3 cone solar cooker with central stand

This is a solar cooker with a solar concentration rate of about 72. This solar cooker is supported by a stand in the center. A small part of the central area of the reflector has been used for tilting purposes, but this should not affect the power of the solar cooker very much. Not more than 10% anyway. This solar cooker has an effect of 3.14 * (45*45 -15*15+10*10) = 5652 cm2 The diameter is 90 cm, but the area in the center is about (15*15-10*10)*3,15 = 125cm*3,14= 392cm2 That is not significant. More important - you can tilt it to any postion between 15 degrees and 90 degrees. The effect should be about 500 kW on a sunny day!
