Abstract
Disclosed are systems and methods to concentrate sunlight with inflatable enclosures to heat substances, including fluids and for cooking, and to provide concentrated sunlight for other uses. The system includes an inflatable sunlight concentrator (upper balloon), an inflatable cooking housing (bottom balloon), and a cooking container. When inflated, the upper balloon has a substantially cone-shape and concentrates sunlight towards the bottom balloon. The bottom balloon may be of various shapes and may concentrate sunlight towards the cooking space. Each balloon is less than two ounces and can be folded into a small pocket-sized package when it is deflated. The cooking space may be a thermal bag, a box, or an insulated space.
Claims17
1) An Inflatable Light Weight Solar Cooker comprising an Inflatable Upper Chamber, a Lower Chamber, and a Cooking Chamber.
17) A method of delivering thrice-concentrated sunlight into a cooking chamber comprising:
- concentrating sunlight by refraction through an Inflatable Upper Chamber Substantially Transparent Refractive Upper Lens and passing the concentrated sunlight into an Inflatable Upper Chamber,
- concentrating the sunlight a second time in the Inflatable Upper Chamber with a substantially reflective inner wall,
- passing the sunlight through a Substantially Transparent Lower Lens to concentrate the sunlight a third time by refraction, and
- delivering the thrice-concentrated sunlight into a Cooking Chamber.
