and another toy-(not hooked up to anything, could also be solar powered..)-

a couple of diagrams with the basics-

they could even be solar driven-
http://en.wikipedia.org/wiki/Passive_solar
cheap versions of these (similar to einsteins refrigeration patents) can be found propane powered in RVs- probably could easily convert to solar with concrete parabolic dishes

concrete looks to be the easiest(cheapest) way to get a very big dish- maybe a little TiO ceiling paint on a very large dish. for steam it would just be a large trough instead of a dish.
I know (for whatever reasons) Afghanistan has trouble getting major water projects off the ground-these are simpler

Water is probably a lot more important than electricity is at first.

2) Sunlight energy would be nice, but you have to BUY solar panels and the return per cost should be weighed vs wind. I have been working in Afghanistan (both on the economy & on bases) since 2003 so I can attest that there is a HECK of a lot of wind everywhere I've been (except Kabul)...
3) I would STRONGLY suggest you search out "wind turbine" here on Instructables and THEN go from there. I'd guess that IF you have a "free" generator/ alternator then you could "Afghan Engineer" the rest pretty easily. This is a pretty cool one for example http://www.instructables.com/id/How-I-built-an-electricity-producing-wind-turbine/

In the above link I've found the plans for a stationary windmill, a thing you just assemble and let it catch wind from whatever direction, so it has the least number of moving parts.
Had to see if it worked so I've done this:
Stationay windmill
As it works, it can be made big, linked to a gasoline generator's pulley, and generate wind power.
Maybe this will help.
free plans
these are for generating electricity
drag windmills are lower tech but suited to water pumping (but not electrical generation)
check your local library for books on wind power
lots of good stuff on internet as well.
You're also going to need a low speed turbine as the average wind speeds are on the low side (Kabul for instance has an average of 8mph for the year charted over the past 9 years). Not really ideal for making large sums of energy.
