(a) Current-voltage plot (closed squares) and power-voltage plot (closed circles) of the BST/Ni tube measured by introducing hot-water of 95°C and cold-water of 10°C at Fcw and Fhw of 20 L/min. The linear fit and the quadratic fit to each data are also shown by the solid lines. (b) Vop of the BST/Ni tube measured as a function of Thw. Note that Tcw is fixed at 10°C and Fcw and Fhw is both fixed at 20 L/min.
