Okay, so I’m working on making a setting for a TTRPG and am working on what to put on the North Pole area. I’m thinking a big ol’ Antartica-esc continent with a civilization of Nordic-like people that have castle-sized buildings of ice and stuff like mega-igloos reinforced with steel and stone and the works. However, the key idea I have for them is using the Aurora Borealis there for power. I heard they produce a lot of electricity and heat, so I’m toying with the idea that they have these huge spires that jutt into the sky with these huge basins filled with water and rods of metal that basically hold and store the power of the auroras. The energy from these auroras is used mainly in starting fires to create heat, creating electrical weapons, charging magnetite to have moving castles and stuff — kind of like what you’d see in an Uncharted game. Stuff like that.
In short, I just wanna know if it’s possible/feasible. Can you harness the power of an aurora?
