After concentrated sunlight heats the unit to several hundred degrees, it can be stored in a heat retention basket, which is then opened at night to provide several hours of safe, smoke-free heat until the family goes to bed. It was designed for Tibetan nomads who needed something portable, but heavier parabolic solar cookers could also be used by Afghans for night time heating.
