We present two novel design modifications to the basic entrochemical system which enable the generation of an entrochemical thermal battery. The inclusion of a passive mixing mechanism enables the continual disruption of the water layer that forms at the top of the saline solutions, enhancing the overall thermal gradient. Embedding of one cell’s cool side in the previous cell’s warm side allows efficient conduction of thermal energy between the two, effectively driving the additive property of the overall thermal gradient, the battery effect. We demonstrate that the passive mixing mechanism enhances performance, generating a one-cell gradient of 18.3 ± 0.3◦C …

Solar chimneys are potentially important components in energy-providing systems. These are

passive solar systems which transduce solar irradiance to airflow. The airflow, in turn, can be transformed

into electricity. While the ability of the solar chimney to create airflow has been examined in a number of

different studies, little attention has been focused on improving the performance of the solar collector. In

principle, increasing the thermal lift of the chimney would improve the chimney's overall airflow

production and extend the upper limit of energy production.

We examine an improvement to the solar collector design for the simple solar chimney capable …
