Put a bike chain on the "pull rod" and put the chain around a
freewheel sprocket on a flywheel (think exercise machine flywheel)
with magnets on the flywheel and an alternator stator. If you want
more ballanced power put 2 chains on with 2 freewheels, one on the up
stroke and one on the downstroke. The "free" end of the chain is
restrained and returned by a light doorspring.

Been done. You can judge the efficiency of such a system by the number
in use today.

I'm thinking buy up a bunch of those shaker flashlights, duct tape them
to the sucker rod, and wire them up to a battery farm and then use an
inverter to get 110 V ac for the beer fridge.
That should getter done.

1 stroke per second isn't gonna' generate enough to keep one beer cold.

But once you have the motion back to rotary, it is a simple job to
speed up the driven pulley/gear/whateveer.
We used a "WinCharger" back in the 30s and 40s to keep the car battery
that ran the house radio charged. That was before the REA came
through. I think that company, or similar , are still in business.
