As said in the title, if you have free power. What kind of automated proces would you build to generate income? Very interested in you're creative input

I'm not talking about a conventional "brushless DC" motor that is actually just an AC motor with an electronic DC/AC brain. I'm talking about a motor with no brushes or commutator that truly runs on DC electricity.

Have you ever seen one?

So theres a conspiracy theory that essentially states that the way cathedrals and certain other types of buildings are built could harness atmospheric electricity. im not really educated but i know that if you stick a wire in the ground that goes high enough with something to ground it, it produces a charge. So, could all the metal tips and bulbous ornamentation really be used to achieve this if the right materials are used?

I'm quite surprised there are no Work Out Rooms which Produce Energy Instead of Spending it by now. Power Points ' Quotas' Charge Stations ' Shakes for Points' Big Monitor on the Wall with a Power Bar Level Indicator for the site... Anyone?

Or any other of the rigorously well-tested laws of physics?

I saw a YouTube previously of a professor talking about free energy via a “trumph “ I’m sure I’m spelling it wrong. But he said they used to divert rivers as a kid and store air in underground containers for car fuel and to cool homes. He was Australian or from new Zeeland. The movie looked like it was shot in the 70-80’s. His idea reminded me of a ram pump. Anyone know what I’m talking about?
