Most of the power produced by microturbines is in the shaft, not as a result of thrust. Smaller engines all the way from micros up to PT-6 engines and larger use the shaft output as the primary method of producing power through the rotation of a propeller (turboprops). This is not to say the thrust is useless, just it doesn't represent the majority of the power produced by the engine. If you're looking for a thrust-based turbine, it will likely need to be far larger and probably impractical.
