Seems like I read someplace (online), the Brits had a parabolic trough generating plant in the Middle East (1920s??). I believe it mentioned they heated oil to generate steam (I think).

Where you are finding Evacuted tubes for 1-$4? Since summer is winding down, I am back to pursuing my solar thermal project. Incorporating ETubes I may want to consider.

Thanks
