From Steve Johns
I was dismayed by the report on the wind turbine explosion in Scotland that happened because high winds forced it to turn against the brakes (13 July, p 7). What dismayed me was not the incident itself or the ammunition it provided to the anti-wind lobby, but the engineering solutions recommended to prevent it happening again.
The turbine operator says that fireproof materials, sensors and built-in extinguishers should work. But why not just use locking pins? This simple mechanism prevents any possibility of rotation. Sometimes high-tech solutions are not the best.
