Ocean Pressure - Electricity Generation

interesting

Heard at school, how hydro electric dams are constructed, throwing water from great height directly on to turbines to generate power electro-statically.  So the main component is pressure.

Heard 1 atmosphere (ATA) is 14.5 (psi) pounds weight of air per sq inch at sea level. And every 33 ft, pressure increases by 1 ATA. Seems human can bear 3-4 ATA so max 100ft depth wow interesting.

Sounds like water dropped from 1x33 ft height can generate 0.43x33 = 14.19 psi weight.  (not considering amount of water/sec)
Appears reasonable to assume ability to generate large amounts of electricity at mere depths of 80 - 100 ft of water in lakes or oceans.

Not sure how useful this formula is energy = pressure * volume in this scenario

Well I am not physicist
