Spring wound battery

I am developing the worlds first spring wound battery. The target would be for a
homes stove and hot water. Eventually I would like to adapt it to a micro electrical
grid for remote areas.
The ideas is to get humans to use their imaginations in any way they see fit to
recharge the battery by moving a ratchet type lever.
Once charged it could be
reused or sold on the open market or even donated. I see wind as the primary
way to cull the energy but any source of motion will do.
I see the discharge
being used in homes for electricity, on the farm as mechanical motion,
in the
community as donated power for use. and in industry to drive cottage industries
of any sort.
Off the grid is the goal. No centralized suppression and dominance
of resources and money.

The area that's holding me back is in the escapement
mechanism that converts the stored energy
to a rotating motion.
I need smart people to help me work out how to take a massive amount
of stored energy and release it in a controlled manner
to turn a shaft at a stead speed. Any ideas?
