The simple answer: The Pelamis wave energy converter absorbs the energy from ocean waves and converts it into electricity. Waves make the Pelamis wiggle on the surface of the sea like a snake, and the motion at each joint is captured through a hydraulic system.
The detailed answer (from their brochure): The Pelamis is an offshore wave energy converter, typically installed 2-10km from the coast in deep water.
The Pelamis machine is made up of a number of tubes floating on the surface of the water, linked by universal joints which allow flexing in all directions. As waves pass down the length of the machine and cause the joints between these sections to bend the movement is converted into electricity via hydraulic power take-off systems housed inside each joint of the machine tubes. Hydraulic cylinders resist the wave-induced motion and pump fluid into high pressure accumulators, allowing electricity to be smooth and continuous. Each of the power take-off units are identical, and operate independently from each other with redundancy of all main components. Power is transmitted to shore using standard subsea cables.
The joints of the machine can be actively controlled to make use of the phenomenon of resonance. Control of the resistance applied by the hydraulic cylinders allows generation to be maximised when waves are small, and the machine response to be minimised in storms. Importantly, the default or natural condition of the machine is benign and non-resonant, and so inherently capable of dealing with extreme conditions.

How does a laptop charger operate?
The parts of a laptop charger are: the Wall to converter cable, the power converter, the converter to the PC cable and the plug. It operates by the plug passing energy or electricity to the wall to converter cable. The wall to converter cable then passes the energy to the converter. Finally the converter passes on the energy to the PC through the plugged in head connected to the laptop and it's charged.
Is man an energy converter?
yes
What is an example of an electric motor?
An electric motor is an example of an electro-mechanical energy converter. It takes electrical energy and converts it into mechanical energy, which is used to do work such as rotate a fan or drive an electric vehicle.
