If you were an ant standing atop a running dynamo, you’d find that you’re surrounded by an electromagnetic field of varying intensity. Further, you’d find that the field’s intensity varies depending on how far away from the centre of the dynamo you go. If you were a smart ant, you’d recognize that you can exploit the difference in electromagnetic field intensity at different distances from the centre of the dynamo to generate some power.

The earth is a gigantic dynamo.
Yep, the basis of Tesla's free energy idea.
