Demon School - Chapter 723

“Expand the ultrathin solar film!” Fan Yihang stood on the bridge of the Piwei and issued an order. In order to solve the energy problem of space smelting, Lu Qiujian led the team to update the design of the solar film with nanotechnology.

“Ultra-thin solar thin film is completed!” This newly developed ultra-thin solar thin film is less than one micrometer thick. After a single frame is unfolded, the area is more than two square kilometers. The light weight and large area are large. The cost is too high, it is suitable for the field of space smelting.

“Adjust the angle of the solar film array, the specific orientation is a54.62, b251.65 …” Fan Yihang reported a long series of numbers based on the analysis results of the shipboard supercomputer and artificial intelligence.

“Azimuth adjustment is complete!” The astronaut outside the spacecraft immediately completed the position adjustment according to his instructions! Several ultra-thin solar films provide a large solar energy collection area; although the asteroid belt between the orbits of Mars and Jupiter is farther from the sun than the earth, the density of solar energy here is relatively low, but with such a large collection area it is still Collect enough solar energy to melt the ore and complete the preliminary refining.

However, this method is not foolproof. The radiation in the space environment and the damage of tiny meteors to the ultra-thin solar film are the biggest problems in the smelting process! Of course, Xi and the plan have also made detailed preparations. They added an automatic repair function to the ultra-thin solar film, which can reduce this loss to a minimum.

The ultra-thin solar film with an area of ​​more than ten square kilometers projects the solar energy they collect onto the solar generator in the center of the film, and then the generator supplies power to the high-frequency electric furnace! Electrolysis has become the best choice for mankind’s first space smelting.

The mountainous platinum deposits in the smelting furnace began to change slowly under the action of catalysts and high temperature. The ore turned red and bright, and eventually turned into a red liquid!

Then Fan Yihang began the second round of work to remove impurities in the liquid and extract platinum, nickel and iron with higher purity. Since it is not easy to find various raw materials needed in the smelting process in space, they took Two methods, volatile removal and centrifugal separation, are introduced.

For those impurity elements whose vapor pressure is higher than the base metal, they can be removed by volatilization; while other impurities can be separated by centrifuge! And there are ultra-thin solar films to provide a steady flow of energy, these are not problems! Spreading such a large area of ​​solar film on the earth may also cause various problems! But in the vast universe, space is the most important thing! This is even more cost-effective than carrying nuclear fusion fuel.

In addition, there are many advantages to smelting in an environment with no gravity and no atmosphere. There is no furnace gas that contaminates the material in the vacuum, and there is no oxygen to prevent the reoxidation of gaseous metals. It can also reduce the metal reduction temperature and evaporation temperature! A small test that was completed only in the laboratory of the space station has been verified on a large scale here.

Soon the first batch of platinum was smelted, and they naturally formed a spherical shape under a gravity-free environment. If someone measures this sphere through various measuring instruments, they will be surprised to find that this platinum sphere is more than most The artificial sphere should be more standard!

“If it is calculated according to the current market price! The cost of our voyage alone will come back!” Standing on the surface of the asteroid, Fan Yihang, wearing a space suit, easily lifted this platinum ball without gravity. In the environment, every astronaut here is a Hercules! You can easily lift this platinum ball that no one on earth can lift.

“However, unfortunately, when we return to the earth, platinum will probably fall to the price of cabbage?” Yi Meng made a gesture of showing her hands, ruthlessly interrupting Fan Yihang’s yy, but she suddenly yy up again, “wait for this Back to earth this time, how about you replace all the floor tiles of my house with platinum? Is it enough to pull the wind? “

“I say elder sister! You also have to consider a question! This platinum is a metal with excellent electrical and thermal conductivity!” Fan Yihang’s turn is now hitting her, “If you pile a pile of platinum at home, the house will become a fire in the summer in minutes, winter in winter Immediately change the refrigerator! If there is electricity leakage or something! It is even more … And the density of platinum is higher than that of gold! If it is made into the size of a floor tile, the brickworker can take it? I remember your home Really on the 19th floor? If people on the 19th floor use platinum floor tiles, this building will definitely be crushed! But no developer will make the floor load so high! “

“I said that your kid can’t make me happy for a while?” If this is on Earth, I’m afraid Yimeng will start! Do n’t you know that it ’s a sin to interrupt a woman ’s fantasy?

Did n’t you interrupt me first? Fan Yihang didn’t dare to answer, and turned to other questions, he easily lifted this platinum ball weighing tens of tons, “Captain Yi, such a small volume is not easy to transport! We still step up the smelting The asteroid is squeezed out, and then the small platinum **** are fused together to make a big ball and transported back! “

“This is your job! My task is just to send you back and pull it back!” After finishing, Yi Meng grabbed the platinum ball ~ www.mtlnovel.com ~ just stared like a female dragon. Holding the platinum ball to see forever, if not covered by the space suit mask, presumably all the space miners can see her drooling.

After an unimaginable time that is shorter than the mining and smelting process on Earth, this poor asteroid was completely swallowed up by these space miners. The original huge asteroid has disappeared, leaving only three in place. Giant metal **** of different sizes!

They contain the vast majority of platinum, iron and nickel originally on this asteroid! Among them, the platinum ball has the highest density and the largest volume! The iron ball with the lowest density and the lowest price is the smallest, but even the smallest iron ball will be transported to the earth as a huge asset.

“I can finally go back to the earth!” After working in such a vast and quiet and unmanned environment for a long time, people’s psychology will inevitably show various negative changes. Now that the work is completed, they can’t wait to return to the earth .

“Haha, we will definitely make a world sensation when we go back!” The information on the earth was also sent to them through a dedicated channel. They also knew the changes in the platinum market on the earth. “Think about the future of those foreign platinum speculators. Expression, I ca n’t help but want to laugh! That will be very interesting! ”(To be continued.)
