Farquhar didn't want to waste time on Ding's topic, so he began to change the subject, pointing to an Iron Man model and asking, "Mr. Li, what are they working on?" Are the lights and appliances on this model battery-run? ”

Li Xinghe said with a smile: "There are no batteries used, and the surface of this model is coated with light energy paint, which can be obtained through sunlight and ordinary light and converted into electricity. ”

"Light paint?" The old guys heard this word for the first time, and they were all muttering silently, after all, photovoltaics on the earth have been developed for decades, and solar energy is nothing new, but it is the first time that photovoltaics have appeared in the form of paint.

"Oh, that's advanced technology, can we take a tour?" Before Farquhar realized the key to the light paint, his gaze looked at the huge moon next to him.

"Absolutely." Li Xinghe said briskly, and asked Ding Yaxin to continue the experiment after speaking.

Ding Yaxin saw that there was no way to prove himself, so he had to think about it for the time being.

In the past few days, Ding Yaxin has been experimenting with 16 different types of light energy paint products since No. 0 light energy paint, each light energy paint has different functions, of which No. 16 is a paint that can modulate light energy asphalt.

The main purpose of this experiment is to verify the light energy asphalt prepared by Light Energy Paint No. 20, if it proves to be useful, then the national highway renovation in Tongaru country, all roads can be paved with light energy asphalt, and even can be used to absorb geothermal energy for conversion of geothermal energy.

Ding Yaxin has done many experiments before, and has failed several times, either the hardness of the asphalt is not ideal, or the asphalt surface is too slippery, which is not suitable for road construction.

However, this time, because some precious rare earth metals arrived, Ding Yaxin added rhodium and tungsten in the same proportion as the gold light element in the asphalt, and also added a certain proportion of silver element, because the thermal conductivity is still not ideal, silver is the strongest thermal and electrical conductivity element in the world today, and it is hoped that the gold light element can bring greater gain effect to silver, which can also improve the thermal energy conversion rate of light energy paint, and its application range can be wider.

Ding Yaxin is very knowledgeable about the use of rhodium, and when he worked in China in the past, many of the aerospace coatings he invented were excellent because of the addition of rhodium.

Tungsten is not only high in hardness, high in melting point, but also not eroded by air at room temperature, and is the best material to enhance the hardness of asphalt.

Rhodium, tungsten, and even silver are precious metals, and if they are used to pave roads, it is too wasteful, and the roads in some remote areas will be stolen to refine precious metals.

In fact, in the case of gold light elements, the amount of rhodium and tungsten is very small, and the cost is not afraid of increasing.

So this time to carry out a formal experiment, Ding Yaxin is very confident.

After everything was taken care of, the white lamp on the chest of the Iron Man model and the floor lamp on the ground began to shine because of the sunlight.

At this time, Ding Yaxin picked up a hoe, glanced at Farquhar, and motioned him to look carefully.

Then he used it to dig a few times in the mud next to the hoe, and a small pit was dug out of the mud at once.

Ding Yaxin showed the hoe to Faquhar and looked at it, and then backfilled the small pit, this step was actually done for Faquhar to show to prove that the hoe was real.

Next, Ding Yaxin hoeed the asphalt on the ground, and when it sounded, the hoe was notched, but the asphalt ground could not be dug down.

However, no matter how strong the asphalt is, it can't attract the attention of Farquhar and them, this is just an ordinary technology, and it has no gold content.

In fact, when Farquhar said to visit, he meant visiting the satellite, not this light energy paint and asphalt, but unfortunately Li Xinghe did not plan to let everyone visit the satellite.

Ding Yaxin saw that Farquhar was not interested, so he didn't make a surprised expression, so he asked the mold to use an acetylene high-temperature spray gun to conduct a high-temperature test, and especially showed Farquhar the word acetylene on the acetylene tank.

Farquhar was speechless, and there was nothing to do at the moment, so he could only continue watching.

The mold skillfully put on high-temperature gloves, picked up the acetylene high-temperature spray gun, and sprayed directly at the arm of Lizheng Iron Man.

The 3200-degree high-temperature acetylene flame sprays directly on the surface of Lizheng Iron Man, and the light energy paint quickly absorbs energy and converts it into electrical energy, making the white light on the chest of Lizheng Iron Man gradually become dazzling.

Ding Yaxin took an electronic thermometer to measure the surface temperature, and saw that it was only 40 degrees, and his heart beat ecstatically, which means that the thermal conductivity effect brought by the silver element is very significant.

Then Ding Yaxin showed the measured temperature to Farquhar.

Farquhar saw that the electronic thermometer showed a temperature of only 40 degrees Celsius, and once thought that the thermometer was broken, who knew that Ding Yaxin directly reached out to hold the arm of Lizheng Iron Man, and there was nothing at all, so he believed that there was such a magical temperature-absorbing substance in the world?

Then the mold pointed the muzzle of the gun at the asphalt on the ground, and continued to test, usually the asphalt on the road can be sun-dried, but now it can withstand the high temperature of acetylene 3200 degrees, without the slightest sign of melting.

Each test result surprised everyone, and the old academicians were very happy to know that the light energy asphalt of this experiment was a successful invention, which also means that light energy cement can also be invented in the same way.

They consulted Weisha that the total mileage of China's national highways reached 4,773,500 kilometers, and if the whole country uses light energy pavement, it will increase China's power supply by 30%, save energy and reduce emissions by 10 billion tons of carbon dioxide!

This result coincides with Galaxy's intention to focus on environmental protection, although it does not play a significant role in the control of marine garbage and marine pollution, but the future is promising.

Farquhar and other old guys understand that this light paint is by no means an ordinary photovoltaic product, and its fast thermal conductivity represents a high energy conversion rate, and its value is more precious than the coating on the surface of aerospace rockets.

Now it is also made into light energy asphalt, it seems that Galaxy Technology has planned to skip the military use of aviation and directly carry out the civilian field, which can only be done in a small country like Tongalu, in exchange for the First Brother Empire, such a powerful technology has long been 'bought' by the military, or 'taken' by the capitalists by various means.

Moreover, once the light energy paint is applied to the surface of the satellite or the surface of the spacecraft, it can obtain a steady stream of energy in space, which is of incomparable help to space exploration.
