Prototype wave-powered electricity generator under evaluation near Portnahaven on the island of Islay,Scotland. The device is built at the head of a natural rock gully and encloses a column of sea water. Waves entering the gully are channeled in towards it,causing the column of water to rise and fall. This forces air through a Wells turbine,which turns in the same direction whichever way the air is flowing,driving a 200 kilowatt electricity generator. The device was designed and developed by researchers at Queen's University,Belfast,and will eventually be used to supply electricity to small,isolated communities | |
