Wind energy is powering a community of people castaway on a deserted Hebridean Island for a television documentary. Twenty-eight adults and eight children volunteered to spend a year away from the trappings of modern life on the windswept island of Taransay. Their experiences will be seen on the BBC's program "Castaway 2000." A Proven 2.5 kW machine will provide basic electricity needs including lighting, a computer and satellite telephone. Kilmarnock based manufacturer Proven Engineering says a wind turbine of this size would normally power just a single family. It was installed on the island shortly before Christmas, in time for the community's arrival to see in the New Millennium.
