I think a turbine would have to be very precisely made - probably beyond the capability of home-made tech. Also, I think it would have to run at a very high speed to make any usable power, necessitating a gearbox to reduce rpm to match that of the alternator.
IMO, an easier system (and more likely to work), would be to use a positive-displacement engine (a small lawnmower, weedeater, or chainsaw engine) and convert it for use with steam. The rpm ranges match the alternator more closely and most of the precision parts are already machined.
Here's an example of a converted two-stroke engine. Of course this would need much more refinement.
