Perhaps string a long enough wire to pick up some AM broadcast station energy (remember those early 'crystal' sets we played with as kids?) - otherwise out in the bush there most likely isn't going to be enough RF power from TV, FM broadcast (or even cellular transmissions) to work with. If, by some chance you *did* cite your gear near a 'healthy' RF source - this would be a potential (forgive the EE punditry) source of DC! (It still might require a few 'tricks' to pull it off though.)

This is probably a silly idea but how about a small coil that picks up stray rf radiation, rectify it and pump up a low leakage electrolytic, this could be used in conjunction with the battery, Graham -- http://www.piclist.com hint: The PICList is archived three different ways.
