Wind turbines, do they affect radio and TV

[Aerodyne]

John, I believe you have a valid point about the efficiency of wind farms. For my OU thesis I wrote about sustainable power sources and found that tidal power is both more efficient and more reliable than wind power and probably less expensive in the long run re maintenance. Initial costs are high and there's always the environmentalist lobby to take into account, but barriers across the Severn estuary, Morecambe Bay and the wash would potential provide far better return for investment and definitely be less visually obtrusive - nor would a barrier affect TV reception...
