Fischetti: Right, if you think about a long trough that reflects sunlight, it concentrates the sunlight along a pipe that runs parallel to the long trough and concentrate [s] the sunlight like a magnifying glass, [which] heats the fluid inside this pipe really hot, so the hot fluid circulates out to a
somewhat traditional power plant where it's allowed to expand into
high pressure gas that turns a turbine which generates
electricity.
