Canon has announced that it has developed three different sizes of hydrogen fuel cells which it hopes will start replacing traditional batteries within the next 3 years. That’s not the only thing that the Japanese camera giant is working on:

“Canon, the world’s top maker of copiers and cameras, is aggressively investing in the development of new products, keen to cultivate new growth drivers as the digital camera market slows and competition in the printer and copier markets heats up. The move is also in line with its plan to cut procurement costs by bringing more production of key parts in-house. Canon is also developing organic light-emitting diode (OLED) displays to replace the liquid crystal displays (LCD) it buys from other firms for use in its cameras and printers.”
