How Wave Power Works: Pelamis Wave Energy Converter

Pelamis Wave Energy Converter
This device is a of long multi-segment floating/semi-submerged cylindrical structure composed of several sections connected by hinged joints. As the waves pass, the segments move with the waves, but are resisted somewhat by hydraulics. The movement of the hydraulics pressurizes oil, which is pumped into hydraulic motors that power electric generators.
