Hi.
Thanks Sam! Didn't appreciate the difference, we had windmills which were used for grinding wheat etc here but those were the traditional cone shaped building things with huge sails.
You're welcome.
I've been facinated about wind power as long as I can remember, I must've been about 12 when I made my first Savonius out of a bicycle dynamo and cut in halves beer can

.
We didn't have elecricity in our archipelago summer cottage, and I envisioned a 200L oil barrel Savonius wind generator to produce enough power to run the lights.
Then my parents had a land-line installed .
There's plenty of designs and all of them are pretty much designed to perform a specific task in a specific conditions/environment.
The engineering behind the various designs is hundreds, if not thousands of years old, and work pretty darn well in the task they were originally intended, having been perfected for hundreds of years.
The problems and misconceptions arise when people try to use the incorrect tool for the job or when they believe the marketing departments outrageous claims.
Fortunately for us, the 'net provides us with all the data we need to make an informed desicion about the most suitable one for our location and application.
What ever that application may be.
I wasn't aware of little ones like mellowinman's in use here for a specific purpose that I can recall, must do some reading, interesting.
The Wikipedia is IMO a good place to start, the links will reveal weeks worth of reading.
Unfortunately when You're done reading both the good and the bad with an open mind, the wind power in its current form will not look quite as great as the tree-huggers want us to believe.
But then again, none of the renewable resource energy options in their current form will.
Regards
Sam
