Taking advantage of the time, Cao Chuan's rules simulated a protective force field. The biggest difference between it and the deflection magnetic field is that the deflection magnetic field has a very small surface, and the defense effect is only slightly reduced, but it cannot completely eliminate the damage.

The most basic requirement of the protective force field is to be able to construct the shape at will, support enough area, and have a way to resist the impact of kinetic energy from the outside world.

So, this simple description involves several technical issues.

First, how to construct the shape freely, at least the energy of traditional light cannot be used as a film to wrap the spaceship.

Second, how to effectively resist external damage, assuming that it is a kinetic weapon, a cannonball must at least penetrate the thickness of the atmosphere and the density of the block, the power will be effectively reduced, so the thickness of the force field will not be low, and it must be guaranteed that it will not affect the interior of the spacecraft.

There are many similar questions, leading scientists to dream of using energy as a means of protection for spacecraft, energy is more expendable than matter, but in fact, the protective force field has always been a barrier that the scientific community has not yet broken through.

"Let me think, how do you order a tech tree? I always feel that something is wrong..."The rule simulation showed vague results, and slowly, Cao Chuan found the first technical requirement for the protective force field, that is, the wireless power transmission technology that was born for some years.

"Using mature wireless power transmission technology, it is possible to create a stable, outgoing spherical force field. As long as we find a way to increase the power of the wireless transmission tower, we can make its function change from transmitting energy to dissipating energy, which plays a role in protecting us. ”

"The biggest disadvantage of wireless transmission technology is the energy loss, because the protective force field always works in a vacuum and does not lose time due to passing through the air, and the way to keep the wireless transmission tower in a closed field. The energy cycle continues, and the energy consumed will be reduced by at least 95%. ”

"Reinforcement force fields with a thickness of more than 50 meters, such as electromagnetic cannon shells, meteorites, and atmospheres, will be hindered by the energy field and cause a reduction in kinetic energy. Reducing the quality solves the second problem and achieves an adequate degree of protection. ”

The protective force field cannot protect the energy, and the work of protecting the energy is still handed over to the energy absorption armor plate to be effective, and the technology is more mature.

Otherwise, it is necessary to protect both the material and the energy, and at least there is no energy that will have a countervailing effect on the other, except for the extremely expensive counter-energy. Obviously, this thing can only be used by scientists for experiments at most, and it is definitely not extravagant enough to be used in the military field.

Three loli whispered to a blueprint of a protective force field tower.

"Do you want to deploy multiple protective field towers on the ship to create a spherical field?"

"Yes, otherwise working through a protective force field tower will not only waste energy, but will also affect the crew and the interior of the ship."

"In terms of energy savings, can it be solved by the Shen excitation effect? In normal times, the defense field will operate at a lower power. When an external material cutting force field is sensed, the force field tower will be within 0.1 seconds. The power skyrockets by 10 times, thus strengthening the blocking effect and stopping the dangerous big guys. ”

"That's true... After repeated calculations, even if the protective force field tower is allowed to work in a vacuum environment and maintain a closed field state, the energy consumed is still a bit terrifying. More energy-saving means had to be introduced. ”

…

Lori asked questions one by one, in their opinion, there are many problems in the protective force field, even if these problems are not actually problems, they can be solved by existing technology. If they can't figure it out, they can't make it.

Lori got to work, and Cao Chuan then considered a mature energy extraction device that would be enough to meet the needs of 100 years later.

However, this time, after the rule simulation, he found that the original star flow supply technology is still not valid, which can be regarded as a wrong path, even if they develop hydrogen and helium fusion energy technology, they will get more from the universe, and at the same time, more advanced spacecraft will only produce higher energy consumption.

As a result, the thin stardust could never effectively alleviate the contradiction, and as the rules simulation progressed, he still set his sights on stars and gaseous planets.

The main constituent material of these two stars is hydrogen helium, the difference is that the environment of the stars is slightly harsh, the temperature of 1000 degrees Celsius on the surface makes it impossible for them to get close easily, only they are enough to satisfy the appetite of future spacecraft, and as the speed of the spacecraft increases, the time cost of resupplying different stars will be greatly reduced.

"Suppose there is a device that allows our spacecraft to get close to the star, easily dig out a large lump of hydrogen helium, and then transport it into the spacecraft, then the problem is solved." The results of the rule simulation are displayed as follows.

A more vivid picture appeared, a spacecraft with depleted energy swept through the depths of Jupiter's atmosphere at a lower speed of 1000 km/s, and then the spacecraft released a smaller moon-by-month spacecraft, a shell composed of molecular materials that withstand high temperatures and pressures, even if it is close to the sun, Centaur Alpha B will not have a big problem, and even if it is touched by cosmic disasters such as solar and flares, it will not have an accident.

The interior of the ship was empty, and as it came into contact with the ubiquitous energy outside, the ship opened its mouth like a whale swallowing, and the hot hydrogen helium was compressed and loaded, rapidly cooling into a liquid or even solid state, reaching 200 tons until it was full. The fully loaded Moon-Class ship then returns to the mothership, which is farther away from the stars and almost risky in the process of resupply.

When the high-pressure hydrogen and helium material in the moon-to-month spacecraft is dumped out, these high-quality energy sources are easy to use, according to the current generation of technology, 0.02% of the deuterium-tritium, helium-3, even a few tons are enough to meet the spacecraft's long-term needs; When hydrogen and helium fusion energy is born, these energy sources can even be used 100% cleanly, and there is no need to worry about mining and using them.

"Do you want to do something to the Moon-By-Month ship?" Cao Chuan said to himself that the production of energy extraction equipment does not involve bottleneck technology, but because it will definitely take some time to transform the spacecraft.

Fortunately, there is no shortage of time for the time being, and it took him another 2 years to transform a moon-by-month spaceship on the Galaxy Echo into an energy extraction spacecraft, and in this way, the technical level of the Galaxy Echo once again opened up a large section of existing human technology.

At present, the protective force field and energy extraction equipment only exist in the Galaxy Echo, in fact, the two are suitable for popularization and wide range of applications, not only for spaceships, but also for space stations floating in the universe, and ground buildings.

Imagine that putting a protective force field directly outside the military base will greatly reduce the power of the kinetic weapon, making it an unstoppable fortress.

Building a large-scale energy extraction station in the orbital space of the star, resisting thousands of degrees Celsius of high temperatures and strong electromagnetic fields, while continuously extracting energy for fusion, is the real feasible way to achieve a Dyson sphere. (To be continued.) )
