This is all very interesting, and thanks to everybody for giving me an 
education. My provider is very small as well, and spread out over a 
pretty large area (i'm in amador county in the mother lode). I don't 
know how many remote terminals they have, but i would think that it 
would be a lot. And if they need to be recharged every 8 hours or so, 
you'd be talking about a lot of people out in the field just to keep the 
lights on, right? And of course it takes time to recharge a battery too, 
so that makes it even worse. It seems that would be a pretty significant 
recurring cost.

How many watts does a typical remote terminal draw per subscriber?
