50. Solar Furnace The control room we were in where you steer the mirrors The laboratory with the vacuum chamber The focusing parabola The mirrors The “iris”: a pair of doors that open and close to adjust the amount of sunlight that hits the chamber
51. This is the view from the operations center. At the moment the mirrors are all stowed pointing straight forward.
52. In this example, the center 32 mirrors have just been commanded to move from standby to projecting the Sun onto the focusing parabola. As the mirrors tilt downward, the Sun shines into the window of the control center and then to the center of the parabola. The light is bright but not dangerous because we are not at any kind of focus. This entire sequence of images took place in less than 60 seconds.
