I was emailed by Greg P. the following regarding use of the equipment above.

"Photo number 20 - the "sci-fi" picture is actually an electrical switch.

These types of switches are used in high voltage switchyards just like you
use a light switch on your wall. They are closed to connect a transformer
or circuit breaker to the overhead grid lines, and are opened to disconnect
the grid from the circuit breaker or transformer.

In the picture, the switch is closed."

Thanks Greg.
