Solar powered high pressure steam generator

An internal receiver for transferring concentrated solar energy to a working fluid, the receiver comprising:

• a circular aperture through which the concentrated solar energy enters the receiver;
• a cavity with walls extending behind the aperture, the cavity having a deep pointed shape and being designed to maximize blackness in a cavity of minimum length;
• a pressure vessel surrounding the cavity, the pressure vessel forming a cylinder around the cavity and being attached thereto, the pressure vessel having a circular rear surface;
• a working fluid input line for injecting the working fluid into the pressure vessel where the concentrated solar energy absorbed by the walls of the cavity can be transferred as heat energy to the working fluid;
• a working fluid output line for carrying heated working fluid from the pressure vessel to a load the fluid input line comprises a single fluid input line coupled to the center of the pressure vessel's circular rear surface and the fluid output line comprises a pair of fluid output lines coupled to the perimeter of the circular rear surface, the pair of fluid output lines insuring that the cavity wall remains wet as the receiver approaches a horizontal position.

A cradle for a solar concentrator dish, the cradle permitting the dish to move around a polar axis and a declination axis, the cradle comprised of twelve members, the members each having a first and a second end, the twelve members forming a first, second, and third tetrahedron, each tetrahedron having six edges and four vertices, the first tetrahedron comprising the first, second, third, fourth, fifth, and sixth members and the first tetrahedron's vertices comprising:

• a first vertex comprising the first ends of the first, second, and third members;
• a second vertex comprising the second ends of the second member, the first end of the fourth member, and the first end of the sixth member;
• a third vertex comprising the second end of the third member, the second end of the fifth member, and the second end of the sixth member;
• and
• a fourth vertex comprising the second end of the first member, the first end of the fifth member, and the second end of the fourth member;
• the second tetrahedron comprising the fourth, fifth, sixth, seventh, eighth, and ninth members and the second tetrahedron's vertices comprising:
• a first vertex comprising the first ends of the fourth, sixth, and seventh members;
• a second vertex comprising the first ends of the fifth and ninth members and the second end of the fourth member;
• a third vertex comprising the second end of the fifth and sixth members and the first end of the eighth member;
• and
• a fourth vertex comprising the second ends of the seventh, eighth, and ninth members;
• the third tetrahedron comprising the sixth, seventh, eighth, tenth, eleventh, and twelfth members and the third tetrahedron's vertices comprising:
• a first vertex comprising the first ends of the sixth, seventh and tenth members;
• a second vertex comprising the second end of the sixth member and the first ends of the eighth and eleventh members;
• a third vertex comprising the second ends of the seventh and eighth members and the first end of the twelfth member;
• and
• a fourth vertex comprising the second ends of the tenth, eleventh, and twelfth members.
