I imagine we might see some microturbines and micro-generators with a fixed power output and much better efficiency (esp with cogen) i.e. ~%60 fuel to electric. I don't know if this is gonna make it into production. As an aside, it is hard to get %93 mechanical to electrical efficiency in a hydraulic pump at 800,000 rpm
