質問への直接の答えはノーです！。直射日光で調理することが可能な場所はたくさんありますが、太陽系は広大で、太陽とはほど遠い場所で、直射日光が失敗して調理します。
The direct answer to the question is No!.  While there are many locations where cooking with direct sunlight is possible however the solar system is vast and much of it is far from the sun making cooking with direct sun light unsucessful.
