$30 TESLA ROOF ANTENNAS Generate Power From Thin Air?! (No Generator Needed?)

A cheap metal rod promises power with no fuel and no bill, so I put a meter on the exact chemistry behind it. An earth battery buried in wet soil pushes real but tiny volts and microamps, the same honest yardstick I hold every rooftop antenna claim against. I trace where that electricity actually comes from, what it would take to scale it to a fridge or a CPAP machine overnight, and why the lab work behind radio-wave harvesting never shows a meter under a household load. Then there's the part no listing mentions: what a tall antenna on your roof invites from the sky, and what the electrical code says has to happen to that wire before it ever reaches your living room.
