Why This Skill Matters in an Emergency or Survival Situation

An Electromagnetic Pulse (EMP) is a burst of electromagnetic energy that can disable or destroy electronic devices and systems. In a survival scenario, protecting your vehicle and electronics from an EMP is crucial because it ensures your transportation and communication tools remain functional. Without a reliable vehicle, you might be stranded, and without communication devices, you could miss critical updates or calls for help.

What You Need

Materials

  • Faraday cages or containers: Metal boxes or containers lined with non-conductive material like cardboard or wood. Alternatively, you can use metal trash cans or ammo cans.
  • Conductive shielding material: Copper or aluminum foil, or conductive paint.
  • Vehicle protection: EMP blankets or Faraday cages designed for vehicles.
  • Electronic devices: Ensure you have all necessary devices inside the Faraday cages before an EMP event.

Tools

  • Scissors or box cutter for cutting materials
  • Tape: Electrical tape or duct tape
  • Paintbrushes for applying conductive paint
  • Screwdrivers or other tools for modifying containers or vehicles

Knowledge

  • Basic understanding of electromagnetic fields and how they interact with conductive materials
  • Familiarity with the devices you plan to protect
  • Basic electrical knowledge to understand how to properly store devices

Step-by-Step Instructions or Key Techniques

Creating a Faraday Cage

  1. Choose a Container: Select a metal box or container that can be sealed tightly. Trash cans and ammo cans are popular choices.
  2. Line the Inside: Line the inside of the container with cardboard or wood to prevent direct contact between the metal container and the devices inside.
  3. Wrap in Foil: Wrap the container in multiple layers of aluminum foil. Ensure there are no gaps or holes.
  4. Seal the Container: Close the container tightly and secure it with tape if necessary.
  5. Test the Cage: Place a small electronic device inside and test its functionality after placing it in the cage and turning off the power. The device should not function when the cage is closed.

Protecting Your Vehicle

  1. EMP Blankets: Purchase or make EMP blankets designed to cover the vehicle’s sensitive components. These blankets are typically made of conductive materials.
  2. Faraday Cage for Vehicles: If possible, create a Faraday cage within the vehicle. This might involve lining the interior with conductive paint or using a mesh Faraday cage design.
  3. Store Devices Inside: Keep critical devices like GPS units, radios, and smartphones inside the vehicle’s Faraday cage or blanket.
  4. Test the Vehicle: While you can’t easily test the vehicle’s functionality without an actual EMP event, ensure that all devices inside the Faraday cage or blanket are functioning properly before an event.

Common Mistakes and How to Avoid Them

  • Not Testing: Always test your Faraday cages and blankets before an EMP event. Ensure that devices inside are non-functional when the cage is closed.
  • Improper Sealing: Ensure that all Faraday cages are properly sealed to prevent electromagnetic energy from entering.
  • Overlooking Vehicle Components: Protect not just the electronics inside the vehicle but also the vehicle’s wiring and ignition systems.
  • Using Insufficient Layers: Multiple layers of shielding are necessary to ensure effective protection against an EMP.

Variations, Tips, or Related Techniques Worth Knowing

  • DIY Faraday Cages: You can make your own Faraday cages using everyday items like microwave ovens or metal trash cans.
  • Conductive Paint: Using conductive paint can be a more elegant solution for protecting larger areas or vehicles.
  • EMP Blankets: These are specifically designed to protect vehicles and can be a more convenient option than building a Faraday cage.
  • Battery Backup: Ensure that all devices inside Faraday cages have a battery backup or are charged before an EMP event.

TLDR

Protecting vehicles and electronics from EMP requires creating Faraday cages or using EMP blankets. Ensure proper sealing and testing before an event. Avoid common mistakes like insufficient layers or improper sealing. Consider DIY options and battery backups for added protection.
