EMP & Solar Protection Technologies specializes in products that offer EMP Protection from solar storms, electromagnetic disturbances and wireless identity theft.
Emergency electric generators may provide the only source of electric power for days, weeks or even months following an EMP Catastrophe.  Protecting portable electric generators should be a national priority for every household and business. This is a tubular role cage, a mass-produced item, used to house portable generators and welders.
An electromagnetic pulse, or EMP, may sound harmless enough but its effects can be devastating. EMPs can occur naturally, as with lightning and a case we will explore later in this article, as well as through man-made sources such as nuclear or radio-frequency (non-nuclear) weapons.
Modern day reliance on the power grid leads many preppers to classify EMPs as a serious threat. The following article will teach you the basics in understanding what an EMP is, how it can be caused, and the short and long term effects. These free electrons then interact with Earth’s natural magnetic field creating a current that is powerful enough to decimate electrical currents over a large expanse of area.
As devastating as a nuclear explosion is, the resulting EMP can reach even further than the physical destruction of the blast. In 1997, Gary Smith, then the director of Applied Physics Lab at John Hopkins University, testified in front of the House National Security Committee that a nuclear detonation at 300 miles above the surface of the Earth could carry enough impact to knock out electrical power to the United States as well as most of Canada and Mexico (click here for source article). However, nuclear weapons are not the only ones capable of generating an EMP; more localized sources of energy such as radio-frequency weapons or non-nuclear EMP devices can also wreak havoc.
Instead of drawing energy from a bomb explosion, these devices use concentrated microwave energy to cause disruptions in electronic equipment and destroy data. The cause was later attributed to a group of sunspots that were 1.9 billion square miles in size. Despite the increased vulnerabilities present in modern times due to the prevalence of electronic devices in managing day-to-day activities, a future natural EMP event will likely come with advanced warning thanks to the benefit of space-monitoring stations. A solar event would take hours, or even days, to reach Earth’s atmosphere, providing enough warning to safely stow electronics and turn off power systems (while shutting down power will not completely immunize systems against damage, it certainly can reduce the risk).
Additionally, any cars relying on high-tech computer systems (basically any model manufactured in the last 20 years) would be disabled and back-up generators could experience malfunctions or be ineffective if the existing equipment is damaged.
Recovery from an EMP is dependent on the size of the affected area and location, but could potentially take many years. If you are serious about protecting yourself and your family from the threat of an EMP strike I strongly suggest you CLICK HERE NOW to check out this report.
Simulators can be used to test the effectiveness of Faraday cages in diverting incoming energy. A Faraday cage can be built to any size to accommodate myriad manner of objects; keep in mind that an EMP can cause a voltage spike powerful enough to fry all manner of electronic devices, including cell phones, computers, radios and appliances. The manner in which a Faraday cage can protect against an EMP is by using the conductive layer to diffuse energy rays (this is why it is imperative to have no openings through which energy waves can pass). There is a very simple way to test the effectiveness of a Faraday cage: place a working cell phone in the cage and try calling it. The best way to prepare yourself and your loved ones for an EMP is to prepare for the aftermath by ensuring you have adequate stockpiles of food, water and other essentials. Not only will having the supplies ready beforehand ensure you have enough to last, but also, in a worst-case scenario, there may be civil unrest or upheaval that makes it dangerous or impossible for you to leave your home, necessitating having sufficient supplies on hand.
In addition to preparing for the aftermath, having a Faraday cage built and ready to go is a measure you may choose to take to protect your household devices in the case of an EMP. Laying a piece of cardboard on the floor as you load items into the closet can help prevent damaging the foil.
If you don’t have a closet ready to go, or are prepping a location that is not in a home, you can build a freestanding Faraday cage by framing a box with 2x4s and then lining the outside with fine, conductive mesh. In place of mesh, you can also use sheets of aluminum or copper for your shielding material.
For smaller devices, something as simple as a shoe box lined with heavy-duty aluminum foil can do the trick. If you are considering building your own Faraday cage, make sure to check out this article and other resources with detailed building instructions. You may already have a store bought Faraday cage ready to go and not even be aware of it – your microwave oven.
There are also anti-static bags, available in a variety of sizes, that can protect against electrostatic discharge and are easy to store in your get home bag.
The effectiveness of your Faraday cage in protecting your devices against an EMP is dependent on a number of factors, including the origin of the EMP, how far your Faraday cage is from the EMP, and the type of rays emitted by the EMP. High frequency waves require smaller holes in the meshing while short-range EMPs contain gamma rays and xrays that cannot be blocked by only a single layer of heavy-duty foil. In today’s technology-enabled world, it is easy to imagine the devastating consequences that could arise from a prolonged loss of power. While Faraday cages provide an effective means of first-line defense against EMPs, remember there may be little to no warning before a strike and you may not have the opportunity to put your Faraday cage to use.

An electroscope under a metal cage will not be affected by a charging Van de Graaff generator, even if the generator is close enough that sparks jump to the cage. A metal ball is charged using a Van de Graaff generator and then lowered into a metal pail.


The Static GENECON is a unique demonstration instrument designed to allow teachers and students to conduct a variety of electrostatic experiments.
Even the Police have some new small Faraday bags for confiscated cell phones a€“ to preserve information. Back in 2004, The Congressional Study EMP Report indicated potential casualty rates of 90%. To avoid a total collapse every American should have some EMP hardened equipment or at least a Faraday Cage to protect the most important survival electronics.
A Faraday cage is a sealed enclosure that has an electrically conductive outer layer and a non-conductive inner layer.
Tip: if you can call your phone, then wrap the box in another layer of aluminum foil and try again. The principle is the same (as Pasta box)a€¦ just that this one is larger and can be opened every time you want without tearing up the foil. But chances are that you have a normal bird cage, which will work as a Faraday cage if you place some foam (for example) in it. If it does not work, it probably means that the holes are too big so youa€™ll have to wrap the cage in aluminium. Line the trash can with cardboard (or carpet padding), including the bottom, making sure there are no gaps.
You can fit here a lot more electronics including an old laptop with your survival books and maybe a very small generator or a small solar panel. You dona€™t want the nails (which the box already has) to connect the aluminum foil with the inside of the box. Just line the inside with cardboard (including the lid) and put in the electronics you wish to protect from EMPa€™s.
After the nuclear EMP was discovered in 1962 (US Starfish Prime Experiment) people have been searching for all kind of methods of protection (against electromagnetic pulses).
If you are not familiar with the destruction effects of an EMP, you should probably watch this short documentary and learn what the biggest threat to modern-day America is, and what you can do today to keep your family safe. Even the Police have some new small Faraday bags for confiscated cell phones – to preserve information. The principle is the same (as Pasta box)… just that this one is larger and can be opened every time you want without tearing up the foil.

Just line the inside with cardboard (including the lid) and put in the electronics you wish to protect from EMP’s. If you find it too hard to line the inside of the box, then try this: put your phone (for the test) in an anti-static drive bag (plastic) and then put it in the tin. Using a cell phone to test your Faraday cage is a poor test, as it’s very easy to block those high frequencies.
Unless these are sealed with adhesive aluminum tape (or something better), the lids and doors will act as slot antennas. RE the cars , When I was younger fuel trucks would have a chain which would drag and ground out any static electritcity.
I think a chest freezer or refrigerator with motor and internal plus eternal heat exchangers removed with aluminium foil grounded to the outside casing blocking gaps would be ideal for the job.
This fellow has gone to great lengths to test the validity of using a metal garbage can as a Faraday cage. To preference my qualifications I am an electrical contractor and trained by the Navy in electronics.
An EMP is essentially an intense burst of energy (for instance a lightning bolt, which is simply a highly concentrated EMP event that is very localized) that, depending on size and intensity, could potentially wipe out electrical and information systems across vast areas. This article also explores Faraday cages and how they can work to protect you against EMPs, discussing the features that are most important and various types you can purchase and build yourself.
The lasting effects of an EMP can range from minor inconvenience to potentially sending the world back to a pre-communications technology ‘dark age,’ so to speak. In what is referred to as the Compton effect (named after physicist Arthur Compton who first theorized of the effect), the theory follows that when a nuclear bomb explodes, the explosion releases electromagnetic energy which binds to molecules in the atmosphere and releases bonded electrons. While these devices deliver a non-lethal pulse, the damage to electrical systems is no less devastating than with a nuclear detonation.
While these occurrences are infrequent, a geomagnetic storm in 1921 affected the United States as well as parts of Europe for two days, closing the New York City railroad system and burning telegraph lines in Sweden.
Today, a storm of this size would affect over 100 million people and cause widespread panic and chaos due to society’s heavy reliance on electronic devices for everyday life. Depending on the intensity of the pulse, EMPs can start electrical fires, incapacitate power grids, and shut down power sources for refrigeration (causing loss of food and medical supplies), water and sewage services, security systems, and phone and Internet (this would affect financial institutions and ATMs as well as land, sea and air transportation). A popular method of EMP-proofing is to use a Faraday cage, a protective container equipped with a conductive outer layer that is typically made from aluminum. The term ‘cage’ originates from the fine metal mesh often used as a protective wall; however, research indicates that using a solid sheet of metal may be more effective (more on building your own faraday cage later on).
The only must-have in constructing a Faraday cage is that it needs to be thoroughly lined by a conductive material with no gaps.


The process is referred to as field cancellation, with ions in the conductive material realigning themselves to cancel the incoming electric field.
A properly functioning Faraday cage will block the signal and the call will not go through.
In the event of widespread electricity loss, store shelves will quickly empty and essential resources will become scarce.

When constructing your shield room, be sure to pay careful attention to how your foil is placed around the door frame so that it provides a continuous shield. Additionally, check for any outlets in the closet and ensure nothing is plugged into them and that they are also covered with foil. Remember, the openings on the mesh must be small enough to prevent energy waves from entering. Whatever material you choose, ensure its coverage is continuous over the entire exterior of your cage, or else its shielding effects will be rendered useless. Alternatively, you can wrap your devices in several layers of foil, which also functions as an effective means of protection. While most people are familiar with their microwave’s ability to keep radiation in, few are aware that a microwave can also keep radiation out. To fully protect against EMPs from radiofrequency weapons, thick sheets of metal are required. A larger EMP that destroys power for several weeks, or even months, could easily lead to civil unrest and throw many first world residents into a survival situation. The best way to prepare for an EMP event is to prep yourself and your family for the aftermath, ensuring your stockpile of supplies will be adequate to see you through a potentially long-term spell of power-free living.
When placed outside the metal cage, it will show the generator's effects, even if at 1 m away. Maine has become the first state in the nation to pass legislation ordering its grid to be hardened against an electromagnetic pulse. If you dona€™t wrap it completely in aluminum foil youa€™ll be able to call yourself from another phone. According to Radasky, that country during the cold war hardened some of its critical infrastructure against EMPs, such as water works. Recently, NORAD has moved its communication equipment back to its nuclear Cold War-era bunker under the Cheyenne Mountain because this base is EMP hardened. The purpose of this box is to protect any electronics inside it in case of an EMP. I’ll also show you how to test your Faraday Cage (it’s easy). If you don’t wrap it completely in aluminum foil you’ll be able to call yourself from another phone. Then I put it a 9 volt battery package for insulation and then opened a copper brillo type pad and wrapped it around the little package. Even without modification because of the insulation by just placing items in a heavy duty bin liner would probably do the trick Simple but effective. Do light bulbs, batteries and solar panels have to be in a faraday cage to be safe if there were an EMP?
To test your microwave’s effectiveness, unplug it (this is an essential first step, do NOT attempt this exercise while the microwave is plugged in) and run the cell phone test discussed in the previous section, How Can the Efficacy of Faraday Cages Be Tested? When the cylinder is connected to a Van de Graff generator, the pith balls hanging inside move slightly. In this case, the box was perfect and I couldna€™t call my phone because there was no signal in it. Remember to isolate the bottom of the box (with wood, cardboard or plastic) and to keep away the electronics inside from the Aluminum Screen.
If you dona€™t use on a daily basis what you want to protecta€¦ just keep it in its original box and wrap it with heavy duty aluminum foil. In this case, the box was perfect and I couldn’t call my phone because there was no signal in it. If you don’t use on a daily basis what you want to protect… just keep it in its original box and wrap it with heavy duty aluminum foil. A better test is to use an AM radio, particularly when you’re standing next to a 50 kW transmitter.
Anyway, the phone test is 99% accurate, because the phone signals are a bit higher in frequency than an EMP.
Moving the ball around the inside of the pail, even touching the inside surface has no effect on the potential shown by the electroscope leaf. If you want to be 100% sure that you made an EMP hardened Faraday cage then you should place a small turned on radio. After the ball has been lifted, the inner surfaces of the pail and ball are found completely free of charge, which can be checked with the help of another electroscope.
If your doctor says you have a 5% chance of dying a€¦ wouldna€™t it be crazy not to do something about it? If your doctor says you have a 5% chance of dying … wouldn’t it be crazy not to do something about it?
