A portable stove includes a frusto-conical body and a grid carried within the body together with an optional cooking surface for the smaller end of the body and stands to elevate the larger end of the body to facilitate establishing an air flow into the body. By rolling a flat piece of metal that has folds on both ends until the folded ends are interlocked, the stove's body is formed. Squeezing the formed body releases it to return to a flattened configuration for storage. The components of the stove can thus be stored in a compact configuration such as in a backpack. An optional oven includes a cooking chamber within a housing. The oven rests on the body and redistributes heat from the burning fuel inside the body to the cooking chamber base, body and lid so that it bakes evenly. The housing confines the heat to the chamber for improved cooking efficiency.

What is claimed is: 1. A stove, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening; a fuel support grid carried within said frusto-conical body; a cook surface carried on said top opening, said top opening being formed to define tabs between which exhaust ga
What is claimed is: 1. A stove, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening; a fuel support grid carried within said frusto-conical body; a cook surface carried on said top opening, said top opening being formed to define tabs between which exhaust gases exit, said cook surface being carried on said tabs of said top opening; and means for elevating said frusto-conical body so as to admit a draft of air into said frusto-conical body through said bottom opening, pass through said fuel support grid and exit said top opening. 2. The stove of claim 1, wherein said frusto-conical body has an opening formed therein between said fuel support grid and said top opening, and wherein said stove further comprises a hatch covering said opening, said hatch being adapted to be lifted to insert fuel through said opening for placement onto said fuel support grid, wherein said elevating means further comprises at least three rods, and wherein said frusto-conical body has at least three holes formed therein between said fuel support grid and said bottom opening, said at least three holes being dimensions for receiving said at least three rods so that said at least three rods can be inserted partially into said at least three holes toward and into said fuel support grid whereby said at least rods extend laterally and rigidly from said frusto-conical body in order to elevate said frusto-conical body and admit said draft of air, said rods being movable inward as desired to adjust the height of the stove and thus adjust the draft and rate of combustion. 3. The stove of claim 1, wherein said cook surface has an edge and wherein a hole is formed therein near said edge for use in lifting said cook surface 16 when said cook surface is hot. 4. The stove of claim 1, further comprising a baking chamber carried by said cook surface. 5. A stove, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening; a fuel support grid carried within said frusto-conical body; a cook surface carried on said top opening, said top opening being formed to define tabs between which exhaust gases exit, said cook surface being carried on said tabs of said top opening; and means for admitting a draft of air into said frusto-conical body, through said fuel support grid and out said top opening, wherein said elevating means further comprises at least three rods, and wherein said frusto-conical body has at least three holes formed therein between said fuel support grid and said bottom opening, said at least three holes being dimensions for receiving said at least three rods so that said at least three rods can be inserted partially into said at least three holes toward and into said fuel support grid whereby said at least rods extend laterally and rigidly from said frusto-conical body in order to elevate said frusto-conical body and admit said draft of air, said rods being movable inward as desired to adjust the height of the stove and thus adjust the draft and rate of combustion. 6. The stove of claim 5, wherein said frusto-conical body includes a first series of holes near said bottom opening and below said fuel support grid, and wherein said admitting means further comprises a collar encircling said frusto-conical body near said bottom opening below said fuel support grid, said collar having a second series of holes formed therein and being rotatable so that said first and said second series of holes can be placed more or less in registration to define an air passage into said frusto-conical body below said fuel support grid. 7. The stove of claim 5, wherein said cook surface further comprises: a grilling surface; and means for elevating said grilling surface above said top opening. 8. The stove of claim 7, wherein said elevating means further comprises: support bridges crossing said top opening of said frusto-conical body; and bolts carried by and extending upwards from said support bridges to which said grilling surface can be secured. 9. The stove of claim 5, further comprising a baking chamber carried on said cook surface. 10. The stove of claim 9, further comprising: a baking housing dimensioned to hold said baking chamber therein; and a support surface having a hole formed therein dimensioned for receiving a portion of said frusto-conical body, said baking housing resting on said support surface so that said portion of said frusto-conical body extends into said baking housing. 11. The stove as recited in claim 9, wherein said baking chamber is made of copper. 12. The stove as recited in claim 9, further comprising a thermometer insertable into said baking chamber and readable outside said baking chamber. 13. The stove of claim 9, wherein said baking chamber further comprises: means for sealing said chamber; and means for adjustably positioning food vertically within said chamber. 14. The stove of claim 13, wherein said means for sealing said baking chamber includes plural latches. 15. The stove of claim 13, wherein said means for sealing said baking chamber includes a gasket. 16. The stove of claim 5, wherein said frusto-conical body has an opening formed therein between said fuel support grid and said top opening, and wherein said stove further comprises a hatch covering said opening, said hatch being adapted to be lifted to insert fuel through said opening for placement onto said fuel support grid. 17. The stove of claim 5, wherein said frusto-conical body is formed of a sheet of metal having a first edge and an opposing second edge, said first and said second edges being folded complementarily so that said folds interleave to define said frusto-conical shape but also to release said folds to open said housing when said housing is squeezed. 18. The stove of claim 5, wherein said hatch has a top edge and is secured by said top edge to said frusto-conical body by a hinge and wherein said hinge is dimensioned to allow said top edge of said hatch to hold said hatch in an opened position to allow fuel to be placed on said fuel support grid. 19. The stove as recited in claim 5, further comprising a tube for augmenting air flow admitted into said frusto-conical body.
