The laboratory of electrolytic aluminum was completed, but it was completed in the laboratory, at any cost, and its price was still quite high in terms of the current cost of Ding Haijun, the reason is very simple, the cost of electricity remains high.

Aluminum is the highest content of metal materials in nature, not to mention the whole earth, even in the earth's crust, the amount is very large, but aluminum is easy to be oxidized, and even his oxide is easy to be oxidized and become other things, and the activity of aluminum is quite high, and it is not easy to be replaced.

In the early days, in order to replace aluminum, potassium was used, which also caused the high price of aluminum, that is, after the discovery of electrolytic aluminum, the price was gradually reduced.

In the era of the French Empire, why take an aluminum spoon, the reason why they are proud is not like it, aluminum, a newly discovered metal, his price is extremely high.

It can be said unceremoniously that most of the price of aluminum is on the electricity bill, the higher the electricity cost, the higher the price of aluminum, and the lower the electricity cost, the lower the price of aluminum.

Many people think that the price of electricity is quite cheap, in the 21st century, China's power generation ranks first in the world all year round, and the price of electricity is so low that it is a few cents per kilowatt-hour, and therefore, the price of aluminum has been reduced to a very low level.

What is the concept of the future, not to mention all kinds of clean power generation, wind power, solar energy, let's talk about thermal power, it should be the most consumed, because it needs fuel.

However, the progress of science and technology has made the energy efficiency ratio of coal power generation very high, and many public relations in the critical, supercritical, and ultra-supercritical have reached a high degree of research on thermal power plant units, and the standard coal used per kilowatt-hour of electricity has been reduced to about 260 grams, which is also the basis for cheap electricity.

At the very beginning, the price of electricity was quite expensive, not to mention the European countries, at the end of the 19th century, the beginning of the 20th century, the price of electricity in the concession was about 0.12 taels per kilowatt-hour, which refers to silver.

Even if it is converted to the silver price of the 21st century, 3 yuan per gram, 0.12 taels is as high as 6 grams, that is, 18 yuan per kilowatt-hour of electricity.

According to a 100-watt light bulb that illuminates 4 hours a day, 12 kilowatt-hours of electricity a month, which is 1.2 taels of silver, which was quite expensive for China at that time.

In the concession, that is, the electric lights used by the rich and noble, in this way, not every room can be turned on, on average, each room, the lighting cost is 1 tael, for dozens of rooms of large households, it is also a big expense.

The high cost of electricity also brings the high cost of aluminum, and even the key problem of electrolytic aluminum, the high cost of electricity is only one aspect, before the popularization of electricity, and even before the large-scale popularization of electricity, it is a thing that is a mirror in the sky.

The consumption of electrolytic aluminum for electrical energy is too large, and there will not be much electricity in the world at that time.

To a certain extent, aluminum is highly sought after, and is also known as a precious metal that replaces gold and silver, but with the revolution of electricity and the application of countless new technologies, the price of electricity is getting cheaper and cheaper.

Whether it is thermal power, wind power, water conservancy, or even nuclear power generator sets, they make the world's energy continue to climb the peak, higher and higher technology, and also make power generation cheaper and cheaper.

The research of aluminum alloy, of course, will be carried out, in the laboratory, the use of cards to speed up the research of aluminum alloy, this can be done, put into the factory mass production, or forget it.

The reason why aluminum alloy can be an important alloy under ferroalloy, the key is the quantity, the steel plant, if it does not have an output of 2 million tons, do not dare to easily set foot in the railway, the amount of energy to a certain extent, will produce qualitative changes, otherwise, the real high-hardness alloy, not nothing, in hundreds of millions of years, fell to the earth meteorite.

At high temperatures and pressures, some of the residues that eventually burn will be similar to those of high-hardness alloys, and their performance will be better.

In fact, in later generations, the price of various meteorites is high, on the one hand, because they are alien objects, containing many codes belonging to the universe, and have extremely high scientific value, on the other hand, it is precisely from the middle to find certain formulas.

Historically, almost all of the recorded weapons were made of these materials, but there were too few such materials

At the end of the Warring States Period, the Seven Heroes rose together, and in the end it was the Qin State that had the advantage, and the weapons of the Qin army were mostly bronze, which was one of the reasons for the opponents of the minority weapon-only theory, the Qin army defeated the iron with bronze, but he did not see that the smelting of iron tools was complicated, at the end of the Warring States Period, there were few blacksmiths who could master it, and those who could master it could almost be called famous craftsmen, such weapons, in the army, how many

Just like the steel weapons of the navy now, if this total amount is only used by high-ranking officers, then it will have no meaning, only popularization, only cheap, and large-scale use is the best.

The theory of weapons does not refer to a single weapon, but to popularize it, and only when the total quantity is high can it produce results.

After verifying the aluminum alloy, basically, it stopped, and there were still a few researchers researching, but the efficiency was much worse than before, and even Zhao Xin's guidance was very little.

In Zhao Xin's view, this is more of an accumulation, perhaps, lightweight aluminum alloy, on the ship, has a certain use, in the selection of steel and aluminum alloy, the weight advantage of aluminum alloy, will bring good changes, especially for the pursuit of speed clippers.

Distance and speed, this is relative, why the earth in the 21st century, will become a global village, radio, broadband, these can make the information on the other side of the ocean, can be transmitted at the same time, and the aircraft such a means of transportation, so that within 2 days, across the earth has become possible, under the developed transportation, the earth has become a village.

In the future, as long as the Ding Navy enters the ocean and develops the islands in Southeast Asia and the Pacific Ocean, distance will become an important issue, or the current speed of the Chinese sailing ship 4 knots, there is no way to solve the problem, but it will make the developed outer islands, gradually detached, only higher speed, for example, an average of about 14 knots of flying clippers, can shorten the distance, so that the cohesion of the whole country is stronger.

It's still a little early to talk about this now, the Ding Navy has gained double the speed just by renovating the sailboat, and the flying clipper ship is something that will only be paid attention to later.

While 12 researchers are studying step by step, the success of aluminum alloy is also widely used.

From the basic verification of electricity, Zhao Xin only gave the basic formula, and occasionally paid attention to it, the initial electricity was just to verify the distance from some middle school textbooks, and the completion of electrolytic aluminum, even if it was only a small amount of completion in the experiment, also represented the development of electricity towards practicality.

Zhao Xin does not have the ability to popularize electricity on a large scale, nor does he have the ability to directly cross the internal combustion engine of the steam engine and directly enter the electric motor to provide more powerful power for the Ding Navy, but lighting is a problem that needs to be solved urgently.

Dark night, for the era before the Northern Song Dynasty, it was the night, it was the invisible era, the day was the sunrise and ploughing, the night, it was the sunset, and the flame lighting appeared very early, because it was dangerous and expensive, not the usual method.

The city that never sleeps in Tokyo in the Northern Song Dynasty is the result of the development of candles to a certain extent, and it is also the result of the prosperity of the Northern Song Dynasty.

In Dingjun, industrial efficiency is required, so the dark night must be overcome, some key factories, with three shifts and four shifts, people and machines do not stop, so as to create higher labor efficiency.

Candles, used in entertainment places, there is not much problem, used in factories, it is not particularly suitable, for example, such as flour mills, cement factories, such as dusty places, open flames are very dangerous.

The appearance of kerosene lamps is good for outdoor and windy places, but it is not suitable for use in these places, no matter how unique they are, they must also be burned and use oxygen, once in contact with dust, it is easy to cause danger.

Not to mention all kinds of laboratories, most of the experiments, the requirements for flame and temperature are somewhat high, the more sophisticated the more so, especially some experiments with little color change, even in the daytime, not every moment can be done, only at noon, when the visibility is high, can be done.

When the electricity can be electrolyzed aluminum, then it is not very far from the lighting, Zhao Xin inquired in detail about the power of the generator, especially the performance comparison between various magnets, looking for the possibility of expansion, and on the basis of the simplest generator, began to improve.

Larger magnets, natural no, are not very large, but through chemical synthesis, ferric oxide, just calcined between iron oxide and iron powder, through a certain experiment, made a large magnet, and then the wire and transmission device.

Closed conductor, rotate, there are many problems, then let the magnet rotate, without more powerful power under the premise, animal power has become an inevitable choice, at most to make a fuss on the transmission device, so that the efficiency is higher.

However, under such various efforts, in the end, an animal-pulled generator has an installed capacity of about 3 kilowatts.

3 kilowatts, or under the joint action of dozens of horses, the largest generator set in the Ding Navy at present, that is to say, according to an hour, each hour is just 3 kilowatts of electricity, 72 kilowatts a day, counting the whole year, that is, more than 20,000 kilowatt-hours.

This efficiency, in the 21st century, basically, is enough for three or four families to use, and it is not a difficult thing for ordinary families to use 500 kilowatt-hours of electricity in summer, but in this era, if you drive a light bulb, it can be used by dozens of laboratories.

With enough electricity, the bulb is logical, without a good smelting conditions, and the premise of the wire drawing process, tungsten wire is definitely impossible, the information age, carbon fiber this thing.

As many Chinese primary school students know, Edison is such a great inventor, and Edison is the inventor of the light bulb.

In order to invent the light bulb, he spent a lot of energy and experimented with countless materials, and finally found the material of bamboo charcoal fiber.

This bowl of chicken soup, I don't know how many people believe it, the genius he said is one percent talent and ninety-nine percent sweat, and this sentence has also inspired countless people.

As a historian, Zhao Xin is willing to take many things seriously, in fact, in the era of Baidu, many things about Edison are available on the Internet, and they are very detailed, but the vast majority of people are unwilling to inquire with them.

I really want to say, Edison, I'm afraid he was the twenty-third person to invent the light bulb.

In real history, Edison was just a person who did not graduate from elementary school, and if you still have historical origins, Edison may have been an inventor, but after accumulating his first fortune, he became a patent merchant, just like the subject of later generations, he was the boss with funds, and there were naturally all kinds of research dogs and doctors dogs below, and their achievements and inventions naturally became his.

As for the invention of the light bulb, the original idea came from an Englishman named Joseph Swan.

As early as 1848, Swann began to study light bulbs, and also tried several materials, from platinum, to various metals, and then finally determined the body of carbon, the calamium glass cover is pumped into a vacuum, and the carbon bulb of horseshoe has a final service life of only 13.5 hours.

The year was 1848, and Edison was only one year old when Swann invented this.

However, at that time, the power generation technology was not up to standard, and the various voltages were unstable, and the bulb with a service life of only 13.5 hours could not be developed.

At best, Edison was an improved light bulb, based on Swan's invention, better use of electricity conditions, and searched for more suitable carbon fiber, and finally searched for countless materials, and found a bamboo light bulb.

The reliability of the bamboo light bulb has been greatly improved, it has reached 170 hours at the beginning, and it can basically be used, after a series of improvements, such as finding better bamboo, and finally extending this life to 1200 hours.

Standing on the shoulders of giants, Zhao Xin knew that this was a Japanese bamboo, but in the popular science materials, it was not clear what kind of bamboo this is, there was no way, only to make comparisons, many bamboos in Japan were transplanted from China, in the Northern Song Dynasty, among all kinds of bamboo, one by one, and finally made a more durable bulb, which can be used for more than 300 hours.

This is enough, according to the daily lighting of 6 hours to calculate, can be used for almost 50 days, this use efficiency is acceptable, about 100 watts of bulbs, may not be able to compare with the later generations of energy-saving lamps or incandescent lamps, this brightness compared to candles, compared to kerosene lamps, has been much brighter, when the laboratory is brighter, the overall efficiency, also increased.
