Crossing the World

XLIX - Shelters (Karen)

Four days after I recovered, the blue-blooded humans finally made it to the area taken care of by the AI. I greeted them right when they first arrived, but nothing interesting happened there afterwards.

By this time, about twenty percent of the trees we planted had been fruitful and a small portion could already be harvested. Rain will fall artificially and periodically at least once a week. AI has also set up a simple wooden house that is about fifty kilometers away from the bunker. So, they should both be able to survive on their own in this land.

Most of my time is spent carrying data on the method of conducting electricity without wires. I also brought some of the raw metals from the earth that AI needs to build the system.

The next few days were a busy activity. I kept making space jumps between the two worlds just to help the AI in assembling everything. Well, it looks like building a cordless power grid is no simple matter.

"All that remains now is the design of a spacecraft to be used as a solar mine." AI spoke to me while we were in the recreation room.

The next few days are the timetable by which earth representatives should return to visit the artificial islands. In other words, the day I could discuss the matter of the space shuttle with Earth.

I have been looking for articles on the internet about the plane. However, as I had expected, such a complex thing was impossible for me to find for free. So, there was no other way but to ask the earth representative directly who could at least try to get the information I needed.

The reward I would give for exchanging such valuable information was a chunk of gold and silver-colored metal with a density of one hundred kilograms of cubic permeters each side of which had the opposite nature. Yes, it is a unique metal that does not exist on earth. The name of this metal is Peruche.

When the other side is given a hot temperature while the other side is given a cold temperature, then this metal will produce a DC electric current. Vice versa, if the electric current is flowed, then both sides of the peruche will be hot and cold. The greater the temperature difference between the two sides, the greater the electricity produced.

Isn't that similar to peltier on earth? What is so special about peruche?

In contrast to peltier, when heated, peruche itself only gives off less than 0.00005% heat on the reverse side so it does not require too intense treatment. In addition, there is one thing that distinguishes between peltier and peruche metal.

Peruche has almost absolute resistance to heat and cold. Peruche parts that function to absorb heat can withstand heat up to 340 million degrees Celsius and parts that emit heat can withstand cold temperatures to absolute zero, namely -273 °C. In addition, the properties of this metal also isolate radioactive up to one hundred percent.

Then, how to melt and shape the peruche to the desired shape?

In its liquid form, the gold peruche that should be heat resistant will melt and mix perfectly with the silver part. However, as the temperature cools further, these two parts will separate by themselves. The silver side will be at the top while the gold side will always be at the bottom. I think this is because of the difference in density.

When in stable condition, peruche is even about a hundred times stronger than tungsten carbide. So, even the most advanced penetration bullet on earth will not be able to make scratches on the surface of the peruche.

The usefulness of peruche itself is extraordinary. If we make it as thin as glass and shape it into a closed dome, we can create a combustion chamber for nuclear fusion reactions. Heat from nuclear fusion that can penetrate the numbers up to 250 million degrees Celsius can heat peruche and produce electric energy in amazing quantities.

Yes, at least peruche on earth has a very valuable value.

In this world, the application of peruche unfortunately still can not be applied now. The problem is simple, because there is not enough cold air to produce a safe power plant.

If we build a nuclear power plant here using peruche, we need to build a cooling system as well so that peruche can produce electricity much more safely. I mean, the air temperature during the day can penetrate the number 60°C. If coupled with a sunburn during the day, the figure will be on the verge of melting peruche. Unfortunately, building a cooling system means having to use electricity as well and the potential for environmental damage is getting higher if we force ourselves to build a giant cooling system here. Meanwhile, if we do not make any cooling system, the silver part of peruche will melt due to the scorching heat during the day. We might be able to use a peltier to cool it down, but who would dare carelessly try it? Leaking one centimeter only then the planet will turn into an incandescent ball.

Another with the earth. The thick ozone layer makes it possible to build power generation systems using peruche. They could build power plants in very high altitudes, polar regions, or other icy deserts and rely on nature to cool the peruche. If necessary, they could build it on the moon to take advantage of natural coolers while building a cooling system without fear of damaging ozone in the event of a leak.

If you do not expect to make a very efficient power generation system, cooling the outside of the peruche in running water is also no problem. However, this only happens on earth. I mean, here water alone is very hard to come by, let alone running water.

Well, actually if only we could build a solar power plant in space, we would also definitely build a peruche there. Even so, since the number of peruche is so abundant, giving a few tons to the earth would not be a problem.

Therefore, let's give peruche to earth if they want to help me build a plane to mine the energy in the sky.

Holding such confidence, I prepared a small chunk of peruche in my hand and instantly made a space leap towards the artificial island to prepare for our second official meeting.
