SUMMARY

The discussion centers on the feasibility of capturing the energy generated by auroras through electromagnetic fields. Participants explore the concept of particles traveling along the Earth's magnetic field and ionizing the atmosphere. They question the potential for energy capture in the absence of an atmosphere and emphasize the economic viability of such endeavors. Ultimately, the consensus is that while energy capture from consistent natural phenomena is plausible, the transient nature of auroras makes economic justification unlikely.

PREREQUISITES

Could there be a way to capture the energies that create an aurora using an electromagnetic field? It seems as if the particles travel down the Earth's magnetic field like a funnel - which then ionizes the atmosphere.

What if there was no atmosphere to react with? Where would the energies go, and is there a way to 'capture' and store the electrical potential?

One can "capture" energy from most any phenomenon, be it strong winds, rushing water, lightning, etc...
The question is whether it is economically feasible to do it. In other words, does the cost of extraction justify the end result?
In cases of reasonably consistent phenomena it is looked at and considered; for temporary phenomena the answer is almost always no.
