There's all kinds of trade-offs with small wind, not the least being site considerations. This is where a VAWT may be a better choice. It certainly won't produce as much power as conventional HAWT if similar sized, but it will keep neighbors and the local regulatory bodies happier.
Another trade-off between VAWT and HAWT is that wind speed increases quite a bit with height. What you can get at 30' maybe almost double what you can get at 10'. I have a mast that is about 15' above grade. I'm not doing it as an option for house power and like to keep the neighbors happy, otherwise I would have a larger prop set and increase the height to 30+ ft..
There are a lot of myths about wind power and there is always someone trying to build a better mousetrap, mostly to counter the myths. Maybe we'll get advancements in material sciences in the future that will enable use of lighter wind capturing devices. That will open the door to homeowners that live in windy areas and make wind power less of a hassle and more of a bonus.
