Great Power Technology: Domination Of The World Starts With Chips

Then, they came to the test bench.

Equipment to test the resistance of superconductors has long been in the laboratory.

Gu Ge found these devices and began to prepare for the test.

He held the niobium-titanium alloy cylinder in his hand as if it were a sacred object, first found an insulating tape, wrapped it several times, and only exposed the two ends. Through this method, the current loss will be avoided when the electricity is turned on later.

An ammeter was found later.

It is obviously not ideal to measure with an ohmmeter. The resistivity of a superconductor is about 10 to the minus eighteenth power ohm·m?/m. Such a low resistivity cannot be measured by just looking for an ohmmeter.

So the way is to increase the voltage, energize the circuit with a higher voltage, then measure the magnitude of the current, and then calculate the magnitude of the resistance according to the formula.

That is to say, treat this superconductor as a resistor and calculate it according to Ohm's law. Anyone who has studied high school physics will know it.

Therefore, a power supply capable of providing ultra-high voltage is also prepared next to it.

After all the circuits are connected, connect the test lead of the ammeter to the two ends of the room temperature superconductor, which is regarded as a parallel circuit.

Of course, the resistance of the ammeter also needs to be adjusted to avoid damaging the ammeter due to excessive voltage.

Then plug in the power and turn on the power switch.

Instantly, an invisible current flows in the circuit.

Although invisible to the naked eye, they can tell the magnitude of the current through the ammeter.

Look at the size displayed by the ammeter, and then calculate according to the input voltage...

Soon, they came to the conclusion that when the current passes through the superconductor, the current has almost no loss.

Indeed in the category of superconductors!

They looked at each other with excitement on their faces.

With room temperature superconductors, it will bring considerable improvements to everything they study.

No resistors, no damn heat, which also means no current draw.

The circuits will be in harmony, and the electrons will do what they can to serve the consumers.

Xiaorong also appeared on Ye Cheng's face.

It worked.

It was something he had been thinking about for months.

It's really hard.

But soon he shook his head with a grin. If this is considered difficult, those scientists who are trying to conquer room-temperature superconductors are probably going against the sky.

"Okay, let's test again to see if the other nine have also become superconductors."

They processed ten at a time, so of course each one must be tested to avoid the existence of unsuccessful processing.

If there is no successful processing, it means that they need to improve that equipment to avoid the possibility of failure in the future.

Soon, after their inspection, it was determined that the ten niobium-titanium alloys had all become superconductors without any problems.

These ten niobium-titanium alloys, which are fifty centimeters long and one square centimeter thick, may cost hundreds of millions of dollars if you take them out casually, because they all represent an incredible thing, at least for the current human society. of.

It is more surprising than lithium-air batteries, and even more impossible than the realization of nuclear fusion. After all, the superconducting environment required for nuclear fusion can be achieved using the old method, that is, direct cooling to achieve superconductivity. It's just a waste of energy.

However, room temperature superconductors can almost be called divine creations.

It can even be regarded as a new energy storage device. Think about it, after the current is input into it, the superconductor forms a closed loop, because there is no resistance, so the current will not suffer loss when the current circulates inside, and then when needed When it is time, it can be reconnected to the device that needs to input current, so that all the current in it can be released in an instant.

For example, when used on high-energy lasers, it can emit tens of thousands, hundreds of thousands, or even millions of joules of laser light in an instant, which is enough to form extremely terrifying lethality; in addition, it can also be used to share the load on the power grid. When the electricity is low peak, the electric energy is stored to avoid waste, and then this part of the electric energy is input into the circuit during the peak electricity consumption, thereby reducing the load on the grid.

The effect is too much.

If nuclear fusion is the cornerstone of human beings moving towards the future, room temperature superconductors are the structure above the cornerstone.

With such a great effect, Ye Cheng would feel a little uneasy if he didn't make good use of it.

He narrowed his eyes and suddenly had a plan in his mind.

The value of room-temperature superconductors is now only known to him and these system figures.

In the future, he will arrange all the people in the system to be responsible for its production and management, which means that no one else can guess the cost issue.

Then, he can hype room-temperature superconductors like he hypes diamonds.

Of course, his hype is mainly aimed at foreigners.

For the country, of course he needs to give strong support.

For example, building superconducting transmission lines.

In the past, why the high-voltage wires used ultra-high voltage and were made so thick was to reduce current loss. Anyone who has studied physics in high school should know this.

For superconducting power transmission, there is no such worry. Superconductors don’t have to worry about current loss. The voltage can be directly maintained at 220 volts for transmission. Those high-voltage towers don’t need to be built. You only need to worry about the weight of the wires. All right.

And because high-voltage power transmission is no longer used, the safety of power transmission lines will also be greatly improved, which can greatly reduce casualties caused by touching high-voltage power lines.

Therefore, the only question that needs to be considered now is how thick the superconducting transmission line should be.

Thick wires are not only beneficial to reduce current consumption, but also allow greater current to pass while maintaining the same voltage.

Of course, if the wire is thick, the cost issue needs to be considered.

His cost price here is less than 10,000 yuan for a 100-meter-long, 2.5-square-millimeter room-temperature superconductor wire. After mass production, the cost may only be 5,000 yuan.

With 100 million yuan, it is possible to produce 2,000 kilometers long and 2.5 square millimeters thick normal-temperature superconductor wires. Generally speaking, multiple strands of wires are bundled together for transmission, so several strings of 2.5 square millimeters wires need to be bundled together. , In addition, three-phase three-wire transmission lines have to be considered, so three lines are needed.
