===Heat transfer===
The sunlight bounces off the mirrors and is directed to a central tube filled with [[synthetic oil]], which heats to over {{convert|400|C|F|sigfig=2}}. The reflected light focused at the central tube is 71 to 80&nbsp;times more intense than the ordinary sunlight. The synthetic oil transfers its heat to water, which boils and drives the [[Rankine cycle]] steam turbine,<ref name=solel>{{cite web
