Sounds sort of like the concept behind bagpipes... Short high power inputs into an accumulator, while steadily drawing small amounts of power out. I can see why hydraulics make the concept easier to visualize, but I think in the end it would work better with electricity, no?

I've been tossing around automotive hydraulic accumulator ideas for years and I keep coming up with too many problems. Maybe you can start a thread on your concept and we can hash it out fully there?
