That shit makes it really god damned hard to clean windows :@

One thing I read is that for smooth motion you should aim to have a shutter speed of half the time between frames. So, if you're shooting at 24 frames per second you use 1/48th (1/50th is close enough) shutter, and if you're shooting 1 frame per minute, you use a 30 second shutter speed. It results in nice motion blur without things looking too smeared.
Obviously 720 exposures of 30 seconds (for 12 hours of real time) is gonna be pretty hard on the camera battery.
Yeah, I've been looking into the best way to make things as smooth as possible whilst not over/under exposing.
I've bought an AC adapter for my Ixus. Been looking for one for my K200D that is a reasonable price, not managed to yet.
I can get quite a lot. Bought some Uniross Hybrios a bit back that are bloody great. Fairly certain I managed over 4000 frames on a single set. (Just shooting JPEG)
Having an AC adapter isn't going to be too much use outside the house anyway!
