11. Do everything possible

After five days, Yang Tiehui's test first had the results, the results were not very satisfactory, it can produce a certain amount of energy, but the amount of these energies is not large, and the cost of investment is too large, so big that it is completely uneconomical at present, and this plan is scrapped.

Yang Tiehui was a little uneasy and pleaded guilty to Han Wenzheng, Han Wenzheng smiled and said: "Tiehui, if every plan can be successful, then wouldn't it be easy for us to succeed, don't take temporary failure to heart, don't have any ideological baggage, believe in yourself, and believe that you will definitely come up with a better way for your father." "Father, don't worry, I will. "Okay, go to work. "Father, I take my leave, you must not be too tired. Yang Tiehui took his leave and left.

On the contrary, Jiang Tieying's proposal was successful, although the energy obtained by the wind blowing by each engine is only 20 kilowatts of power, but the energy of 2,000 engines is 40,000 kilowatts per hour, which is not less, it is a small supplement, although it is not much, but it is finally a little gain, at least, the 2,000 engines made by Qian Tiexin will not become scrap metal.

With the input of many excavators, the excavation speed of the Datong Canal has been accelerated a lot, after all, these machines are always much faster than manpower or organs digging by hand, which is also a good thing.

With the progress of steelmaking technology, now, the daily output of smelting metals such as steelmaking has reached about ten tons, this output is not a problem at all at this stage, as for other resources, it is not a problem, only energy makes everyone helpless, it is really impossible to find better, more convenient, and more long-term use of energy, which makes everyone want to break their heads and find no good way.

These days, everyone has come up with a way, but, after many tests, it was found that it did not work, and each method failed, which also made everyone slowly discouraged, and they were too lazy to think about it, and only hoped that after the Datong Canal was completed, it should be the fastest plan.

Han Wen was sitting on the chair, without saying a word, Qiushui said: "Husband, forget it, now, we have thought of all the ways we can think of and tried them, but it still doesn't work." "I know the way, but, now, it's the energy problem stuck here, Shui'er, I'm not worried about upgrading to the first level now, I'm worrying about the future, now, it has been proved that we can't use electricity as an energy source before the thirteenth level, so can the coal in the Datong Coal Mine really allow us to go up to the thirteenth level?" Also, I believe that in the future, it is not only the people who need energy to make people, but also many other aspects that need energy, if we can't find a feasible source of energy, the problem of energy will always be bothering us, so even if it is difficult, I have to think about it until I come up with a way, I don't believe that there is really no better way to solve energy in this universe. ”

Qiushui said: "But, husband, we have already tried all the methods we can use, wind energy, energy is too little, solar energy, the power per unit is too low, and geothermal energy, we don't have it here, as for other methods, they have been proven to be ineffective, what other ways can we think of?" "Husband, sometimes, people can't get into the horns of the bull, and sometimes manpower is poor. ”

Han Wenzheng also knew that what Lu Dao Qiushui said made sense, but he was always unwilling.

One day, Han Wenzheng suddenly thought of something and found Yang Tiehui, Yang Tiehui listened to Han Wenzheng's idea and said: "Father, it's not impossible to make hydrogen, it's just that we don't have so much equipment, besides, the amount of hydrogen produced in this way is also limited, and there is no way to come in handy." "So think about it, is there any way to produce hydrogen in large quantities?"

Yes, Han Wenzheng thought of the way is to make hydrogen, as everyone knows, water is composed of hydrogen and oxygen, after direct current can be decomposed hydrogen and oxygen, the mass ratio is one to eight, that is to say, after decomposing a cubic meter of water, you can get about 110 kilograms of hydrogen, and the combustion value of hydrogen is 143 million joules per kilogram, which is equivalent to 38.9 kilowatt-hours of electricity, which is the highest among all gases, and the purity of hydrogen obtained by electrolysis of water is as high as 99%, which can be regarded as an ideal energy sourceAs for electricity, there is, so the key is that if you can convert electricity into direct current, it can be used to produce hydrogen.

After three days of research, Yang Tiehui came to Han Wenzheng very frustrated: "Father, if it is a small amount of hydrogen, it is definitely not a problem, I can make a small DC transformer, but if I want to produce a large amount of hydrogen, which can convert hydrogen into a large amount of energy, it is definitely not a problem that I can solve now." ”

Han Wenzheng patted him on the shoulder and said: "Xiaohui, don't be frustrated, maybe it's for your father's attention, this itself is beyond the difficulty of your ability to solve the problem, so it doesn't matter if it doesn't work, wait for me to find a way" Yang Tiehui said: "Father, sometimes don't be too persistent, at this stage, we may really have no way to find a better solution, we can only wait for the Datong Canal to be completed after the coal is transported, and my father doesn't have to think too much." ”

Han Wenzheng sent Yang Tiehui away, sighed lightly and said, "Alas, it seems that we still have no choice." Qiushui said on the side: "Husband, I have an idea, but the chance of success is not great." "What are the ideas?" "This is the pumping machine plan you proposed, although this plan can produce not much energy, but I believe that if the number of pumping machines is large enough, it should not be less than the energy that can be generated by the 'Wangfei Bridge'. ”

Han Wenzheng smiled bitterly and said, "Do you want to go around or go back to the pumping machine, but, Shui'er, can you tell me more about your thoughts?" My design is designed according to the pumping height of the pump, according to the calculation of Qian Tiexin on the day, the pumping machine should be able to send water to 100 meters high, we do not need to use multi-stage pumping, just a level of pumping, there should be a height of 100 meters should not be much worse, if we just pump water from the river, the distance is too far, the number of water pipes needed is really more, not cost-effective, so, my plan is to dig a section of canal from the river to the energy pool, all the way to the energy pool, so that the distance of pumping water is greatly shortened。 ”

Han Wenzheng came to a little interested and said, "Shui'er, continue." "Our Yanhuang City is 20 meters above the water surface, so that we can dig the canal in four levels, the first level is the deepest, is the river channel, the second level is five meters above the water surface, the third level is seven meters above the water surface, and the fourth level is nine meters above the water surface, so that it can be used to put the pump, so that the most pumps can be accommodated in the smallest space, and the soil from the canal can be used to build a large pool to hold the pumped water, and then use a large water pipe to send the water to the energy pool, and that's it. ”

Han Wenzheng took a pen and paper, drew a sketch according to what Qiushui said, and said, "Shui'er, is your plan basically like this?" "How much energy can be generated?" "The engine power of the iron core is 100 kilowatts, and we don't use a generator, just change the generator to a pumping machine, directly use the wind wheel to drive the way, so that the number of revolutions of the pumping machine should be very high, and the power should be able to reach about 60 kilowatts, so that every hour, we can send 20 cubic meters of water to a height of 100 meters, and if we have 9,000 pumping machines, it should be equivalent to the energy that can be generated by the 'Wangfei Bridge'." Qiushui also reported the results of the calculations.

Han Wenzheng smiled bitterly and said: "9,000 units, my good wife, 9,000 engines plus 9,000 pumps, plus a large number of water pipes, these are huge consumption, besides, with our current production energy, it will take more than three years to complete this work alone, do you think it is worth it?"

Qiushui was speechless, yes, it was indeed not worth spending three years to do these work, and the damage rate of these facilities was also relatively high, so although this plan had a certain feasibility, it was not very practical, and even she herself did not think that this project was worth doing.

Qiushui said: "Husband, don't think about it, we can think of ways have already been thought of, there should be no other way to think of, or find a way to make the construction of the Datong Canal faster is the most practical, otherwise, our energy accumulation speed is not fast, you are a smart person, you should understand." "Yes, I still don't think too much, it's useless to think too much. ”

After Han Wenzheng spent five days inspecting the construction site of the Datong Canal, he felt very satisfied, Zhao Tieyun and Sun Tiejian were both able to complete this task alone, that is to say, it had nothing to do with whether he was there or not.

Han Wenzheng and Qiushui spent another five days walking through all the construction sites, including grain planting areas, stone mining areas, steelmaking areas, coal areas and other places, and they felt that there was no problem, everything was very good, and the children had already done very well, so they didn't have to worry about the two of them, for this, Han Wenzheng praised everyone greatly, which made everyone very happy.

Qiushui also praised them, however, her praise method is to make a delicious meal, let everyone go back to Yanhuang City to eat, this is also a big dinner, sometimes, also need everyone to walk together, have a meal, drink some wine, contact feelings, this, Qiushui did a very good job, a meal, everyone drank a little high, one by one pulled Han Wenzheng, asked Han Wenzheng to sing, poor Han Wenzheng, learned everything, but only did not learn to sing, was forced by a group of children to sing only two songs, the five tones did not exist He sang too ugly, so that all the children sang down, but also made everyone laugh until their stomachs hurt.

One night ended in laughter, Han Wenzheng hugged his wife and said with a smile: "Shui'er, you are so smart, you really know my thoughts." "Who made me your wife?" Qiu Shui smiled.
