Not a deep dive, but covering how the overlap of two fundamental and understandable principles, electrical induction (behind basic electricity generation), and resonance (the frequency at which an object naturally vibrates) turns into a "pregnant elephant in the room" question of "why wouldn't we use these principles to create energy much, much more efficiently??!!"
The plan is to cover this in full in a later episode, but wanted to encapsulate the basics early. The more people start thinking of this the better.

Not covered during episode, but here are a couple of relevant articles:
"Nikola Tesla's Earthquake Machine", from Forbes.
"What is Electromagnetic Induction"
