18 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. How it works Heave Side view Power module Hydraulic ram The motion caused by a wave swell is resisted by hydraulic rams Heaving and swaying Sway Top view Hydraulic ram Power module Power conversion module SwayHeave Joints on the opposite side of the power module allow for a perpendicular sway motion Hydraulic rams Motor Gen- erator Collection chamber Hydraulic rams pump high-pressure fluid into chambers that feed the fluid to a motor. The motor drives a generator to create electricity. Converting the Motion
