Please share your numbers with us. I'm leaning towards whichever option

In my view alternative energies are generally dependant on the weather
and natural resources of someone's location (solar, wind, bio, hydro)
where z is taking advantage of rain in his location for hydro, that
solution probably won't cut it for you.
I think the best plan for you is take stock of what weather and
natural resources your location has and pick the best plan to utilize
them. If I remember correctly, your in a semi-arid climate with good
solar and a source of wood
If you're still considering steam, maybe one DIY parabolic trough and
a model steam engine mated to a bicycle light generator to test the
idea, this wouldn't produce usable power, also wouldn't cost too much.
This idea should give a feel for the issues involved and help estimate
costs of scaling the plan up to a useable level.
I would look at the free plans for DIY ideas, I think I posted the
links here, or go to http://www.gekgasifier.com/ for kits or parts, IF
you already have a large source of free wood for fuel, this maybe your
best return on investment, you can make some usable power while
testing. Gasifiers are a time proven DIY technology with well known
issues that with care are easily avoided; pay special attention to
filtering the bio-gas, because particulates in the gas are abrasive
and will seriously reduce engine life if not removed. This issue is
well understood and with care easily avoided.
Let me know if you narrow down your choices, and I'll try to detail a
plan which you're free to ignore if it doesn't suit your needs.

Ok (good thought)
Aside from ny vast fund of inexperience and profound ignorance, I think
there's a caveat that should be applied here: I noticed with fluidynes
that scaling wasn't as straight-forward as I expected - laminar flow and
boundary layer effects seemed /much/ more significant in small scale
constructs than in the large ones; and that while some things appeared
to scale in more or less linear fashion, other things very noticeably
I don't know if the same holds true for steam (with which I have no
experience whatever), but it would seem that the same principles /might/

There's a bunch of caveats, in my view there's an efficiency thief on
every corner ready to pick your energy pocket at every turn. But just
because I can't find a way to get home-scale solar-steam to work,
doesn't mean Ulysses or someone else is going to fail also.
I'm all for the effort and feel something is learned with each try.

Agreed. What I should have suggested more directly is that testing with
the largest affordable setup might provide the more useful information.
And yes, I'm with you 100% on learning from experience. :)
