At this moment, almost all the guests present had already understood what the big move of the Kyushu Academy of Sciences was.

- Thermal power station!

Large alternating current power plant!

The commercial value of this can be seen clearly by anyone who can appear here as a guest.

To understand the business value, we must first understand today's national electricity market. All of them are DC power supply, mainly dry batteries.

Ordinary people rarely use electric lights in their homes, and they all use candles. Only a more modest person will use electric lamps, and the energy consumption of electric lamps is the use of dry batteries. The consumption of dry batteries in each region is extremely enormous.

Some developed cities have street lights, and all street lights use dry batteries.

The general price of a dry battery is about 200 coins. It can make a 40 watt bulb last for 7 days.

Therefore, the battery market in Kyushu as a whole is extremely prosperous, and it is almost in the form of an exclusive monopoly. The production data of dry batteries, as well as the principle data of direct current, are all controlled by the National Academy of Sciences, and are fully controlled by the inventor and the father of direct current. Exclusive monopoly.

And when the Institute of Electromagnetism proposed alternating current, everyone felt that something was wrong. Because the alternating current he proposed no longer needs batteries, only the power grid, which can allow the current to enter thousands of households.

More power, more amazing transmission power. Everyone can't help but guess that if alternating current really works, then it is undoubtedly equivalent to 80% of the profits in the exclusive monopoly of the National Academy of Sciences.

People don't have to buy batteries anymore, and they don't need to be so time-consuming and laborious. Even if you use the same electricity, the price is the same. Instead, people will be more inclined to AC because it is automatic transmission and does not require you to install and remove the battery.

But the hearts of the guests were still only speculations, because it was too difficult to lay. In addition, the issue of cost is a big problem.

However, the advent of the electric motor made everyone aware of it. It seems that the era of changing the power of Kyushu is coming. The asynchronous AC motor with greater power needs more power AC, and the DC power cannot be carried at all.

At this time, everyone was already a little sure in their hearts.

And it wasn't until the steam turbine of the School of Mechanical Power came out that they were completely shocked......

The era of alternating current is coming soon.

As long as you are a businessman, you can see the benefits clearly. A thermal power station can generate energy for one day, and it can supply the entire Qingdao County for a week.

What is this concept? This is a profit that will monopolize the entire electricity market at an extremely frightening rate.

This steam turbine is coal-burning. Even if you burn it for one day, how much coal can you burn?

However, the electricity it provides radiates to the entire Qingdao County, and it can be used for a week. The difference between cost and profit is so great.

Most of the results are linked to alternating current.

The Kyushu Academy of Sciences is a bit big this time, is this Li Zhen's big move?

Li Zhen saw that Qin Enze had gradually finished explaining the steam turbine, and walked back to the auditorium with a smile behind his back, the corners of his mouth outlined a trace of arc, calm and confident.

"When alternating current radiated over a large area throughout Kyushu, the industrial age naturally arrived. Surprisingly, there was already a steam forging machine in Nanzhou. Using the principle of steam engine, a large number of steam machines were manufactured to replace labor. Preliminary machine tools? Some businessmen have already begun to use the steam engine to promote the industrial age. And when the alternating current is laid, when the asynchronous motor, synchronous motor, and three-phase motor are all mature, Kyushu will have a new look. ”

With a mutter, there was a raging fire burning in Li Zhen's eyes, which was the growth of ambition.

"Three years at most. Kyushu will be twenty years ahead of the whole world. ”

“……”

And then the guests who returned to the auditorium also began to ponder their own thoughts, the huge benefits hidden in it, the almost terrifying profits, made everyone crazy.

"Ladies and gentlemen, you must have seen my classmate's steam turbine, oh, the steam turbine. My name is Liu Jinghong, I am a native of Laoshan County, and I am also the dean of the Institute of Aeronautics of the Department of Physics of the Kyushu Academy of Sciences. ”

'Wow-'

The scene exploded again, and everyone exclaimed and raised their brows, Aviation Research Institute. This Kyushu Academy of Sciences, the most mysterious, the most awesome discipline.

Wang Zhongshu sighed and said with a wry smile: "Lin Xiufeng, a physics master who was transferred from our school by the imperial court, is now also the vice president of the Aviation Research Institute. The rebellion was complete. ”

Xu Shenxue also smiled bitterly and said: "The teachers from our school have also become students here. Where to go to reason, this is so magical. ”

"Haha, it's not a student. They are a little irregular here, they are called by classmates, students, and colleagues. I don't understand. ”

“……”

Liu Jinghong smiled, and his confident momentum was unobstructed: "I believe everyone knows that our Aviation Research Institute is dealing with astronautics. I won't mention the paraglider, it was just a manual experiment of ours, and I didn't expect it to become popular. Hehehe. ”

As soon as these words came out, the physics students in the background scolded one after another: "This thief is very shameless." ”

"Obviously, the paraglider that everyone researched together, his mouth moved, and this became a small experiment of their aviation research institute."

"The most shameless is Liu Jinghong."

“……”

On the stage, Liu Jinghong continued: "What is paragliding? What about jumping from a height? If humans want to truly touch the blue sky, they still need to rise from the ground and be able to enter the blue sky autonomously. There is no longer any need to rely on mountain cliffs. ”

Feng Naien raised his eyebrows: "Could it be that in such a short period of time, the Kyushu Academy has really researched a flying machine in the true sense?" ”

Qian Mao squinted his eyes, a little excited: "I think so." ”

“……”

Liu Jinghong laughed: "Now the outside is ready." Please take a step. ”

Move again!

It seems that the finished product has appeared.

A thousand guests came out one after another, but Li Zhen was a little too lazy to move, so he didn't go out at all, just sat on his seat and dozed off.

When the crowd went outside. All the staff of the Aviation Research Institute, under the leadership of Lin Xiufeng, have already made preparations.

In the courtyard, there is a basket made of bamboo, which is four or five square in size, and there are sandbags and other things in the basket. The basket is connected by a dozen steel wires to a large piece of special fabric that covers the entire floor.

As Lin Xiufeng controlled a machine above the basket, the machinery continued to spew out raging flames, and the flames rushed into the special cloth, and the cloth soon began to swell. Then it slowly expanded into a huge ball and floated in the air.

Liu Jinghong smiled: "This is our latest achievement, hot air balloon. As you can see, a hot air balloon is a lighter-than-air aircraft, with a large balloon on the top half and a gondola on the bottom. The inside of the balloon heats the air, so that it has a lower density than the cold air outside, and acts as a buoyancy force to displace the whole; The gondola can carry both passengers and heat sources...... And the core of the whole hot air balloon is the alcohol blowtorch that Vice President Lin is operating. It is the primary tool that provides upward momentum to the hot air balloon. ”

“……”

Everyone was stunned to look at the big balloon that had floated up, and looked at Liu Jinghong and Lin Xiufeng standing in the hanging basket, looking at each other.

"This ......"

"So you can go to heaven?"

"It doesn't have wings, it doesn't have anything, so it can go to the sky?"

"That's fine, how did they come up with this."

"Look, the basket is floating!"

“……”

'Whew'

A blue dragon burst out of the blowtorch, and the inside of the balloon suddenly inflated again.

Liu Jinghong threw down a sandbag in the hanging basket and said with a smile: "This is a hot air balloon." ”

'Whew'

There was a sudden shock. The red, huge hot air balloon suddenly sped up, and with the two people under the hanging basket, it flew into the sky at high speed......

The people of the entire Laoshan County raised their heads at the same time.

I saw a hanging basket hanging under a large red balloon, and two people standing in the hanging basket overlooking below. The hot air balloon has huge words written on it - Kyushu Aviation Research Institute.

"They're really up to heaven."

"The real heavens."
