China just finished building some but it's a dead end technology.

It first lost to PV for daylight generation, then it fell back on storing the heat for use generating after sunset but cheap batteries made that obsolete too.

It's not even competitive to use mirrors to get sunlight to heat water. PV is cheaper for that.
