1. An external combustion engine, comprising:
a source of combustion gas;
a combustion gas manifold which is in fluidic communication with said source of combustion gas;
a combustion chamber where a mixture of the combustion gas and fuel undergoes combustion to generate heat;
a cover which encloses said combustion chamber, wherein said cover has a first layer and a second layer which are spaced apart from each to form a fluidic flow path between them, and wherein said second layer contains an aperture which is in fluidic communication with said combustion gas manifold via said fluidic flow path; and
a plurality of heating blocks through which said combustion gas passes as said combustion gas flows from said combustion gas manifold to said aperture;
wherein each of said heating blocks is in thermal contact with a plurality of heat fins through which said exhaust gases pass;
wherein said combustion manifold has a plurality of inlets;
wherein each of said plurality of inlets is in fluidic communication with at least one of said plurality of heating blocks;
wherein each of said heating blocks comprises a plurality of heating tubes which heat the oxidizing agent as it flows through the heating block, and wherein each of said plurality of heating tubes is hexagonal in a cross-section taken perpendicular to said longitudinal axis; and
wherein said cover is equipped with a set of spiral vanes disposed in the fluidic flow path.
