Title  : A Study on Conversion of Unused dish antenna as Dish Solar Cooker 

Author Name  : V. Balasubramanian, C. Sekar 

Synopsis  : 

A parabolic concentrating type dish solar cooker of width 180cm and focal length of 90 cm is deduced from unused perforated aluminium dish antenna. The perforated surface is pasted with aluminium foil for good reflection. Its performance as a concentrating type dish solar cooker is studied with black painted aluminium vessel as absorber.  The time consumption by this type of dish solar cooker is comparable with the conventional solar concentrators made by experimentalists. Various food items are cooked in this type of dish solar cooker. The results are quite encouraging.
