Vic,

While we are on the topic of Afghanistan, how about some low-tech electricity solutions for places with temperature issues...

Using Water Turbines in Alaska

If you have a steady year-round source of running water near your remote cabin or home, water generators can provide the most constant and reliable alternative power source. However, special precautions need to be taken to protect the turbine during winter freeze-up and spring break-up, and some measure must be taken to keep the system from freezing during winter.
