waveHaving noted that a cork bobs around in water, research scientists set about designing a machine which could convert
wave power into electricity. Manchester University hydrodynamics professor and inventor Peter Stansby (pictured below) came up with the
Manchester Bobber - a rig with semi-submerged floats which move up and down with the passing of waves operating a pulley which spins a fly-wheel connected to an induction electricity generator.
Over the last couple of years 1/100 scale (2004) and 1/10 scale (September 2005) operational models have been tested extensively and the results have been very positive.
When scaled up to commerical dimensions a rig like the one illustrated above could generate an average of 5 MW - more than the maximum power output of the
World's largest offshore wind turbines - with outputs far in excess of 5 MW possible in heavy seas.
The Manchester Bobber
One advantage of the Manchester Bobber over other
wave power generarators is the simplicity of the system and its robust nature. Only the floats come into contact with the water with all mechnical and electrical components housed safely above the surface of the water on the rig. This makes
maintenance far easier, cheaper, and less frequently required. In addition, the floats can rapidly be filled with water in heavy storms to reduce the magnitude of the oscillations and protect the system from damage.
Pictured below is the 1/10 scale
drive train used in testing the
Manchester Bobber prototype system. This converts the up and down oscillations of the floats in the water into rotational energy which is passed through a gear-box
to the electricity
generator.
