Direct Solar Steam Generation

A system comprising:

• a plurality of solar energy receiver pipes;
• a plurality of solar energy mirrors enabled to track the sun so that zero or more portions of the solar energy receiver pipes are illuminated by solar energy reflected from the solar energy mirrors onto the portions of the solar energy receiver pipes;
• and
• wherein the solar energy receiver pipes are constructed of a thickness enabling repeated acid cleaning and accounting for corrosion of the solar energy receiver pipes, and with bend radii enabling passing of cleaning pigs.

A system comprising:

• a solar energy receiver comprising a section of a continuous single pipe, the section having an inlet end and an outlet end;
• a plurality of flexible members suspending the continuous single pipe from a structure;
• at least one anchor rigidly coupling one of the ends of the section to a structure, the other end of the section being flexibly coupled to the structure via the suspending;
• and
• wherein the flexible members and the anchors are arranged to enable the solar energy receiver to freely expand and contract lengthwise.
