Am I alone in liking wind turbines? Travelling in France recently I've seen many of these graceful structures. 

What are the rules for installing smaller ones on homes to help power ham gear?

BTW back home tomorrow so should be testing on 137kHz next week.

Hi all,
Off topic I know, but whatever about magnetic effects, I agree with Mal when it comes to the appearance of these things. They are gradually ruining the best countryside in the UK. Mind you, the national grid pylons are not much better, would have been well worth the extra cost to bury the cables in my opinion. These turbines are relatively inefficient when you take evrything into account. It's the government trying to meet some ludicrous target re 'green' electricity generation. The sooner the hype dies down and we go back to nuclear power the better I say.

Seems unlikely that the magnetism would reach that far to me - the magnetic field would be no different to any other large generating set - they are just an ordinary alternator driven through a gearbox.
If they did affect magnetic compasses you would have thought that the place you would really notice it would be around the coast, with small boats sailing in amongst them.
Although they look as if they are turning slowly, they can't do many rpm before the tips of the blades go supersonic, as the blades are many 10s of metres long.
Over what distance did you notice the magnetic effect? perhaps I could get down to the ones on Romney Marsh, here in Kent and see if they have any effect on a compass needle.
 
The moving blades can affect radio reception for people living nearby, although I've not noticed this myself.

Great for LF!!!!!!!!!!!!!
 
Experience
 
Driving to Gleneagles in Scotland last weekend my car magnetic compass was reading backwards and erratic and I wondered why.
The hills es mountain tops are covered with WIND TURBINES,  hugh beasts and only turning slowly, cannot be producing much electric.
however thinking about it I have concluded that the strong MAGNETS in the turbines must effect a magnetic compass,  possible aeroplanes as well except they are flying very high, might also have an influence on GPS frequencies and navigation in these areas
I must say these hugh Monsters strewn all across the Scottish mountain tops and countryside spoils the scenery.
