"As for turbines making people ill, I don't like them, they are ugly and noisy and expensive, but making people ill?"
Actually, in theory they can (or at least make people feel ill), but it would be dependent on varying conditions such as wind speed.
Engineers might understand the first issue: Harmonics. Sound waves can induce nausea, headaches and other 'illnesses' if they're at the right frequency and exposure is maintained for a period of time.
Magnetic fields can cause problems, too.
Flickering from the blade rotation can affect some people.
Vapor from lubricants, paints and other chemicals can cause a feeling of illness.
Of cause, as I noted at the start, all the above are dependent various conditions, and these include proximity to the source, and most can easily be avoided or prevented. As such, they generally apply to people working on the wind farms more than people in the surrounding area. The only exception is harmonics, which vary depending on wind speed. The drone from the turbines is reported to cause disturbance to sleep patterns which can lead to illness. This has been reported by people living in valleys where wind farms have been sited, and by people living close to the turbines. It is a common argument presented to oppose a new wind farm being erected.
Thing is, a small scale study will be unlikely to uncover the truth. It would take a long term study to find out what the health implications are and those are expensive. I believe, however, that such studies are being undertaken, funded by people on both sides of the fence, so to speak. It will be interesting to see what the outcome is, but I'm predicting a bun fight.
