| Abstract: |
An inflatable solar oven is comprised of two sheets of flexible material which are sealed at their edges to form an enclosure. The top sheet is clear and the bottom sheet has a reflective layer. The two sheets can be inflated to form a spherical enclosure by passing air through an edge opening that is also large enough to access a water or food holding receptacle which can be placed with the inflated enclosure. Extended portions of the sheets that form the opening can be rolled up to form a closure for it. The inflated enclosure can be secured to the ground in an appropriate position to receive the sun's rays which pass through the clear sheet and reflect from the bottom sheet to heat the receptacle therein.

What is claimed is:
1. A method for heating food or water using solar energy comprising the steps of:
- forming an envelope body from first and second sheets of flexible material, said first sheet comprising clear plastic material and said second sheet comprising plastic material having a reflective coating, said sheets being generally circular in shape, with radially extending and overlapping stem portions and being sealed along their peripheral edges including a portion of said stem portions which thereby form a temporary access opening into said envelope body;
- inflating said envelope body with air to form a generally spherical shape so that said second reflective sheet forms a concave surface within said body that directs solar energy toward the central space of the inflated body;
- placing a container with food or water through said access opening formed by said stem portions and thereafter folding said stem portions to close said opening and thereby retain air within said body;
- positioning said inflated body so that solar rays are reflected from said reflective layer of said second sheet onto said food or water container within said body; and
- securing said inflated body in its selected position by to anchoring means in the surrounding ground area.
