Abstract:
1. A portable device for the production of electrical energy, comprising a matrix of one or more conversion modules, operating in series or in parallel, wherein each of the conversion modules comprises: a combustion chamber having an outer surface defining a substantially spherical shape and made of material that is able to withstand high temperatures, an external lining having a selective radiation emissivity in a predetermined wavelength on the outer surface of the combustion chamber, means for supplying a combustion support substance into the combustion chamber, means for the removal of gaseous combustion products, means for igniting the combustion reaction, an injection device connected to said combustion chamber by means of an injection conduit to inject the combustion support substance into the combustion chamber, a controller for controlling injection frequency of the combustion support substance into the combustion chamber to thereby control power generated by the combustion chamber, a conversion chamber within which sub-atmospheric pressure conditions are maintained, wherein the conversion chamber includes: the combustion chamber is enclosed within the conversion chamber and is positioned in correspondence with the focus region defined by the elliptical wall of said ellipsoid, wherein radiation emitted by the combustion chamber and reflected by the energy conversion means on the interior surface of the planar wall and radiation emitted by the combustion chamber and reflected by the radiation reflective inner surface of the elliptical wall are concentrated on the outer surface of the combustion chamber for re-absorption by the external lining thereof.
