Power modules
Pelamis wave energy converter
The Pelamis machine, 492 feet long with an
11.5-foot diameter, is composed of three power
conversion modules connected by weighted tubes.

Collection chamber
Joints on the opposite side of the power module
allow for a perpendicular sway motion
Hydraulic rams pump high-pressure fluid into
chambers that feed the fluid to a motor. The
motor drives a generator to create electricity.
