Cheap energy sources for electronics during touring with low amount of sun energy? My goal is to find a cheap energy sources for touring. 

I cannot use solar all the time so I am planning to get Reelights outlined here, for lights, because they are cheaper than installing a hub generator. But the next problem is my laptop because it needs much more energy and I don't have much solar radiation at my latitude. I included the description about solar panel installation because I may need to use it with other energy sources which I am not aware of, perhaps gas, oil or something like that but they are expensive. So to the question: 

Which cheap energy sources would you use during touring with low amount of sun energy?

One possible implementation to store energy


  The ten-watt solar panel (which weighs
  about a pound) lies on top of my
  panniers on the back of the bicycle (I
  carry my tent and sleeping bags in the
  front bags). As I ride, mostly in the
  sun, the panel produces current which
  runs through 12 5.7AH nicad cells,
  charging them during the day. After I
  stop for the night, I unplug the
  panel, and use the same plug to
  connect the battery to the computer
  via a Targus auto/air adapter.
  
  This setup requires me to carry the
  computer, an AC charger and the Targus
  DC charger, the solar panel, nicad
  cells and connector cord, a
  multimeter, and various nylon and
  plastic bags plus the computer case,
  with a total weight of seven pounds or
  less. (source)


Suggestions, some of which may be a solution


hub dynamo recommendations here for lighting
solar panels for electronics projects
moz suggests here to carry a solar panel but not diamond-framed
Amon suggests here a particularly interesting home-brew stuff that may lead to some kind of solution but with USB.
Darkcanuck outlines the situation with different choices here: sun, AA/etc charger and dynamo charger.
solar-powered Laptop during touring, more here.
Assuming you add the robust stand you were talking about here it should be possible to pedal the bike on the stand. Even pedalling gently will give you 50-100W of mechanical power that you can use to spin a small generator. I suggest looking for a dead RC toy and using the motor from that, since they often use that level of power. Ideally drive it from the chain rather than the tyre, but focus on making it work to start with. A little work on voltage conversion should give you enough power to charge the laptop fairly quickly, and with a little work you could even use it while pedalling.

Otherwise a hub dyno. A decent bottle dyno will not be much cheaper but will need more maintenance.
