Solar cooking is a viable alternative to gas and electricity in some aspects dependent on place and economical culture, and is environmentally sustainable, also.

To use this solar cooker, the user pulls out stacked reflectors from the bottom of the insulate globe box, then open those with one hand clockwise. User can control the angle of the reflectors (like steamer) to change the position of the focal point and the temperature inside the glass ball.
