Sunflower grill: Solar Cooker (Link: CNN.com/technology, Yanko design blog)
Sunflower Grill users can control the temperature by adjusting the angle of the reflectors to move the focal point and folded to smaller size when done being. Once reflectors face the Sun, user turns the dial, then the reflectors turn (follow) toward the sun (Current parabolic solar cooker has to be turned every 15-20 minutes). An insulated glass bowl substitutes commonly used cooking oven bag, and works 10% more efficiently than plastics.
