    Principle of operation and basic parameters of the solar parabolic cooker

    The reflector of a solar parabolic cooker (SPC) is axially symmetrical and shaped so its cross-section is a parabola; for that reason it has the property of bringing parallel rays of sunlight to a focus. What we have in parabolics is actually a focus spot with small but finite dimensions rather than an infinitly small focus point. If the axis...

    What requirements should satisfy the solar cooker cookware?

    Cooking and frying with the parabolic cooker are performed in ordinary commercial metal pots – usually from steel (Inox) and aluminium. Recommendable with thick thermo-bottoms. Also being used are thin-wall enameled steel pots without thermo-bottoms. Thin-wall cookware distributes the heat worse than thick-wall, so that could the food be burnt...

    Focusing of a solar parabolic cooker

    Focusing of a Solar parabolic cooker consists in targeting the reflector to the sun in such a way that the axis of the reflector is parallel to the direct sunlight. When this is fulfilled, the device is so designed, that the bright spot of the focus falls within the area of the supporting grid(supporting ring). In this sense, as synonyms are...

  • 3D-LIGHT STRUCTURE OF THE PARABOLIC SOLAR COOKER - Article

    The main idea of the article is to develop a method for determining the spatial boundaries of what one calls "focus".Solving this problem in 3D-space leads to interesting side results, such as distinguishing the geometric focus from the thermal focus.The article should be considered as first step in a new direction of research, not as solution...

I am glad you are teaching Bulgarians this wonderful technology. Now they can fall in love with solar cooked food. I think it tastes better than regular cooking. ( Sent to the Facebook-page of HoSa Solar, August 8, 2016)
