While it is true the earth is not perfectly spherical (more an oblate
spheriod), it is not true that barometric pressure is that different.
Simple proof is that if you rise in altitude 13 miles anywhere on the
planet, the air becomes to 'thin' to sustain life. Yet life exists both at
the equator and the poles.

The same forces that are responsible for the 'flattening' of the land masses
also act on the water and atmosphere. The only difference between the pole
and equator are the distance from the center of mass. This results in the
200 vs. 199.5 lb of force.

But there is no way to extract energy from this difference in a continuous
cycle. Water will not 'fall' from the equator to the pole. To do so, it
would have to 'push' other water already at the pole out of the way, and
that would take exactly the same amount of energy that the 'falling' water
has.

Nor will the the higher force at the pole 'push' water 'uphill' to the
equator.

After all, just ask oneself, "Why is the water at the pole/equator at the
level it is currently at?" Because at the current levels, all the forces of
gravity and centripetal forces are in balance.
