bizzare comment. I don't believe for a second the op decided to imply a connection, nor that any single reader would take that away from reading the comment. They were simply highlighting the relative magnitudes of power using something that us techies are likely to be familliar with, and something that is in the public conciousness recently (the power consumption of bitcoin)

Overall, I learned that the dam has an impressively high power production, nothing more.

It shows the magnitude of damage that can be caused by generating the amount of electricity used by it.
