Method of implementation: Create convex lens、 design lens holder、 design thermo box、 assemble the parts and complete the product.
Princples of operation: when the cooker is located outdoor、 it should be adjusted in such a way that the convex lens turn towards the sun. In that direction、 the total solar energy will concentrate in the focus of convex lens. The thermo box has an aluminum thermal panel in the bottom、 located immediately in the focus of the convex lens. At that time、 the total solar energy will be absorbed by the aluminium panel、 increasing the heat energy of the aluminium panel、 which will transmit to the aluminium pot and cook food.
