Half-immortal civilization

Magnetic engines have long been compared to milestones in the new era of human civilization.However, compared with electricity, magnetic energy has always been an elusive "energy", which has made it difficult for humans to use magnetic energy.

Simple electromagnetic technology has promoted the great development of mankind. Large ones such as magnetic smelting furnaces and magnetic levitation technology, and small ones such as simple stereos and motors, are all comprehensive developments of electromagnetic technology, even including Sinan back then.

However, in the development of high-end fields, electric energy has always been the champion, and magnetic energy has been far behind.Without him, elusiveness is the biggest problem.But now, when the powerful magnetic energy is bound, it produces a powerful change!A new technology beyond classical physics broke out!

In classical physics, no matter what kind of force it is, it acts on itself or on visible objects such as air and ground.And the object of the magnetic motor is actually the space itself!
To make a metaphor, a magnetic engine can make a spacecraft fly in space, just like a car running on the ground, using space itself to save energy, which can increase energy efficiency by dozens of times, or even exceed its own energy efficiency.

Just like a car engine, it only has a force of a few thousand kilograms, but it can drag a load of tens of tons. In contrast, the current space shuttle can only transport objects under one ton per ton of thrust. I can't fly anymore!
The current magnetic motor has such an effect, superimposing the mass of the spacecraft on the space, and then doing work on the space level. Although this will cause problems such as slow speed and high resistance, it has more advantages!
Follow the countdown.Everyone exited the research room, waiting for the results of the experiment.If it succeeds, then this space age will turn a new page - with the super-large-capacity ground-air transportation vehicle, space development will really start a cheap leap forward!

Of course, the above is only a theoretical conjecture, and the specifics depend on the actual results of the research.

The countdown ended, and the laboratory was quiet without any noise.Could it be that the experiment failed?

No!of course not.The magnetic motor is noiseless, because it does not produce the rotation of the machine, does not produce the jet of air, and does not produce particularly obvious noise.There may be some electromagnetic noise.But after passing the lab's high-spec walls.Can't hear it anymore.

Squeak... The dome above the laboratory slowly opened, and a shining elf, like a white cloud, floated gently and slowly leisurely; as if it had no weight.Fly gently into the sky.

"Success!!!" The scientists cheered.Some even shed tears.for this technique.On the existing basis, thousands of people have still made efforts for more than ten years.For ordinary people, how many decades are there?The prime time for scientists is generally only 20 years—ten years.Halfway past prime time!
By this time, there was already a slight sound of the motor working.

Before Zhang Jingyuan could open his mouth to ask, Dongfangying had already taken the initiative to explain.It turns out that the magnetic motor is an ultra-cooling technology, and its working temperature must be kept below minus 170 degrees; for this reason, it has to be equipped with a powerful cooling unit.The current magnetic motor is still relatively primitive, with the lowest working voltage of several hundred million volts or more. It generates a lot of heat, and the violent vibration of the magnetic field will also generate heat. In order to ensure the normal operation of the unit, it has to be equipped with powerful cooling measures.

"Oh. So what is the overall efficiency of such an engine?" Zhang Jingyuan must break the casserole and ask the end.

"Well, it's still a little primitive." Dongfang Ying blushed, which was rare.

This time, Zhang Jingyuan also smiled, "I'm just asking about efficiency, a number."

Trembling, Dongfangying stretched out three fingers.

"30.00%? If that's the case, it's pretty good for a new thing."

Woooooooo... Dongfangying shook her head like a rattle.

"Three percent!!!"

Finally, Dongfangying nodded shyly.

I... Zhang Jingyuan didn't know what to say for a moment. 3%! 3% efficiency... Are you sure this flying saucer can carry other weights besides its own weight?It won't be an expensive toy!

As if seeing Zhang Jingyuan's idea, Dongfangying began to explain: "Although the efficiency is very low, you can see that the current flying saucer is 30 meters in diameter and weighs more than 350 tons, of which the power system and energy storage system total 50 tons, and the rest are all The flying saucer is self-respecting.

But now the flying saucer is seen flying into the sky lightly, which obviously has a lot of power.The specific load, etc., as well as the efficiency of the engine, will continue to improve in the later stage.

In fact, it is already very good to be able to successfully research the engine.And because its power directly acts on the space, it actually increases the efficiency of the engine dozens of times.Overall, the current relative efficiency is about 75%. "

"Then continue to research. It is already very good that the new technology can be successful. In fact, the turbine power system has a history of 200 years from the research and development to the present, and this is how the current plasma engine can be achieved; such achievements can be achieved within ten years. It’s already amazing!” The development and upgrading of technology cannot be solved overnight.In fact, Zhang Jingyuan was very satisfied with being able to succeed.So not demanding too much.

And now the overall efficiency of 75% seems to remind people that the law of energy conservation is still the cornerstone that cannot be challenged!Maybe the magnetic motor itself has high efficiency, but it also generates a lot of heat, consumes a lot of energy, and needs to be equipped with a complex cooling unit!

But fortunately, it succeeded after all.In addition, even if it is true that the energy cannot exceed 100% on the ground, what about in space?You must know that the cooling in space can be done naturally without cooling units!However, it seems that in space, the magnetic motor and the plasma motor are comparable!

Well, the future of magnetic motors is bright.That is, there is still work to be done.

However, the development on the ground is good, and the development in space is even stronger.Without the shackles of gravity, without the resistance of air, let everyone realize too many designs that cannot be realized on the ground!

The most eye-catching thing is the super-large spaceship that is about to be completed.

It is more than 1100 meters long and 90 meters high, and its body is covered with huge "scales" - those are engine modules!Each of these scales has a 5000-ton thrust Tiger Gallbladder No. 1000 engine.There are actually 500 such engines on the entire spacecraft, and the overall thrust is as high as 70 million tons!The self-weight of the spacecraft is only 1.5 tons.Inside, it is stuffed with the latest physical batteries, carrying up to 50 trillion kilowatt-hours of electricity. The spacecraft works at full capacity and can only work for [-] hours.

But this spaceship named "Giant" is not used for transportation, but for - dragging the planet! ! !

In fact, in such a huge spacecraft, there is only a 30-meter-long and wide control room, and the rest of the place is filled with physical batteries, complex power systems, and so on.This is simply a monster of an era!After this era, it can only be sealed!

"Target, Ceres!" Zhang Jingyuan was magnificent, and through the glass cover of the space base, he pointed at the lonely and almost invisible Ceres in space, the only dwarf planet in this asteroid belt! (To be continued..)
