You are correct.

I’m just wondering as everyone likes to think of what they would do in a post-collapse society…when in reality these tiny drives will probably be much less useful than the knowledge on how to create electricity. Solar or otherwise.

Solar has the issue that it’s hard to create, but there’s a plethora of ways to create and maintain electrical systems. A small wind generator could probably be easy to rig up as well.

Back when my state had power outages every other day for long periods of time, we found out what worked and what didn’t real quick.
