Type: 

Parabolic cooker, concentration

Description: 

Hand-made parabolic solar cooker that uses a satellite dish and discarded materials. It has a high cooking power. The making of this cooker requires availability of some especial materials and a hard work (cutting aluminium pieces, for instance) so may be suitable only for handymen/women.

Dimensions: 

6 ft diameter

Area AP: 

36 sq. ft.

Weight: 
Materials: 

Salvaged satellite dish (1,8 m (6 ft) in diameter)
Discarded sheet aluminum cut into triangular pieces
Conduit piping
A bike rim
Aluminum rivets and washers

Temperatures: 

At 1:00 pm, the dish reaches 205 ºC (400 ºF), and around 2:00-3:00 pm, up to 175 ºC (350 ºF).

Comments: 

The cooker has succesfully cooked veggie burgers and beans. The cooker 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 dolars.
