Retrocausal turbines (also known as CTC dynamos or chronological loop generators) manipulate time to recycle entropy, resulting in a power source. They exploit Closed Timelike Curves (CTCs) to recycle energy, effectively reversing the flow of entropy within a localized system.
Unlike standard engines which burn fuel to create heat (increasing entropy), a retrocausal turbine operates by sending its own waste products back in time to be used as fuel.
The engine relies on the Novikov Self-Consistency Principle, which ensures that time travel does not create paradoxes.
- The engine consumes high-energy fuel (State A) to produce work, resulting in low-energy waste/ash (State B).
- The waste (State B) is fed into a microscopic wormhole or CTC and sent back to a point before the reaction occurred.
- During the transit through the CTC, a localized Entropy Inversion Field creates a reverse thermodynamic trajectory. The waste re-assembles into fuel (State A) just as it arrives in the past.
- The "recycled" fuel is fed into the engine.
From the perspective of an outside observer, the engine appears to run indefinitely without any fuel input, emitting zero waste heat. It is a closed loop of causal interactions where the "effect" (waste) becomes the "cause" (fuel).
Causality drag[]
While theoretically perfect, these engines suffer from causality drag. The universe resists perfect efficiency. Over eons, quantum fluctuations leak into the closed loop, introducing informational noise. If not vented, this noise accumulates until the CTC destabilizes, causing a chronoclastic detonation—an explosion where the engine ages billions of years in a nanosecond, instantly turning to dust.
