Cathy quoted CityTV Toronto:
Canon is working on a new way to power high-tech devices that could
spell the end of traditional batteries.

Bull. The market for "traditional" batteries will remain HUGE for
generations to come - if only due to all the things sold over the past
50 years that use them! Think what market that must mean for AA
penlight batteries alone.
Fuel cells require OXYGEN to work. Not much good in any
current-generation flashlight, radio, or digicam. You can bet that
some major manufacturer(s) or importers of traditional batteries will
decide to keep that giant, very-profitable market - no matter what
small fuel cells come out.

No $4 to park! No $6 admission!
