Roger Penrose concept describes how to extract energy from black holes
The 1969 concept entails piloting a vessel near a rotating black hole, releasing a payload, and subsequently retrieving increased energy. The trick relies on "frame dragging", where a spinning mass creates a swirling effect in spacetime around it. Spacetime acts like a fluid that gets carried along by its contents, generating these persistent swirls.
