Windmills small and quiet enough for every rooftop could boost green energy, but they're still pricey. New deals could change that.

Sounds a good idea, but remember that wind works better on hills in open country rather than on roofs in built up areas.
10,000KWH is worth very roughly from £1,000 to £2,000, if it really does produce that much it might be economic.

Sounds great, but price is £35k approx. installed - this is expensive for a 6KW WT.
Won't be many buyers at that sort of price. My search goes on......

looks like fansinating. But the website does not provide rated power. 7.4kw at 14m/s, 4.2KW at 11m/s is a too ambiguous. Probably desigened for 6KW.
If so, 14m/s as cut-out speed is too lower, meaning more energy unable to be absorbed if wind is good. Not very suitable for Scotland areas.
And the prices, a bit luxuary.
Does not know the control system and inverter details, all these needs time testing.
Vertical models seems very hot recently. Quite suitable for urban areas. But still involves viberation and noise anyway.
