It's incredible that the tail project also has a motorcycle, which stems from the plot of Juchen having a battery car, just like a knight has feelings for his horse, Juchen still has a lot of feelings for the battery car, after all, he has spent a lot of good time with his youth.

Soon, Juchen personally rejected the tail design scheme, because the motorcycle can better hide the photovoltaic panels - make him into a roof, fly directly from the wind shield and fly backwards, usually folded into an awning/rain shelter, and when you need to charge or travel long distances with zero power consumption, you can open the folding to get a power comparable to that of an ordinary charger.

It's impossible to run, but a speed of 40 kilometers per hour can still be guaranteed. Because there are not many photovoltaic panels needed, motorcycles don't need to have a "bridge" like a car at all, and it looks much more beautiful.

Of course, thin-film photovoltaic panels are very expensive, and few customers can afford them, and a tail alone costs tens of thousands.

This cattail project is a real flashy in a flashy one.

After estimating the price, knowing that the sales volume could not be much, Juchen needed to relax for a while, and he really went to the Middle East desert country.

The country of tyrants is building super skyscrapers in the metropolis, which makes people sigh that whether you like it or not, this skyscraper has changed the skyline of the earth anyway.

The prince said, "We have cheap oil here, but fresh water is not cheap, you know." ”

Juchen: "But I've heard that Israel's desalination technology is very powerful, and it can produce almost the same cost as a waterworks." ”

Prince: "We don't like that country, and we certainly won't use their technology." ”

Ju Chen: "Well, that Singaporean one seems to be good. ”

Prince: "Yes, we use the Singaporean one, but the cost is still high." ”

Juchen looked at the giant oil tanker that was leaving the port in the distance and said, "I have another question, if you use an oil tanker to transport fresh water, what will it cost?"

The prince laughed: "I said that fresh water is not cheap, but I didn't say that it is really more expensive than oil, and the cost must not be worth it." ”

Juchen checked the information, and the oil tanker can basically transport 100,000 tons of goods, while the freshwater treatment plant can produce 100,000 tons of fresh water, which is relatively large.

The cost is calculated at $0.5 a tonne, and the cost of 100,000 tons of freshwater desalination is $50,000. The price of crude oil is $350 a ton, which is not an order of magnitude, no wonder I have not heard of ships transporting fresh water.

Transporting a shipload of fresh water can make a profit of 5 to 100,000 yuan (it will definitely be expensive where there is no desalination), and the question is how to use a cheaper logistics system.

Of course, you can't use oil tankers, it's too expensive. Juchen also likes to use a subversive way of thinking, how to subvert the means of transportation? There is a thing called the use of seawater pressure itself, transporting fresh water is similar to the pressure of seawater, at least there is no significant difference, this is where it can be used.

Therefore, plastic film can be used for containers. The cost of plastic film is a world of difference compared to steel.

It is said that the Google balloon project uses special material technology, and the toughness of the film manufactured is much higher than that of similar products in the past, which is the core competitiveness of Google balloons.

Juchen doesn't need to know the cost of specific plastic film, think about the plastic bags used in express delivery and takeaway all over the mountains to know that the cost is extremely low. Plastic film is made into cylinders the size of train cars, which are closed to allow enough air for the train wagons in the sea to float on the water.

Each train wagon also needs "fins" to stabilize the carriage, and then a tug can be used to tow a "water dragon" away, and it is expected that a small tug can carry a load capacity comparable to that of a 100,000-ton oil tanker, and the cost of transportation is reduced to the cost of the main tugboat.

The reason why oil tankers cannot use this solution is because it is possible to pollute the environment, and fresh water is not a problem at all, and the most serious thing is that the owner of the ship will suffer from the egg pain after the leak.

In order to take advantage of the pressure of the seawater, most of the main part is below the water surface, and in order to prevent collisions, it is necessary to use obvious water surface markings, which is where the "fishtail" project comes into play, and above the plastic film water tank, several photovoltaic panels can float to provide abundant power to the tugboat.

In fact, the speed of giant oil tankers is often about 30 kilometers, Juchen feels that this power is still relatively easy to achieve, go back and check the information, the power of oil tankers can reach 30,000 horsepower, large tugboats 20,000, but due to the innovative plastic film to remove most of the weight, such as super large oil tankers, the weight can reach 40,000 tons, so Juchen's tug horsepower can be 10,000.

10,000 horsepower, like the horsepower of 100 cars, is not inconceivable to deploy a PV array of this level at a length of 300 meters.

This is not a problem during the day when the sun is abundant, and it can even drive with zero power consumption, but what about at night? What if the weather is bad?

Storing energy for a 10,000-horsepower generator on a battery must be expensive, and even the tugboat's cramped hull has nowhere to put it, which is the biggest engineering challenge.

It seems that it is still necessary to make a fuss about the material, because water can store heat, plastic film can store heat if it can keep warm, and hot water can generate electricity at night to drive tugboats.

Photovoltaic power generation has a lot of infrared single photon energy is not enough for the electrons to produce energy level jumps, so they cannot be used to generate electricity, but they also have energy, which is mainly wasted in the form of thermal energy.

At present, the mature geothermal power generation system basically requires a temperature of more than 150 degrees, and the solar thermal power station is to melt the salt, which can generate electricity efficiently, Juchen estimates that the hot water in the plastic film can be heated to close to 100 degrees at most, and the temperature is still much worse than these temperatures, unless through some low boiling point working fluid, such as isobutane, so that he produces steam into the steam turbine to work.

Despite this, the energy at night is still much lower than during the day, and Ju Chen has been fully prepared for this, which is the shortcoming of his entire plan.

This process is very complicated, and his and the prince's English may not be enough, so they can only make a PPT and then introduce it to the prince, after all, they have spent 100 million US dollars to buy shares, and if they don't show a little sincerity, I'm sorry for them.

His Royal Highness the Prince was deeply shocked by the Water Dragon Project, and really didn't expect Professor Ju to be able to bring innovation to such a brilliant point, of course, the shortcomings are obvious, and the probability of failure is high, but this innovation ability has made the prince feel that the $100 million is worth spent.

Not every port has a desalination plant nearby, so this cheap freshwater transport option may compensate for some of the freshwater crises in arid regions.

Juchen's Water Dragon Concept Ship was presented to the world at a press conference to attract elite engineers to his project.

Humanity seems to have forgotten about his ill-gotten gains, captivated by his constant stream of big news, which many tech leaders say is "because of Tristine."

At this time, no one seems to laugh at the Middle East tyrants for being stupid and having a lot of money, and it seems that there are special effects in cheap transportation? At the time of the special effects production, Juchen has already found someone to calculate the cost, because the plastic film water tank is incredibly cheap, and it is also profitable to transport fresh water from 1000 kilometers away, which is almost comparable to the cost of seawater desalination, and there is no need to build a factory, there is no loss of various desalination plants, and the comprehensive cost is lower.

Using 0.1 tons of water per person per day is a good level, according to this figure, the ultimate 100,000-ton water carrier can meet the needs of 1 million people, even if you use solar energy to travel 8 hours a day, 1000 kilometers only takes 4 days.

Four water dragons can meet the freshwater use of 1 million people in large cities.

The technology may even be applied in China, which is not a water-scarce country, but when drought years come, mayors of major coastal cities ask if desalination projects are feasible.

Seawater desalination is no problem, Singapore and Israel are very advanced in technology, but the whole city needs to build special pipelines, this is not a simple project, and when the project is about to start, the drought has passed, so, until now, there are few big cities in China that use desalinated seawater.

Now, the water dragon project offers new possibilities.
