Also known as a central receiver solar power plant, a type
of concentrating collector
system that employs a field of large mirrors that follow the Sun's path
across the sky. The mirrors concentrate sunlight onto a receiver on top
of a high tower. A computer keeps the mirrors aligned so the reflected rays
of the Sun are always aimed at the receiver, where temperatures well above
1000°C can be reached. High-pressure steam is generated to produce electricity.
