The question, scope, and sources behind this Registry record.
What is the maximum thermodynamic efficiency η achievable by any heat engine operating between a hot reservoir at T_h and a cold reservoir at T_c?
Current frontiers derived from accepted Claims.
Assertions tied to evidence, attribution, and review.
The frontier as it changed over time.
Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
