A camping stove add-on is a thermoelectric generator that converts thermal → electrical energy. The stove provides thermal input power Pin=150 WP_{in}=150\ \text{W}. The thermoelectric module has efficiency η=5%\eta=5\%. The device must provide at least Pout≥10 WP_{out}\ge 10\ \text{W} to charge a battery. Which modification would most directly help meet the 10 W electrical output requirement, assuming the efficiency stays the same unless stated?
