Earth?"

Hu Liang's words were like a basin of ice water poured on Gao Kai's head. The ice made him stunned for a while, and his original excited expression gradually turned into depression. After a while, he frowned and smiled bitterly: "You're right, yes

I thought wrong, wait for the satellite to come over and report to the ground, and let the higher ups make a decision."

The meeting is over, and there is still a long time before the satellite returns. We cannot give up the work that should be done because of this matter. Everyone should rest and work when they should work. Ye Han returned to the water treatment cabin and took some out of the water tank.

Water is injected into the electrolytic cell, and when the power is turned on, there is no need for human intervention.

Electrolysis equipment can automatically collect gas, compress and liquefy it and store it in cylinders.

The electrolysis equipment was very efficient. After a while, the oxygen tank, which was not much bigger than a brick, was filled with sky-blue liquid oxygen. Ye Han replaced it with a new one, threw the old one on the ground and ignored it.

The cylinder that stores oxygen is particularly interesting. It is not a cylindrical shape that is common on the ground, but a square box shape, and the top cover can be opened!

This design is because the ambient temperature in the crater is lower than the melting point of oxygen. After the liquid oxygen is left for a period of time, it will naturally solidify due to the lower temperature. At that time, the lid can be opened and the solidified oxygen ice can be poured out, like ordinary

The ice cubes are stored together naturally, and there is no need to store them in jars, which is convenient and economical.

Hydrogen is an important industrial raw material. When the base is built in the future, there will definitely be a place for using hydrogen. But the melting point of this thing is too low and it cannot solidify naturally on the lunar surface. It cannot be solidified and preserved like oxygen. Moreover, the temporary base has limited resources and does not have that much storage.

The hydrogen is in a box, so I can only waste a little and let it go.

Using hydrogen storage metal is also a good choice, but hydrogen is made from water. Where there is water, there is hydrogen. The cost is pitifully low. If a lot of money and resources are spent just to preserve hydrogen, it will put the cart before the horse and waste resources.

More than two hours later, all eight air storage tanks were filled and arranged neatly in a row. The huge temperature difference between the tank and the ground caused the temperature in the tank to drain quickly. As long as you wait for a while, the oxygen can be released.

Take out the ice.

The first air storage tank had been thrown on the ground for more than half an hour. Ye Han picked it up and there was no feeling of liquid sloshing at all. He looked at the air pressure gauge again and saw that the pointer had returned to zero.

"This is ready!" Ye Han greeted, and Duan and Xu immediately came over. Under the witness of their two companions, Ye Han opened the lid of the air tank, and a piece of light blue transparent oxygen ice appeared in front of everyone.

Xu Hua praised: "This thing is so beautiful. Even if you don't know this thing, some people will believe it is a gem."

"Then I'll give you this piece to make a set of accessories for your wife." Ye Han handed the oxygen ice to Xu Hua.

Xu Hua took it in his hand and curled his lips: "Put it away quickly. It's the first oxygen brick we've ever made. Let's mark it later. Maybe it will be put in a museum as a cultural relic in the future."

"Forget it," Ye Han laughed, "hurry up and send Curry away."

"Got it!" Xu Hua agreed loudly and sent the oxygen ice into the warehouse as quickly as possible.

Although the temperature of the moon is low, oxygen bricks stored directly in the open air are likely to be lost due to sublimation, so it is safest to store them in a warehouse with a constant temperature.

There was still some water left in the electrolytic cell, and Ye Han said without thinking: "The content of heavy water in this must be more than 6, come and help!"

Ye Han asked his superior Duan Zhiyang to work together, drain the remaining water in the electrolytic cell into a container, freeze it into ice and put it aside, keeping it for the future when the time is right to extract heavy water.
