Celestial Solar Tower

This is the new solar thermal power plant outside Seville in southern Spain. The tower is surrounded by a field of 600 solar reflectors that focuses the light into a receiver at the top of the tower and converts the concentrated solar energy into steam. The steam is stored and then used to drive turbines that produce enough electricity for 6000 homes. One can only wonder what aliens would make of this tower bathed in what could only be perceived as a celestial light.
