Anyone out there using a stirling engine in industry?

Not presently and not as an engine, but I have used Stirling cycle coolers in the past. The same thermodynamic cycle that can make the Stirling engine operate with heat can make it cool to cryogenic temperatures when it driven by another motor. These are useful for localized cooling to temperatures below that of liquid nitrogen. We used them to cool infra-red detectors in laser radars and for cooling high purity germanium (HPGe) detectors which detect gamma radiation.

There is a CA energy company in conjunction with Sandia Labs in NM who are now building solar collectors and Stirling engines in the CA desert to generate electricity.

There are European built mililtary submarines that use Stirling engines. I'm sure there are other uses, but these are not exactly commonplace.

I'm interested as to your motivation for asking the question. E-mail me - kwittrup@charter.net and let me know. Stirling engine tech is used in some distributed electrical power generation applications and I know some companies who still play in this particular technology.

Stirling cycle is very much in use for creating low cryogenic temperatures. .
