Sunlight focused on both towers simultaneously

Today CSIRO staff had a spectacular new view out their windows, with both of our solar towers being lit up by focused sunlight at the same time. This is the first time both systems have been in operation simultaneously.

Solar Field 1, shown at left, was being run to produce SolarGas — a gaseous fuel which stores solar energy in its chemical bonds. It was achieving temperatures over 800°C and delivering around 300 kW of thermal energy to the reactor on top of the tower.

The new Solar Field 2 was being used to calibrate heliostats. As described in the previous post, a camera in the field was monitoring the focused spots of light on the target plates, checking that they were pointing accurately. This process ensures that the mirrors track the sun very precisely throughout the day.
