J. \-abating. Either because of a limitation of resource, or because of the impact of their exploitation, there is a desire to replace the sources of energy to which we have become accustomed since the industrial revolution with a more sustainable alternative. A renewable energy source is one which does not use up the earth's finite mineral reserve and instead uses a source which replenishes itself. Around two thirds of the earth's surface is covered in water, it is therefore logical to look here for usable energy.

The work presented here is intended to add to the increasing body of research on the subject of capturing energy from the marine resource. It focuses on the aspects associated with converting the captured energy, in the form of physical displacement, into an electrical form and therefore stops short of the development of the capture device itself and the downstream connection to the electricity grid.

In summary this thesis is concerned with the development of reciprocating generators capable of delivering the required power at the slow velocities demanded by wave energy and tidal stream power converters. Research into such generators facilitates the use of direct drive power take off, whereby the electrical machine is joined directly to the moving part of the device.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
