Flow of electrical current through water is expected to increase water temperature. We passed low-frequency alternating electric current through distilled, deionized water using platinum electrodes and found, instead, a diminution of temperature. The diminution was observed using both an infrared camera and a spectroradiometer, the latter allowing us to obtain spectral information. The diminished temperature persisted for at least half an hour following cessation of the current flow. Diminished radiant energy implies reduced charge displacements, which in turn implies increased structural order. Hence, the passage of charge into water appears to increase the water structure.
电流通过水时，水温预计会升高。我们使用铂电极让低频交流电通过蒸馏水和去离子水，然而却发现温度降低了。我们使用红外热像仪和光谱辐射计观察到了这种温度降低的现象，后者使我们能够获取光谱信息。在电流停止后，温度降低的现象持续了至少半小时。辐射能减少意味着电荷位移减少，这反过来又意味着结构有序性增加。因此，电荷进入水中似乎会增加水的结构。
