Digital photography

My brother is looking for a little camera to take touring. He's no camera geek so a point and shoot will work fine.

A request of his which is a little trickier is that he doesn't want to take a battery charger and would like to charge the camera like it's a phone off his solar charger.

Any ideas about this? I can't seem to find anything that can do this? Bit tricky to search for.

I hear that samsung has by far the best built in WIFI / uploading interface. This would no doubt be very useful for doing stuff on the move. They also charge via usb, are well specced and are cheap.
