In the laboratory of the Institute of Mechanical and Electrical Engineering, almost everyone was staring at a small light bulb.

Half an hour passed, and the small light bulb was still on!

Suddenly, the light in the laboratory became noticeably dark.

The small light bulb was not turned off, but the big light bulb that looked like a searchlight was turned off.

There was no surprise on everyone's faces. The big light bulb had been on for almost an hour, and the air inside the light bulb was not pulled out, so it was normal to extinguish it.

Taichang looked at the extinguished big light bulb, then looked at the small light bulb that was still on, and a trace of thought appeared in his eyes.

Now it seems that just by evacuating the air in the big light bulb, it will be fine to light it for twelve hours.

It only took five or six hours a night.

In other words, there is no problem with the big light bulb being on all night.

This can be put into practice and can be installed in the palace. At most, it can be replaced with a batch of light bulbs in two days.

Anyway, it won't waste much money. This thing is just a big investment in the early stage, and the fused filament can be recycled in the later stage.

The problem now is that it is inconvenient to change the light bulb, because the wire inside the light bulb is directly connected to the generator.

Taichang thought for a while, then pointed to the outside of the big light bulb and gestured: "Secretly, you have to cut off this thread and make a connector so that it is convenient to change the light bulb.

Keep the wire at this end of the light bulb as short as possible, which can also save costs.

Or, you can just leave the thread inside and not stick it out, and leave two copper or aluminum sheets outside as joints."

Fang Yizhi did not consider this issue.

Because he was still experimenting, he didn't even think that the light bulb would be put into use so quickly.

However, he has developed many ways to connect the connector. The easiest one is the plug and socket that Taichang told him at the beginning.

He just thought for a while and then the celebrity took a set of plugs and sockets, then cut two wires about a foot long into the plug, and a golden filament was connected to the other end.

Immediately afterwards, he used Professor Chen Yunpei's method to wrap a rubber bump like a plug and stuffed it into the glass light bulb together with the needle that pumps the air.

Then he ordered people to turn on the air-pumping device.

The light bulb is not big at all, so the vacuum is naturally very fast.

After a while, the light bulb was vacuumed.

He then applied resin glue around the needle tube like Chen Yunpei, then quickly pulled out the needle tube and pinched the resin glue in.

Immediately afterwards, he said impatiently: "Hurry, turn on the socket."

This is simple, his disciples put the socket and generator in just a few seconds.

He picked up the plug and plugged it into the socket. The light bulb, which was as bright as a little sun, lit up again.

This is a good method, so I will do it in the future!

He said excitedly: "Your Majesty, how about it? Is this kind of approach good?"

Uh, what do you mean by this?

You're still a bit of a waste of materials.

However, it is already very good to be able to do this at this stage.

Taichang nodded slightly and said, "Well, it's not bad. Use this method to replace the light bulb first. You can try other cost-saving methods slowly.

Next, the light can be put into trial use. You can order your disciples to install generators in the palace, and then take the Jinyiwei and the eunuch to wiring, and connect all rooms in the palace with such lights.

By the way, this kind of headlight is just a temporary measure to shoot silver foil. You can stick the silver foil onto a thick wooden board and then hang circles of glass beads or square or diamond-shaped glass blocks under the wooden board.

In this way, this kind of electric light looks high-end, elegant, and high-end, and it is no problem to sell one hundred taels of silver."

It can still be done like this!

Fang Yizhi couldn't help but nodded excitedly and said, "I understand."

Taichang then taught: "You can also stick silver foil into the lampshade so that the light can shine far away.

Think about it, if there are some searchlights on the dock or on the boat, will the ship be able to sail at night?

With this kind of searchlight, is it okay to maintain ship distances, or to dock at the dock in ports?

You can first install searchlights on the Feilong Battleship and try it at the Wubei City Pier."

Fang Yizhi nodded without hesitation and said, "Okay, Your Majesty, I will take someone to try tonight."

It seems almost done.

Taichang thought about it again and then explained: "You will find two more workshops, one for producing light bulbs and the other for producing wires.

Once this electric light is promoted, the required bulbs and wires are huge. The output of light bulbs should reach at least 100,000 per month, and the output of wires should reach at least 1 million per month."

My God, so many!

Fang Yizhi was stunned for a moment, then pulled Shen Yunpei and muttered.

The result they muttered was that the wire production was not reaching one million feet per month.

Fang Yizhi said helplessly: "Your Majesty, there is no problem with making 100,000 light bulbs a month.

The Ministry of Industry already has a factory specializing in glass production. As long as the output is increased, there will definitely be no problem to make 100,000 glass bulbs every month.

The problem is that the goal of producing one million feet per month is difficult to achieve.

Because at this moment, almost all the plastics made by Longxing were used for Weichen. Undersea cables alone could consume plastics. One million wires were produced a month, and plastic was not enough!”

Is plastic enough?

Taichang couldn't help but say to Shen Yunpei on the side: "Longxing, what are you busy with during this period?"

Shen Yunpei hurriedly bowed: "Your Majesty, the plastic separation technology used to make the insulating layer has been almost done.

WeChin is studying the application of gasoline and diesel. After all, we have already stored a lot of gasoline and diesel. If we don’t use it, it will take up too much space there.

Now Weichen has already thought of some ways to use it.

For example, to use it for fire.

What Weichen thought of was to constantly press air into a can, spray the gasoline and diesel mixed in it, and then ignite it.

If this kind of fire-breathing thing is used to burn a boat, it is not too fierce. Just spray it on the boat for a while and then lit it."

My God, this guy even thought of the flamethrower!

very good.

Taichang nodded slightly and said, "This flamethrower is indeed useful, especially against small arson ships of the enemy.

As long as the warships are equipped with a few such flamethrowers, the enemy's small arson ships will be lit directly once they get close, burning their own ships.

Also, you can find a way to develop a flamethrower that can run on your back by a single person.

As for how to pressurize the fuel tank, it is actually very simple. You know the steam piston. That thing can actually be used to boost the pressure. As long as the connecting rod can be connected to a handle, and you can continuously shake it up and down with your hands to boost the fuel tank.

Of course, this thing doesn’t have to be as thick as a steam piston, and it doesn’t matter if it’s thinner. If it’s longer, the pressurization effect will be more obvious.”

When Chen Yunpei heard this, he couldn't help but bow excitedly and said, "I understand."

Well, this thing isn't the most important thing.

Immediately afterwards, Taichang asked again: "How many barrels of oil can we produce a day now?"

Chen Yunpei still doesn’t understand why oil is calculated using barrels.

However, Taichang stipulated from the beginning that oil was calculated using a barrel of half a meter high and about two feet in size, and this one was used later.

Chen Yunpei heard this and estimated: "Now we can collect about five or six thousand barrels of oil a day."

That's the point?

Too few!

Taichang shook his head slightly and said, "No, this amount is too small.

Mizhi requires a lot of plastic to make wires here. How much plastic can be separated by five or six thousand barrels a day?

Also, we have sold candles and kerosene lamps to the continent now, and kerosene lamps and candles have also begun to be used in the Americas. The demand for candles and kerosene in these two places will definitely increase sharply.

In Africa, the demand for kerosene and candles will also increase rapidly in the future.

It is not too much to be enough to be only five or six thousand barrels a day, at least five or six hundred thousand barrels a day.”

Chen Yunpei was stunned when he heard this.

Five or six hundred thousand barrels a day!

He was stunned for a while, then he said carefully: "Your Majesty, the Shaanxi Chengxuan Department of Political Science and Engineering does not seem to have so much oil. It will take 50,000 barrels per day to burn the oil there.

Moreover, we can't recruit so many people to mine oil at this moment."

Well, the important strategic material of oil is indeed ignored.

Taichang thought about it carefully and then asked, "How did the oil be mined now?"

Chen Yunpei said without hesitation: "Oil mining is relatively simple. It is just digging a large hole like a water well, then installing a large water truck, turning the oil inside, first filtering the impurities through the filter, and then flowing into a large funnel with a valve.
