Wave Star Machine
The Wave Star machine represents a solution to both the trivial and complex problems which, for years, have stood in the way of the development of commercially viable wave power technology. The basic concept behind Wave Star is fundamentally different to many other wave power models. The machine does not form a barrier against the waves, with a view to harnessing all of their energy, but instead cuts in at right angles to the direction of the wave. In this way the waves run through the length of the machine, and their energy is exploited in a continuous process. On either side of the oblong machine there are 20 hemisphere-shaped floats which are partially submerged in the water. When a wave rolls in, the first float is lifted upwards, and then the second and so on, until the wave subsides. The floats are each positioned at the base of their own hydraulic cylinder. When a float is raised, a piston in the cylinder presses oil into the machine’s common transmission system with a pressure of up to 200 bar. The pressure drives a hydraulic motor, which is connected to the generator, which produces the electricity. As the machine is several wave lengths long, the floats will work continuously to harness energy. A Wave Star machine is manufactured in its entirety on land, and then tugged out to the steel piles upon which it is to rest. The tugging is a relatively simple procedure, as the weight of the machine is carried by its own floats. The machine is positioned over the steel shaft, and then the float arms are raised, until it is resting on the shaft, where it is bolted on. When the machine is due to be serviced or requires repair, it is loosened and tugged back into land. As Wave Star produces electricity via 40 independent floats, there is not a lot that can go wrong. If one float breaks, the remaining 39 continue to generate electricity. The machine can continue to generate electricity, albeit with a reduced effect, with up to 75 percent of the floats out of operation.
