Re: Jim Bray, Questioning exploding bat lungs, The Tribune, Letter, March 13
If Mr. Bray had bothered to research the Divers Alert Network (DAN), one of the most respected dive organizations worldwide, or even consulted any of the dive certification organizations, such as PADI, NAUI, SSI, etc. he could have easily confirmed that ‘barotrauma’ is a real word.
It is used to describe pnuemothorax, air embolism and other decompression sicknesses. I do agree with him that purely relying on Wikepedia is not real ‘research’ so I have to wonder why he chose that way at all.
Wind energy worldwide, with existing technology, is a growing disaster, not just here in Ontario. There have been millions of bat deaths recorded worldwide.
It is possible some of those deaths, like those of the many birds killed, may have been caused by impact with a turbine blade. It is certainly recorded that in many cases the cause has been barotraumas, causing bats lungs to explode.
Like the wind energy companies Mr. Bray continues the myth that mechanical noise is the only noise issue with Industrial Wind Machines.
They continue to ignore the mounting evidence of serious long term and accumulative negative health effects caused by low frequency and infrasound of which a marked pressure fluctuation is an element.
Physics 101 should tell Mr. Bray that a turbine blade will only turn when wind hits one side. To convert that into the kinetic energy required there should be little or no ‘wind’ effect coming from the other side of the blade.
In fact if they ever could produce an efficient IWM there would be a near vacuum on the side away from the wind.
When high pressure is adjacent to low pressure under these conditions there is most certainly a large, continual and measurable pressure fluctuation created by these IWMs.
It is this effect that causes the noises that have been frequently described by some forced to live too close to IWMs as the persistent ‘whoosh, whoosh’ or the sound of ‘jet engines’.
