It is my layman's understanding that a multi-stage steam turbine approaches unity. I think that's a good goal for the multi-stage freon turbine for the Organic Rankine Cycle system that will change the world. With solar energy as the input to the system, losing 10% efficiency won't really matter that much. Just add a 10% bigger heat collector. You have a whole roof to play with.
Photovoltaic is one thing, concentrated solar is very different. You'd need one hell of a large roof and clear, clear skies to make any use of it. But hey, I'm all for turbines at home. What happened to that Jag prototype anyway?

But you are still going to lose 10%.. just 10% from a larger collector
Yeah, well just up size it 10%. Big deal. We're changing the world here. Put up a panel 10M x 3M on the roof, that's 30M^2, or, roughly, 30KW of power coming in. ASSume a bunch of losses. OK, that's still 15KW of energy to play with. Dump that into the freon (ORC) turbine, loss here and there, and you should not have difficulty getting 5KW or better out of the system, which should run the house just fine, plus provide enough juice for your plug in electric truck conversion. Hey, put a heat exchanger in the house and capture that heat as well, resulting in a cool house in the summer time. Fer free.
Wait.. you're suggesting using a solar collector to heat freon (or, rather, refrigerant, since "Freon" is a DuPont trade name for CFCs) and using the resultant gas to drive a turbine, then condensing it and sending it back through the solar collector? How would you get it to condense?
