I woke up the other day with this on my mind (and, yes, this is what I get for watching a Tesla documentary before I fall asleep):
Coriolis force powers the Foucault’s Pendulum and makes the weather. Someday, we’ll make our energy with it. I think this may be part of what Tesla was thinking about.
I’m not the only one thinking about this by far. That seems to make it more likely that we’ll figure out how to harness this energy and put it work for us.
