thanks rj and zero for the input. That igo looks good also but I'm leary of the recharging capacity available with two AAs. The Edge 305 batteries are rated just under 1 amp hour (1000 mah) , so how much of a charge can I get out of a couple of AAs before they deplete to the point of zilch charging? Zero- think I would like to be able to just take along a few AA Alkaline to use for recharging. Can get them anywhere and cheap.

Yes, I would rather set up a solar system that really works. Perhaps 200+mah @ 6 vdc (rated), I'm not adverse to hanging out for a day on tour to let things charge up. Normally when out in the wilderness there isn't cell phone service so that's not a big consideration, it's off anyway.

How about solar cells on a bike helmet? Several small mah 6V sections set up in parallel so if one section is shaded the others will produce? I'm actually just kidding (about half kidding) but it would be cool, or nerdy. Still need some open area for ventilation. Heck, if they get $120 for a regular bike helmet we ought to be able to get big bucks for a solar helmet!
