Can't see that one being solved..... well, what with recent breakthroughs in nanotechnology you never know. If you want something that works, rain or shine, then we need to combine the past with the present, and shrink it. A small waterwheel attached to the side of your camera could generate plenty of power during a rainstorm; if the weather was dull and overcast then the sails of the wheel could catch the slightest breeze, and generate plenty of power that way. And of course in f/16 conditions the bright sunshine would be collected on the sails which are, of couse, fitted with teeny-weeny, but immensely efficient, solar panels. Finally, if the weather simply won't play ball, then you can use gravity. The centre of your camera must include a yo-yo mechanism and some sort of power exchange device, like a dynamo, attached to the yo-yo spindle to capture Newton's favourite apple plucker. Sadly, though, that emergency back-up won't work in outer space. -- Cheers, Bob mailto:[EMAIL PROTECTED]
