Educational video of one minute from the national geographic comparing the parabolic cylindrical solar to the photovoltaic.
(Of course the conclusion is that there is no comparison possible.
photovoltaics is a gadget for campsites because)

Translation:
parabolic parabolic solar is a simple but effective technology.
We focus 70 times the normal intensity of the sun on a focal point.
The steam temperature reaches 400 C in a synthetic oil.
The parabolic mirrors are made of silver and do not contain iron. The chassis is aluminum.
Beautiful image at the end on the very impressive steam jet!
Except that this vapor is not a cooling vapor of a controlled nuclear explosion ....
What I wonder is the efficiency of the system during the day and the orientation of the line of reflection for maximum performance?
Good day or evening,
Christophe
