Resumen

This research seeks to contribute to reducing greenhouse gases caused by burning wood and fossil fuels with stoves. The use of solar cookers is minimal, one of the causes being their low efficiency. The objective was to reduce the risk of low efficiency of the solar cooker in the design stage, applying the Failure Mode and Effects Analysis (FMEA) to identify the actions to be taken during the design seeking to reduce the Risk Priority Number during the optimization stage. The essential element of the solar cooker is the reflector, its improvement consisted of configuring it as a truncated cone with a parabola inscribed, whose focus coincides with the centroid of the absorber (pot), managing to reduce its risk priority number from 280 to 20. © Published under licence by IOP Publishing Ltd.
