Abstract

Warming meal at educational centers for students is done with microwave ovens consuming high energy. Conventional hot box solar ovens can warm meal using free, abundant, and clean Solar energy, during most of the time in many places in Costa Rica. For the rest of the periods, Microwave Ovens, can be used if required. In order to reduce the cost of heating meal, no solar ovens are used, and the lunch box with meal is just kept in Sun. Different conventional and disposable pots are studied which can be used also in Microwave ovens. Due to pandemic period experiments have been done at authors house for measuring oven, meal temperature with solar radiation and with different pots. The results are encouraging After two years of COVID, this year the classes are planned in live and again the real heating of lunch will be done. We plan to promote the concept and see the acceptance by the students
