<p>The solar cooker functions both as a grill and as an oven, the latter being circular with reflective vertical walls and a black absorbent bottom. There can also be a cylindro-parabolic reflector, situated behind the glazed oven cover and at right angles to its plane. Cooking temperatures can be programmed using a device functioning as a sundial, and simple mathematical formulae can be used to determine the proportions between the principal dimensions.</p> |
