Carlo's thoughts are completely unaware of the Prime Minister's thoughts now, but lately he has been very full, discussing national affairs during the day and personal matters at night, which is not too comfortable.

The only thing that is a little bad is that my legs are a little weak after a long time. But Carlo is happy, youth is the capital, and he can come back after a few days of rest.

In this way, the time came to 1885, first of all, the Sino-French war came to an end, the two governments signed and ratified the peace treaty, and the smoke of gunpowder over the Far East was completely dissipated.

The Berlin conference on Africa was also over, in which Italy was given only the Greater Somalia region of East Africa as its sphere of influence. This did not affect Italy much, because at the moment Italy simply did not have the strength to carry out the next colonial development immediately. After all, Italy has suffered heavy losses in Tunisia, and everyone has to take a break.

But even so, Carlo still received good news.

"What, the practical AC system has been successfully developed?"

Facing Carlo's look of surprise, the captain of the guard Felimich, who was in charge of delivering the news, was a little surprised but nodded anyway, although he didn't know that the research and development of this alternating current was worthy of the king's attention.

"Prepare the car, let's go to Marino immediately."

Carlo did not have time to explain to his chief guard the importance of the utility of alternating current to Italy, for his heart had already flown to Marino, and he was a little impatient to see the practical alternating current.

When Carlo arrived at the Marino Electric Experimental Center, he immediately saw Tesla and Argos waiting for him at the gate, and it seemed that they had already figured out their temperament as a king, and knew that they would definitely appear at this time.

"Carlo, we made it."

Tesla, who was in high spirits, rarely showed off.

"Yes, we have changed times."

I didn't expect Carlo to be more flamboyant than him.

Well, the two flamboyant young men hugged each other even more after getting closer.

"Take me to see it, now I can't wait to see the practical AC."

Seeing Carlo's impatient expression, it made Tesla very satisfied.

"Your Majesty, please come to me."

When the group arrived at the laboratory, they saw Tesla pointing to a circle of connected instruments. "Your Majesty, this is the practical alternating current system I developed."

"Can you tell me about it?"

Looking at the various objects in front of him, Carlo plans to listen to Tesla's introduction.

"Glad to serve, Your Majesty."

"As long as you do electric power research, you know the difference between alternating current and direct current, in which direct current is stable but the transmission distance will cause a huge waste, so the transmission distance is very limited."

Of course, Carlo knew this, otherwise Edison, who was in the United States, would build a power station every 1 kilometer.

Although AC has a long transmission distance and low loss, the size and direction of its fluctuating current change, so that the current motor can not be used at all.

In fact, when the current changes direction, the magnetic field then changes its strength and direction, so it is inevitable that the motor will stop rotating.

And Tesla, faced with this thorny problem, has come up with a new solution. "Your Majesty, please see, this is an alternating current motor designed by me."

He pointed to a motor that looked similar to a DC motor and spoke. "I added an electromagnet winding to the motor that generates a stable magnetic field, which allows the motor to have a magnetic field of constant strength. This allows the alternating current to be used properly in the motor. ”

Obviously, Tesla also knows where the current big electricity users are, although at present, in the lighting, let the people feel the use of electricity, but the big electricity users have always been factories.

Obviously, Tesla also knows that only by taking down the factory can the AC system be used on a large scale.

Of course, in addition to this alternating current motor, he has similar alternating current equipment here to later generations, but because it is a laboratory, there is still a lack of equipment to increase and lower voltage.

Of course, transformers are already available now, and the Frenchman Lucien Gourard and the Englishman John Gibbs presented the device to the public at an exposition in London two years ago.

Of course, Tesla has not only developed alternating current motors in the past three years, but also because of its fluctuating characteristics, Tesla has specially developed a lot of gadgets to subdue it because of its undulating characteristics.

Tesla will only briefly introduce these gadgets, but Carlo can still see his complacent.

After listening to his introduction, Carlo looked at the master of electric power research in front of him. "Nikolai, what do you think about high-power AC motors?"

When it comes to his own profession, Tesla said directly. "It's not complicated. In fact, the design of high-power AC motors is not complicated, and I don't think there are many problems at this point. ”

"And what about large, high-power, high-frequency alternating current motors?"

Carlo's inquiry made Tesla stand still, and the question was not so easy to answer.

Carlo looked at Tesla in front of him, not anxious at all, this is famous for developing motors in this area, and it shouldn't stump him.

Don't blame Carlo for squeezing Tesla so quickly, although he can wait, but Italian industry can't afford to wait. The current pace of industrial development in Italy is not satisfactory to him, and if he wants to develop by leaps and bounds, he can only embrace electrification.

The prerequisite for electrification is the availability of large quantities of cheap electricity, and this is where large, high-power and high-frequency AC motors are a priority. This is because this can significantly reduce electricity bills and allow more factories to use motors.

Carlo had his own considerations on this point, and he immediately spoke to Tesla. "I hope that the research will be divided into two main categories, one is ordinary industrial motors, and the other is practical high-power and high-efficiency generators."

"It's not too much, but what more do you want from a generator?"

"Naturally, the higher the better, but I also know that this is impossible, so let's take a 5000 horsepower, 2.2KV power generator as the standard."

Of course, Carlo doesn't want the horses to run and not give them grazing, so he continued. "I will invest 20 million lira to build a company specializing in the production of this kind of motor, I have a name in mind, it will be called Westinghouse Electric Company, Tesla, your contribution can be seen by everyone, so you will have 10% of the company's revenue."

In the face of Carlo's generosity, how could Tesla refuse, but I felt a little embarrassed to say yes like this.

Just as Tesla was squirming, Carlo immediately made a decision for him. "That's how we decided, who made us friends, I can't let my friends suffer."

He won't let this person live the rest of his life as poor as in his previous life, but he will definitely not let him wander at will. You must know that this wave is also incomparable, such a sinkhole of wireless power transmission, otherwise let alone Italy, even if the British government comes, it is not enough to see.

Later, after talking with Tesla for a while, Carlo invited him to lunch, and of course, he did not pull down the rest of the laboratory, and gave him enough rewards.

Under the grateful eyes of the staff of the Marino Experimental Center, Carlo left satisfied.
