Heating by Sllar Power

Asked by Arielle Hindison · February 17, 2003 · Shabbat

Question

Rabbi In our science class we heated water to the boiling point by aiming the rays of the sun off the concave side of a highly polished mirror. I was wondering if I can warm water for coffee on Shabbat by concentrating the bounced rays of the sun off a mirror.
