“You have to KEEP MOVING the magnets!”
Or the copper coils. That being the case, what we do is surround the entire Earth with copper coils in space. The Earth is constantly rotating, and is magnetized, so we will produce electricity!! So simple.. (Yes, I’m joking..).
So a generator is also another name for an electric brake. A car alternator at full output is a 5 horsepower brake. Your planetary generator will not only make free power, but also make the work week longer.
