Red Sea, port of Hongku.

As the first area in North Africa to be developed by Homo sapiens, there are very few traces of North Africa here, and the modern city, with a permanent population of more than 840,000 and a large number of tourists, makes it very lively.

Of course, the excitement inside Homo sapiens is not the kind of crowding.

Homo sapiens' entertainment division has a subsidiary called "Tourism Data Network", which is responsible for one task, that is, to evaluate the tourism index of each region.

The so-called tourism index is a reference index formulated according to the scale of a city's infrastructure, waiters, and tourism facilities.

For example, the port of Hongku, where Simmons and Sophia's family came over, has a local tourism index of 2.6.

2.6 means that the local area can only receive a maximum of 26,000 foreign tourists per day, because there are a total of 19,467 rooms in the exclusive guest house + staff hotel + foreign guest hotel.

As for why not expand the hotel, the reason is that there is no need for that, and it would be a waste of resources to do so.

Homo sapiens' approach is not to expand the scale of the hotel, but to rationalize the flow of tourists to avoid tourists from gathering in a few cities.

As soon as Simmons and the others got off the plane, they felt a wave of heat rushing towards them.

He hadn't been to Hongku Harbor before, but since it was the property of Homo sapiens, many things were the same.

On the airport side, there is a car rental station.

"Sophia, Mom and Dad, you wait for me here, I'll drive over."

"Hmm."

Simmons walked into the rental car station, and when the attendant saw him walk in, he stepped forward to say hello: "Hello, what car do you need?" ”

Simmons thought he would need to take four people, so he asked, "An SUV." ”

"No problem, here's the list." The attendant projects a large number of SUV-type models and rental car fee schedules.

After watching for more than ten seconds, Simmons asked a little strangely, "Huh?" Why are there no gas cars? ”

"Gas vehicles have been eliminated, and now they all use electric vehicles." The waiter explained with a smile.

"Why? Electric car charging is too troublesome, or gas car is more suitable. ”

The waiter continued: "Don't worry! Instead of using a plug-in electric vehicle, we are using a liquid-filled electric vehicle. ”

"Liquid-filled? Charge the solution? Simmons asked, somewhat uncertain.

"Yes, the Suyinshi branch and the Numidian branch are the first batch of pilots."

"Thanks, just this Obsidian 5!"

"Okay, wait a minute." The staff quickly enters the instructions on the operation panel.

After a while, the underground elevator went up, and an Obsidian 5SUV made by Jewel Automobile Company appeared in front of Simmons.

"You can activate it by swiping your card directly."

"Thanks, I understand." Simmons took out the employee card and swiped it on the door handle, and suddenly the car's headlights flashed slightly.

When he got into the car, he didn't notice any major changes, and replaced the gas meter on the dashboard with a fuel gauge.

There are many reasons why Homo sapiens has eliminated gas vehicles.

On the one hand, because Homo sapiens is completely decoupled from the free world, there is naturally no need to comply with international patent law.

On the other hand, it is to save energy and reduce the waste of gold resources.

After all, using the mode of micro gas turbine + lead-acid battery, the thermal efficiency is only about 50% at most.

If every micro-gas turbine generator were to be converted to a gold-based thermoelectric system, the thermal efficiency could indeed be increased to 97 percent.

The problem is that the price of doing so is to replace the gold-based thermoelectric module with every car, which requires a huge amount of gold.

Therefore, it is better to switch directly to a pure electric vehicle and use the high thermal efficiency of the power station to generate electricity for charging.

However, pure electric vehicles also have disadvantages, that is, battery life, battery energy density, battery charging speed, and battery safety.

In addition, the current lithium battery needs to use a large amount of lithium, and there are some rare earth materials, which is not conducive to large-scale application.

After research by the Science Division, they came up with a completely new material: fullerene-nano sodium-aluminum material.

This thing has several advantages.

First, the fullerene-nano sodium aluminum solution with a concentration of 5.7% can store 0.7 kWh of electricity per liter.

Second, the stability is very good, and the charging process of fullerene-nano-sodium aluminum molecule is that two fullerene-nano sodium aluminum are combined; The discharge process involves irradiating infrared rays with a wavelength of 950 nanometers.

If it is not irradiated by infrared rays, fullerene-nano-sodium aluminum will not be discharged.

Third, the temperature adaptation range is relatively large, from 253 degrees Celsius to minus 106 degrees Celsius, which can work normally.

Fourth, the discharge is complete, and there will be no discharge to 20%, and it will not be able to continue to be released.

Fifth, the production cost is relatively low, and the service life can be as long as about 12.7 years.

With so many advantages, the advantages of liquid-filled electric vehicles are very obvious.

Moreover, the previous filling station can be transformed into a liquid-filling station, and there is no need to lay a large-area charging pile.

The advantage of filling liquid is that it is faster than plugging in, and it can be fully charged in a few minutes, without waiting for hours.

After all, today's plug-in electric vehicles, even if they use a 380-volt charging pile, fast charging takes half an hour, and if you use a 220-volt circuit at home, or a 110-volt circuit in North America, the charging speed is even more impressive.

There is no comparison of the speed of the two.

The energy density of fullerene-nano sodium-aluminum solution is 0.7 degrees per liter, and the specifications of the electrolyte reservoir are similar to those of fuel vehicles.

Typically 40 liters for mini cars, 60 liters for small cars, 90 liters for medium cars, and large and heavy vehicles can be set up as needed, and even an external fluid tank can be attached to increase the range.

The Obsidian 5 rented by Simmons has a 90-liter electrolyte reservoir that can store 63 kilowatt-hours of electricity.

In fact, some long-distance buses will add an auxiliary tank to double the power reserve.

Simmons drove to the door in an electric car.

"Sophia, this way!"

Sophia took her parents into the car.

After turning on the autopilot assistance mode, the car drove towards the Marina Hotel.

"Sophia, have you booked a room?"

"Booked, the double room here is cheaper than the single room."

"By the way, Sophia, there should be a yacht rental station here, right?"

Sophia took her mobile phone and searched: "Well, there are three yacht charter companies, do you want to rent a yacht?" ”

Father-in-law Aosta was a little worried: "Yacht? Don't spend any money, we just need to bask in the sun at the beach. ”

Sophia smiled and shook her head: "Dad, what do you want?" How much does it cost to rent a small yacht? Simmons has an income of more than 4,000 a month, and this kind of 10-seater yacht only costs 10 yuan a day. ”

"......" Aosta was shocked, even after experiencing the golden age of Europa, they did not have such a luxurious life.

Sophia diverted the topic: "The weather in Europa has been a little abnormal recently, why don't I find you a nursing home here?" In addition, my mother's diabetes also needs to be treated thoroughly, so I will make an appointment with the local hospital. ”

"We don't have insurance here, can we stay in a Homo Sapiens nursing home?" Aosta was a little incredulous.

Simmons interjected: "Yes, as long as you have children working in Homo sapiens, you can apply, the company does not require employees to pay insurance premiums, and we do not play this kind of financial game." ”

"That's good." Aosta can only sigh that the Homo sapiens company is rich and rich, and there is a advantage to take advantage of, who would refuse this kind of benefit.
