Tower of Babel

In terms of energy, Zhang Cheng assisted in the construction of a large number of thorium-based lava reactor nuclear power plants. Thorium is a low-radioactive element and cannot rely on its own neutrons to carry out chain reactions. To ignite thorium, a neutron source is required to ignite it. Thorium absorbs neutrons and transforms into uranium 233. Although uranium 233 can sustain a chain reaction on its own, uranium 233 is more unstable than uranium 235. It is a process of production and combustion. It cannot be hoarded and used to produce nuclear weapons.

The nuclear waste produced by this kind of nuclear reactor is in solid form, and there is no risk of nuclear leakage. It belongs to the fourth generation nuclear reactor. Compared with large fusion reactors, it has a simple structure, low cost and small size. The production cycle is short. It can even be used on ships and aircraft. In addition to being used as a nuclear power plant, it is also a very good power reactor. But the feature of the nuclear power plant built by Zhang Cheng is not just that, but also its unique power generation system.

Skynet is a very serious and stubborn guy in scientific research. After being conquered by Zhang Cheng, he has been working on how to improve the efficiency of the power generation system. Skynet strongly disagrees with the human AC power supply system. In Skynet's view, there is no scientific basis for humans to choose a power generation and transmission frequency of 50 Hz. , is not the best frequency. Skynet has been studying what frequency has the highest power generation efficiency. Have been working on a high-efficiency generator. Skynet also does not agree with the DC power transmission and transformation system. In Skynet's view, it is not cost-effective to use an inverter to go back and forth between AC and DC. Because inverter frequency conversion also has power losses, and the skin effect of low-frequency alternating current is not obvious.

The higher the frequency of alternating current, the more similar its properties are to radio waves. The greater its own reactance, the less conducive it is to flowing in conductors, and the more it tends to propagate in insulators. Therefore, the power generation efficiency is by no means the faster the generator speed, the better. Because the higher the speed, the higher the frequency, the greater the reactance. There is a common phenomenon in generators, that is, when the load is increased, the speed decreases, but the output power will increase, which may burn out the electrical appliances. After the throttle speed is increased, the power will decrease to the normal range. Because the higher the frequency, the higher the inductance and skin effect. Beyond a certain range, the electricity emitted by the high-speed rotation of the generator becomes smaller and smaller.

Skynet believes that alternating current changes its direction repeatedly and its own loss is very large. The higher the frequency, the less energy it drives. If you want to study the energy and power of radio waves, you should enter the capacitive mode that emits radio waves instead of generating electricity. Electromagnetic induction mode.

The welding machine has changed from a heavy iron welding machine to a lightweight electronic welding machine. Its core technology is to use an inverter to change the current frequency from a 50 Hz power frequency to a transformer current of about 16 Hz, thereby greatly reducing the reactance effect and realizing the revolution of small transformers and large currents, thereby reducing The weight of the welding machine.

What if this principle is applied to generators and power transmission and transformation systems? Transformers of tens or hundreds of tons will no longer be used. Small transformers of several tons can be used for large tasks. This will greatly reduce the use of copper materials and the size of generators will also be reduced.

The working principle of this kind of generator is not complicated. A continuously variable transmission is added between the generator and the engine. Through the continuously variable transmission, the motor always works at the optimal speed without the occurrence of the generator The situation where the engine is shutting down even under the best condition, or the engine is working normally but the generator cannot work at the best condition.

When the engine speed drops and cannot work normally, the continuously variable transmission will automatically change the transmission ratio. When the generator speed picks up, the speed of the generator end remains unchanged, but the torque increases to resist the resistance when the generator increases the load. Ensure the engine works at optimal speed.

The terminal of this power generation system, after transformation and rectification, finally uses Edison's 110-volt 16.27 Hz low-frequency alternating current. It is different from the electricity system in any country in Europe and the United States, but the overall efficiency is the highest, especially when welding with reverse The transformer is omitted, just connect a small transformer. Mao Xiong is now very poor, and the old electric power industry can be said to be very rare. This change was so smooth that it could be said that this historic transformation was completed unconsciously.

This change not only means that for a long time in the future, the electrical appliances that Mao Xiong can use will only be those provided by Zhang Cheng, but also means that Western technological products are excluded from the system. Who will supply whom in the future? If we are on par, then let’s see who has greater fundamentals and technical advantages. If you don’t believe in my interstellar standards, you can’t beat your international standards.

In terms of military affairs, Zhang Cheng not only provided Russia with a large number of advanced weapons. A large amount of military infrastructure has also been built. Moscow, St. Petersburg, Volgograd and other cities are building airports. After these airports are completed, they will be covered by aircraft firepower within a radius of 2,000 kilometers, forming an absolute control of the air and sea. The St. Petersburg Air Force can cover the entire Baltic Sea, the White Sea and part of the Barents Sea, and Volgograd can cover the Black Sea, Caspian Sea and the Caucasus. Moscow Airport can cover the entire Eastern Europe, and the daily takeoff and landing capacity of each airport can reach more than 3,000 sorties.

An aircraft that looks exactly like the P38 from World War II is neatly parked at the temporary airport. The reason why I chose this aircraft is mainly because it is very cost-effective. This kind of aircraft is a single-wing aircraft with a large aspect ratio. It has a long range and a long time in the air. How much? Some glider properties. Although jets are faster and carry more cargo, the cost is not at the same level. It is undeniable that gliding is the most cost-effective at any time. The aerodynamic layout of later Scorpion drones is very similar to that of the P38.

The reason why this aircraft chooses a piston engine is not without other considerations, especially in terms of tanks. The power station cannot follow the troops forward. The piston internal combustion engine is an insurmountable obstacle in some aspects, and Zhang Cheng does not want to The large-scale use of magic crystals, especially the use of magic crystal mines as consumables in war, is much more cost-effective than using them in interstellar trade, so this aircraft also uses a piston engine.

However, even the piston engine is far ahead of this era and adopts many new technologies developed after the war. For example, the crankshaft mechanism and cam mechanism are eliminated, and a half-gear reciprocating mechanism is used. A piston has a cylinder at each end and a cylinder in the middle. Through the reciprocating small half-cycle gear of the piston, when multiple such mechanisms are connected in series with different ignition times, it becomes a stable energy output system, and at the same time, the cam valve structure is replaced by an electronically controlled valve. The superposition of the two makes its thermal engine efficiency reach 60%, which is almost close to the limit.
