"2 or so hours of record time on a charge. That doesn’t seem sufficient." I'm not sure why the blackbox style of camera hasn't caught on more. (like eg http://www.rideye.com/ http://www.rideye.com/, but I'm sure there are others). My rides are commonly 100miles plus at a time - slowly - and often overnight. Not only is that too long for the camera at decent resolution, it's too long for batteries; last time I tried that, a GoPro with a 32Gb card that might've taken 8h of video died after 4h. A 5 min rolling window of decent resolution footage is all I want for crashes or highlights. But more than this, it'd be nice to have some standardisation on bike accessories running off a single power bus, not their individual batteries. My dynamo gear is great (I use a SON hub, Edelux 2, and a Secula rear) but why was this not semi-standard; I'm in northern europe and lights are needed most of the year. And once the cabling is there, why aren't bike gadgets aimed at bus power rather than more and more batteries?
