Many mirrors are used on the large high temperature solar plants.
The molten salt tends to eat the pipe, I wonder why?
Like this one:
A solar thermal plant in Nevada is the latest in the long list of Obama administration energy failures. The Crescent Dunes solar facility remains on the hook to repay $737 million in loan guarantees from the federal government, according to Bloomberg. Unlike solar facilities in Minnesota, which use photovoltaic (PV) panels to turn sunlight into electricity, the Crescent Dunes plant used an array of mirrors to heat a tank filled with molten salt that would then heat water to generate steam and electricity.

“Many mirrors are used on the large high temperature solar plants.”
Actually those are called “mirrors”. Solar panels are different.
