From what I've gathered from youtube you'll usually need to create a height difference of some sort by damning up a bit of a stream, then have the overflow go through a pipe that's a sheer drop down onto an impeller attached to an electric motor (bonus points if it's recycled from something like a washing machine).
Then from that motor it's on to battery chargers etc....
