to Patagoniax> First, your report has proven my suspicions regarding whether a Wind generator will be a feasable task. Secondly, your report confirms my understanding of using a windmill that narrows choices to the larger blades of 5 metre plus, certainly a structure we prefer not to expose into our community scenery. Likewise, it would be even just as much a nuisance image to have multiple windmills in series along the hillside scene. Your figures of each windmill seems logical and gives cause for me to abandon this task. I will add comments after this to the subject of the fuel Generators and/ using Transformers to 50hZ and 60hZ.patagoniax wrote:.
In the course of looking up solutions, reliability data, and whatnot for a wind turbine solution for your situation, I came upon some studies done in Holland -- certainly a windy place much of the time -- by a government agency we will charitably call the Dutch Patagoniax, or Captain Bringdown. Their findings, well, let's look at the numbers and the assumptions. Your specs called for smallish diametre blades so I will throw in the blade specs here as well, but with a note that the larger the blades, generally the better the performance, at least in this test. No surprises there. The best-performing solution here involved the largest diametre blades (sometimes bigger really is better).
Average Dutch household consumes 3,400 kWh/year.
Average wind velocity in test area:
3.8 m/sec or about 8.5 mph
Sample products and annual production:
- "Ampair 600" (8,925 euro, 1.7 metre blade diametre ) : 245 kWh per year or an average real-world output of 28 watts. 14 of these wind turbines would be needed for the full electrical consumption of 3400 KWh for a year, not counting any conversion losses if battery storage, etc., were used. 14 such windmills would cost about 125,000 euro.
- "Airdolphin" (17,548 euro, 1.8 metre blade diametre) : 393 kWh per year or an average output of 44.8 watts. 9 such windmills would be required (about 158,000 euro).
- "WRE 060" (37,187 euro, 2.5 metre blade diametre) : 485 kWh per year or an average output of 55.4 watts. 7 such windmills would be required (260,000 euro).
- " Montana" (18,508 euro, 5 metre blade diametre) : 2,691 kWh per year or an average power output of 307 watts. 2 such windmills, 37,000 euro.
Origin of data - note that I just picked a few of the tested turbine models as representative of the turbine blade size ranges. Check the math, if need be.

When you try a task and it seem unlogical, try another: yup and stay happy.
