On the evening of 24 August, the Quest TV channel broadcast an item called 'Destroyed in Seconds'. It showed a wind turbine in Denmark being literally blown apart,very rapidly indeed. Apparantly, in responding to a sudden wind squall, this turbine was unable to turn itself off due to a failure of its braking system. Large chunks of debris were flung into the air and passed over the roof of a house way beyond the 400 metre safety radius, according to the resident; luckily nobody was hurt because there was a few minute's notice before the event.
This incident has implications for the current Bryn Llwelyn proposal to place turbines near the Mountain Road leading from Llanllwni. RES, has stated that nobody has ever been hurt by the normal operation of a wind farm but in real life, abnormal things happen including lightning strikes, ice build up, blade or bearing failure as well as extreme weather. There have been a numberof these instances in recent times all over Europe as well as in the U.K., sometimes leading to unquenchable fires.
In this local case, if granted peremission, there would be 2 giant turbines 250 and 300 metres from the Mountain Road on its windward side so that any passing traffic or parked tourists in the area would be put at extreme risk from turbine failure. Worse still, there is no proposal to fence off any of the planned 21 giant turbines from the public or grazing animals so the risk of injury would be widespread to put it mildly! All this despite the fact that guidelines from a well known wind turbine supplier organisation in their Wind Turbine Mechanical Operating and Maintenance Manual state "Do not stay within a radius of 400 metres from the turbines unless it is necessary".
It is clera to me that, for a number of reasons, if we really needto have these giant industrial machines despoiling our countryside, they should be placed at least 2 kilometres from any human occupation and the turbines themselves should be surrounded by fencing at least 750 metres away. Anything less than these measures would be a clear breach of public health and safety - it seems that RES have not heard of the precautionary principle!
