Aleiha'a parabolic solar cooker is a hand-made parabolic solar cooker that uses a satellite dish and discarded materials. It has a high cooking power. To make this cooker requires availability of some special materials and certain skills (cutting aluminium pieces, for instance) so may be suitable only for handymen/women. At 1:00 pm, the dish reaches 205 ºC (400 ºF), and around 2:00-3:00 pm, up to 175 ºC (350 ºF).
The cooker has succesfully cooked veggie burgers and beans. It doesn't burn food easily, as if the cooker forgets to look at the food, the sun continues to move in the sky, the focus changes it's position and the temperature in the pot descends. Considering that part of the materials used where salvaged or donated, the total cost of the cooker is of $65.
