CHEAPEST SOLAR HEATED IN THE WORLD
Here we have a design for the cheapest solar water heater in the world. It consists of a tank in the form of a right angle triangle with 45° angle. The walls are properly insulated. On the longest inclined side we place a black coated box contains a core of a car radiator, also coated with matt black paint the bottom end of the coil is attached to the tank to allow cold water to travel to the coil. The upper end is attached to the tank. This setup provides a convection circle. This heater is so simple and cheap to build.
فرن شمسي داخل المطبخ إهداء لأهل غزة
يمكن الآن إدخال الشمس إلى داخل المطبخ، إما خلال شبّاك في اتجاه الشمس أو من فتحة في سقف المطبخ المعرض للشمس. وذلك باستخدام المخروط العاكس وفرن لتجميع أشعة الشمس المركزة باستخدام المخروط العاكس وهو يمتاز بهذه الخاصية، وبهذه الطريقة يمكن الطهي على الشمس مباشرة داخل المطبخ وهذا النظام يعطي حرارة تبلغ 200 درجة مئوية وطاقة تصل إلى 2000 وات
It is feasible now to bring solar energy inside the kitchen, through a window that faces the sun or through an opening in the kitchen roof that is exposed to sun. This is done by using a reflecting cone and a stove to collect sun rays which has been concentrated by the reflecting cone. This method enables us to use solar energy to cook our food directly inside the kitchen. The system is capable of giving heat that reaches 200 C° and gives and energy of 2000 watts.
