Negentropic Thermal Gradients: Experimental Evidence of Entropy Decrease Driven by Active Heat Flux

The Second Law of Thermodynamics asserts that entropy in isolated systemstends toward maximum, with heat transfer representing dissipative energy dispersion. We present experimental evidence challenging this axiom through systematicobservations of entropy-decreasing processes driven by active thermal gradients. Using controlled experiments, we demonstrate: (1) spontaneous organization of matteragainst gravitational potential toward heat sources (negentropy), (2) instantaneouscessation of thermodynamic work (<0.2s) upon gradient removal despite thermalstate retention at 100.8°C, demonstrating that work depends on gradient ∇T ratherthan temperature T, and (3) vapor phase transitions at 30.1°C (69.9°C below standard boiling point), indicating gradient-driven extraction violates equilibrium thermodynamics. Analysis reveals tripartite energy dynamics where thermal gradientsstore energy in eld structure (Ugradient), enabling mechanical work through internalenergy reservoirs independent of bulk temperature. We propose that heat ux functions as an organizing attractive force rather than purely dispersive energy, with thethermal gradient generating mechanical work that locally decreases entropy. Thesendings suggest fundamental revision of the Second Law to account for gradientdominated non-equilibrium regimes where |∇T| exceeds critical thresholds.热力学第二定律断言，孤立系统的熵往往趋于极大值，而热传递代表着耗散性的能量弥散。我们通过对由主动热梯度驱动的熵减过程开展系统性观测，提供了挑战这一公理的实验证据。利用可控实验，我们证实了以下三点：(1) 物质自发克服重力势能向热源聚集（负熵，negentropy）；(2) 即便热状态维持在100.8℃，移除温度梯度后热力学功会瞬时终止（耗时不足0.2秒），证明热力学功取决于温度梯度∇T而非温度T本身；(3) 在30.1℃（较标准沸点低69.9℃）下发生气相相变，表明由梯度驱动的能量提取违背了平衡态热力学规律。分析结果揭示了三元能量动力学机制：热梯度将能量存储于场结构（U_gradient）中，可通过与整体温度无关的内能储库产生机械功。我们提出，热流并非仅为弥散性的能量，而是可作为一种具有组织性的吸引力；热梯度可产生机械功，从而在局部降低系统熵值。上述研究发现表明，需对热力学第二定律进行根本性修正，以适配温度梯度占主导的非平衡态体系——当|∇T|超过临界阈值时，该体系的热力学行为将偏离经典规律。
