Eugénie did want to dwell on it for a while, but when she returned from the garden of Sto, Madame Montijo told her the sad news that she had duly replied to the Emperor of France and agreed to the marriage. When it was over, Eugenie fell on the chair, completely devoid of the joy of becoming the queen, it seemed that she had no choice, releasing the doves of the Emperor of France was not something ordinary people could do, and her heart was not big enough to become a superman. She took out the toothpaste sent by the local tyrant to observe, alas, this is probably the last box.

In the French-speaking world, the news of the Emperor's imminent wedding spread rapidly, and Tang Ning opened the French Republican newspaper to take a look, and was stunned, it seems that the countess still did not resist the temptation of being the empress, hey, the little baron was decisively defeated by the emperor. An amateur literature enthusiast, Don, never went to Little Holland House again.

Hugo, Alexandre Dumas, Faraday, Prince Albert, Foster and other good friends have taken the opportunity to visit the frustrated local tyrants, and I heard that the local tyrant baron is very negative now, and he doesn't go out much. Hugo, Alexandre Dumas and Foster want to introduce Downing to beautiful actresses, Faraday jokes that when his daughter Alice Phil grows up, Prince Albert says that there are several Germanic aristocratic girls in his hometown who want to marry big tyrants and want to be blind, do you want to see them?

Hmph, these guys, there is no sincerity at all, there is nothing to say without photos...... Well, it's time to get down to business, and since the oxygen and acetylene production lines are ripe, it's time to consider the main part of heavy industry - shipbuilding.

Downing met with the famous engineering scientist Brunel in the Syàn Room of the Si Tuo Garden. This great engineer has important engineering innovations in railways, subways, bridges, and shipbuilding, and is one of the most prominent figures in British engineering and one of the advisors to the International Industrial Exposition.

It is precisely because of Brunel's fame and innovative spirit that he dares to make his own set of standards for railway tracks, and the width of the Great Western Railway he presided over is different from others.

This guy even engaged in vacuum tube traffic that was unsuccessful after a hundred years, with a speed of up to 100 kilometers per hour, and was gnawed by rats after more than a year, so he decisively stopped his loss and withdrew.

After the opening of the Great Western Railway, Brunel felt that it should expand its access, sailing directly from the port of Bristol in the United Kingdom to New York, and the world's first real transatlantic ocean-going giant ship was also named the Great West. The original ocean-going ship with a registered gross tonnage of only 800 tons could not meet the demand for transatlanticism, and the Great Western was suddenly raised to 1,350 tons. The Great Western Steamship Company was founded precisely for the transatlantic ocean, and their second ship, the Great Britain, was even more commendable in terms of engineering technology, for the first time combining underwater propeller and iron-hulled technology, with a displacement of 3,675 tons.

The development of science and technology always starts from the most intuitive, the first propeller is to imitate human paddling, placed on both sides of the hull, not to mention the lack of force surface, but also easy to be damaged when mooring, the Britannia originally used this design, Brunel happened to encounter a boat using underwater propellers and surface paddle boat competition, and instantly decided to switch to underwater propellers.

Lao Bu was so innovative that he often overlooked commercial feasibility, and the Great Britannia, originally budgeted for £70,000, but it cost 11. 70,000 yuan, the cost was too high, and after a period of operation, it did not keep the postal contract, and in 1846 it ran aground due to navigation errors and withdrew from commercial operations.

When it comes to shipbuilding, Downing himself has only used a three-dimensional printer to build the parts of a warship of equal proportions, and to really use the innovative process of welding, he must hire an industrialist like Brubnell.

There is no nonsense to talk about with an industrialist like Lao Bu, so he asked his assistant to bring protective clothing and directly took him to see the handsome scene of acetylene burning in pure oxygen and cutting steel plates with high-temperature flames.

Yes, it's like cutting tofu with a treasure knife.

Lao Bu's eyes straightened when he saw it, and there were words in his mouth: "Miraculous...... Amazing ......"

Downing: "There's more amazing to come. Then I took Lao Bu to see acetylene welding, and a few skilled craftsmen came to perform a wonderful show for Lao Bu.

Brunel was instantly excited: "Is this a new riveting method?" It's so good for this flame to be used here! ”

Downing corrected him: "It's called welding. The high temperatures generated by the high-voltage arc are more reliable and safer, but our electrical process is not yet up to the level of welding, and we have to use acetylene welding for the time being. We have tested that such welded plates are almost as strong as steel plates without seams. Is there any interest in building ships in this way, sir? ”

Brunel couldn't help but be overjoyed: "I'm so interested! It's not just about shipbuilding, it's about changing from now on, railways, bridges, buildings...... It's a great invention! ”

Tang Ning: "I want to build a large dock that can build a 50,000-ton ship, and the whole dock has a roof to ensure that work can start within 24 hours." ”

Brunel was stunned when he heard this, his "great, world's largest Britannia" is only more than 3,000 tons, and this lord's goal is 50,000 tons, and there is a top dock? How much does it cost? Although Lao Bu doesn't pay much attention to commercial operations, he also knows that his 3,000-ton Britannia is already "too advanced", and it is not as cheap as the more than 1,000-ton Great Western to make money, and this 50,000-ton ship may be built at a loss. The bigger question is whether such a large ship can move? This lord didn't think that if the ship could be built, it would be able to swim, right?

"Are you serious?" Of course, Lao Bu didn't dare to ask if this great inventor, whose fame had overshadowed him, knew how to build a ship. （http：／／.）。

Downing showed off his welding, said "follow me," and showed him another masterpiece—the steam turbine engine.

The turbine is just a small, scale-sized acetate machine, about the size of a dining table. Its main mechanism is to control the steam flow through a fixed "stator" fan, and after doing work on the first stage "rotor" fan, it is transmitted to the second stage, and the stator of the second stage is then turned back, and the back sector needs a larger sector to effectively convert power due to the decrease in air pressure, so the multi-stage turbine we see is always the last few stages with larger diameters.

Watt's improved steam engine is reciprocating, i.e., the piston moves back and forth as the steam expands and contracts. Whereas, the power source of a ship, the propeller, is rotational motion. The Watt steam engine needs a guò connecting rod system to convert the reciprocating motion into a rotary action, which has an additional conversion process, so the efficiency is not so high, and the smoothness is not as smooth as the steam power is directly transmitted to the propeller through the guò turbine. If the smoothness is high, the propeller can move more streamlined back waves, and the efficiency is higher.

Downing asked his assistant to turn on the reciprocating steam engine that consumed the same consumption, and the two machines cut the magnetic coil at the same time to generate electricity, and the result was obviously that the turbine was superior. Then two small boats with different engines were taken to the pool for testing, and soon the turbine steamboat threw off a large part of the ordinary motorboat and won completely.

The two revolutionary improvements in hull and power can't help but be unconvinced, how could Brunel, who loves innovation, let such an epoch-making ship fall into the hands of others, so the director of Downing's shipyard is considered to have fallen. This dock Downing continued to work with Paxton, who was happy to work together, and was likely to be called "Crystal Dockyard".
