<p>A solar heating oven comprises a chamber with triangular sides, a transparent cover and a double glazed false base above a black base. The design ensures relatively high thermal efficiency and cooking rates due to use of greenhouse effects trapped above and below the level of the food being cooked. The walls can have reflective surfaces to further enhance the heating of the central space. They are pref. made of insulating material.</p> |
