Wave Energy - power from the waves - marine Energy - Wave Power - Ocean Energy 

Human population.
Guy Lane: Most of our lovely planet is covered in sea water and most of the humans live within a transmission line's distance from the coast, and the waves are quite predictable and so it is no surprise that there are a pile of awesome machines designed to tap the energy of the waves and these machines are characterised by being BIG and TOUGH and POWERFUL and the world leaders are the Scottish and I say Viva Marine Energy and Scotland.

Seatricity

Sea Clam wave energy 
The early circular configuration of the SEA clam was a simple device that used the displacement of air to extract energy from sea waves. Twelve air chambers, the outer faces of which are formed by flexible rubber membranes, were placed around a floating ring structure. Differential wave action moved the membrane in and out forcing the air to be interchanged between chambers.

S.D.E. wave buoy
S.D.E. is a world leader in the planning, building and marketing of power stations which produce power from sea waves. SDE's method consists of using the motion of sea waves to generate hydraulic pressure, which is then transformed into electricity. The system takes advantage of the wave's speed, height, depth, rise and fall, and the flow beneath the approaching wave, thus producing energy.

Green Wave Energy Group
Our turbine consists of nothing more than a structurally reinforced fiberglass cylinder with a large propeller (or impeller) inside that’s connected to an electric generator. No oil or hydraulics are involved. The turbine is vertically anchored into a fixed spot with just its top peeking out of the water.  The generator’s production relies on the water rising and falling inside the cylinder, to turn the propeller and generate electricity.

Wetpos Wave Energy Converter
Through its floating angular construction, the Wetpos wave energy converter is able to regulate the wave energy input and reduce the impact during rough weather conditions. The V‐shaped structure absorbs the wave energy through a line of rotors, which each of them transmits the energy to a common axle, directly attached to a generator.

Wavestar - unlimited clean energy
The Wavestar machine draws energy from wave power with floats that rise and fall with the up and down motion of waves. The floats are attached by arms to a platform that stands on legs secured to the sea floor. The motion of the floats is transferred via hydraulics into the rotation of a generator, producing electricity. Waves run the length of the machine, lifting 20 floats in turn.

Snapper wave electrical generator
The concept of the Snapper electrical generator arose during attempts to overcome a fundamental difficulty of wave power generation. Electrical generators produce power as a result of the movement of an applied force. The size, weight and cost are all related to the magnitude of the force but the power is related to speed as well.
