It should be known that there is currently no precise and clear definition of the edge of the solar system.

We all know that there are eight planets in the solar system. Neptune is the furthest away from the sun, and the dwarf planet Pluto is outside Neptune. The earth is about 6 billion kilometers from Pluto. The distance of light speed takes 5.6 hours!

But Pluto is not the edge of the solar system, because in principle the influence of solar energy belongs to the solar system! Near Pluto is the Kuiper Belt with a wide range, and beyond it is the wider Oort Cloud!

The Alter cloud is a sphere cloud cluster that is supposed to surround the solar system, and is filled with many inactive comets. It is about 50,000 to 100,000 astronomical units from the sun. The maximum radius is almost 1 light year, that is, the distance between the sun and the neighboring star. One quarter. Astronomers generally believe that the Oort cloud is the remnant of the nebula that formed the sun and its planets 5 billion years ago and surrounds the solar system.

Voyager 1 has been flying for more than 40 years and has not yet fled the solar system. Scientists speculate that it is still flying in the Oort cloud, and the range of the Oort cloud is so wide that Voyager 1 takes tens of thousands of years. Time to fly out of the Oort cloud!

The edge of the Oort cloud is also considered to be the edge of the solar system, which is about one light-year away from the earth. The edge of the solar system is called the "heliosphere", which is the place where the gravity of the solar system and the celestial bodies of the extra-system are balanced, and the solar wind energy reaches The farthest place!

With current human technology, it is unrealistic to want to leave the solar system. It must be able to fly at the sub-light speed to be able to fly out of the solar system. This requires qualitative changes in power propulsion technology!

So the spaceship in Ye Fan's billion-dollar technology crystallization system has the speed of light?

Not available.

If you want to leave the solar system, you must have the speed of light to leave.

And this alone is enough to make countless people desperate.

The speed of light is the speed of light. This is a phrase, not a unit! Ms is the unit of speed, and light year is the unit of length.

And how fast is the speed of light?

The speed of light is constant, and nothing can be faster than the speed of light. However, such a statement is not completely accurate. Its true meaning is that any substance carrying information and energy cannot exceed the speed of light in a vacuum. The speed of light in vacuum is 299,792,458 meters seconds, in fact this value is artificially defined without any error.

The fastest speed of human beings today is nothing but Mach.

The whole conference room was loud and very lively, and Ye Fan's point of view really shocked them.

Whether it is the sun or the dungeon, it is a huge project.

How could it be possible to build countless dungeons that will allow humans to survive in thirty years, or twenty years, ten years?

Isn't that nonsense?

If it is built on the scale of Ye Fan ’s blueprint, it will take at least a hundred years for humans to achieve it?

Even for fifty years.

Fifty years is enough for human survival for more than half.

Building an underground city is not necessarily the kind that everyone must enter.

Everyone is boiling.

But Ye Fan closed his eyes, and began to find a way to save the sun on the list of billions of technological crystallization.

Super jet suction diamond drill bit: The principle of jet suction chip removal is to press the pressure cutting fluid from the cutter body into the cutting zone and use the jet suction method for internal chip removal. The arrangement of jet suction drill teeth is beneficial to chip separation. The cutting fluid flows into the connecting sleeve from the liquid inlet, and one third of them are sprayed from the crescent-shaped nozzles around the inner tube to spray and **** the inner tube. Due to the narrow alveolar gap, the jetting effect generated when the cutting fluid is jetted can form a negative pressure zone in the inner tube. The other two-thirds of the cutting fluid flows into the cutting zone through the inner tube and the outer tube, and the confluent chips are sucked into the inner tube by negative pressure, and are quickly discharged backward, enhancing the chip removal effect.

Super jet suction diamond drill adopts: it is diamond, but not natural diamond. Instead, the instantaneous static ultra-high pressure and high-temperature technology, or the dynamic ultra-high pressure and high-temperature technology, or a combination of the two technologies are used to directly convert carbonaceous materials such as graphite from solid or molten state to diamond. Polycrystalline powder. Synthetic polycrystalline powder can form artificial diamond for industrial use.

Exchange reputation: 1 million!

drill?

Ye Fan saw the drill bit and his eyes twitched slightly.

Sure enough, the second plan is useful. If you want to build an underground city, you will directly send the super drill bit. Looking at the detailed data, this drill bit can dig down to a depth of 300 meters at least every hour.

These three hundred meters are already the top drill bit in the world, and the size of the drill bit is about 30 square meters in radius.

That is to say.

Once a drill bit is dug to the desired depth, the drill bit can be assembled below for a large expansion!

Once it collapses?

Ye Fan had already thought about the collapse problem. The suction spray bit can add the H agent into the drill bit ~ lightnovelpub.net ~ dig all the way and spray the H agent all the way.

The agent H is a technology that Ye Fan once exchanged, and it is applied to the construction unit. With this agent, the walls, concrete, and soil layers can be completely stabilized, which is several times the previous.

With these two, at least in terms of mining, there is a very rapid speed.

Ye Fan looked towards the second unit.

Energy converter: It can refine Bai Jing and release a lot of energy. Each white crystal is equivalent to a year's power consumption in a first-tier city.

The exchange value is: one million!

White crystal.

This thing.

One can reach the power consumption of a first-tier city for a year, is this a bit too exaggerated?

What kind of energy has such a powerful energy?

And the price of this exchange is not bad, it is worth one million.

Look at the price and know that this is a good thing, but what about Bai Jing?

Could there be technology to make Baijing below?

Ye Fan looked down.

Super ion engine: Ion engine is one of the three types of solar electric rocket engine, so it is also called solar electric rocket. Solar electric rockets are new technologies under development and belong to unconventional propulsion systems. It is different from the chemical rockets commonly used in liquid rockets and solid rockets. It works on solar energy rather than chemical energy. The propellant of a chemical rocket engine converts chemical energy into thermal energy, which is accelerated by the aerodynamic heat of the nozzle and then converted into the kinetic energy of the jet gas stream to generate thrust. The working medium of the solar electric rocket engine is heated by the electric energy converted from solar energy or the action of the electrostatic field and electromagnetic field generated by this electric energy to obtain kinetic energy to realize the reaction propulsion.

Exchange value: 1.5 million!
