Practical Solar Power for Travelers?
kalido asks: "When travelling with gadgets it can be a pain to keep the power flowing, especially in remote locations. Are there any practical methods to recharge batteries and devices when on the go? A bit of googling turns up the PowerFilm, PowerFlex and SolarRoll flexible solar panels. But I haven't seen any reviews anywhere. Have any of you used these or similar devices and how easy is it to use if attached to a pack, bike, jacket, etc.?"
What devices are you going to be needing? I generally find that when I am going to a place that doesnt have power - dont bring anything that requires it. If you say GPS - bring extra batteries, unless your going for very long time.
Also - please dont say cell phone. If you are far enough to not have power - you problably wont have cell signarl.

Have you considered a hand crank charger such as this? It was the first google link for me, and I am sure plenty more exist. Depending on how much power you need, I would prefer a model that uses a foot pedal.... or recumbent bike for that matter.
Unfortunately the panel that Ken Kifer used isn't available anymore, but his page might be of use to you in putting together a system.
