we heard that MTI Micro was working with "an elusive Japanese developer or digicams" to get its Mobion fuel cell tech into actual products. Given this Canon Fuel Cell DSLR patent, it looks like we can no-so elusively safely say where the camera is being developed. The patent itself is straight up enough: "The present invention related to an electronic equipment system having fuel cells, and more particularly, to a camera system in which fuel cells are provided to a camera body and a connection device connected to the camera body." It looks as though the fuel cells will power the entire camera system, including flashes and other motors, complete with a separate power management system, sort of like having your own mini generator. As for when this system will be available, no word.
