I have built parabolic solar ovens before and they work quite well. Easy to build and quick to heat up. They are in use around the globe. I once built
a Parabolic solar oven out of card board and aluminum foil with the infamous scientist, Professor Harry Stubbs, ( A.K.A. Hal Clement, the science
fiction author) We cooked hot dogs, (yummy sun dogs), with it long ago.
