To build a solar power plant, you need to consider the way in which solar energy is converted into electricity, one is light power generation, and the other is thermal power generation.

Photovoltaic power generation, also known as photovoltaic power generation system, uses solar cells, storage batteries, controllers, inverters, AC distribution cabinets, solar tracking control systems, etc., to form a photovoltaic array.

The advantages are high reliability, long service life, no pollution to the environment, and each module can operate independently.

The disadvantage is that the power mediation is complex, it belongs to the plane light source, the density is small, affected by the weather, the regional distribution is different, and the maximum daily ground power generation is 1kw/square meter.

In addition, polysilicon is required to manufacture solar installations, and in the past, Huaxia needed to import it.

However, there has been a bit of a stalemate with the North American Technology Alliance recently, where in order to restrict the development of Huaxia Technology, a 30% tariff on polysilicon exports has been imposed, and material manufacturers will definitely not sell it.

Fortunately, Tiancheng has graphene, which is a bit more expensive, but combined with the newly refined perovskite in the scientific laboratory, it can increase the solar energy conversion rate of 5% of traditional crystalline silicon photovoltaic panels to 19%, and soon reach 25%. (27% after 20 years of parallel space-time)

Like wind power, this is Tiancheng's main power supply method in the future.

However, similar to the problem encountered by SG, the production capacity is insufficient, and it is necessary to wait for the return of the three electronic companies to divide the business to Longtian and Wanshi before it can be laid on a large scale.

In the plan, the canal CBD will build a 2,000-acre area, about 1.33 million square meters, a total of 1,500 installations, and an investment of about 1 billion yuan, covering the solar photovoltaic system of the canal's industrial buildings.

Due to the improved solar energy conversion rate of graphene photovoltaic materials, 1.5kW of electricity per square meter can be provided per day, totaling about 2 million kW, or 730 million kWh of electricity per year.

It can meet the demand for electricity in Canal CBD, Tiancheng Plaza, Financial Street, and Science and Technology Park.

It is expected to return on investment in three years and be profitable in the fourth year.

According to Ge Xiaotian's idea that Diao Min wants to harm me, the above will definitely not agree.

But unexpectedly, not only Weimian's electrolytic aluminum power plant was approved, but the Longtian solar project also received a three-year high-tech subsidy of 300 million yuan......

After that, Ge Xiaotian looked at the total electricity consumption in Huaxia, and found that it was 1.8 trillion yuan, and 90% of the thermal power plants were in a state of loss......

Compared to this, what is 730 million electricity?

However, the purpose of building power plants is to recharge town centers, and now that it takes time for solar power to be generated, another way of generating electricity needs to be considered as it is imminent.

That is, solar energy, thermal power generation.

There are many types of thermal power generation.

The earliest trough power generation is the use of single-shaft trough solar tracking lighting panels, the use of parabolic reflectors to heat the internal heat conduction liquid, drive the steam turbine generator to generate electricity, roughly similar to the old solar water heater.

Later, people invented butterfly power generation and tower power generation, and most of the principles used were steam generators to drive turbine generators to produce electricity.

Later, people turned their attention to the oldest of the sun pools.

It is a kind of solar coking project that adds salt to the water in the pool, so that the convection is inhibited, can double as a solar collector and heat storage, and is used to drive a steam turbine to generate electricity, with simple structure and convenient operation, which is conducive to large-scale development, and can be used for hot water, heating, air conditioning system, as well as grain drying, papermaking, salt making and seawater desalination and other projects, and can even be used in remote rural areas, which is very convenient to use.

However, due to the principle of heat storage, solar pools can only be built in areas with poor soil and no mineral deposits, so as to avoid water pollution and heat loss.

However, it does not require much light intensity, and with the improvement of technology, it can still work even at night and in rainy and snowy days.

The last is Stirling power generation.

The reflection system composed of many mirrors is used to focus on a certain point, and the heat source of 600 degrees to 2000 degrees is directed close to the Stirling engine to drive the generator to generate electricity, with high heat energy conversion rate, low noise, and very environmentally friendly, but the technology patent is in North America......

After thinking about it again, Ge Xiaotian decided to take advantage of the infrastructure to develop the sun pool.

The project is experimental in nature.

Wait until the town center is charged to a safe state of 5% of the total power, and then tear it down and build a wind power station or photovoltaic solar power.

Why experiment?

Since the Sun Pool is suitable for barren areas, Ge Xiaotian intends to use it to make money in the Great Northwest and Africa.

After all, only with electricity can we engage in production and infrastructure.

And after a few days of construction, Sun Pool No. 1 has been completed and put into operation.

Relying on the Grand Canal, which is being managed, dig a tributary river, break the flow and build embankments, and besiege the small lake.

The lake water is then stratified from top to bottom: low-concentration brine, non-troposphere, high-concentration hot brine.

A large steam turbine is placed behind the embankment, and two underground tunnels are dug to connect the high concentration of hot brine to the bottom of the small lake, one is the outlet and the other is the water inlet, and the heat exchange evaporator is used to push the large steam turbine at the top to generate electricity.

The principle is roughly equivalent to making an old-fashioned solar water heater into an infrastructure project, with almost no technical content, mainly in the monitoring of the lake temperature and the control of water flow.

If there is a Dead Sea nearby, Ge Xiaotian can rely on the system to build it into the world's largest solar pool power plant......

Because it is an experiment, the scale of Sun Pool No. 1 is not large, covering an area of 100 acres, only a 10MW (10,000 kilowatts) unit is used, 10,000 kilowatt-hours of electricity per hour, the steamer is similar to a locomotive, and the whole building is like a small villa.

Ge Xiaotian walked around the embankment and said to the project leader that he communicated with the project leader until the evening.

Finally, think about it, "You should go to Africa too!"

“？？？”

Although Tiancheng still has a long way to go from an expedition overseas, if you want to make a lot of money from above, or take over projects from above, you have to prepare in advance.

Relying on the funds from the sale of slippers and electronic products, the intelligence department was formed first, and then a power plant was built, a factory was built, materials were collected, and when the main force arrived, everything was OK, and the construction could start on the spot, which could also reflect the speed of Tiancheng's construction.

The key is that during this period, you can make gold and develop the great northwest......

Just the security aspect......

"I'll discuss with Horton about sending you a Tianwei from North America, as for equipment or something, I'll go to Ice Bear in a while, and talk to Mr. Governor by the way, and see if I can get you a batch of gala and rumble...... However, if we are equipped with armor and swords, bows and horses, we can almost protect ourselves, so there is no need to play so advanced. Anyway, after the past, don't go around fighting and just guard the factory......"

"Do I dare?"

"By the way, take the idle No. 2 town center, disguise it as a sedan chair, charter a plane over, go to the entire base first, and if you really encounter a long-sighted one, you will push out the Zhuge crossbow and artillery cluster, this is your main business. ”

"If you don't say it, I'll forget ......"

“......”

Did God forget that if I had been thinking about this all day, I would still be alive?

Ge Xiaotian contacted Gao Song.

"Have you packed up?"

"Nope!"

"Then I'll shoot Tianwei and take you to the airport!"

“......”

Then Ge Xiaotian contacted North American Horton, first replenished 1,000 novices to the other party, and then transferred 1,000 Tianwei from North America who had seen blood and had been promoted to lv2.

There are more people who went to Africa this time, and they can be regarded as Tiancheng's old team in African construction companies.

As for who will take the lead......

Let's take a look at Takamatsu's performance.

An hour later.

The offshore company sent an invitation letter, and Ge Xiaotian directly approached the young leader.

I never thought about it......

"Where are you going?"
