion research is necessary. Only controlled nuclear fusion can significantly increase the total energy supply. Moreover, nuclear fission fuel is scarce, and nuclear fusion fuel is abundant, and it is easy to obtain. ”

Chen Yue made up his mind.

and...... In a space war, a nuclear fusion spacecraft is qualified, and a nuclear fission spacecraft is not a good game at all. Only with nuclear fusion technology can I truly have the power to protect myself! ”

Chen Yue has never forgotten the war twenty light-years away.

Twenty light-years is a long way off. But compared to the enormous scale of the entire universe, twenty light-years is as close as the front yard and the back yard. I don't know when the war there will spread to my side.

"Nuclear fusion releases an average of about six times more energy than nuclear fission. In addition, after mastering nuclear fusion technology, with my energy conversion technology, it is possible to achieve lower losses than nuclear fission. Overall, a fusion reactor can increase the total energy supply by up to 10 times compared to a nuclear fission reactor! ”

With a tenfold increase, it will not be difficult to complete the connection between the Jupiter system and Mars.

What's more, the huge potential of nuclear fusion technology at the level of space warfare also made Chen Yue have to give it the highest attention.

A variety of factors are superimposed, even if Chen Yue feels that his technical reserves and scientific reserves are still a little short at this moment, he has to be forced to get on the horse.
