Datang: I was exposed by Princess Changle

In another two days, as long as there are no flaws after the inspection, it can be officially put into operation.

Now all the poles have been erected, and the wires have also been connected to the house.

In Chang'an City, most of the rich and powerful's homes have already been wired.

And also installed light bulbs and switches.

Of course, these all cost money.

Lin Xuan's setting is very simple.

Light bulbs, wires, and switches cost at least [-] yuan to enter the house!

The reason is actually very simple. In order to do this well, Lin Xuan didn't know how much money he poured into it.

If it is said that the cost is not recovered, wouldn't it be a loss?

It's not like he's doing charity work.

Lin Xuan took Li Shimin and Changsun Wuji and they had invested a lot of money, so they had to find a way to recover the cost.

Of course, if enough light bulbs are installed, the future cost will be even greater!

In addition to these expenses, there is also a monthly electricity bill.

It costs at least ten dollars per kilowatt-hour of electricity!

The greater the number of bulbs, the greater the increased cost.

There must be only one light bulb in a normal farmer's house, and it costs [-] yuan per kilowatt-hour of electricity, which they can afford now.

Because it is an early stage, Lin Xuan's asking price is so high.

Just hoping to recover the cost.

After it is probably popularized, Datang will invest in the addition of telephone poles.

And the common people will actually spend much less in the future to turn on the light bulbs by pulling the wires.

The money that should be spent must be spent, as for the others, it is easy to say.

In fact, if you do the math, you can see that the monthly cost of lighting candles and soybean oil is not cheap.

Now if they switch to light bulbs, they can save at least half of the money!

Lin Xuan yawned, and was also a little sleepy at this moment.

He has been busy dealing with these matters these days, and powering on is considered a major event.

All kinds of factors have to be considered, so Lin Xuan is also very concerned.

The output power is different from the input power, and power loss and the like have to be considered.

Therefore, everything must be handled properly, and it must be foolproof.

Fortunately, it's all done now.

Lin Xuan looked calm and walked forward slowly.

Looking at the light bulbs installed in the mansion, he also showed a smile.

Chapter 292 Power On!

He knows that he has more things on hand now.

Electric generators, steam engines, internal combustion engines...

But these can all be prepared slowly.

The generator is ready, and the steam engine is almost done now.

As for the internal combustion engine, there is no clue yet.

Lin Xuan has the relevant drawings here, but there is one thing that the current manufacturing process cannot meet the requirements for manufacturing internal combustion engines at all.

Therefore, he can only choose to develop slowly.

Because the resources and actual conditions they currently have are completely insufficient, and there is no way to meet the requirements.

As time goes by, the sun is gradually setting today.

The entire Lantian County fell into silence.

Although it is said that there is no curfew and there is a night market, in fact, there are not many people coming and going at night.

With Lin Xuan's continuous and rapid development, there is still a problem.

That is, the people of Tang Dynasty still adhere to their original living habits.

Work at sunrise, and rest at sunset.

They are used to this kind of life, and it is deeply ingrained.

Standing on the attic of his home, Lin Xuan looked at the installed telephone poles, with a smile on his lips.

Electricity poles, street lamps, high voltage wires. . . . . .

These are all slowly built by him step by step.

Without any exaggeration, in order to build these things, the difficulty can be said to be quite high.

Lin Xuan has been laying out the layout for a year and a half, and now he has just completed the laying of Lantian County and Chang'an City.

Moreover, it is not said that everything has been paved.

Only a few main lines can be guaranteed, such as Ditang University and houses on various main roads.

In the future, a power bureau will be arranged in a unified manner, and he will also select suitable people to take charge of it at that time.

They are responsible for the domestic power structure and output.

The current situation is actually not bad, and overall the preparations are very good.

Of course, this is just the beginning.

Seeing that the time was almost up, Lin Xuan raised his hand and snapped his fingers.
