Re: [a-w-h] rooftop WT
- I know that you're talking to Hugh here, but this "you can still go ""green"" by putting a rooftop VAWT up in LA" is one of the silliest things said on this list in quite a while. I never thought I'd see the day when just hearing the word green would make me cringe.
If someone really wants to do something helpful, instead of simply consuming more resources to make themselves feel good about their own excesses, and they live in a place with a class 1 wind resource, go with PV - or better yet, with solar thermal! Small wind turbines can be great, provided they are used in a place with the wind to make them operate usefully. LA is not that place (unless you happen to live in the San Gabriel Mountains and on a ridge)

That's a good story from my point of view. They're not technical people who loved to see their electrical bills reduced even by a quarter. Renters of 'Flats' building are happier too.

Doug's one doesn't count because his story is about a concrete commercial building in Tehachapi which is not a typical site. Also of course it is his own turbine... OK, sorry that's not fair, Doug's one counts - they all count - bring them flooding in please.
> What we need on this list are exciting and positive stories about vertical axis and rooftop turbines so that I can shut up and go away and stop being negative all the time. The snag is that they have to be real stories, and not computer generated graphics and projections. Ideally, they ought to also include lots of data such as XXX kWh per day and such and such windspeed.

Hopefully the said entrepreneurs will not be the only people submitting stories to the list.

- It may be that the electricity most nearly affordable to the average
homeowner will come from a megawatt wind turbine sited where strong
Technologies mature. There haven't been any revolutionary changes in
aviation in the last fifty years, though there have been incremental
Mass production could reduce the cost of electricity from small wind
turbines, but the market for them is limited by the fact that most
people do not live where there is most energy in the wind and they
never will as long as most of us who might buy wind turbines live in
cities. Buildings reduce the local wind energy resource.
Also, there is no point in producing noisy or unreliable or
unproductive wind turbines cheaply, and no one will pay for them.
Many people will continue to be subsistence farmers living in valleys
where the land is productive but the wind is weak.
