Pressure Differential

Submerged or semi-submerged devices that use differences in pressure to generate electricity.

Pressure differential devices use differences in pressure to generate electricity and can be either submerged or semi-submerged. Bulge wave devices, for example, are typically water-filled rubber tubes that use pressure variations created by waves to drive a turbine. Similarly, submerged point absorbers use the pressure difference between wave crests and troughs to drive a turbine.
