Ocean waves move air in and out of chambers in a breakwater, which in turn drives a turbine from Inverness-based Wavegen, known as the Wells turbine, to generate electricity. It is the first commercial wave farm in Scotland and is starting with a capacity to power around 1,800 homes Alex SalmondFirst ministerOcean waves move air in and out of chambers in a breakwater, which in turn drives a turbine from Inverness-based Wavegen, known as the Wells turbine, to generate electricity.

Stephen Salter, a professor of engineering design at the University of Edinburgh and a leading expert on renewable energy said that wave power had the potential to provide 100kw of power for every metre of ocean -- amounting to a big conventional power station for every 10km of shoreline.
At 4mw of power the Lewis wave farm will be able to power around 1800 homes -- a thousand times less powerful than a conventional coal fired Drax power station.
Even so Prof Salter said he believed the Lewis project to be the largest wave farm in the world, adding: "It is still small but the longest journey starts with a single step."
