Protecting Your Computer from Solar Storms - Is a Faraday Cage Enough?

Click For Summary

Discussion Overview

The discussion centers around the potential impact of solar storms on electronic equipment, specifically whether placing a computer inside a Faraday cage would provide sufficient protection against damage. The scope includes theoretical considerations of electromagnetic interference (EMI) and practical implications for electronic devices during extreme solar events.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses concern that strong solar storms could cause irreparable damage to electronic equipment, questioning the effectiveness of a Faraday cage in preventing this damage.
  • Another participant notes that while Faraday cages can block some transmissions, extremely strong signals may still penetrate, depending on factors like mesh spacing and wavelength.
  • A different participant highlights the broader implications of a severe solar storm, suggesting that power supplies could be down for an extended period, complicating the utility of computers.
  • One participant references the concept of a "black start" for electric grids, indicating the challenges of restoring power after a complete shutdown.
  • Another participant combines concerns about solar storms with other global crises, suggesting a pessimistic outlook on the future of technology and electricity availability.
  • A later reply emphasizes that additional protective measures, such as filters and transient suppression devices on cables, are necessary for comprehensive protection beyond just using a Faraday cage.

Areas of Agreement / Disagreement

Participants express a range of views on the effectiveness of Faraday cages, with some acknowledging their limitations. There is no consensus on the overall impact of solar storms on electronic devices or the adequacy of protective measures discussed.

Contextual Notes

The discussion includes various assumptions about the severity of solar storms and the effectiveness of different protective strategies, which remain unresolved. The implications of power outages and the interconnectedness of global crises are also mentioned but not fully explored.

Who May Find This Useful

This discussion may be of interest to individuals concerned about the effects of solar storms on technology, those exploring protective measures for electronic devices, and participants interested in the broader implications of electromagnetic interference.

From what I understand in scientific publications, if there is a strong solar storm directed towards the Earth, the effects would be such that any electronic equipment would suffer irreparable damage. I ask, if I put my computer inside a Faraday cage would it also be damaged?

Welcome to PF!

While Faraday cages can block some level of transmission, it’s always possible that an incredibly strong transmission can reach the gear inside the cage.

Notice that what the cage can block is dependent on the mesh spacing and the wavelength of the transmission ie slow changing transmissions ie large wavelength can get through.
 
Hello and :welcome: !

What for? Our power supplies will be down for years if the storm is heavy enough. They estimate that it will take up to ten years to replace all the insulators in transformation facilities.
 
Couple that solar storm report with the UN report on climate last week plus new COVID variants more deadly than Delta, plus all the volcanoes and earthquakes, and I guess the end of the world is nigh.

@fresh_42 is right. If the world has no electricity, there's not much use for computers.

In addition to using a shielded room to protect equipment from the strong ElectroMagnetic Interference (EMI), you need to put filters and transient suppression devices on the cables that connect the equipment inside the room to power and data cables outside of the room. It does little good to use a shielded room if the cables are not filtered and protected too.

They make good conversation pieces, door stops and coasters.
