Yes, there are several industrial applications that use a solar concentrator to drive a turbine engine or a Stirling engine.

I'm not sure it's a viable way to produce electricity on a small scale because:

- high thermodynamic efficiency requires high temperature difference

- photovoltaic panels are mass-produced and increasingly efficient

Personally, I think small scale concentrated solar power is most useful for applications that require direct heat (cooking, desalination, foundries).

In these cases, photovoltaics have a lower efficiency and a shorter lifetime.
