Thirty Five Years of Research and Use with my Favorite Hybrid Solar/Electric Oven in Costa Rica
Abstract
Author designed, constructed, and used solar food warmer first time in the house 1979. Looking into success, various models of cookers/ovens like conventional solar oven, hybrid solar electric oven, and also including dryer, were designed and used for next 35 years. Got a patent on Solar Oven for Costa Rica in 1984 and also published a practical book on Solar oven in Spanish, in 1992 and 2004. Also with the collaboration of Solar Cookers International, based at Sacramento, USA, organised a world conference on Solar Cooking in Costa Rica in July 1994. These ovens were/are used for cooking, warming meal and other uses, when the climate permits, about 7-8 months for cooking and about 11 months per year for low temperature applications, like warming meals, pasteurizing water and drying domestic products. In this presentation only Hybrid Solar Electric Oven will be mentioned.
