Thermal–Wind Coupled Rectification for Directional Work

Daily thermal gradients can bias fluctuating wind flows into directional mechanical work without requiring steady wind conditions.

One-Sentence Discovery

Asymmetric thermal absorption structures can rectify stochastic wind motion into net directional work by coupling airflow with diurnal temperature-driven density gradients.

The Physical Mechanism

Differential heating across vertical or channelized structures creates localized pressure and density gradients. When ambient wind interacts with these gradients, oscillatory motion becomes biased in a preferred direction, allowing cumulative work extraction over thermal cycles.

New Scientific Object

Thermo-Anemometric Rectification Coefficient (TARC): a metric describing how efficiently a system converts thermal gradients and fluctuating wind into net directional mechanical or electrical output.

Edge-of-Practice Experiment

Build two vertical membrane or channel systems—one thermally asymmetric, one symmetric. Measure net work output over multiple day–night cycles under identical wind exposure.

Binary outcome: Persistent net directional work in the asymmetric system validates rectification.

Why This Matters

Makes wind energy viable in low, variable, or chaotic wind climates by leveraging predictable thermal cycles rather than relying on steady airflow.
