…

This is also the reason why Liu Tong still gave up the steam engine when he knew that the etching node researched by Huang Yueying could restrain the heat loss.

Unless the tracks are spread all over the country, and there are corresponding equipment and facilities, and there are a large number of manpower, installation and transportation.

In that case, a significant reduction in the cost of coal, at least on the surface, would allow the steam engine to be used on a large scale.

Although it works tirelessly and does not complain, relying on the high intensity after temperature and relieving, the heat energy restricts the full combustion in the future, and will not produce foreign substances such as carbon deposits.

It allows the steam engine to work without rest for twelve hours a day.

But under this premise, how many materials, manpower and financial resources have to be wasted.

At this stage, they do not meet this condition at all, not only to stabilize Xuzhou and Jizhou, but also to smoothly win Bingzhou and Youzhou under the condition of being as peaceful as possible.

It's okay to merge with the state, as long as Lu Bu nods, it's not a big problem, but Youzhou, just with the relationship between Gongsun Chan and Youzhou Mu Liu Yu, it's enough to give people a headache.

And many things, even if they are arranged and arranged in advance, will inevitably be unified in the end before they can be implemented on a large scale.

Of course, for technical reasons and considerations, if the Heaven and Earth Spirit Qi Steam Engine can be completely done before the unification of the world, then the problem will be easier.

Consuming Heaven and Earth Essence Qi is much stronger than consuming coal, at least one is invisible Heaven and Earth Essence Qi, and the other is visible coal to the naked eye.

Which costs more?

As long as you can make a heaven and earth spirit gas steam engine and can manufacture it on a large scale, you can also remove manpower.

A lot of long-distance transportation and bulk cargo transportation will be directly handed over to the heaven and earth spirit gas steam engine to solve.

But that kind of thing has nothing to do with Lu Jun.

The steam engine that can produce power without sleep, even if it has a huge consumption, is an excellent substitute in Lu Jun's eyes.

Anyway, compared to the expensive warships, how much money can be spent on the consumption of coal?

The owner who can afford to build a 5,000-ton steel battleship will be afraid of a little coal consumption?

Regardless of whether there is cloud gas suppression or not, there is an output of several hundred tons of power, which is more than enough to propel a warship with a base load of more than 5,000 tons.

If it is combined with the corresponding Cloud Qi Secret Technique, its speed will also be very fast.

The most important thing is to be able to run without sleep.

Of course, for the sake of stability, Lu Jun did not choose to install one, but wanted to install two.

But it's a pity that there is only one in the Qingzhou mine, and as for the excess, it has to be made fresh.

Even when the construction center received such an order, it was in a state of confusion.

After a long time, I remembered that there was such a thing as a steam engine, and then fished out the corresponding drawings and asked my superiors.

That is, Lu Min, and it was at that time that Lu Min discovered Lu Jun and Gongsun Yu's change in the power of the ship.

For Lu Jun's request, I was even more surprised.

You must know that the steam engine he designed, under normal circumstances, can even output tens of thousands of horsepower by relying on etching constraints and full combustion.

Of course, limited to horses of the normal world, not horses of this world.

If you switch to this world, the value will drop a lot.

But there's nothing surprising about the basic power delivery.

Theoretically, a steam engine is enough to meet the power needs of that steel battleship.

And because of etching and cloud warming, the coal consumption of the steam engine is much less than that under normal conditions under full combustion.

Of course, even if it is much less, it is not comparable to the inhuman force of this world.

Whether it was Zhao Yun's single-man army attacking and opening mines, or Lu Bu wielding Fang Tian's halberd to open mountains and dig coal mines in Bingzhou, it was not something that a steam engine could do.

After careful consideration, Lu Min finally decided to build another large steam engine for safety and just in case, and then deliver it to Lu Jun and Gongsun Yu.

Not only that, but the accompanying boiler heating etching and cooling etching after the steam power is used up are also delivered, which further promotes the acceleration of the cycle and reduces the volume of the steam engine.

It makes it much smaller than a normal 10,000-horsepower steam engine, but even to that extent, it doesn't mean much.

After all, it's not a big piece of machinery that one or two people can take away.

However, Lu Jun didn't care about these at all, and directly relied on the position reserved in advance, put the corresponding steam engine in, and then started the construction of the main body.

However, at the time of solving the problem of power, when the construction of the ship was about to be completed, a new problem arose.

One comes from the positioning of the battleship itself, which is a problem.

A battleship of hundreds of meters, with a high altitude, divided into multiple levels, with a variety of isolation silos, and these isolation silos are made of steel and wood planks.

Even for the outlet of the steam, two relatively small vapor smoke vents are reserved.

Although the etching can be fully combusted, the gas that can be sprayed out of the chimney will not be gases other than the normal vapor.

But just in case, two smaller steam chimneys remained.

There are even some sails stored in the boat, which can be used temporarily to gain some power after losing other power.

Lu Jun and Gongsun Yu, relying on the previous experience of Gan Ning and Tai Shici and others at sea, have added a lot of safety facilities.

All of this seems to be very good, but there is a huge problem, a seemingly simple but very fatal problem - and that is communication!

For a vessel of the same size, a fishing vessel does not need to be concerned about this aspect at all.

Even if communication relies on roaring, running and spreading, it is just a waste of time, and it doesn't matter to the fishing boat.

But for a warship, if it is really on the battlefield, it is also very important to convey orders in a timely manner.

And this kind of steel battleship means that when orders are transmitted within the team, it is necessary to give up the situation that communication relies on roaring and orders rely on flags.

Because that's too slow, so slow that the order is delivered, I'm afraid that new changes have already appeared.

And it was such a simple question that bothered Lu Jun and Gongsun Yu for a long time.

Even though the ship was nearing completion, they were slow to deliver the letter.

After asking Ganning for help, the actual test was conducted.

Relying on the ability of the internal qi to detach from the body, it is indeed possible to penetrate the ship and convey the order, but that means that all soldiers will receive this order.

This means that there will be multiple propagation of commands, repetition of commands, and so on.
