Chapter 194: Semiconductors.


    After that, innovative ideas continued to emerge.


    There was a reason why the so-called experts gathered together, and it was also thanks to Golden Lake, who clearly presented the problems that had to be solved first.


    But the decisive reason for shortening the time was thepetitive spirit.


    Damn. The other parts are already showing such results, what are we doing?


    For space exploration, all parts of the research had to achieve results.


    If there was a part thatgged behind, the time would be dyed ordingly.


    The experts joined this research with a promise of a hefty sry.


    That meant they were famous people.


    But being behind others was hard to ept for the experts who had pride.


    Once the atmosphere of the research institute burned up, innovation was achieved.


    So far, the rockets have been very inefficient because thermal energy is discharged through the exhaust port. If we can only utilize this wasted thermal energy, the power of the rocket engine will change dramatically.


    The rocket engine part worked hard to utilize the wasted thermal energy and created a supersonic nozzle.


    When attached to thebustion chamber of the rocket engine, the nozzle could eject the hot gas from thebustion chamber as a jet stream.


    Oh!


    This was the answer. At least it seems like the thrust has increased by twice, right? The engine efficiency has skyrocketed, hasnt it?


    Eventually, in the rocket engine part, Golden Lakes suggestion of dramatically increasing the efficiency of the rocket engine was achieved.


    Not only that, but they also finally made a gyroscope that kept the axis of rotation in the same direction even if they tilted their body in another direction, and finished all the basicunch preparations.


    With this, Golden Lake asked earnestly to the researchers beforeunching a formalunch experiment.


    You all know this, but rocketunch experiments are very dangerous. During a moment when a huge amount of fuel loaded on a rocket isbusted inrge quantities, even a small defect in one part can cause the rocket to explode on the spot. So I will not allow any carelessness duringunch. We all have to share the glory of achieving the first space exploration. Do you understand?


    Yes, sir!


    Despite Golden Lakes worries, the rocket wasunched.


    5, 4, 3, 2, 1. Launch!


    Receiving everyones attention, finally, the rocket engraved with all the blood and sweat of all researchers flew up loudly into the sky.


    Oh!


    Its flying high!


    The firstunch experiment seemed to mock countless worries and flew up to the distant sky.


    But


    Boom!


    Theunched rocket ended its life by exploding brilliantly in the atmosphere.


    At this, the researchers bowed their heads sadly.


    Ha Is it a failure?


    The most expensive fireworks show in the world. How much is that?


    Well. It went pretty high for a first try.


    But Golden Lake and the researchers thought positively.


    Flying high in the sky was half a sess and it was very rare for research to be sessful at once.


    Anyway, this research had very abundant funds like an inexhaustible spring. T


    hey could just do it again.


    The researchers continued to improve their rockets based on research data obtained fromunch experiments.


    ***


    Golden Lake was directly involved in all parts.


    And he also suggested many decisive ideas.


    The gyroscope also started from Golden Lakes idea.


    But there was a part that Golden Lake cared about most.


    It was none other than the calctor part.


    From the beginning, Golden Lake clearly stated in front of mathematicians and mechanical engineers who were called experts.


    We will create an all-purpose calctor that has never existed in the world before.


    A calctor Well, mechanical calctors used now are not very good in performance. If such a thing is made, it will be easy to do a lot of calctions needed for rocketunch.


    Thats right.


    Golden Lake admitted calmly.


    In fact, not only rockets but also excellent calctors were very much needed by Earthbound Group.


    Earthbound Group was a leader in aviation industry.


    And airnes also required a lot of calctions.


    Isnt there an increase in demand for aviation across empires and globally?


    The scale of calctions that will be entered in future will increase day by day.


    There are too many aviation idents due to minor calction errors.


    Due to nature of aviation idents, it is very difficult to find survivors once they crash.


    Even though death rate from aviation idents was lower than car idents, people were anxious about airnes because of this reason.


    To poprize airnes more than now, they had to lower ident rate and eventually needed an excellent calctor again.


    Golden Lake had roughly finished his idea while preparing for research.


    So he dered confidently.


    We will use a huge amount of vacuum tubes to make an electronic calctor.


    Us Using vacuum tubes?


    Yes.


    How many vacuum tubes do you n to use


    At least we have to use more than ten thousand tubes to make calctions possible as much as we want, dont we?


    Hmm


    At this time, vacuum tubes were used in many ways.


    Everything used in radios and televisions was a kind of vacuum tube.


    The experts gathered here couldnt not know about vacuum tubes.


    Thats why they sighed.


    Is that realistic? The weight and volume will be huge, and the power and heat generated will be no joke.


    Thats probably true. But I think its worth trying. So that when a better material is developed in the future, we can apply it right away.


    Golden Lake didnt not know the problems of the electronic calctor he was trying to make now.


    But Golden Lake thought it was better to try first.


    If you dont challenge, innovation wont happen.


    Golden Lakes life had been a series of challenges.


    That was how he achieved great innovations in various fields, from automobiles to aviation, from advanced materials to electronics.


    He eventually connected a huge number of vacuum tubes and created an electronic calctor.


    At the same time, Golden Lake also conducted other experiments.


    I need to make something that can rece the vacuum tubes.


    None of the researchers thought that the electronic calctor they were making would be poprized. It was too inefficient for that.


    Therefore, the development of a substitute for vacuum tubes was essential for the dissemination of electronic calctors.


    The data from the development of the cutting-edge material, duralumin, was very helpful for this.


    At that time, they had obtained data on various materials.


    Golden Lake poured a lot of money into the development of electronic calctors and vacuum tube substitutes.


    The first thing that was made was an electronic calctor.


    This is amazing.


    This was Golden Lakes first impression when he saw thepleted electronic calctor.


    Later, Golden Lakes electronic calctor, which was called the first electronicputer, was born.


    It used 20,000 vacuum tubes.


    It was 30 meters long and weighed over 30 tons.


    After that, Golden Lake tried to operate this monstrous calctor in earnest.


    And the expected problems came out one after another.


    The performance is not bad, but


    The sight of a huge number of vacuum tubes glowing red and working at the same time was quite beautiful.


    However, it consumed 150KW of electricity per operation, and a huge cooling device had to be used to cool down the enormous heat.


    The biggest problem was the lifespan of the vacuum tubes.


    Damn. Its broken again?


    Where is it this time?


    Over there!


    Ugh This is a waste of money.


    The vacuum tubes had a short lifespan and broke easily.


    As a result, many people had to wait for the recement of the vacuum tubes.


    As a result, the time spent repairing this electronic calctor was four times longer than the actual usage time.


    As expected.


    Golden Lake shrugged his shoulders as he looked at this unnecessarilyrge electronic calctor.


    But thanks to this, I collected a lot of data. And I saw the potential of electronic calctors.


    Golden Lake tried various things with mathematicians using this device.


    At first, they used an external program method, where they had to manually insert wires for each calctionmand.


    But Golden Lake soon found another way.


    It seems more efficient to make a memory device and store the program in advance.


    Based on this, he made a memory device.


    And he performed one program instruction at a time from the primary memory device where he stored the program and data.


    He also adopted binary system and verified its possibility.


    Its not bad for what it is.


    He encountered many problems through trial and error, but the performance of the calctor itself was quite good.


    Thanks to this, it helped a lot with the calctions needed for rocket experiments.


    ***


    Opportunityes to those who are prepared.


    At first nce, Golden Lakes research method seemed like a waste.


    The huge budget that he had wondered if he could use it all before was rapidly decreasing.


    That was proof of that.


    But because of that, a historic invention was made at Golden Lakesboratory.


    This is a very interesting material.


    As mentioned earlier, Golden Lake encountered various materials since the development of duralumin.


    Among them, germanium gave him a fresh feeling.


    It had a characteristic that electricity flowed or did not flow depending on external stimuli.


    Hmm. If I use this well


    Golden Lake felt something intense from germanium.


    So he used germanium for various experiments.


    He continued his experiments while making an electronic calctor with vacuum tubes.


    But he also improved it.


    And his efforts paid off.


    This is!


    Oh my God!


    It was none other than a transistor made with germanium.


    The researchers were greatly impressed by its performance and role.


    Golden Lake was also surprised by the transistor he made.


    And he started to find out more about its properties.


    The results were amazing.


    It could amplify weak signals and use the characteristics of semiconductors to switch roles.


    Golden Lake focused on thetter among these two performances.


    The transistor was much smaller than the vacuum tube.


    That meant that it could greatly reduce size, power consumption, and price.


    Of course, the first developed transistor had many problems, but Golden Lake and his excellent researchers improved it intensively.


    And finally they reached the point where they could rece vacuum tubes with transistors.


    Hahaha! This is iparable to what I made with vacuum tubes!


    With this I can do not only calctions but also various other tasks.


    Theputer made with transistors was much smaller than the one with vacuum tubes.


    And it consumed much less electricity.


    Most importantly, it was more reliable because it broke less.


    It was a great sess.


    Thus, the era of second-generationputers opened, and the history of semiconductors began.


    After that, semiconductors changed the world little by little.


    Ironically, this invention had a much greater impact than the main research of space exploration.


    Thanks to this, Golden Lake became the developer of the firstputer and semiconductors.


    Not long after the second-generationputer wasmercialized, he alsounched a rocket beyond space for the first time.


    He wasparable to Kim Ki-woos achievements.


    He built a huge tower of gold.
