How can I harness the current induced in a Faraday cage for practical use?

Click For Summary
SUMMARY

The discussion centers on utilizing induced current within a Faraday cage, specifically a cut pop can, to harness electromagnetic waves. Participants confirm that while current is indeed induced in the cage, effectively channeling this current for practical use poses significant challenges. Suggestions include the potential for heating the can, although this method is inefficient for substantial energy capture. The consensus is that without a mechanism to channel the current, the cage primarily functions as a receiving antenna rather than a power source.

PREREQUISITES
  • Understanding of electromagnetic waves and their interaction with conductive materials.
  • Knowledge of Faraday cage principles and their applications.
  • Basic concepts of electrical current and its behavior in circuits.
  • Familiarity with energy conversion methods and efficiency considerations.
NEXT STEPS
  • Research methods for channeling induced current from a Faraday cage.
  • Explore energy harvesting techniques from electromagnetic waves.
  • Investigate the efficiency of using conductive materials for heat generation.
  • Learn about antenna design and its role in capturing electromagnetic energy.
USEFUL FOR

Electronics enthusiasts, engineers interested in energy harvesting, and researchers exploring electromagnetic wave applications will benefit from this discussion.

There is my uh rudamentary drawing of a scenerio where something emitting em waves(green) is surrounded by a faraday cage(yellow). umm I believe current is induced in the 'cage', how would I divert the current to use, because if I am correct the current has to has reason to leave. How could i use it on a load, or anything?

Any suggestions of anything that could help me along here?

P.S. I am actually using a cut pop can as the faraday cage.

There is no way to channel the current without losing the shielding effect.
What you would have then is just a receiving antenna.
The only use I could see of the current is to heat the can,
but it would be hard to get much heatng this way.
