Tower Defense Strategy - Chapter 277

“Tower Defense Strategy (!

The successful delivery test of the dry-air engine means that human spaceflight has entered a new era.

Its practical application is no less significant than an electromagnetic orbital launcher.

Secretly speaking, Han Yan is also the first engine to use black magic superconducting material.

As mentioned earlier, the Black Magic Guide is a high-temperature range superconductor. It can only be transformed into a superconductor in the high-temperature zone within one or two hundred degrees. The situation is counter-intuitive to the earthball people, and they don’t know where to use it, so it has always been just Small-scale production and supply laboratory in the same way that superconductors were produced a few years ago.

And when studying the data of the zero-gravity processing system, everyone realized what the Black Magic was doing.

Simply put, it can export the electrical energy converted by a professional high-temperature generator in a specified temperature range.

…A copper wire seems to make no difference.

The difference is not in the conductor, but in the power generation mode of the heat recovery device.

Generally, the heat recovery device generates electricity by means of closed boiled water, but there is also an emergency structure.

When the temperature reaches a dangerous level, it will trigger a pressure generator, which provides a force to the pressure plate power generation mechanism through directional thermal expansion and contraction.

Once the pressure generator is started, the metal fatigue phenomenon of the structural parts is very serious. It is almost a one-time crisis management structure. The advantage is that the limit power generation is very huge. The more thermal energy waiting to be processed, the higher the temperature, the greater its power generation. If the damage caused by temperature is not considered, its energy can even start a nuclear bomb easily.

In fact, some of the nuclear bombs used in Death Scepter No. 2 have been used to replace explosive shells with the structured miniaturized device, which has contributed to the further miniaturization of nuclear bombs. Unfortunately, because of the harsh high temperature environment, it cannot be used on ordinary missiles.

In a high-temperature environment, the resistance of general conductors will increase instead, and a large amount of electric energy cannot be effectively exported. Only by exporting with superconductors can the temperature of the emergency system be effectively and quickly controlled.

Inspired by this emergency structure, some laboratories naturally carried out special research and successfully applied it to Drought-B.

However, it is also for emergency use on droughts, and the conventional power generation uses a Stirling generator (external heating).

In addition to the vector electric propulsion that assists in the direction change, the power generation mechanism of Hanyan also has a set of special energy waste devices.

In fact, the converted electrical energy is sprayed out in the form of electromagnetic waves in large quantities. The principle is a bit like a weapon radar, except that the structure is simpler and the power level is even larger.

It is through a variety of energy conversion and consumption structures that the drought can control the waste heat generated by the extreme working environment with a temperature of more than two thousand degrees.

Looking at the test results, the shell temperature after work will still reach 600 to 900 degrees, but it is definitely the one with the largest proportion of waste heat treatment in the high specific impulse nuclear power engine. Otherwise, it will not be able to make a round trip. The degree of improvement is enough to become the cornerstone of manned spacecraft between planets.

Speaking of waste heat again, I have to mention that it is the biggest enemy that mankind has faced since the first exploration of space.

Satellites have to deal with the waste heat caused by the heating of sunlight, and spacecraft have to deal with the waste heat leaked by the engine more carefully. For this reason, mankind has developed a lot of space heat treatment methods.

However, in the past, limited by the cost of space launches, the main direction of everyone was to use the least weight to dissipate the heat in the form of thermal radiation.

Now with the experience brought about by the frequent use of electromagnetic orbital launchers, the bottleneck of launch weight is no longer so uncomfortable. The relevant agencies of country C have gradually focused on the reuse of waste heat.

In outer space, zero degrees is not called low temperature, but zero K (absolute zero degrees) is.

The structure of boiling water for power generation can use heat energy above 373K, but in actual operation it can only use above 380K.

So is it possible to recover the heat above 14K by boiling the liquid hydrogen to drive the generator?

The temperature difference of 286K, the energy contained in it is very attractive, but the span is too large, and the equipment and materials that can work normally at that temperature and maintain the strength are lacking. It is necessary to go back and choose a target with a higher boiling point.

There are three candidate substances, ranked according to the degree of dependence on space resources, namely carbon dioxide, chlorine, and radon, with boiling points of about 195K, 239K, and 211K, respectively.

Carbon dioxide generally only transforms between solid and gaseous states, and will become liquid under high pressure. On the contrary, it is the most difficult to simulate the action of “boiling water to generate electricity”.

Radon is a radioactive gas. Leakage is too dangerous and it is more likely to cause equipment damage.

Chlorine is more friendly in terms of temperature, but similar to radon, it is also a high-risk gas. At the same time, it is also an active corrosive gas, which is not a small harm to materials.

Maybe some students want to ask, why are you so keen on boiling water?

Because humans can only boil water.

Think about it carefully, in addition to boiling water, what other means have humans mastered to convert heat into electricity?

Stirling generator? The same is the process of heat, kinetic energy, and electricity, and there is no essential difference between boiling water. Even if it is an emergency thermal power generation device in a zero-gravity factory, thermal expansion is still used to generate electricity.

Therefore, the essence of science is to boil water, which is not without reason. Of course, now that humans can use light energy to directly convert electricity into electricity, it is not the only way to generate electricity with kinetic energy similar to boiling water.

The form of kinetic energy power generation wastes a lot of energy, but the heat insulation ability of vacuum can solve many problems. Blocking the heat radiation with reflective materials can effectively improve the heat conversion efficiency. Today, when the emission weight limit is reduced, there is no reason not to continue. develop.

Now people have studied the three kinds of gases, and they are also looking for other more controllable, safer, and can be used frequently in space based on gases and liquids, looking for new methods to boil water.

In the book collection of the Deep Space University of Technology in the game, there are actually models that do not use kinetic energy to generate electricity. Unfortunately, I don’t understand.

Not being able to understand is not completely incomprehensible.

The method recorded in the collection is very simple, it is a kind of stuff similar to photosensitive ceramics, photosensitive ceramics are used as photovoltaic panels, and thermal ceramics can naturally be used as thermal radiation generating panels.

What the Tuqiu people don’t understand is how to make the thermal efficiency of this kind of things exceed the kinetic energy power generation system.

Thermal kinetic energy boiling water power generation system, including coal, oil, gas, etc., the conversion rate of thermal energy and kinetic energy is up to over 50%, and the final power generation efficiency of coal-fired power generation is between 30% and 40%. Fuel and gas are several percentage points higher. The vacuum environment adopts various designs to relax the cost and reduce environmental losses. Water, turbines, and steam function in a closed environment, and the heat utilization rate can be higher.

The conversion rate of photoelectric, which is the highest light energy conversion ratio that modern humans have, has not reached 40%.

How many years have photovoltaics developed?

It can be said that unless someone suddenly finds a “only” correct answer that may exist, even if humans produce something like thermoelectric conversion ceramics, how can they develop beyond boiling water technology?

Unlike photovoltaics, there is no type advantage in direct thermal power conversion. Since it is a conversion from heat to electricity, as long as the utilization rate of boiled water is not reached, no matter how boasted, there will not be many people to promote technological development.

I’m afraid it’s not necessary in the atmosphere. Let’s talk about regulating temperature. Photovoltaic coverage and geothermal energy do the same thing. After all, the energy in the atmosphere comes from sunlight. change.

Boiling water technology has a large scale of application, low cost, and high technology maturity and reliability. With the improvement of environmental standards, the pollution rate has also dropped, and wind and water power are also included (both are kinetic energy power generation, and the natural transportation of wind and water is actually thermodynamics. As a result), there is no one that can escape except direct photovoltaic. It is difficult for Tuqiu people to imagine how a class of materials will emerge, and the power generation efficiency can be developed to compete with boiling water technology under the premise that there is no living soil at all.

Tuqiu professionals are not stubborn~www.mtlnovel.com~ Guess the two situations that can promote the development of thermoelectric direct conversion technology.

The first is the advantages in weight and reliability.

Although boiled water has been developed on a scale for more than two hundred years, the reliability is high enough, but what kind of situation will be encountered in the universe, human cognition is still relatively limited, so if the thermoelectricity is directly turned to the same power, there is a certain weight advantage. And more reliable, there is a basis for development.

In the second case, the technology was not developed by aliens at all, but was developed by AI!

This guess is only circulated within the scientific research system of Country C, because here, more and more people have heard that the mecha design in “Planet Strategy” is made by AI.
