Modern Steam Engin

May I take someone's time to inform me about the availability of modern steam engins designed for generators?

Thank you.

You can try Skinner in Erie, Pa. They may still be building reciprocating engines for export. I doubt that they have much of a selection of smaller engines though.

And, as I already suggested, many "experimental", or one off, high speed engines have been built using the Tiny Power M castings as a start.

OR you can always build a roller/ball bearinged, enclosed crank, forced oil, poppet valved, uni-flow from scratch. If you design it properly, you'll have something as good as anything currently in production.
