전기가 없으면 어떻게 될까 ?

 

EMP 효과 [ Electro-Magnetic Pulse effect ]

​

전자기펄스(EMP)로 인하여 나타나는 전자 방출 효과로, 전자기펄스의 영향을 받는 곳에 있는 모든 전자기기는 파괴된다.

​

EMP(Electro-Magnetic Pulse, 전자기펄스)란 핵폭발에 의하여 생기는 전자기 충격파이다.

핵폭발이 일어나면 전자기파와 중성자가 생성되는데, 이때 생성되는 강력한 에너지를 지닌 전자기파인 감마선 광자가

대기 중으로 확산되면서 콤프턴효과(Compton effect)가 일어난다.

​

즉, 고에너지 상태의 감마선 광자가 에너지 단위가 낮은 원자핵과 충돌하면서

원자핵보다 질량이 작은 전자가 방출되는데,

감마선 광자로부터 에너지를 받은 전자의 이동으로 강력한 전기장과 자기장이 형성되고,

핵폭발 이전 단계의 전기장을 강력하게 변동시키는 역할을 하게 된다.

​

이런 과정을 통하여 방출된 고에너지 전자가 물결 형태의 진동 운동을 시행하면서

강력한 전자기펄스, 즉 EMP가 발생되는 것이다.

​

EMP는 전자회로로 들어가 전류가 되는데, EMP가 지닌 에너지가 엄청나게 크기 때문에

회로가 버틸 수 없는 정도의 과전류가 흐르게 되고, 이 과전류가 전자회로를 파괴시킴으로써

반도체로 작동하는 모든 전자기기, 즉 통신 장비, 컴퓨터, 이동 수단, 전산망, 군사용 장비 등이 마비된다.

​

1962년 미 해군이 태평양 상공에서 핵무기 실험을 했을 때, 폭발 장소에서 1,000여 km 떨어진 곳의

관측 장비, 감시 지휘 시스템을 비롯하여 텔레비전, 신호등, 전화 등이 작동을 멈췄는데,

그 원인은 핵폭발로 인하여 발생된 EMP라는 것이 밝혀졌다.

​

그 이후 사람에게는 피해를 주지 않고,

적의 군사용 통신 시스템 및 무기를 비롯한 모든 전력 시스템 등을 무력화하는 EMP 무기(EMP 폭탄)가 개발되었다.

​

현대전은 전자산업에 기반을 둔 통신·무장 시스템으로 진행되는 만큼

폭발 후 0.5~100초 만에 수백~수천km 내의 모든 전자시설을 파괴시키는 EMP 무기가 있으면

적의 지휘·무기 체계를 마비시키는 치명적인 공격을 가할 수 있다.

​

EMP 무기는 크게 NEMP(핵전자기펄스) 무기와 NNEMP(비핵전자기펄스) 무기로 구분할 수 있다.

​

NEMP 무기는 핵폭발 시 방출되는 대규모의 전자기파를 이용하는 것으로,

넓은 영역에 걸쳐 확실하고도 극심한 피해를 주지만 핵폭발의 통제가 어렵다.

​

NNEMP 무기는 핵폭발 없이 EMP를 기계적으로 방출하는 장치를 내장하여 EMP 효과만을 거둘 수 있는 것이다.

즉, 우라늄이나 플루토늄 같은 핵물질이 전혀 들어 있지 않지만 핵폭발에 버금가는 EMP를 방출하여

핵무기를 사용한 것과 유사한 피해를 발생시킨다.

이 무기는 원하는 영역에 한하여 원하는 만큼의 피해를 줄 수 있도록 통제할 수 있다.

​

EMP 무기는 정밀유도장치를 갖추고 있는 항공기 투하용 폭탄이나 순항미사일의 탄두부에 내장된다.

한편 EMP 공격에 대비하기 위한 EMP 차폐 기술도 개발되어 있다.

Why 90% of the Population Would Die Without Electricity

Experts predict that an EMP strike that wipes out electricity across the nation would ultimately lead to the demise of up to 90% of the population.

전문가들은, EMP 공격으로 전국적으로 전기사용을 불가능하게 하여 결과적으로 인구 90% 를 절멸시킬 수 있다고 경고 및 예측한다.

​

제기랄, 뭔 뚱딴지 같은 소린겨 ?

​

우리 인류는 예전에 전기라는 것이 없이도 수천년 동안 잘 살아왔는데

기껏 전기사용 못한다고 갑자기 사람들이 그리 많이 죽는다고 ?

​

​

그렇다. 전기가 없으면 상당히 불편한 정도일 것이라고 생각하기 쉬우나,

사실은 상상 이상으로 참혹한 사태가 벌어질 것이다.

​

전기사용이 불가능해지면 우리 사회에 얼마나 큰 충격이 될 것이고,

결국 90% 의 사람들이 사망할 것인가에 대한 이해하기 위해, 다음 상황을 생각해보기로 하자.

전기가 없으면 마실 물이 없다 (No Electricity Means No Water)

​

Almost no one in the United States still carries a bucket to a well to draw up water. What this means, though, is that our water sources are now dependent on electricity. If an EMP strikes, the vast majority of the population would lose access to fresh water as soon as the water towers run dry.

Some people would be able to find other sources, but many would not. For those without water, the length of their lifespan would be measured in days.

 

​

전기가 없으면 식량이 없다 (No Electricity Means No Food)

​

Those who are able to find water sources not dependent on electrical power now have another concern: food. Almost everyone who lives in an urban location is completely dependent on markets and grocery stores for their food supply. Even those who live in rural locations are largely, if not completely, dependent on buying food from outside sources.

​

However, if the electricity goes out, the supermarkets are going to be looted and possibly never restocked. From transportation to refrigeration, to even the growing of the food itself, our entire system of keeping the population fed is reliant on electricity.

Sure, there will be small farmers who are able to feed small amounts of people nearby, and there will be those who are able to adapt and grow their own food, but an alarming number of people would starve to death in a matter of months.

 

​

전기가 없으면 냉난방이 없다(No Electricity Means No Climate Control)

​

Some areas of the United States, such as Minnesota in the winter and Arizona in the summer, are only habitable because of climate control. If not for indoor heating and cooling, these places wouldn’t have been inhabited by so many people.

Once indoor heating and cooling disappear, surviving during the hottest and coldest times of the year will become a real problem. Some people would relocate or figure out a way to get by, but many who are unable would die of heat stroke or freeze to death.

 

​

전기가 없으면 현대적 의료,치료가 없다

(No Electricity Means No Modern Medicine)

​

Think of all the things that used to kill so many people before modern medicine. From polio to a ruptured appendix, there are countless things that once would have been fatal that are now either treatable or wiped out.

Modern medicine, however, is entirely dependent on electricity. Without it, all of these things would come roaring back with a vengeance. Hospitals that didn’t close their doors would lose a large majority of their effectiveness without all the machines they rely on.

Meanwhile, pharmaceutical companies would be unable to produce the wide array of prescription drugs that are keeping so many people alive.

To make matters worse, the fact that access to fresh water would be greatly diminished means sanitation would become a real problem. Without proper sanitation, diseases would spread at an exponential rate. Due to these factors, no electricity means far more sick people and fewer ways to treat them.

전기가 없으면 범죄가 횡행한다(No Electricity Means More Murders)

​

Within days of the electricity going out, our society is almost guaranteed to collapse into chaos. If you aren’t convinced that would happen, just look at what happens when a natural disaster devastates just a single area of the US, then multiply that by the entire country. Looters would quickly steal anything they could get their hands on, and armed gangs would roam the streets.

Law enforcement would clash with them at first, but they would almost certainly be overwhelmed in little time at all. The chaos would cause people who were once law-abiding citizens to turn to crime, and the number of criminals law enforcement would have to deal with would go through the roof.

In addition, effective law enforcement is largely dependent on good communication and teamwork – both things that become a lot more difficult in a world without electricity.

All of this is to say that, without electricity, going outside your home would suddenly become a much more dangerous endeavor. Those who are able to avoid starvation, dehydration, disease, and death by the elements would constantly have to look over their shoulders to avoid being killed. It’s not a pretty picture of human nature, but it’s a grim reality.

살아남는 10% 가 되려면 ?(How to Avoid Being One of the 90%)

​

As you’re probably well aware by now, surviving in a world without electricity would be a very tall order. The fact that a single detonation could devastate us so completely is disconcerting, to say the least, which is why many of the nation’s top defense experts agree that an EMP is the most troubling threat we would face if we ever went to war with a country that was able to hit us with one.

​

That said, 90% of the population dying without electricity means that 10% will make it, and a little preparation will go a long way toward ensuring you and your family are one of the 10%. Start by making sure you have access to food and water supplies that are not dependent on electricity, and stockpile all the medical supplies you can.

​

If you live in an area where climate control is necessary for survival, either plan for an alternative way to heat or cool your home or put together a bug out bag and be prepared to leave fast. Lastly, make sure to lay low and avoid going out unless absolutely necessary.

​

Surviving without electricity certainly wouldn’t be easy, and the threat of an EMP is one that should not be taken lightly. However, it can be done.
