The only small turbine I saw is for the lighting of the steam locomotive ... turbine made a little like side channel pump: very bad performance ... acceptable because in a locomotive of a few thousand horses we do not care about the consomation of the lighting turbine
I saw a microturbine (well, a few tens of kW anyway) on Schnell cogeneration engines. Something crazy, at something like 50 rpm, to wring out the last watts, on the exhaust, after the turbo (it seems to me). This allows them to "scrape" around 000 kW electric on 15 kW electric groups (Scania 250-cylinder base).
This turbine is about as big as a blender Moulinex (or other brand)!
On the Schnell website: http://www.schnellmotor.de/sm/leistunge ... nenten.php
go to "Leistungen" then "Komponenten" and look at "Gasturbine".
I do not know the price of the jewel ...
