, the work due to the presence of the flow impeding inserts increases exponentially with respect to flow. This and the fact that Fig. 6 shows a power root function behaviour with respect to flow rate suggest that the thermoelectric power enhancement brought upon by the presence of the flow impeding inserts observed will offset the work due to the pressure drop up until an upper flow rate threshold. This threshold is investigated in the following section by analyzing the net thermoelectric power output with respect to flow rate for varying panel densities
