Discussion Overview

The discussion revolves around the concept of harnessing magnetic flux from lightning-powered electromagnets. Participants explore various design considerations, potential applications, and the challenges associated with using lightning as a power source, including insulation, material selection, and energy management.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants speculate on the amount of magnetic flux that could be harnessed from a lightning-powered electromagnet.
  • Concerns are raised about the size and material of the windings, with suggestions for using large diameter cables and ceramic insulators to withstand high temperatures and voltages.
  • There are proposals for using fluid-filled tubing for cooling, though questions arise about the potential for steam pressure to cause explosions.
  • Some participants discuss the feasibility of creating a rail gun powered by lightning, with ideas for competitions to measure performance.
  • Alternative methods for increasing the likelihood of lightning strikes, such as using balloons to carry cables into clouds, are suggested.
  • Historical references are made to past experiments with lightning and energy storage, including Ben Franklin's work with Leyden jars.
  • One participant argues that the energy from a lightning strike is too brief to be effectively harnessed, suggesting a focus on the potential difference that creates lightning instead.
  • Concerns about the high frequencies in lightning strikes affecting the buildup of magnetic flux are also mentioned.

Areas of Agreement / Disagreement

Participants express a range of ideas and concerns, indicating that there is no consensus on the best approach to harnessing energy from lightning or the feasibility of the proposed designs.

Contextual Notes

Participants highlight various assumptions about materials, energy management, and the nature of lightning strikes, which remain unresolved. The discussion includes speculative ideas that may not be practically achievable.

Zooby, naturally the insulation has to break down in order for there to be arcing between turns. But the inductance of the coil will prevent any high frequency currents from discharging THROUGH the turns of the coil. An easier path is to arc around it, or from one turn to the next to the next to the next and so on. I realize tesla coils generate high frequencies. Usually nothing above several Mhz. Lightning will generate frequencies much higher than this.
OK, I see what you're saying now: without the resistance created by the high frequency the current has no reason to jump to another coil.

Hey Zoob. Did you post and then delete? Curious to what's on your mind concerning this.

Yeah, I posted. For some reason I couldn't see it either. I can see it now that you posted, though. Are you showing post #31?
